Machining Delrin: A Plastics Guide

March 1, 2019

An Informational Brief on Polymer Machining

Delrin®, also commonly known as an acetal (polyoxymethylene) homopolymer, is an impact and wear resistant semi-crystalline thermoplastic popular for a broad range of machining applications. To list just a few of its impressive qualities, Delrin offers great stiffness, flexural modulus, and high tensile and impact strength.

Our latest machining guide discusses what goes into machining Delrin and how its considerations differ from other manufacturing options such as metal machining, injection molding, and 3D printing.

How does AIP approach Delrin and its machining process? To start, we’ll explain the difference between machining Delrin, a thermoplastic, and machining thermosets.

Machining Thermoplastics vs Thermosets

We’ve already said that Delrin is a thermoplastic, but what does that mean exactly?

All polymers can more or less be divided into two categories: thermoplastics and thermosets. The main difference between them is how they react to heat. Thermoplastics like Delrin, for example, melt in the heat, while thermosets remain “set” once they’re formed. Understanding the technical distinction between these types of materials is essential to CNC machining them properly.

What type of thermoplastic is Delrin in particular? Acetal homopolymer is a semi–crystalline, engineering thermoplastic.

Properties & Grades of Machined Delrin

This strong, stiff and hard acetal homopolymer is easy to machine and exhibits dimensional stability and good creep resistance, among several other desirable qualities. Delrin is also known for its superior friction resistance, high tensile strength, and its fatigue, abrasion, solvent and moisture resistance.

The latter quality allows Delrin to significantly outperform other thermoplastics like Nylon in high moisture or submerged environments without losing high-performance in the process. In other words, Delrin can retain its low coefficient of friction and good wear properties in wet environments.

One of the main reasons for Delrin’s popularity is its sheer versatility. The above blend of unique qualities makes Delrin broadly applicable to various industries in the medical, aerospace and energy sectors. For example, you can machine Delrin for medical implants and instruments, or for industrial bearings, rollers, gears, and scraper blades. It is ideal for smaller applications at temperatures below 250 °F (121°C) and can have centerline porosity.

Some of the Delrin grades we regularly machine at AIP include:

PTFE-Filled Acetals

PTFE (polytetrafluoroethylene) filled grades of Delrin is ideal where impact strength and wear capability are of the highest importance.

Glass-Reinforced Acetals

Acetals that are reinforced with glass have a much higher strength and greater heat resistance than other grades of Delrin.

FDA-Compliant Acetals

There are FDA-compliant grades of Delrin available for use in medical and food-related applications.

Machining Delrin

It’s true that Delrin is an easy material to work with in terms of machining. It is a very stable material, which makes precise, tight tolerances easier to achieve for this thermoplastic.

While machining, keep in mind that Delrin is sensitive to heat at or above 250 °F (121°C).

Balance the material removal as best as you can to keep your dimensions stable.

We also suggest non-aromatic, air-based coolants to achieve optimum surface finishes and close tolerances. Coolants have the additional benefit of extending tool life as well.

Preventing Contamination

Contamination is a serious concern when machining polymer components for technically demanding industries such as medical and life sciences. To ensure the highest level of sanitation down to the sub-molecular level, AIP Precision Machining designs, heat-treats, and machines only plastics, with any sub-manufactured metalwork processed outside our facility.

Machining PPS: A Plastics Guide

August 30, 2018

An Informational Brief on Polymer Machining

Did you know that PPS (or Polyphenylene sulfide) products offer the broadest resistance to chemicals of any high-performance thermoplastic? It’s no surprise that this makes them a popular choice for industrial applications such as wheel bushings, chemical pumps, and compound clamp rings for semiconductor wafers.

What goes into machining this thermoplastic, however, and how does it differ from metal machining, injection molding, or 3D printing?

With Machining PPS: A Plastics Guides, AIP provides you with a guide to this material and its machining process. First, let’s start with the basics: thermoplastics vs thermosets.

Machining Thermoplastics vs Thermosets

We’ve already said that PPS is a thermoplastic, but what does that mean exactly?

All polymers can more or less be divided into two categories: thermoplastics and thermosets. The main difference between them is how they react to heat. Thermoplastics like PPS, for example, melt in heat, while thermosets remain “set” once they’re formed. Understanding the technical distinction between these types of materials is essential to CNC machining them properly.

What type of thermoplastic is PPS in particular? It’s a semi-crystalline, high-performance thermoplastic that has an extremely stable molecular structure. The chemical resistance of PPS is often compared to PEEK and fluoropolymers.

Properties & Grades of Machined PPS

There’s a lot to like about PPS’s material properties. As we mentioned before, PPS has exceptional chemical resistance that makes its bearing grades especially favorable for the chemical industry or caustic environments. In particular, its resistance to acids, alkalis, ketones, and hydrocarbons lend PPS stellar structural performance in harsh chemicals.

Additionally, PPS materials are inert to steam as well as strong bases, fuels and acids. Combine that with a low coefficient of thermal expansion and zero moisture absorption, and you get a material that is ideal for continuous use in corrosive or hostile environments. PPS has replaced stainless steel for a lot of industrial applications for this reason.

Most impressively, PPS will not dissolve at temperatures below approximately 200 °C, no matter what solvent is used. In fact, all grades of PPS share UL94 V-0 flammability ratings, without requiring flame retardant additives, resulting in an excellent material for aircraft where flame resistance is paramount.

Some grades of PPS that we regularly machine at AIP Precision Machining include Ryton®, Fortron®, TECHTRON®, TECTRON® HPV, TECATRON PVX and TECATRON CMP.

Machining PPS

Annealing PPS

The process of annealing and stress-relieving PPS reduces the likelihood of surface cracks and internal stresses occurring in the material. Post-machining annealing also helps to reduce stresses that could potentially contribute to premature failure. AIP’s special annealing process for PPS is designed to take the specific properties of PPS into account, and we advise anyone working with PPS to hire a manufacturer that understands its unique demands.

Machining PPS

PPS is a fantastic material for machining. Its low shrinkage and stable dimensional properties make it easy to machine to incredibly tight, precise tolerances. A unique characteristic of PPS is that when dropped, it sounds just like a piece of metal hitting the floor.

PPS, like many other thermoplastics, is notch sensitive, so take care to avoid sharp corners in design. We recommend carbide tipped cutting tools for working with PPS as they provide an ideal speed and surface finish.

We also suggest non-aromatic, water-soluble coolants, such as pressurized air and spray mists, to achieve optimum surface finishes and close tolerances. Coolants have the additional benefit of extending tool life as well. No known coolants attack nor degrade PPS.

Preventing Contamination

Contamination is a serious concern when machining polymer components for technically demanding industries such as aerospace. To ensure the highest level of sanitation down to the sub-molecular level, AIP Precision Machining designs, heat-treats, and machines only plastics, with any sub-manufactured metalwork processed outside our facility.

Plastics in Aerospace: The Secret to Fuel-Efficient Aircraft

July 19, 2018

How Aluminum Got Dethroned by Thermoplastics in Aerospace

Cup holders. Magazines. Suit cases. Aircraft engines. Here’s a riddle, what do these items all have in common? If you’re an aircraft operator, the answer is obvious: they all add weight, making them a drain on your fuel costs.

If weight is one of the main operating costs of an aircraft, then it’s no surprise that airlines want to lose a few pounds. Over the last 35 years, AIP has witnessed firsthand the incredible weight savings that can be gained from using lightweight polymers and composites for aerospace applications.

How Airlines “Slim Down” Operating Costs

How much can an ounce cost you? Plenty. In the case of United Airlines, removing a single ounce from its in-flight magazine has translated to saving $290,000 a year. Yes, a single ounce can hit an airline with up to six digits in costs.

If thinner paper can have such an impact on your bottom line, then you can imagine the significant cost savings that can come from manufacturing lighter aerospace components. What’s the most lightweight solution for aircraft operators today? We have one word for you: plastics.

What Makes Plastics the Secret to Aircraft Fuel-Efficiency

Aluminum was popular during the “Golden Age of Aviation” because of its strength and durability as well as its lightness when compared to other metals like steel. As a result, many aircraft components have traditionally been metal, from aircraft interiors, to landing gear, aircraft engines and structural components.

Now consider the fact that polymer and composite materials can be up to ten times lighter than metal. It’s no wonder that as more thermoplastic materials come on the market and new manufacturing opportunities arise, metal replacement has been seen as one of the best opportunities to reduce airline weight.

How big is the impact of switching from aluminum to plastic parts like PEEK and ULTEM in aerospace applications? Operators can earn weight savings of up to 60%. This translates to lower lifetime fuel costs, reduced emissions and extended flight range for operators.

“Weighing” the Option of Plastics in Aerospace

Weight alone is a massive reason to consider thermoplastics for aerospace, but weight isn’t the only factor at play in material selection.

After all, wood is lighter than metal, but there’s a reason we don’t build spruce airframes like the first plane from the Wright brothers: it wouldn’t be safe today to fly a wooden plane! Aerospace components need to be able to survive in corrosive, harsh environments as well as provide resistance to high temperatures.

In other words, it’s crucial that your mission-critical components aren’t just lightweight, but also high-performing.

At AIP, we carefully apply our decades of material expertise to select the right material for your application’s needs. Remember that your aerospace plastics manufacturer should understand the unique demands of your industry and your application, and have experience machining the material you require.

Machining TORLON: A Plastics Guide

May 30, 2018

An Informational Brief on Polymer Machining

AIP Precision Machining has worked with many thermoplastics over the past three decades, including TORLON: a PAI, or polyamide-imide, engineered by Solvay Specialty Polymers.

Due to its reliable performance at severe levels of temperature and stress, TORLON is ideal for critical mechanical and structural components of jet engines, automotive transmissions, oil recovery, off-road vehicles and heavy-duty equipment.

AIP has over 35 years of experience machining complex components from TORLON and various other thermoplastic materials. We are providing this Machining TORLON Guide as yet another insightful technical brief about our polymer component manufacturing process, and how it differs from that of metal machining, injection molding, or 3D printing.

Plastic CNC Machining

Before discussing the process of machining TORLON, it’s important to understand exactly what plastic machining is.

CNC (Computer Numerical Control) machining is a process in the manufacturing sector that involves the use of computers to control machine tools. In the case of plastic machining, this involves the precise removal of layers from a plastic sheet, rod, tube or near net molded blank.

The early history of CNC machining is almost as complex as a modern CNC system. The earliest version of computer numerical control (CNC) technology was developed shortly after World War II as a reliable, repeatable way to manufacture more accurate and complex parts for the aircraft industry. Numerical control—the precursor to CNC—was developed by John Parsons as a method of producing integrally stiffened aircraft skins.

Parsons, while working at his father’s Traverse City, Michigan-based Parsons Corp., had previously collaborated on the development of a system for producing helicopter rotor blade templates. Using an IBM 602A multiplier to calculate airfoil coordinates, and inputting this data to a Swiss jig borer, it was possible to produce templates from data on punched cards.

Parsons’ work lead to numerous Air Force research projects at the Massachusetts Institute of Technology (MIT) starting in 1949. Following extensive research and development, an experimental milling machine was constructed at MIT’s Servomechanisms Laboratory.

Due to the many different kinds of polymers and composites, it’s important to have strong technical expertise of polymer materials when machining plastic components; some plastics are brittle, for example, while others cut similarly to metal. The challenge of plastics is their wide range of mechanical and thermal properties which result in varying behavior when machined. Therefore, it’s important to understand the polymer structure and properties of TORLON if you’re machining it.

Thermoplastics vs Thermosets

When it comes to polymers, you have two basic types: thermoplastics and thermosets. It’s crucial to know which one you’re working with due to distinct differences between how these two main polymer categories react to chemicals and temperature.

Thermoplastics soften when heated and become more fluid as additional heat is applied. The curing process is completely reversible as no chemical bonding takes place. This characteristic allows thermoplastics to be remolded and recycled without negatively affecting the material’s physical properties.

They possess the following properties:

• Good Resistance to Creep

• Soluble in Certain Solvents

• Swell in Presence of Certain Solvents

• Allows for Plastic Deformation when Heated

Thermosets plastics contain polymers that cross-link together during the curing process to form an irreversible chemical bond. The cross-linking process eliminates the risk of the product re-melting when heat is applied, making thermosets ideal for high-heat applications such as electronics and appliances.

They possess the following properties:

• High Resistance to Creep

• Cannot Melt

• Insoluble

• Rarely Swell in Presence of Solvents

Phenolic, Bakelite, Vinyl Ester and Epoxy materials would be considered examples of a thermoset, while ULTEM, PEEK, DELRIN and Polycarbonate materials are examples of thermoplastics.

The thermoplastic category of polymers is further categorized into Amorphous and Crystalline polymers per the figure below:

TORLON is considered an amorphous, high-performance thermoplastic. Most amorphous polymers are thermoform capable, translucent and easily bonded with adhesives or solvents.

Various Grades of Machined TORLON

What makes TORLON unique is how it possesses both the incredible performance of thermoset polyimides and the melt-processing advantages of thermoplastics. The compressive strength of (unfilled) TORLON PAI is double that of PEEK and 30% higher than that of ULTEM PEI. In fact, TORLON is considered the highest performing, melt-processible plastic.

High-strength grades of TORLON retain their toughness, high strength and high stiffness up to 275°C. This and its impressive wear resistance allow TORLON to endure in hostile thermal, chemical and stress conditions considered too severe for other thermoplastics. TORLON is also resistant to automotive and aviation fluids, making it a favorite of aerospace and automotive engineers.

One concern of using TORLON is that its moisture absorption rate is not as low as other high-performance plastics, so special care should be taken when designing components for wet environments.

There’s more than one particular type of TORLON PAI you can machine, and each has slightly different properties for perfecting this material’s use in different applications.

Here are several grades of TORLON PAI we machine regularly at AIP Precision Machining.

TORLON 4203

TORLON 4203 is the unfilled or natural grade of TORLON PAI that outperforms other grades with the best impact resistance and the most elongation. TORLON 4203 PAI can be used for a variety of applications but due to its good electrical properties, it is commonly machined for electronic equipment manufacturing, valve seals, bearings and temperature test sockets.

TORLON 4301

TORLON 4301 is a wear-resistant grade of TORLON PAI containing PTFE and graphite. It has high flexural and compressive strength with a low coefficient of friction, as well as good mechanical properties. Typical applications of 4301 are anything that requires strength at high temperature with wear resistance and low friction. This material is useful for parts such as thrust washers, spline liners, valve seats, bushings, bearings and wear rings.

TORLON 4XG

TORLON 4XG is a 30% glass-reinforced extruded grade of PAI well suited to higher load structural or electronic applications. When you need a high degree of dimensional control, this grade offers the high-performance you need. Various uses of TORLON 4XG include burn-in sockets, gears, valve plates, impellers, rotors, terminal strips and insulators, among others.

TORLON 4XCF

TORLON 4XCF is a 30% carbon-reinforced extruded grade of PAI that has the lowest coefficient of thermal expansion and the most impressive fatigue resistance of all plastic materials. This uncommon grade works well as a replacement for metal applications as well as mission-critical aerospace components, in addition to impellers, shrouds and pistons.

Machining TORLON

Annealing TORLON
TORLON PAI can be received in the form of rods, sheets, tube or film. Stress-relieving before machining through an annealing process is crucial, as it reduces the likelihood that surface cracks and internal stresses will occur from the heat generated. This also helps prevent any warping or distortion of your plastic materials.

TORLON additionally benefits from post-machining annealing to reduce any stress that could contribute to premature failure. Extruded TORLON parts, such as those machined from TORLON 4XCF and TORLON 4XG, benefit from an additional cure after machining to further enhance wear resistance; this is unique to PAI. Proper annealing of Torlon can require more than seven days in special ovens at AIP.

If the machine shop you are working with does not have a computer controlled annealing oven for plastics, then “head for dee hills” as they are obviously not TORLON machining experts.

Machining TORLON

An important consideration to have when machining TORLON PAI is how abrasive it is on tooling. If you’re machining on a short run, carbide tooling can be used, but polycrystalline (PCD) tooling should be considered for lengthier runs, machining for tight tolerance and any time you are working with reinforced grades.

Another thing to keep in mind when machining extruded TORLON shapes is that they have a cured outer skin, which is harder than interior sections. The outer skin offers the best wear and chemical resistance. If wear resistance and chemical resistance needs to be optimized, extruded TORLON should be re-cured.

TORLON PAI will nearly always require the use of coolants due to its stiffness and hardness. Non-aromatic, water-soluble coolants are most suitable for ideal surface finishes and close tolerances. These include pressurized air and spray mists. Coolants have the additional benefit of extending tool life as well.

Many metal shops use petroleum-based coolants, but these types of fluids attack TORLON. Many past experiences have shown parts going to customer without cracks, only to develop cracks over time due to exposure to metal machine shop fluids. Be sure to use a facility like AIP who machines polymers and only polymers.

Preventing Contamination

Contamination is a serious concern when machining polymer components for technically demanding industries such as aerospace and medical. To ensure the highest level of sanitation down to the sub-molecular level, AIP Precision Machining designs, heat-treats and machines only plastics, with any sub-manufactured metalwork processed outside our facility.

Common Thermoplastic Materials in Aerospace & Defense

December 20, 2017

With over two decades of experience machining precision plastic and composite parts for the Aerospace & Defense industry, AIP Precision Machining knows that weight and strength are critical for your flight-ready hardware. That’s why we’ve carefully selected, machined and tested all our thermoplastic materials to various aerospace and defense industry standards. Our lightweight polymers and composites have stable chemical and corrosion resistance, as well as improved strength to weight ratios when compared to exotic alloys and non-ferrous metals. AIP’s polymer and composite materials maintain their properties even at high temperatures.

Here are some specific examples of thermoplastic materials commonly used in the Aerospace & Defense industry.

ULTEM – PEI

ULTEM has one of the highest dielectric strengths of any thermoplastic material. This enables ULTEM to work very efficiently as an electrical insulator. Being resistant to both hot water and steam, ULTEM can withstand repeated cycles in a steam autoclave and operate in high service temperature environments (340F or 170C). ULTEM also has one of the lowest rates of thermal conductivity among thermoplastics, allowing machined ULTEM parts to act as thermal insulators. ULTEM is FDA and NSF approved for both food and medical contact, making it an excellent choice for aircraft galley equipment such as ovens, microwaves and hot or cold beverage dispensing systems. Finally, its UL94 V-O flame rating with very low smoke output makes this material ideal for aircraft interior components.

CELAZOLE – PBI

CELAZOLE provides the highest mechanical properties of any thermoplastic above 400F (204C) and offers a continuous use operating temperature of 750F (399C). This impressive lightweight material has outstanding high-temperature mechanical properties for use in aircraft engines and other HOT section areas. These properties include good fatigue resistance, compressive strength, wear resistance and electrical insulation. After being submerged in hydraulic fluid at 200°F for thirty days, CELAZOLE retains 100% tensile strength.

RYTON – PPS

RYTON’s inherent fire retardancy, thermal stability, and corrosion resistance make it perfectly suited for aerospace applications, while its dimensional stability means even the most intricate parts can be manufactured from RYTON with very tight tolerances. RYTON is typically used for injection molded parts; however, there is limited availability of extruded rod and plate for machining.

VESPEL or DURATRON – PI

Like RYTON, VESPEL is dimensionally stable and has fantastic temperature resistance. It can operate uninterrupted from cryogenic temperatures to 550°F, with intermittent to 900°F. Thanks to its high wear and friction resistance, VESPEL performs with excellence and longevity in severe aerospace environments. VESPEL is a trademark material of DuPont and can be provided in direct formed blanks or finished parts directly from DuPont. AIP has provided precision machined components from DuPont manufactured rod and plate stock. You can typically find VESPEL used in high temperature and high-speed bearing and wear applications, such as stator bushings.

TORLON or DURATRON – PAI

DURATRON PAI’s extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire service range. PAI is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C). DURATRON PAI stock shapes are post-cured using procedures developed jointly by BP Amoco under the TORLON trade name and Quadrant under the DURATRON trade name. PAI components fabricated from extruded shapes that require optimization of chemical resistance and/or wear performance often receive a post-curing cycle. You can find TORLON parts in structural, wear and electrical aerospace applications.

TECHTRON – PPS

TECHTRON has essentially zero moisture absorption, which allows products manufactured from this material to maintain extreme dimensional and density stability. PPS is highly chemical resistant and can operate while submerged in harsh chemicals. Additionally, TECHTRON is inherently flame retardant and can be easily machined to close tolerances. PPS has a broader resistance to chemicals than most high-performing plastics, as well. TECHTRON can work well as an alternative to PEEK at lower temperatures for this reason.

RADEL – PPSU

With high heat and high impact performance, RADEL delivers better impact resistance and chemical resistance than other sulfone-based polymers, such as PSU and PEI. Its toughness and long-term hydrolytic stability mean it performs well even under autoclave pressure. Importantly, RADEL R5500 meets the stringent aircraft flammability requirements of 14CFR Part 25. These allow the aircraft design engineer to provide lightweight, safe and aesthetically pleasing precision components for various aircraft interior layouts. RADEL can also be polished to a mirror finish and is FDA and NSF approved for food and beverage contact.

KEL – F

Kel-F is a winning combination of physical and mechanical properties, non-flammability, chemical resistance, near-zero moisture absorption and of course outstanding electrical properties. This stands out from other thermoplastic fluoropolymers, as only Kel-F has these characteristics in a useful temperature range of -400°F to +400°F. In addition, it has very low outgassing and offers extreme transmissivity for radar and microwave applications. Many aircraft and ground-based random applications use Kel-F.

PEEK

PEEK can be used continuously in temperatures of 480°F (250°C) and in hot water or steam without permanent loss of physical properties. For hostile environments, PEEK is a high strength alternative to fluoropolymers. PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame. These aren’t the only reasons that PEEK is an increasingly popular choice for metal replacement in aerospace, however. Many manufacturers prefer PEEK for its lightweight nature, mechanical strength, creep and fatigue resistance, as well as its ease of processing. These and other exceptional physical and thermal characteristics make PEEK a versatile thermoplastic polymer for many aerospace applications. AIP has provided flight control, fuel system, interior, engine and aerodynamic-related PEEK components for various aircraft OEM and MRO providers worldwide.

KYNAR – PVDF

Another example of thermoplastic materials used in aerospace and defense is KYNAR, or PVDF. This polymer has impressive chemical resistance at ambient and elevated temperatures, as well as good thermomechanical and tensile strength. KYNAR is extremely durable due to its weather-ability and toughness even in the most severe environments. In addition to being flame-resistant, KYNAR is easy to machine, too. You can typically find KYNAR components in pipe fitting and various fuel or other fluid related precision manifolds or connectors.

Top 5 Things to Look for When Choosing an Aerospace Plastics Manufacturer

December 18, 2017

When looking to design a custom critical component for the aerospace industry, finding the right plastics manufacturer is just as important as deciding what resin works best for your project’s needs. The use of high performing plastics and thermoplastics such as ULTEM, TORLON, PEEK, and RADEL has quadrupled in aerospace design over the last 45 years thanks to their unique dynamic properties, and with them comes the need for precise machining and manufacturing.

Here are 5 considerations you should take into account before choosing your aerospace plastic parts manufacturing company:

Capabilities & Competency

Before hiring a plastics manufacturing company, first ensure that they have the plastic designing and production capabilities necessary to handle your aerospace project’s needs. The three main plastic production processes are 3D Printing, Injection Molding and Plastics Machining. Discovering which technology is most appropriate for your project is dependent on your project’s requirements… and the plastics manufacturer you decide on should be able to tell you the pros and cons of each technology.

The manufacturer you choose should also have the ability to navigate from your product’s initial vision through its production, addressing quality and customer care every step of the way. They should be able to competently handle the raw plastic materials of your choice as well, so that you receive the highest quality product in regards to cost, time, precision, efficiency, materials and more. Your project, regardless of specificity, can be machined into a highly precise and extremely resilient product.

Here at AIP Precision Machining, our decades of experience working with ULTEM, TORLON, PEEK, and RADEL high performing plastics ensures smooth navigation from your project’s start to finish.

Industry Standards

Product manufacturing companies must follow industry standards like International Organization for Standardization (ISO), Food and Drug Administration (FDA), International Traffic in Arms Regulation (ITAR) and more in order to ensure that their products hold up to specific requirements. Be wary of companies that have a default “Standard” methods—these are made-up specifications that do not follow recognized, insured specifications.

Take a careful look at a company’s ISO certifications. For instance, ISO 9001 is focused on meeting customer expectations, continually delivering customer satisfaction and it requires an organization to demonstrate constant improvement… If an organization doesn’t have this regulated license, you may want to ask them why.

Also, consider other notable ISO certifications like the AS9100 standard which is similar to the ISO 9001 standard, but with additional requirements for aerospace manufacturing that are tailored to a particular industry’s quality system expectations and regulatory requirements.

Here at AIP Precision Machining, not only are we registered to these standards, but we are registered to the most recent version of the ISO standards.

Additional Services

Plenty of plastic manufacturing firms offer consulting services as well as developmental processes. Going with a plastic product manufacturing company that has manufacturing conceptualization engineers can help in the long run if your project requires any design modifications. Engineering support also ensures efficiency through every step of your project’s progression.

Some plastics manufacturers also offer quality assurance measures. Not every company guarantees that their end products will hold up to your specifications but the firms that do will additionally offer services focused on comprehensive product design, development, patent registration guidance and prototype creation.

Here at AIP Precision Machining, we’re proud to offer a complete and effective quality assurance process that focuses on product quality, fast delivery, and cost-effective options.

Domestic vs. Overseas

If you decide to use an overseas factory, asking the right questions is critical to determine if they have the capabilities, credentials, and experience to become your trusted partner. It can often be difficult to find a reliable company that delivers high quality work. Some ways to find the best plastic manufacturer overseas is by asking for referrals, actually flying to their location, and asking a lot of questions and paying close attention to their responses. Many overseas factories will usually have a U.S.-based agent to represent them. If you find a company that seems like a good fit, ask to contact their domestic agent.

Domestic manufacturers, meanwhile, greatly reduce delivery times and shipping expenses; one who is in your same time zone allows for easy communication and improved customer services. There’s also the advantage that U.S. manufacturers have higher quality and labor standards, greater payment security, and high intellectual property right protection.

AIP Precision Machining is headquartered in Daytona Beach, Florida with an additional sales office in southern California. We provide an “open door” policy to our facility for potential and existing clients.

Experience & Expertise

Checking the track record of a company is important to get a clear outline of their performance, customer satisfaction, and overall product deliverability. Ask about their work history to see their range of experience and their level of expertise with aerospace projects similar to yours.

For instance, we at AIP Precision Machining have worked with leading aerospace and defense engineers and contractors such as Lockheed Martin, BAE Systems, and GE Aviation. With our 35+ years of polymer machining experience, we’re ready to take on the most stringent challenge to meet your needs.
