What is Thermal Expansion (and Contraction)?   Thermal expansion or contraction occurs when a material is exposed to temperature change and thus leads to change in all dimensions, as well as other physical properties.  While this effect is most noticeable in gasses and liquids, it is also notable in solids.  Softer materials such as unreinforced polymers experience greater levels of dimensional change per each degree change in temperature.   When...

3 Tips from the Plastics Machining Pros on choosing the most suitable material for your machined polymer components   CNC machining produces high-end, mission critical products for many markets and industries. It allows for tight tolerances on part dimensions and complex designs. However, before the machining can happen, the design must be completely planned out with your manufacturer. In order to get the best outcome for the design, you must... Read More

An Informational Brief on Polymer Machining   One of the high-performance polymers we precision machine is ECTFE (Ethylene Chlorotrifluoroethylene).  It is marketed under the branded name of Halar® ECTFE by Solvay Specialty Polymers.  This material was developed to provide chemical resistance in heavy duty corrosion applications, such as acid handling, mining applications and class 8 hazardous goods transportation.   AIP has over 37 years of experience machining complex components from...
