PI (VESPEL) polyimide is one of the most high-end engineering plastics, with excellent properties, such as high-temperature resistance, wear resistance, corrosion resistance, radioactivity resistance, and low friction coefficient. It also has mechanical properties, good fatigue resistance, and good self-lubrication; the tensile strength of phenylene polyimide film can reach 170 MPa, and that of biphenyl type can reach 400 MPa. Moreover, It has excellent heat resistance, can be used for a long time at -260 (no brittleness) ~ 330℃, and the thermal deformation temperature is as high as 343℃.
It has been widely used in aviation, aerospace, microelectronics, nano, liquid crystal, separation film, laser, and other fields. Recently, all countries keep researching, developing, and utilizing polyimide. 4-axis and 5-axis customized PI precision components will be one of the most promising CNC machining engineering plastics parts in the 21st century.
At present, PlasticPartsCustom continues to increase the application of PI precision parts in various industries. We’d like to supply customized PI precision CNC service for you.
In PlasticPartsCustom, all our test and measure equipment is imported. Each of our 5 axis CNC equipment is qualified with imported Reinshaw measuring systems. When machining, our system finds improper processes or any mistakes to prevent scrapped parts and save lots of time.
The measure equipment room is kept at a constant temperature and humidity (22°C-24°C, 45%-65% humidity) to make sure all the measurements are precise.
The following is the details of the principal measurement instruments.
