PEI is a high-performance plastic. In recent years, in the electrical and electronic industries, PEI precision-machined parts have been used to replace metal to make optical fibre connectors to optimize the component structure, simplify its manufacturing and assembly steps, and maintain more precise dimensions. Because polyetherimide (PEI) material has excellent performance, PEI plastic parts machining has been widely used. Uses include connectors with high strength and stable dimensions, ordinary and micro relay housings, flexible circuits, reflectors, circuit boards, coils, and high-precision dense optical fibre components.
Here are some examples of PEEK machining parts applications:
1. The lathe milling products are mainly used in the automotive industry because PEEK has uniquely high strength and toughness. CNC processed PEEK parts can better meet the performance requirements.
2. It is used for additional testing of high-tech 3D glasses.
3. PlasticPartsCustom provides PEEK processing parts to the mechanical instrumentation industry. At present, our production of PEEK high-precision processing parts have been widely recognized and used by customers.
4. The semiconductor industry has an extensive range of applications in PEEK precision processing parts. Sometimes, the component is only 1mm thick. PlasticPartsCustom constantly improves its 4-axis and 5-axis machining technology, so even if some accessories are extremely thin, PEEK processing products still have good toughness and strength. The components are not easy to break as the flatness tolerance of the entire product can be maintained at ./- 0.03mm.
To date, our PEEK parts have been exported to many countries in Europe and the United States for medical, aerospace and military applications. All CNC machining parts are carefully inspected and reported using the appropriate measuring equipment before export.
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.
