How about the processing performance of PEEK material? What should be paid attention to?

PEEK (polyether ether ketone) resin is a special engineering plastic with excellent performance. Compared with other special engineering plastics, it has many significant advantages, such as high temperature resistance, excellent mechanical properties, good self-lubrication, chemical resistance, flame retardancy, Peel resistance, radiation resistance, stable insulation, hydrolysis resistance and easy processing.

If the PEEK processing process does not handle the internal stress problem, it will be deformed. It has a stress release process, so you need to be careful when processing. Generally, if the wall thickness of the product is not very thin, use coolant during processing to feed the knife. If the magnification of the plate is lowered, it is not easy to deform unless the wall of the product is very thin. But if it is processed after injection of power, it will be deformed, and it will have a stress relief. It can be considered from the following points:

1. The internal stress of the material is not completely removed;

2. Large cutting volume during processing, or no cooling water added

3. The amount of material removed on one side is too large

4. Material tooling is unstable

5. Clamping deformation
