PEEK加工

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

PEEK machining process will deform if the internal stress is not properly handled. It has a process of stress release, so it needs to be carefully operated during processing. Generally, if the wall thickness of the product is not very thin, the coolant is used during processing. If the rate of feed plate is low, it is not easy to be deformed, unless the wall of the product is very thin. But if it is injected right after plastic processing will also be deformed, it has a stress release. Please consider the following points:

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

2. Large cutting amount during processing, or no cooling water is added;

3. Too much unilateral material removal;

4. Material tooling is not stable;

5. Clamping deformation.
