PEEK (polyether ether ketone) special engineering plastic processing has a certain particularity and complexity, the following are some key points about PEEK processing:

1. Material preparation

PEEK materials need to be dried before processing, usually at a temperature of about 150°C for several hours to remove water from the material and prevent problems such as hydrolysis during processing.

2. Processing method

- Injection molding: often used to manufacture PEEK products with complex shapes and high dimensional accuracy requirements. Need to pay attention to control injection temperature, pressure and speed parameters.

- Extrusion molding: can be used to produce PEEK pipe, bar and other profiles.

- Machining: including turning, milling, drilling, etc., suitable for secondary processing and customized processing of PEEK.

3. Processing temperature

The injection molding temperature is generally between 380-400 °C, and the extrusion temperature is also high, usually around 360-390 °C.

4. Tool selection

- When machining, carbide tools or diamond tools should be selected to ensure good cutting performance and surface quality.

5. Cooling and lubrication

- Effective cooling and lubrication are required during machining to reduce friction heat and tool wear.

6. Process control

- Strictly control the speed, feed and other parameters in the processing process to avoid material degradation or product defects caused by improper processing.

7. Post-processing

- Some PEEK products may need to be annealed to eliminate internal stress and improve dimensional stability and mechanical properties.

In short, the processing of PEEK special engineering plastics requires professional equipment, technology and experience to ensure that the quality and performance of the products meet the application requirements.
