PEEK Injection Molding

The manufacturing process of PEEK injection molding parts is relatively complex and requires strict control of each link to ensure product quality.

Raw material preparation

 Use high-purity PEEK particles to ensure the stable performance of injection molding. The purity requirement is usually above 99.5%.

Mold design

The mold design of PEEK injection molding needs to take into account its poor fluidity and reasonably design the gate, runner and cooling system to ensure the dimensional accuracy and surface quality of the injection molding parts. The mold temperature is generally controlled at 120-150°C.

Injection molding machine selection

PEEK injection molding requires the use of a high-temperature injection molding machine, and the temperature and pressure control accuracy of the injection molding machine must be high to ensure the stability of the injection molding process. The injection molding temperature is generally between 350-400°C and the pressure is 100-150 MPa.

Injection molding process parameter setting

PEEK injection molding process parameters include temperature, pressure, speed and cooling time, etc. They need to be optimized according to specific material and product requirements to ensure the performance and quality of injection molded parts. The cooling time is generally controlled at 20-40 seconds.

Post-processing

PEEK injection molded parts need post-processing, such as annealing and machining, to eliminate internal stress and improve dimensional accuracy and surface quality. The annealing temperature is generally 150-200°C and the time is 1-2 hours.
