Polyetheretherketone (PEEK) Manufacturing & Tooling Guide
PEEK is processed at extreme temperatures near 400°C. Inadequate heating controls will freeze the melt instantly, leading to incomplete crystallization, internal stresses, and mechanical weakness:
- 予備乾燥: PEEK must be thoroughly dried to prevent hydrolytic splay. We dry the raw polymer in desiccant hopper dryers at 150°C (302°F) for 3–4 hours, keeping internal moisture levels strictly below 0.02%.
- Extreme Melt Temperature: Melting requires specialized machines with ceramic heater bands. Processing temperatures are strictly managed between 360°C and 400°C (680°F to 752°F).
- Critical Mold Temperature: To secure proper semi-crystalline alignment (which gives PEEK its beige opaque look and strength), mold temperatures must be continuously maintained at 160°C–200°C (320°F to 392°F) using pressurized oil-heating controllers. Cold molds cause the material to freeze amorphous, turning translucent brown and structurally weak.
- Specialized Tool Steel: Due to extreme injection pressures and thermal loads, Jucheng’s tooling division uses hardened tool steel (H13 or S136) designed with robust draft angles (minimum 1.5° to 2.0°) and reinforced ejector layouts.
