Frequently Asked Questions
PEEK, PPS, PEI, LCP, PTFE, polyimides — processing above 350°C, often exceeding 400°C.
Aerospace components, automotive engine parts, semiconductor equipment, medical sterilization devices, high-performance electrical connectors.
High-temp materials (maraging steel, cobalt/nickel superalloys), geometry minimizing residence time.
Accelerates thermal fatigue, oxidation, creep deformation; hardness drops at temperature; thermal cycling causes micro-cracking; dimensional changes affect precision.
Max processing temp, barrel thermal conductivity, coating stability at temperature, and performance vs. cost trade-off.
