PEEK Extrusion High Torque and Melt Temperature
문제 현상
【Problem Phenomenon】The PEEK extruder torque exceeds the limit and alarms, and the motor load is too large, forcing production reduction
원인 분석
PEEK melt viscosity is high; when the melt temperature is below 365℃, the viscosity rises sharply and the torque exceeds the limit; screw wear and screen blockage also push up the torque; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
Keep the melt temperature above 365℃ and calibrate by actual measurement; regularly check screw clearance and screen pressure differential; troubleshoot high torque alarms in the order of temperature-wear-blockage; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
For extrusion high torque, first check the 365℃ lower limit of melt temperature, then check wear and screen blockage; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future
