Improper Screw Speed of PBT '2079851475616104452 Machine
문제 현상
An excessively high screw speed causes excessive shear heat and degradation, while an excessively low speed causes insufficient plasticization and uneven product quality.
원인 분석
The screw speed is not optimized according to the characteristics of PBT and the glass fiber content; the general setting is not suitable.
해결 방법
For PBT reinforced material, the recommended screw speed is 50-80rpm; reduce the back pressure to reduce shear heat; monitor the melt temperature.
핵심 요약
The PBT screw speed needs to balance plasticization and shear heat.
