PCABS back pressure adjustment
문제 현상
PC/ABS back pressure too high, shear heat, reduce in 50psi steps, observe 10+ cycles.
원인 분석
PC/ABS back pressure too high, shear heat degrades heat-sensitive materials; reduce in 50psi steps; observe 10+ cycles per adjustment; heat silver streak troubleshooting; shear heat management.
해결 방법
①Reduce back pressure in 50psi steps; ②observe 10+ cycles; ③heat silver streak troubleshooting; ④shear heat management; ⑤melt temperature monitoring.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
The step adjustment and observation cycles of PCABS back pressure are fine craftsmanship; shear heat management protects the material; monitoring prevents degradation.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
