PC injection pressure 100-150
문제 현상
【Problem Phenomenon】PC filling pressure insufficient causing short shots, overpressure causes internal stress and flash
원인 분석
PC has high viscosity requiring higher injection pressure 100-150MPa: thin-walled complex parts take the upper limit; excessive pressure introduces internal stress and flash；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
해결 방법
Set according to the 100-150MPa window; thin wall takes the upper limit; reduce pressure to reduce stress after filling is satisfied；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
PC injection 100-150MPa, high viscosity requires high pressure but prevent overpressure；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
