PSU Mold Venting Design
문제 현상
Poor PSU mold venting causes repeated trapped-air defects; vent grooves need frequent cleaning; the design is inherently insufficient.
원인 분석
PSU high-viscosity melt filling has high venting requirements; vent groove size and position are improperly designed; low-molecular volatiles clog; maintenance is difficult.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based solely on experience
해결 방법
①Design vent grooves for high-viscosity materials; ②Position covering weld areas; ③Structure convenient for cleaning and maintenance; ④Regular maintenance plan.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
핵심 요약
PSU venting design must consider maintainability in advance; high-viscosity materials have higher venting requirements; maintainable design reduces long-term cost.; After confirming effectiveness, solidify the parameters and practices into the work instructions to prevent recurrence
