PARA High Injection Speed
Problem Phenomenon
PARA injection speed is set improperly; balancing high-speed requirements against jetting and burnt risks.
Cause Analysis
PARA injection speed recommends high speed of 0.5~2.5 seconds; high-speed filling obtains good surface and meld lines; but too fast causes jetting and burnt; multi-stage injection balancing.
Solution
①Set injection speed at high speed of 0.5~2.5 seconds; ②Multi-stage injection gate area control; ③Jetting and burnt monitoring; ④Speed optimization verification.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PARA high-speed injection is the official recommendation; 0.5~2.5 seconds is the quantitative window; multi-stage control prevents side effects.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
