ASA Venting High-Speed Matching
Problem Phenomenon
ASA mold venting must be good, matched with high-speed injection, air trap and burnt prevention and control.
Cause Analysis
ASA venting must be good because high-speed injection is recommended; high-speed air trap burnt; vent groove design; position coverage; depth control; maintenance cleaning.; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solution
①Sufficient vent grooves; ②position covering converging areas; ③depth adapted to high speed; ④regular cleaning; ⑤air trap monitoring.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA vent design is the prerequisite for high-speed process; equal emphasis on position and depth; maintenance ensures long-term effectiveness.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
