PA66 release agent residue
Problem Phenomenon
After using release agent, PA66 products have poor coating and increased silver streaks
Cause Analysis
Excess release agent accumulates on the mold surface, the next shot is entrapped by the melt forming silver streaks, and the residual film blocks coating adhesion; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
Solution
Spray release agent in small amounts multiple times; regularly clean the mold surface; try not to use release agent for coated parts and switch to process means for demolding; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
Key Takeaway
Release agent is a double-edged sword, coated parts should prioritize process demolding; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
