PARA Demolding Sticking
Problem Phenomenon
PARA products or sprues stick to the mold; excessive holding, insufficient draft angle, improper mold temperature.
Cause Analysis
Holding time too long or pressure too high; insufficient mold cavity draft angle; improper mold temperature; thermal matching between product and mold.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based only on experience
Solution
①Reduce holding time and pressure; ②Increase draft angle; ③Optimize mold temperature; ④Demolding system check.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PARA sticking treatment covers the three elements of holding, draft angle and temperature; excessive holding is a common inducement; systematic design prevents recurrence.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
