EVA '2079851475616104452 mold sticking
Sorun Belirtisi
The product sticks to the mold and demolding is difficult.
Neden Analizi
EVA melt has strong tack and easily adheres to the mold surface; high mold temperature or insufficient release agent aggravates mold sticking.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Çözüm
①Use a release agent; ②appropriately lower the mold temperature; ③polish the mold surface; ④optimize the ejection design.; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
EVA tack is a material characteristic; the release agent and mold surface condition are the main countermeasures.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
