Sorun ve Çözüme Geri Dön
Molds & Tooling 6 görüntüleme

Product incomplete crystallization, poor performance

Sorun Belirtisi
The product appears amber translucent (amorphous), and mechanical strength and chemical resistance are far lower than expected
Neden Analizi
Mold temperature <180°C causes the skin layer to quench forming amorphous structure; cooling rate in the cavity too fast, molecular chains have no time to arrange orderly
Çözüm
Strictly maintain the mold temperature at 180-200°C using an oil temperature control system; product post-crystallization heat treatment at 200°C/2h to promote full crystallization (up to 30-40% crystallinity)
Temel Çıkarım
PEEK crystallinity needs to reach more than 30% to fully reflect its high performance
