PPO Compression Molding Temperature Procedure
Sorun Belirtisi
【Problem Phenomenon】PPO compression molded products have unstable performance, and laminates delaminate
Neden Analizi
PPO compression molding procedure: raise mold temperature to 250℃ and hold for 5min, pressure 6MPa, continuously heat up to 300℃ and hold for 1h, naturally cool to 180℃ then pass cold water to room temperature for demolding; the temperature and pressure rhythm must be strictly executed
Çözüm
Execute according to the 250℃→300℃→180℃ temperature rhythm and 6MPa pressure; adjust holding time in proportion to thickness; laminate resin content 35%±5% dried at 70-110℃
Temel Çıkarım
PPO compression molding follows the 250/300/180℃ three-stage rhythm, no hurry allowed; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
