PPO Mold Material Selection
Fenómeno del problema
After using ordinary steel for PPO molds, early wear and corrosion appear, cavity surface quality deteriorates rapidly, and product appearance declines accordingly.
Análisis de la causa
PPO's high process temperature requires mold materials with heat and wear resistance; the potential corrosiveness of the melt accelerates the deterioration of ordinary steel; thermal fatigue damage accumulates under high-temperature working conditions.
Solución
①Select high-quality tool steel or high thermal conductivity aluminum for the mold; ②cavity surface strengthening treatment; ③regular cavity inspection and maintenance; ④include mold life and maintenance costs in the evaluation.
Conclusión clave
PPO mold material is a long-term quality investment; the cost of high-quality tool steel can be amortized through service life; a maintenance plan extends the effective mold cycle.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
