Mold temperature differences in different areas affect product quality

Fenómeno do problema
Mold temperature differences in different areas affect product quality
Análise das causas
Temperature difference between cavity and core too large, product warps Mold temperature at the gate area too high, insufficient cooling at the gate area Mold temperature differences between thick and thin areas of the product need targeted settings Multi-cavity molds have independent temperature control for each cavity but the settings are not unified Cellulose acetate butyrate crystallinity requires a higher mold temperature to ensure complete crystallization (PA type)
Solução
Reasonably set the cavity-core temperature difference (core 5-10°C higher) Strengthen cooling in the gate area Set mold temperature separately for thick and thin areas Unify multi-cavity mold temperature settings Set PA type mold temperature to the higher value of 40-80°C to promote crystallization
Conclusão principal
Mold temperature gradient needs to be set according to area and material characteristics
