PPS mold heating system design
Fenómeno del problema
PPS requires 140°C mold temperature, which is difficult to achieve with ordinary mold heating systems.
Análisis de la causa
The mold needs uniform heating to 140-150°C across all areas to prevent cold spots from causing poor local crystallization.
Solución
Design electric heating tube heating system + insulation board; zone temperature control and use infrared to detect temperature distribution.
Conclusión clave
PPS mold high-temperature uniformity is the foundation of product consistency.
