Mold Design for Engineering Plastics: Practical Considerations for PA, PBT, and PPS
12 December. 2025
Mold Design for Engineering Plastics: Practical Considerations for PA, PBT, and PPS
The foremost consideration is precise and often elevated mold temperature control. Materials like PPS and certain PA grades require high mold temperatures (often 130°C-160°C) to ensure proper crystallization and prevent premature freezing, which leads to poor surface finish, high stress, and short shots. This demands robust mold heating systems,
