P20 Steel Plastic Injection Molds 300K Shots Cold Runner Molds For Automotive Parts

Cold runner injection molds utilize a traditional runner structure, introducing molten plastic into the mold cavity through a gate. Their relatively simple structure and low production cost make them suitable for molding a variety of thermoplastic materials and are widely used.

1. Mold Design: CAD/CAE design based on product dimensions and plastic flowability
2. Material Preparation: Select P20 or 718H steel and pre-treat it
3. Processing and Manufacturing: Cavity and runner machining is performed using CNC and EDM
4. Heat Treatment: Improve mold wear resistance and hardness
5. Assembly and Commissioning: After assembly, test molds are performed and gate positions are optimized.

Widely used in the production of plastic parts for automotive parts, home appliance housings, and daily consumer goods.
