Product Description
Cold Runner Injection Mold 300K Shots P20 Steel For Automotive Parts
Cost Effective Simple Structure Versatile Applications
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.
Process Flow
- Mold Design: CAD/CAE design based on product dimensions and plastic flowability
- Material Preparation: Select P20 or 718H steel and pre-treat it
- Processing and Manufacturing: Cavity and runner machining is performed using CNC and EDM
