The Relationship Between CNC Machining and Injection Mold: Synergy in Precision Manufacturing

1. Injection Mold Manufacturing Process and the Application of CNC Machining

The production of Injection mold is a highly precise process involving multiple manufacturing techniques, where CNC machining plays a vital role. Below is the injection moulding process step by step, along with the applications of CNC machining:

(1) Mold Design & 3D Modeling

• Mold structure design directly impacts final product quality and production efficiency

• CAD/CAM software optimizes parting surfaces, cooling systems, ejector pin layouts, etc.

(2) Mold Base Processing (CNC Milling & Turning)

• Mold bases typically use pre-hardened steel (P20, 718) or tool steel (H13)

• CNC machining (especially cnc milling machine aluminum and cnc turning) processes core components like cavities, cores, and sliders

• High precision CNC machining supplier ensures dimensional tolerances within ±0.005mm

(3) Electrode Processing (EDM)

• Complex surfaces or deep grooves require copper electrodes for EDM machining

• CNC machining manufacturer in china typically uses cnc milling for precise electrode shaping

(4) Wire Cutting

• Processes precision inserts, special-shaped holes, and ejector pin holes

• China CNC machining parts factory employs slow wire cutting with ±0.005mm accuracy

(5) Precision Grinding

• Critical surfaces like mating planes and guide pin holes require grinding

• CNC machining company combines CNC grinding for ultra-precision finishing

(6) Polishing & Surface Treatment

• Mold surface finish directly affects product appearance

• Manual polishing or CNC machining-assisted methods (like mirror EDM)

(7) Trial Molding & Adjustment

• Verifies mold performance through test shots

• Uses CNC machining for final adjustments when needed

This process demonstrates how Injection mold manufacturing relies on CNC machining at nearly every stage. As a CNC machining manufacturer, JSJM provides complete mold manufacturing services meeting high standards for Auto parts mold manufacturing and medical device injection moulding.

2. How CNC Machining Optimizes Injection Mold Production?

(1) High-Precision Mold Components

• CNC machining produces cores, cavities, and sliders with extreme accuracy

• Custom precision parts like inserts and guide pins from CNC turning factory

(2) Rapid Prototyping & Small-Batch Testing

• CNC machining fast delivery enables quick prototypes for design validation

• Critical for CNC machining for automotive industry and CNC machining for medical devices

(3) Complex Geometry Capabilities

• 5-axis CNC machining handles freeform surfaces for plastic injection molds factory

• Essential for chip test fixtures for semiconductor industry and spare parts for lithography machines

(4) Mold Maintenance & Repair

• CNC machining supplier provides precision repair services to extend mold life
