The standard injection mold development process consists of 7 major stages, and it takes an average of 45-60 days from design to mass production.

1. Product Analysis (3-5 days)

Conduct DFM (Design for Manufacturability) verification

Determine parting lines and draft angles (typically ≥1°)

Perform Moldflow simulation to optimize gate locations

2. Mold Design (7-10 days)

Mold base selection (standard mold base)

Cavity layout

Design cooling channels (following 3D conformal principles)

3. Precision Machining (15-20 days)

Cavity machining: CNC roughing (leaving 0.3mm allowance) / EDM finishing

Key components: Ejector pinhole tolerance controlled to H7 grade

Surface treatment: Mirror polishing to VDI18 standard

4. Mold Testing and Validation (5-7 days)

Initial trial (T0): Check basic molding results

Engineering adjustments: Optimize packing time (typically 0.5-5s) and cooling time (accounting for 30-60% of the cycle)
