Stainless Steel High Hardness Core Insert Mould Parts
Precision mold core inserts designed for plastic injection tooling applications, manufactured with high hardness materials and exacting tolerances for optimal performance.
Mold Core Insert Manufacturing Guidelines
Our manufacturing process ensures precise dimensional tolerances for perfect fitment in insert plates and mold cavities/cores, saving significant time during mold assembly.
- Corner Radius Processing: Manual milling creates 0.2mm steps at corners, eliminating post-hardening grinding requirements
- Dimensional Tolerance: External dimensions maintained at +0/-0.015mm for smooth pocket fitting
- Sprue Bushing Fit: Hole tolerance maintained at H7 (0/+0.015mm)
- Thread Depth Standard: 1.5-2 times thread diameter (12-16mm for M8 screws)
- Ejector Pin Guidance: 15-20mm guidance length ensures smooth ejection and extended service life
