D2 Hardened Angle Pin Slide Mold Unit
- Material: D2 Cold Work Tool Steel
- Hardness: HRC 60–64 post hardening & ion nitriding
- Tolerance: ±0.001 mm for dovetail mating and forming surfaces
- Surface Finish: Ground, nitride wear-resistant finish
High-Precision Engineering
Integrated dovetail interlock structure ensures stable angular sliding force during undercut retraction, preventing tipping or offset under high injection pressure. Replaceable slide wear strips protect the main D2 base block from friction erosion, cutting long-term mold maintenance costs drastically. Standard base mounting holes fit universal mold frame layouts, speeding up mold assembly and trial adjustment periods. The one-piece angled forming tip creates sharp, precise internal undercut geometries without split insert flash lines.
Ultra-Wear Resistant D2 Tool Steel Construction
Constructed from premium D2 cold work tool steel, this slide unit excels in high-abrasion molding environments:
- Exceptional abrasion resistance for millions of cycles with glass/mineral-filled plastic raw materials
- High compressive hardness with minimal plastic deformation under sustained clamping loads
- Stable dimensional accuracy with low thermal expansion fluctuation during repeated mold heating/cooling cycles
- Strong edge retention for sharp angled forming tip profiles, resisting chipping and blunting Ideal for mass-volume automated cold injection molding production lines with abrasive resin formulations.
Modular Customizable Structure
Fully configurable design parameters to match molding demands:
- Custom slide angle, travel stroke and forming tip profile geometry
- Interchangeable dovetail wear strip thickness and slide width sizes
- Optional ion nitriding or TiN hard coating for sliding contact surfaces
- Single and paired synchronized slide layout customization
Key Features & Advantages
- Extreme Abrasion Durability: D2’s ultra-high hardness withstands abrasive filled plastics far longer than standard mold steels.
- Stable Angular Slide Motion: Dovetail interlock eliminates tilt and offset during core pulling under high injection pressure.
- Low Maintenance Modularity: Wear strips are independently replaceable without full slide unit disassembly.
- Flash-Free Forming: Monolithic angled forming tip removes split insert seams for clean undercut molded part surfaces.
