Surface Coating Options for Our Mold:
- Nitriding (Salt Bath or Plasma)
Enhances surface hardness, wear resistance, and corrosion protection while maintaining dimensional stability under high-pressure cycles.
- Hard Chrome Plating
Provides superior corrosion resistance, reduced friction, and improved mold release performance for high-volume gasket production.
- PVD (Physical Vapor Deposition) Coating
Applies ultra-thin, durable coatings (e.g., CrN, TiN) to minimize sticking, reduce abrasive wear, and extend tool life in high-temperature molding environments.
- Shot Peening
Induces compressive surface stresses to mitigate crack propagation and improve fatigue resistance in high-stress mold components.
Production Process:
- Design & Engineering
– CAD-based 3D modeling for precise mold geometry.
– Finite Element Analysis (FEA) to simulate compression and stress distribution.
- Material Selection
– High-grade tool steel (e.g., H13, S7) for heat resistance and durability.
– Optional hardened coatings (e.g., nitriding) for extended tool life.
- CNC Machining
– Roughing and finishing via 5-axis CNC for critical cavity/core profiles.
– Tight tolerance control (±0.005 mm) for sealing surface accuracy.
- Heat Treatment
– Vacuum hardening and tempering to achieve HRC 48-52 hardness.
– Stress relief to minimize warpage during operation.
- Precision Surface Finishing
– EDM (Electrical Discharge Machining) for intricate details.
– Manual polishing or grinding to achieve Ra ≤0.4 μm surface finish.
- Assembly & Fitting
– Integration of ejector systems, alignment pins, and cooling channels.
– Dry-run testing to verify parting line consistency and ejection function.
- Trial & Validation
– Sample molding using production-grade rubber compounds.
– Dimensional checks (CMM) and pressure/leakage testing per ASTM standards.
- Surface Coating (Optional)
– Application of anti-adhesion coatings (e.g., PTFE) to reduce flash and sticking.
- Final QC & Documentation
– Full inspection report including hardness, flatness, and cavity dimensions.
– Provision of 2D drawings, material certs, and maintenance guidelines.
- Packaging & Delivery
– Shock-proof crating with moisture-resistant packaging.
– FOB or DDP logistics support based on client requirements.
