PVD Multi-Arc Ion Plating System for Automotive Molds
In the high-stakes world of automotive manufacturing, mold performance directly impacts part quality, cycle time, and profitability. Our advanced PVD Multi-Arc Ion Plating System delivers ultra-hard, low-friction coatings specifically engineered for the unique demands of automotive molds — from large-scale body panel dies to high-precision injection molds.
Whether you're molding PP, ABS, or stamping high-strength steel, this system ensures your molds release easier, wear less, and last significantly longer.
Why Automotive Molds Need PVD Multi-Arc Technology
Automotive molds face extreme conditions: abrasive fillers in plastics, adhesive wear in stamping, and corrosion from coolants. Traditional surface treatments (nitriding, chrome plating) often fall short.
Our PVD multi-arc system solves these challenges by depositing dense, metallurgically bonded ceramic coatings such as TiN, CrN, TiAlN, AlCrN films directly onto mold surfaces — at temperatures low enough to preserve critical core hardness.
Features & Advantages
| Feature | Benefit for Automotive Molds |
|---|---|
| High ionization rate (>90%) | Exceptional coating adhesion — no peeling or flaking under high injection or stamping pressures. |
| Low deposition temperature (200–500°C) | Safe for pre-hardened mold steels; no distortion, no re-quenching required. |
| Multi-arc source array (6–24 pcs) | Uniform coating coverage on complex 3D mold cavities, ribs, and cooling channels. |
| Advanced bias control | Tailored coating structure — from smooth low-friction surfaces to nano-multilayer hardness. |
| Vacuum-sealed process | Zero hydrogen embrittlement; fully complies with automotive industry environmental standards. |
Coating Solutions for Common Automotive Mold Challenges
| Mold Type | Coating Recommendation | Performance Gain |
|---|---|---|
| Injection molds (bumpers, dashboards) | CrN or AlCrN | Anti-sticking, easy part release, reduced cycle time by 15–20% |
| Stamping & drawing dies | TiAlN or AlTiN | High-temperature hardness (up to 1100°C), 3–5x longer edge life |
| Trim & shearing punches | TiCN | Low friction coefficient (0.25–0.35), less galling on high-strength steel |
| Aluminum die-casting molds | AlCrN + top layer | Excellent molten metal corrosion resistance, reduces soldering |
| Slides & lifters | DLC (diamond-like carbon) | Nearly frictionless, eliminates lubricant staining on visible plastic parts |
