Automotive Interior Plastic Components Injection Mold
The injection mold for automotive interior plastic components is a comprehensive tooling solution designed for manufacturing a wide range of interior parts including trim panels, bezels, housings, brackets, and functional components. This mold system integrates advanced features such as hot runner manifolds, guided ejection, precision slide mechanisms, and conformal cooling circuits. The tooling accommodates multiple material grades including PC, ABS, PC/ABS, PP, POM, and PA6. Steel selection includes P20 and H13 grades with surface treatments including nitriding and PVD coatings. The design incorporates cavity identification, wear-resistant inserts, and thermal monitoring systems to ensure consistent part quality across extended production runs. Ejection strategies combine ejector pins, air poppets, and stripper plates for damage-free demolding of complex geometries.
Core advantages
- Versatile material compatibility (PC, ABS, PC/ABS, PP, POM, PA6)
- Hot runner system with individual zone temperature control
- Guided ejection with wear-resistant bushings
- Conformal cooling with thermal monitoring
- Interchangeable inserts for design flexibility
- PVD coating (TiAlN) on wear-prone surfaces
- Single to 16-cavity configurations available

Processing considerations
- Mold temperature: 40–80°C depending on material grade
- Injection profile: decoupled filling with multi-stage control
- Pack pressure: 40–70% of injection pressure, hold time 2–8 sec
- Venting depth: 0.010–0.030 mm based on material viscosity
- Shrinkage allowance: 0.3–1.8% based on material selection
- Gate design: fan, edge, or pinpoint based on geometry
- Cooling: conformal circuits with 6–12 mm diameter channels
