Product Overview
This is a premium large-format plastic injection mold specifically engineered for the high-volume production of automotive interior components. Designed to handle long and complex parts such as door panel inserts, pillar trims, or internal structural frames, this tooling represents the peak of heavy-duty precision engineering.
At JST Mold, we specialize in "Big Mold" projects that require both massive scale and micron-level accuracy. This mold is built to provide exceptional dimensional stability, ensuring that large plastic parts maintain their shape and fit perfectly into complex vehicle assemblies cycle after cycle.
Key Features
- Large-Format Engineering: Specifically designed for large-tonnage injection molding machines, featuring a reinforced mold base to ensure rigidity and alignment under extreme pressure.
- Precision Internal Geometry: The mold incorporates numerous precision-ground inserts to form complex structural ribs and mounting points, ensuring the final part has high mechanical strength.
- Superior Surface Preparation: The cavity surfaces are finished to a high technical standard, ready for "Class A" texturing or high-quality graining as per automotive OEM specifications.
- Optimized Cooling Layout: Equipped with an advanced, multi-zone water cooling system to manage the thermal profile of large parts, effectively reducing cycle times and preventing warpage.
- High-Grade Hardened Steel: Manufactured using premium tool steels like 1.2738H or 718H, offering the ideal balance of toughness and wear resistance for high-speed production environments.
