Product Description:

High-precision tooling solution for large-scale automotive interior components, specifically dashboards and center consoles. Engineered with sequential valve gating to eliminate visible weld lines and optimize resin flow across expansive surface areas. Features a robust hydraulic slide mechanism for complex undercut management and integrated cooling channels for minimized cycle times. Built to withstand high-volume production demands while maintaining the stringent dimensional stability and aesthetic integrity required by global Tier-1 automotive standards.



Product Overview

This is an extra-large, high-complexity injection mold designed for the most demanding automotive interior applications. Engineered to produce large-format structural components—such as dashboard carriers, center console frames, or integrated door modules—this tooling represents the pinnacle of heavy-duty mold engineering.
At JST Mold, we have the infrastructure and expertise to handle "Big Mold" projects. This tooling features a massive, reinforced mold base and a sophisticated network of inserts and lifters, ensuring that even the most complex 3D geometries are molded with repeatable micron-level accuracy.



Key Features

  • Heavy-Duty Large-Format Design: Engineered for use in 1000-ton to 3000-ton injection molding machines, featuring a robust structure that maintains alignment under extreme clamping pressures.
  • Complex 3D Surface Engineering: Expertly managed parting surfaces and deep-draw cavities ensure the structural integrity of large automotive parts while maintaining consistent wall thickness.
  • Advanced Core-Pulling & Lifter Systems: Equipped with multiple precision-synchronized lifters and sliders to handle the numerous undercuts and attachment points typical of automotive interior assemblies.
  • Optimized Thermal Cooling Layout: Features a high-performance, multi-zone cooling system designed to manage heat dissipation across the entire large surface area, significantly reducing cycle times and preventing part warpage.
  • Precision Insert Technology: Utilizes high-precision modular inserts in critical areas, allowing for superior venting, easier maintenance, and the flexibility to accommodate minor design revisions.
