Engineering the Future of High-Volume Automotive Manufacturing


This sophisticated injection mold is a prime example of JST Mold’s ability to integrate complex mechanical systems into a single, high-performance production unit. Engineered for large-format automotive structural and interior parts, this tooling features a massive reinforced mold base and a fully integrated hydraulic/pneumatic core-pulling system. Every aspect of this mold is optimized for 24/7 automated production, ensuring that even the most complex parts with deep undercuts and intricate attachment points are produced with repeatable, micron-level accuracy.

Advanced Technical Systems & Integrated Solutions

  • Automated Multi-Directional Core Pulling:The integrated red hydraulic manifolds and precision-synchronized cylinders manage complex side-actions. This allows for the molding of intricate lateral features and internal clips in a single cycle, eliminating secondary assembly steps and maximizing production efficiency.
  • High-Performance Multi-Zone Hot Runner System:Equipped with a premium hot runner manifold to ensure balanced material flow and pressure across large surface areas. This results in superior part density, zero material waste, and exceptional surface consistency—critical for Tier-1 automotive quality standards.
  • Heavy-Duty Precision Alignment:Four oversized, hardened leader pillars and a precision-ground mold base ensure perfect registration between the core and cavity halves. This robust construction maintains zero-tolerance closure even under extreme clamping forces, preventing flash and extending tool life.
  • Enhanced Thermal Management Layout:Features a high-density network of cooling circuits designed to follow the part’s complex 3D profile. This advanced cooling strategy ensures rapid heat dissipation, significantly reducing cycle times and preventing thermal deformation in large plastic parts.
