Product Overview

This is a highly sophisticated 2-cavity precision injection mold engineered for parts requiring complex internal threads and lateral undercuts. The mold integrates an advanced gear-driven automatic unscrewing system, allowing for the seamless production of threaded components without the need for manual secondary operations.
At JST Mold, we specialize in "moving-part" molds. This tooling combines high-speed mechanical unscrewing with precision side-action sliders, making it the ideal solution for automotive fluid connectors, threaded caps, and high-performance industrial fittings that demand perfect thread integrity and structural precision.
Key Features
  • Integrated Automatic Unscrewing System: Features a precision gear-and-rack mechanism that automatically rotates to release internal threads during the de-molding cycle, ensuring high-speed production and zero thread damage.
  • Precision Side-Action Sliders: Equipped with multiple synchronized sliders to handle complex external undercuts and lateral features, allowing for intricate part designs.
  • 2-Cavity High-Efficiency Layout: A balanced 2-cavity design that ensures uniform material flow and cooling, providing identical part quality and weight across high-volume production runs.
  • Advanced Gear Engineering: The unscrewing components are manufactured with extremely tight tolerances to ensure smooth, repeatable motion and long-term mechanical reliability.
  • Premium Hardened Steel Construction: Built with high-performance mold steels such as S136, NAK80, or H13 (hardened) to withstand the mechanical wear of the unscrewing motion and provide a mold life of over 1,000,000 shots.
