High-Precision Multi-Cavity Mold Core Insert | Custom CNC Machined Tooling Components for Technical Plastic Parts


Product Overview

This is a high-performance multi-cavity mold insert, precision-engineered for the most demanding injection molding applications. The insert features complex, ergonomically shaped cavities that require extreme dimensional accuracy and a superior surface finish.
At JST Mold, we utilize state-of-the-art high-speed CNC milling and EDM technology to create these critical tooling components. This sample highlights our ability to achieve intricate geometries and tight tolerances, ensuring that every molded part is consistent, functional, and aesthetically perfect for industries such as automotive, electronics, and medical devices.


Key Features

  • Precision CNC Machining:Visible high-quality machining paths demonstrate our ability to control surface finishes and achieve complex 3D profiles with micron-level accuracy.
  • Multi-Cavity Efficiency:The balanced multi-cavity layout is designed for high-volume production, maximizing output while maintaining perfect uniformity across all parts.
  • Superior Surface Quality:Optimized for parts that require "Class A" or high-gloss finishes, reducing the need for secondary polishing and improving the aesthetic of the final product.
  • Hardened Tool Steel:Typically manufactured from premium steels such as S136, NAK80, or 1.2344, hardened to HRC 48-54 to ensure exceptional wear resistance and a long service life.
  • Interchangeable Design:Our inserts are designed for easy integration into larger mold bases, allowing for quick maintenance or component replacement without extensive downtime.
