Precision CNC Machining for Custom Mold Inserts & Refurbishing

At Punch Tools, we manufacture and restore complex, tight-tolerance mold inserts, cavity blocks, and core pins using advanced precision machining techniques. High-wear molding environments demand extreme accuracy. Our toolroom utilizes high-precision CNC milling, wire EDM, and surface grinding to deliver or restore inserts to exact original CAD specifications.

We work with high-grade tool steels to machine intricate geometries, complex cooling channels, and sharp shut-off faces. Whether you need a replacement core insert machined from scratch or a worn cavity block refurbished to eliminate flash, our machining tolerances ensure seamless fitment within your mold base.

By targeting only the worn or damaged surfaces of your modular tooling, our insert refurbishment process extends the production life of your molds at a fraction of the cost of building a new tool set.
