Die Cast Dies

Durable, High-Precision Die Cast Tooling for Aluminum, Zinc, and Magnesium

When you need die cast dies that can withstand pressure, heat, and long production runs, Master Tool & Mold has the expertise and equipment to make it happen. We design and manufacture custom die cast dies for manufacturers in industries like automotive, lighting, aerospace, and consumer products, with a focus on repeatability, strength, and clean cavity definition.

Our team brings deep knowledge of die design principles, from thermal management and venting strategies to robust shutoffs and ejector systems. We specialize in building both unit dies and complete die sets, using premium materials like heat-treated H13 steel, and machining them to exacting standards with high-speed CNC mills and EDM technology.

Our die cast capabilities include:

Multi-slide and insert designs
Custom gate and runner configurations
Large-format cavity machining
Surface treatments for high-wear zones

Whether you're casting aluminum enclosures, zinc brackets, or magnesium housings, we build dies that maintain dimensional accuracy over long production runs. And when repairs or revisions are needed, we can rework or refurbish dies in-house to reduce lead times and minimize production loss.

As a full-service die cast tooling partner, we’re here to help you get better parts faster—with tooling that holds up under pressure.
