Magnesium Die Casting Molds & Tooling

Moldie provides magnesium alloy die casting molds and tooling from initial design through mold trial. Utilizing hot-chamber-oriented tooling design, CAD modeling, and mold flow analysis, we manufacture custom molds for lightweight parts with high strength-to-weight ratios.

We engineer molds for magnesium alloys including AZ91D, AM60B, and AM50, tailoring material selection for targeted strength, corrosion resistance, or ductility.

Our tooling programs account for secondary operations so finished components can leave your line through CNC machining, surface treatments, powder coating, and assembly.

Operating under ISO 9001 certification, our quality control ensures full traceability using CMM inspections, spectrometry, hardness testing, and corrosion evaluations. We support mold programs from initial prototypes to high-volume production dies.

Magnesium Die Casting Expertise

Our magnesium die casting molds leverage the unique properties of magnesium alloys—lightweight nature, high strength-to-weight ratio, and excellent castability. By designing tooling for advanced hot-chamber processes and optimized process windows, we help you cast complex, thin-walled, near-net-shape magnesium parts with exceptional dimensional accuracy and surface finish.

Custom Magnesium Die Casting Molds

Every project begins with a conversation. Our engineering team collaborates with you from concept to completion, providing full design support including CAD modeling, flow simulation, and mold flow analysis.

We optimize gating systems, cooling channels, and ejection mechanisms to ensure defect-resistant casting with minimal porosity and maximum yield. Whether you need simple brackets or complex, thin-walled enclosures, we build custom magnesium die casting molds tailored to your exact specifications.

Alloy Selection and Material Optimization

We work with a broad range of magnesium alloys, including AZ91D, AM60B, AM50, and others. Each alloy offers distinct advantages—AZ91D provides excellent strength and corrosion resistance, while AM60B and AM50 offer superior ductility and impact absorption. Our team helps you select the optimal material for your application based on mechanical requirements, environmental conditions, and cost considerations. This expertise ensures that molds and alloy choice work together so your magnesium parts perform as intended.

Secondary Operations and Finishing

To help your casting line deliver fully finished components, we design molds with a comprehensive range of post-casting steps in mind:

Precision CNC Machining – Tooling planned so tapping, drilling, milling, and turning can achieve tight tolerances on critical features.

Surface Treatment – Mold design that supports chemical conversion coating, micro-arc oxidation, and painting for enhanced corrosion resistance.

Powder Coating & Painting – Aesthetic finishes tailored to your product requirements.

Assembly – Tooling programs that fit multi-component systems ready for shipment.

This tooling-focused approach simplifies your supply chain, reduces lead times, and supports consistent quality from start to finish.

Quality Assurance and Certifications

We are ISO 9001 certified and maintain a robust quality management system that governs every aspect of our magnesium die casting mold operations. Our inspection capabilities include:

CMM (Coordinate Measuring Machine) – For full dimensional verification.

Spectrometer – For real-time alloy composition analysis.

Projector (Optical Comparator) – For contour and profile inspection.

Hardness Tester – For material strength validation.

Salt Spray Test Machine – For corrosion resistance evaluation.

Pneumatic Measuring Tools – For high-frequency in-process dimensional checks.

Every mold program undergoes rigorous process control and final inspection, ensuring that as a magnesium die casting mold maker, we deliver tooling with full traceability and documentation.
