What Is Die Casting? Process, Materials, and Design Rules from a Manufacturer
Die casting is a metal casting process that injects molten metal into a reusable steel mold — the die — under high pressure, typically 10 to 175 MPa. The metal solidifies within seconds and is…
LM25 Aluminum Casting Alloy: Properties, Equivalents, and Specification
A purchasing manager sends a UK drawing marked "LM25-TF to BS 1490" to three suppliers. One quotes A356, one quotes ADC12, and one replies asking whether LM25 is a typing error. Two of them are about…
AlSi10Mg Aluminum: Composition, Properties, and Applications
An engineer sends a European drawing marked "EN AC-AlSi10Mg" to an Asian supplier and gets a quote back for ADC12. That swap is wrong, and catching it early saves a qualification loop. AlSi10Mg…
A383 Aluminum vs A380: Composition, Properties, and How to Choose
Your drawing says A380, the foundry quote comes back as A383, and the thin rib on your housing still shows cold shuts. Alloy questions usually arrive exactly like this, late in a project and tied to…
Zinc Pest: What Causes It and How to Prevent It in Zinc Die Castings
Zinc pest is a destructive intergranular corrosion that attacks zinc alloy die castings from the inside. Tiny amounts of lead, tin, or cadmium — measured in hundredths of a percent — segregate to…
Zinc Die Casting Surface Finishing Guide: Plating, Powder Coating, and Passivation
Zinc accepts a wider range of surface finishes than any other die casting metal. Its dense, low-porosity as-cast surface can be polished to a mirror, plated to jewelry grade, powder coated in any RAL…
Zinc vs Aluminum Die Casting: How to Choose the Right Metal
Zinc and aluminum are the two most common die casting metals, and the choice between them comes down to a short list of questions: how heavy can the part be, how hot does it get, how many do you…
Zinc Die Casting Design Guide (DFM): Walls, Draft, Ribs & Tolerances
Zinc die casting holds thinner walls and tighter tolerances than any other die casting metal, but those advantages only show up when the part is designed for the process. Wall balance, draft, rib…
Zinc Die Casting Process Explained: Hot-Chamber Steps, Parameters & Quality Control
Zinc die casting is a high-pressure process in which molten zinc alloy, usually a Zamak grade, is injected into a hardened steel die at 415–430°C, held under pressure until it solidifies, and ejected…
