Hot Chamber vs Cold Chamber Die Casting: How to Choose the Right Process for Your Part
The difference between hot chamber and cold chamber die casting comes down to one design decision: where the metal melts. In hot chamber die casting, the injection mechanism sits inside the molten…
Die Casting Tolerances: NADCA Standards, Charts, and Calculation Examples
How tight a tolerance can a die casting hold? For most aluminum and zinc parts, the NADCA standard answer is ±0.010 in (±0.25 mm) on the first inch, plus ±0.001 in (±0.025 mm) for each additional…
Die Casting Defects: 12 Common Types, Causes, and Solutions
Die casting defects are surface, internal, or dimensional irregularities caused by filling, solidification, tooling, or process parameter problems. In high-pressure die casting, where the cavity…
Die Casting Design Guide for Aluminum Parts: DFM Rules, Tolerances, and Cost Drivers
Most die casting problems are paid for twice — once on the drawing, and again when the mold has to be reworked. A 5 mm wall where 2.5 mm would do stretches cycle time and traps shrinkage porosity; a…
Die Casting Mold Design: Components, Key Decisions, and Tooling Cost
Die casting mold design is the engineering of the hardened steel tool that shapes molten metal under high pressure â covering the cavity and core inserts, the gating and runner system, vents and…
What Is Die Casting? Process, Materials, and How to Specify Your Part
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…
