Realistic die life by alloy, the three failure mechanisms that kill tools, preventive maintenance intervals, nitriding options, weld repair limits and cost per part.
Which aluminum die castings can be heat treated, why blisters form, T5/T6/T7 windows with real time-temperature data, distortion control and how to specify it.
Thin-wall aluminum die casting limits: flow length vs wall thickness tables, filling time calculations, rib and fillet rules, distortion control and inspection.
How to powder coat die cast aluminum without blistering: pretreatment chain, outgassing bake, powder types, cure windows, edge coverage and adhesion testing.
Gate, runner and parting line removal for aluminum die castings: trim press setup, band sawing, robot vs manual grinding cost per 1000 parts and acceptance criteria.
Why die cast aluminum anodizes badly, which alloys work, the mechanical prep sequence before anodizing, common defects and how anodize-specific acceptance is tested.
