Shot blasting and grit blasting of aluminum die castings: media types, grit size, parameter windows, surface profile results and what blasting cannot fix.
Why die castings warp, realistic flatness capability by part size, design and process countermeasures, straightening fixtures and how warp wrecks automated finishing.
How much machining allowance a die casting needs by feature, datum setup for cast-then-machine parts, and how allowance choice changes finishing cost.
How to design insert die castings: insert preparation, retention features, thermal expansion mismatch, cycle time penalty, failure modes and inspection.
Vacuum die casting explained: target vacuum levels, evacuation timing, the porosity reduction you can actually measure, and when the investment pays back.
How die casting flow simulation works: fill pattern, air entrapment, cold shut risk, how to act on the results, and what simulation cannot tell you.
