Short answer: Permanent mold casting pours molten metal by gravity into a reusable steel (or iron) mould, delivering denser, more dimensionally accurate parts than sand casting and higher volumes than one-off moulds — but below the throughput of high-pressure die casting. It suits aluminium, magnesium, zinc and copper alloys for automotive, hardware and machinery components where a semi-permanent tool pays back across thousands of parts.
