Cold-Chamber Die Casting Machine: Prove It on Your Aluminum Part
A buyer's guide to requiring demonstration trials on the buyer's own aluminum workpiece, with practical questions for the RFQ, demo, and acceptance test.
Before signing off on a cold-chamber die casting machine, require the supplier to demonstrate it with your own aluminum workpiece, not a showcase part. Ask whether the trial will use your alloy and part geometry, and who supplies the die. A demonstration on a generic part shows little about how the machine handles your casting.
In the RFQ, request a trial plan: which clamping tonnage from the listed 130–900 t series is proposed, and why it suits your part. Ask for the shot parameters to be recorded and shared, and whether the trial runs at production cycle times. During the demonstration, compare measured castings against your drawing tolerances and agree how many parts constitute a valid run.
For acceptance, define pass criteria in advance: dimensional checks, visual defects, and repeatability across consecutive shots. Clarify whether the buyer's material and die are used, and who bears trial costs.
Before requesting a quote, confirm with the supplier what material and workpiece they will run, whether your die is required, how trial results are documented, and which acceptance tests are included.
