Pass/Fail Checks for a Cold-Chamber Die Casting Machine FAT
A buyer's guide to defining measurable acceptance criteria for a cold-chamber aluminum die casting machine FAT, with practical checks and questions for the supplier.
For a cold-chamber aluminum die casting machine, the buyer's first FAT decision is whether acceptance will be judged on demonstrated machine functions or on cast-part quality, since the two demand different tests and witnesses. Agree the basis before the test plan is written.
For machine functions, ask the supplier to define pass/fail for clamp force across the listed 130–900 t series range, dry-cycle repeatability, shot position and velocity control, and cold-chamber pour and injection sequencing. For part quality, specify sample castings, cavity count, alloy, and which dimensions or defects count as failure. Treat catalog values such as clamping tonnage as reference figures, not guarantees for the supplied unit.
Useful questions for the RFQ or demonstration: Which checks are witnessed and recorded? What tolerances apply, and who supplies the gauges? How many consecutive cycles or castings must pass? What happens if a check fails—retest, adjustment, or rejection? Define acceptance in writing so both sides apply the same criteria.
Before requesting a quote, confirm with the supplier which FAT checks are standard, which are optional, what instrumentation and records are included, and how deviations are documented and resolved.
