Tooling quality is a combination of geometry, material, thermal behavior and process interaction. The sourcing file should contain the released drawing, tool material and treatment, inspection report and trial record. Critical datums need an agreed measuring method so the buyer and toolmaker do not approve different interpretations of the same nominal dimensions.
A useful trial reproduces the intended production material and operating window. Warm-up, steady-state run length, temperatures, force or pressure, cycle, sample positions and observed defects should be recorded. If the tool is adjusted, the final geometry and trial result must be linked to the revision that will be shipped and maintained.
Commercial terms should address design ownership, confidentiality, duplicate tools, maintenance, storage and end-of-life disposition. Spare heaters, sensors, inserts or wear components may be more important than a small tooling-price difference. Packing must protect precision surfaces and provide lifting and recommissioning instructions for the destination plant.
