Testing a Closed-Frame Die Forging Press on Your Own Steel
A buyer's guide to planning a demonstration of a closed-frame die forging press using the buyer's own steel workpiece, with practical questions for the RFQ and acceptance test.
Ask the supplier to run your own steel workpiece, not a demonstration blank, before you commit to a closed-frame die forging press. A press rated at 4,000 kN nominal capacity may behave differently once your die geometry, billet temperature, and handling are in play, so the demonstration should mirror your intended forming sequence as closely as the supplier's tooling allows.
In the RFQ, state the workpiece you will bring, the die set you expect to use, and whether the supplier can mount it within the stated 400 mm maximum die height. Confirm that the 110 mm slide stroke and 40 strokes/min stroke rate are reference catalog values and ask which configuration the demonstration unit will use. During the trial, compare formed parts against your drawing tolerances and record whether the press completes the stroke without stalling. Ask how the supplier will measure repeatability across a short run, and whether your operators can load and unload the workpiece under production-like conditions.
Before requesting a quote, confirm with the supplier what tooling and material preparation they will provide for the demonstration, who supervises safety during the trial, and how the acceptance test will define a conforming part.
