Single Operation Die

The five-step route should be reviewed as a sequence of dedicated tools. In a single operation die set, each die can be assigned to blanking, piercing, pre-forming, final forming, or trimming as required by the part geometry. Because one left-hand and one right-hand component are produced together, the datums and mirrored features need to remain linked through every stage. A single operation stamping die should not correct an upstream locating error by forcing the part into the next form; stable nest location matters more than a tight-looking fit.

The 160 T press information must be checked with the actual shut height, bolster area, feed direction, and die clamping method. For a single stage operation die, loading and unloading can be manual or semi-automatic, but the operator should not reach across sharp trim edges. The single operation press die needs positive stops, finger clearances, and a dropping-off route that prevents the two parts from mixing or scratching.

During tryout, each operation is inspected before the full route is run. Hole position, trimming line, flange angle, surface profile, burr direction, and tool marks are recorded for both left and right parts. Single operation tooling is often easier to adjust than a combined die, but corrections still have to be tracked so one station does not hide a problem created earlier. The listed stamped part weights should be confirmed because the source data does not state the unit. A first-off part from each die should be retained with its operation number and correction record.

Release information should pair the press specification with the applicable die technical standards, plus the current 3D drawing and controlled 2D drawing. Material coating requirements, sample quantity, and the inspection datum plan will complete the review. The Single Operation Die can then be quoted against the confirmed five-operation route.
