How to choose a press?

2025,03,26

1. The nominal pressure of the press must be greater than the stamping process force. However, for processes with longer working strokes, it is not enough to just meet the size of the process force, but it is also necessary to consider meeting its working load curve.

2. The stroke of the press slide should be sufficient to ensure that the workpiece can obtain the required size in height and can be smoothly removed from the mold after the stamping process is completed. For drawn parts, the stroke should be more than twice the height of the workpiece.

3. The number of strokes of the press should meet the requirements of productivity.

4. The closing height, worktable size, slide size, die handle hole size, etc. of the press must be able to meet the correct installation requirements of the mold. For crank presses, the closing height of the mold should be between the maximum die height and the minimum die height of the press. The worktable size should generally be 50-70mm (single side) larger than the lower die seat of the mold for easy installation. The aperture of the pad should be larger than the projection size of the workpiece or waste material for leakage. The die handle size should be consistent with the die handle hole size.
