1. Select the punching machine (including type and tonnage) according to the punching force calculated by the mold design, the size of the mold, the closing height, etc.

2. Start the press, comprehensively check whether the clutch, brake, slide and other parts are normal, whether the operating mechanism is reliable, and there is no continuous impact phenomenon.

3. The pad iron under the die, generally 2 pieces, must be ground out at the same time on the grinder to ensure that the mold is installed parallel and vertical. Intercalation of the cushion iron is not hindered by blanking while being as close to the center of the mold as possible.

4. Several sets of pressure plates and T-head pressure plate screws should be prepared for corresponding use with the mold. The front end of the platen should not touch the straight wall of the lower die. Emery cloth should be padded between each contact surface, and screws must be tightened.

5. When installing the mold, pay great attention to the screws and nuts on the lower mold not touching the upper mold (the upper mold falls and closes).

6. Adjust the mold as much as possible with manual, not maneuvering.

7. In order to improve the blanking performance of the substrate, the paper substrate should be heated. Its temperature is better at 70 ~ 90℃.
