1. The upper die and the lower die must be concentric, that is, the upper die and the lower die must be corrected. When the die is concentric, the upper die and the lower die can be accurately matched, and the buttons that are punched out will not fall out.
2, the machine can not be adjusted too deep when the pressure adjustment, adjusted too dark, easy to change the button to guide the button to damage or fall off, adjust the pressure is too shallow and afraid of the button is not easy to fall off easily, so more The depth of hitting the mold is based on experience. The simplest method is to press the back button and pull it out with a vise. It is difficult to pull it out and make a difference.
