Upper Die
First, compare the completed die-cutting mold with the drawing or sample to see if it meets the requirements. Check whether the blade of the steel knife has any notches and the sharpness of the blade. Whether the position of the steel knife and the drawn steel lines is accurate, whether the knife lines for making holes and grooves are full knives, and whether the turning positions of the lines are rounded corners or right angles. In order to facilitate the removal of waste materials, are the two steel knife interfaces tightly fitted into one piece? Are there any sharp corners or other issues at both ends of the steel knife interface? If the die-cutting mold has the above problems, the technicians from the die-cutting mold factory should be called immediately for correction or a new die-cutting mold should be made. Then install the prepared die-cutting machine.
Place the base plate
Since most punch presses are flat-pressing flat and the bottom of the punch is solid iron, a base plate is usually placed underneath to facilitate die adjustment.
Adjust the pressure
After placing the base plate, you can adjust the pressure. First, start the machine and test the stamping a few times to flatten the steel knife. If there are uneven marks on both sides of the base plate, you should adjust the pressure or increase or decrease the gasket layer to make the pressure along the knife line consistent. It is also necessary to ensure that the die-cutting position is centered, so that production will be faster and more material-saving.
Pressure test die-cutting
After completing the above work, several products should be stamped out first to compare with the samples to see if they meet the standards or if there are other burrs or other problems. After being inspected and confirmed by the inspectors, mass production can be carried out.
Positioning
After confirming that mass production is possible, most die-cutting processing technicians will position the materials. This facilitates production and reduces more procedures for the die-cutting technicians.
Formal die-cutting
Formal die-cutting does not mean that no problems will occur during the die-cutting process. Regular inspections must be carried out to ensure that any issues are promptly addressed.
Clear away the waste materials.
Finished product inspection
The finished products need to be spot-checked after being punched out.
Point packaging.
