The role of rubber strips and sponges is to use their elasticity to quickly separate and peel off die-cut semi-finished products and their corner scraps from the die-cutting plate to achieve a continuous, normal die-cutting process.
Generally, the thickness of the rubber strip is preferably 3 mm to 5 mm higher than the edge of the blade.
The distance between the sponge block and the edge is more.
These data are not dead, or should be properly controlled according to the characteristics of the product, appropriate adjustments, in order to achieve better results.
Why do you want to make appropriate adjustments?
This is for different cardboards.
We all know that for three-layer single-pit (楞) cardboard, especially for cardboard with a large area, it is difficult to ensure that it does not bend.
Then the flatness of the cardboard is not good, and the rubber strip or the sponge is too thick. When the pressure is pressed, the rubber strip and the sponge are easily rubbed to the raised paper surface, so that the paper is displaced and the die cutting is not accurate.
Manufacturers of die-cutting dies are manufactured in standard sizes. They don't know if the cardboard you are using will be flat or curved, so you need to make reasonable adjustments by the operator on site.
