Corrugated cardboard box die cut design process

4, the pressure line processing

(1) Bending line deformation Figure 3-8

As shown in Fig. 3-8, it is a schematic diagram of a bad pressure line. In the die-cutting of such a pressure line, a phenomenon such as a breakage of a product folded portion occurs, mainly because the hardness of the pressure line is low. The machine used during processing is not good or is not operated properly, which is also the reason.

(2) The foot of the press line

The foot of the press line has an effect on the cloth bottom and should be treated as shown in Figure 3-9. Figure 3-9

(3) The length of the pressure line

In Fig. 3-10, when A> 0.3mm, the product's chamfer will be broken. Fig. 3-10

(4) The shape of the pressure line

The cross-section of the pressure line is not symmetrical about the centerline, as shown in Figure 3-11b, unilateral indentation will occur. Fig. 3-11

5, sponge on the cutting board

When attaching a sponge to a die-cutting plate, leave a suitable space for installing the bottom mold bar. Refer to the above figure
