Finishing in a carton die cutting is an important process, cutting a direct impact to the final molding tray. For the printing process of the cutting edges and appear easy to tear easily torn mouth, we interviewed a number of specialized printing and suppliers and ask them to talk about the cause of this problem and generate solutions.

1, the cutting edges of the problem

Reason: Contact point too

Solution: Contact point should be constantly in the boot large sheet of minimum for the best circumstances, and location of the point associated with the feeding direction of a linear distribution, so that sheets do not work in the oblique cutting machine, the tensile , Union Point is not easy to pull off, joint points can be the smallest mouth to tear the box easy to tear when the tear was.

Reason: do not cut through cutting

Solution: First check the version of quality knives, such as quality standards, knife-line highly consistent, sharp blade, then the next check whether there is die cut through the paper part, if any, that should be added pressure. If the part is not cut through, then the pressure is not enough, you can adjust the pressure that some equipment cut through, and then cutting through the added pressure to achieve the desired effect.

In response to these two issues, Jiangsu Unicom Sampoerna Printing Co., Ltd. that these problems are mainly caused by the die cutter. Clear waste in the use of automatic printing machines, blades, cutting die mold better than wood.
