Factors affecting die-cutting quality

1. When the wood die-cutting plate does not evenly cut the wire, the seam is perpendicular to the table but not necessarily perpendicular to the die-cut plate. After the die cutting for a period of time, the die-cut plate is pressed and flattened, and the die cutter originally installed on the bent portion of the die-cut plate tilts, resulting in die-cut burrs and even die-cutting. No matter how you pressurize or fill the bottom, it cannot be solved.

2. The non-uniform thickness of die-cut media will cause the die-cut tapes to be of different heights. When the thin paper is die-cut, the high-strength tape will touch the paper first, and the paper will cause the die-cutting to take place. Secondly, the lower strip cannot effectively eject the paper to the die-cutting blade, so that the finished product can be bulk-packaged.

3, the expansion and contraction of wood die-cut plate. The quality of the wood is not strictly processed. After the die-cutting plate is made, there is still expansion and contraction, which will increase or decrease the size of the die-cut product. In severe cases, the oblique die-cutter will be squeezed or gaps will be created at the interface.

4. The service life of elastic rubber strips. The effective period of the rubber strip is only about two years. Generally, it needs to be stored in darkness, the elasticity of expired rubber strips deteriorates, and the rebound speed becomes slower. The high speed die cutting will shorten the service life of the strips.

5. The surface of the elastic rubber strip has a strip of leather on its surface that has no adsorption force on the paper. When the paper is cut at a high speed, it can be quickly pulled away and it will not be bulked. The surface of ordinary rubber strips has an adsorption force on the paper, and when high-speed die-cutting, the paper products are torn by tooth decay.

6. The glue quality of glue sticks is poor, so that the strips are displaced in the die cutting, so that the die cutting takes place, and die cutting flashes or even indentation cracks occur.

7. The hardness and height of the elastic strip do not meet the ideal requirements

8, the height of the indentation line is not reasonable, can not reach the full indentation effect

9. Inaccurate selection of groove width for indentation bottom mold

10. All kinds of unfavorable factors on the paper processing will affect the appearance of the finished carton (such as laminating, glazing, stencil cutting, and various fine processing in the production of die-cutting plates, etc.)
