The Application Of Mold Cutting And in Material PE Protective Film

1. Types of facial material
Noodles can be divided into two categories: paper and film.
The cut -off of the paper class is slightly inconsistent with the film material. Although theoretically, PE protective film manufacturers must cut the noodles and adhesives together when cutting, but theoretically mold -cutting paper is a comprehensive result of cutting tool cutting and fracture of paper. The paper is also squeezed on both sides, so relatively speaking, the mold cutting accuracy of paper materials is not very high. When analyzing samples, some labels are often labeled. This is because the material fibers are thick and naturally break.

Based on paper -based molding signs, and thinking about the wear of the blade, the perspective of PE protective film manufacturers is 52 ° politely polite. The distinction force will exacerbate the phenomenon of breaking materials.

The mold cutting of the film, and the PE protective film manufacturer simply puts on the process of completely cutting. Because the film materials are mostly tough and do not break naturally, two -thirds are not appropriate. It is necessary to completely cut through or four -fifth of the thickness.

2. The intensity of the strength of the PE protective film manufacturer's facial material is related to the thickness of the same surface material, the fiber (polymer) structure is related to its own humidity. In the mold cutting process of PET protective membrane materials, the biggest factor associated with the facial material is the speed of waste. The greater the humidity of the situation, the weaker the strength of the PE protective film manufacturer's material after the moisture.

When designing the layout, according to the strength of the material, the dismissal size and exhaust speed of the discharge label through the implementation of the reasonable inserted label can not only improve the production efficiency, but also add the material.

3. The thickness of the thickness of the facial material directly affects the depth of the mold cutting. The thicker the material, the more casual cutting. Because the thicker the material, the greater the tolerance of the mold cutting, the smaller the chance of cutting the bottom paper. Relatively speaking, the material is thin, and the defects of cutting the bottom paper at will. For example, a facial material is distinguished by the unanimous flat -pressed flat label cutting machine 80g/m2 and 60g/m2. It was found that the mold cutting of 80g/m2 was normal, and the material of 60g/m2 was replaced. When cutting, the phenomenon of discharging and breaking, bottom paper cutting, and losses were often stopped. Large throw. There are many notes in this kind of situation. Assuming the use of a round -up molding method or reducing the cutting area of the mold, PE protective film manufacturers use high -precision equipment, etc. This phenomenon can be added or avoided.
