Take you to distinguish between good and bad quality die cutter

There are four characteristics of a high-quality die cutter, specifically the use of high-quality steel, superb surface decarburization, excellent heat treatment, and high precision. 1. Selection of high-quality steel: The molecular structure of steel is compact, the blade body is flexible, and there is no rebound after bending, and the molecular structure remains tightly connected. 2. Exquisite surface decarburization: The relatively brittle carbon molecules are withdrawn from the surface of the die cutter, so that the blade will not be embrittled when it is bent, resulting in the blade being broken. Like a layer of soft leather to wrap the blade, it is more convenient for bending. 3, excellent heat treatment: according to the different requirements of customers to adjust the die cutter to different hardness, and soften the knife body to facilitate bending and adjust the hard blade to make it durable. 4. Extremely high precision: The higher the precision of the die cutter, the shorter the time for pressure adjustment of the die cutter, the lower the mechanical wear, the faster the production speed, and the better the die cutting effect. Special self-adhesive trademark die cutting, no precision die cutter is not qualified.

How to distinguish between high-quality and low-quality cutting knife: 1, the knife blade by the quenching knife blade due to soft body, hard blade, usually known as a soft knife. The soft knife, the quenched area thickness has a great influence on the durability, the quenching area is large, and the greater the mechanical pressure capability of the supporting blade body is. On the other hand, when the contact area between the relatively hard blade and the relatively soft blade body is small, the hard part will be recessed into the soft part, or it will easily fall off, and the bearing force will be insufficient or reduced to zero, that is, the knife life will be shortened. Of course, the area of ​​the quenched layer cannot be increased without limit. Excessive area of ​​the quenched layer will affect the bending of the die cutter. Because of the importance of the quenched layer, plus the larger area of ​​the quenched layer, the higher the tool cost, all the unscrupulous manufacturers even use the coloring method blade to paint the ink on the blade and say quenching to deceive the user as the user should have. Clear-headed, don't be tricked by fake knife. 2. The higher the precision, the better the quality of the die cutter and the higher the grade. Taking Bohler die cutter as an example, the precision is ±0.02mm, and the accuracy of A, B and C cutters can reach ±0.007mm. For example, A type cutters can be used for a long time, then the precision of type A cutters can be Over ±0.007mm (B class, C class), this approach is convenient for the user. As long as the user specifies the purchase of the same type of knife, the price does not change, but can get ± 0.08mm when the precision workmanship is very large, while the ordinary make-up paper is only 0.05mm thick, the tolerance is difficult to use to make up the bottom of the paper. Especially for high-precision die-cutting, these rough die-cuts simply fail. 3. The selection of different hard bottom varieties will help adapt to different needs. Some brands have only one or two hardness knives, which are simply not adequate for die-cutting thicker materials. On the other hand, if there is only a very hard knife, it is very problematic for the complex pattern wood molding. Or sometimes the user barely uses the same knife and different requirements for die-cutting production, failing to achieve the best results, so multi-category selects high-quality brand features.

When selecting a high-quality die cutter, it is necessary to select the peak and dwarf cutters according to the thickness of the die-cut material. The peak knife can not only cut thin paper but also can cut thick paper. It can be used on a single sheet automatic die-cutting machine, and can also be used on a die-cutting machine for simultaneously cutting two or three sheets of paper to achieve a wide range of use. However, if the user's products are single, and all are thin cardboard, such as cigarette packs, long-term die-cutting is less than 400 grams in thickness, then we recommend the use of daggers, because these plants usually use automatic die-cutting machines. Die-cutting, fast speed, large quantity, dwarf knife can satisfy. For a longer version, it is more durable. Because the dwarf blade has a higher blade stiffness than the peak, the pressure is more stable and the durability is longer.
