Selection of high and low peaks and knife patterns
When choosing high-quality die-cutting knives, attention should be paid to selecting high peak and low peak knives based on the thickness of the material being die-cut. High peak knives can cut both thin and thick paper, and can be used on single sheet automatic die-cutting machines or hand operated die-cutting machines that simultaneously cut two or three sheets of paper, with a wide range of applications. But if the user's product is single and all of them are thin cardboard, such as cigarette packaging production factories, which have long been die-cutting cigarette boxes with a thickness of less than 400 grams, then it is recommended to use a low peak knife, as these factories usually use automatic die-cutting machines, single sheet paper die-cutting, fast speed, large quantity, and low peak knife can meet the requirements. For the requirement of longer and more durable versions, because the stiffness of the short peak blade is higher than that of the peak blade, it is more stable under pressure and durable.
In addition, when choosing high-quality die-cutting knives, attention should be paid to the horizontal or straight grain treatment of the blade peak. Horizontal grain treated knives have better effects on die-cutting paper, are more durable, have higher stability and accuracy, and are not easy to crack after bending. The surface of straight grain treated knives seems to be very sharp, so when cutting on the steel plate surface, it is easy to become blunt after a short time, and also easy to crack after bending. Therefore, in addition to die-cutting film products, Choosing a straight grain knife is more smooth, but it is better to use a transverse grain treated die cutting knife for die-cutting paper products.
The high speed of today's automatic die-cutting machines has increasingly high requirements for die-cutting knives, prompting die-cutting knife manufacturers to develop high standard products. The Supreme knife, launched by Austrian company Bohler, which leads the production technology of world die-cutting knives, is coated with a special metal coating on the blade peak of high-quality die-cutting knives, filling out capillary pores and gap pits, making the blade peak smoother, reducing friction between the knife and paper, reducing mechanical wear, and preventing the generation of paper dust. More suitable for die-cutting and papermaking; Especially for products with high requirements, such as medicine boxes, food boxes, and packaging boxes that do not allow paper dust to stick, Supreme knives should be used, with a maximum of 2 million die-cutting times. It is currently the most high-end die-cutting knife and can be called the "king of die-cutting knives".
Die-cutting machines, knife molds, circular die-cutting machines, flat die-cutting machines, and adhesive die-cutting machines all need to be carefully distinguished and selected based on different materials, etc
