How should the car die cutting machine be purchased

Automobile die cutting machine has always been a relatively large purchase of automobile production enterprises, die cutting machine occupies a very important position in the production, for the purchase of such equipment, enterprises are very careful. Understand the type of equipment, understand the dynamics of the market, and understand their own needs in order to purchase satisfactory equipment.

Die-cutting machine quality key

The quality of the die cutting machine depends largely on the quality of the die cutting plate, the die cutting plate only has good quality and processing convenience, flatness, robustness, in order to ensure the quality and accuracy of the die cutting plate. It is understood that the domestic is now more popular multi-layer glued version, and in foreign countries more fiber plastic version and sandwich steel version. Multi-layer wood gluing plate is susceptible to changes in ambient temperature and humidity, resulting in deformation, which brings a lot of inconvenience to die cutting production and die cutting plate storage, while multi-layer wood gluing plate dimensional stability is poor, the size error is generally 0.15mm ~ 0.70mm, The size error of the fiber plastic version and the sandwich steel version is 0.13mm ~ 0.30mm and 0.10mm ~ 0.20mm, respectively

A large number of domestic enterprises have a misunderstanding, they do not pay attention to the supporting links in the die cutting processing process such as the bottom mold (Yin mold or backing), such as the different parts of the cardboard box and carton cutting indentation line should use different hardness of the sponge pad, there are 5 kinds of 8 or even 10 kinds in foreign countries, and only 2 kinds of domestic use, and some only use 1.

Enterprises should consider the difference in benefits caused by the quality of equipment. High-quality die cutting equipment must be equipped with high-quality die cutting plate, die cutting tools, bottom die and other raw and auxiliary materials and processing technology, otherwise it will only fall short, even if a small link does not pay attention to will affect the precision of die cutting, affect the quality of the finished product.

With the development of recent years, domestic die cutting machine in many technical parameters has reached a higher level, and some even close to the international level, in spite of this, the domestic die cutting machine manufacturers are still facing an extremely severe situation. At present, domestic die-cutting machine products are mainly concentrated in the middle and low level, and most of the high-end die-cutting machines used by domestic enterprises are still imported products. The main reason is that most of the domestic die cutting machine equipment uses mechanical positioning, unlike Bost and other foreign products using photoelectric positioning, some key parts also rely on imports; Compared with similar foreign products, there is a big gap in registration accuracy, product stability and reliability, and a considerable number of products will change some important parameters after a few years of use. Therefore, domestic die-cutting machine manufacturers should work on mechanical technology innovation and pay attention to the future research and development investment of high-end equipment.
