Automobile die-cutting machines have always been a major procurement for automobile production enterprises, and die-cutting machines play a very important role in production. Enterprises are very cautious in purchasing such equipment. Only by understanding the type of equipment, understanding market trends, and understanding one's own needs can one purchase satisfactory equipment.
The key to the quality of die-cutting machines
The quality of a die-cutting machine largely depends on the quality of the die-cutting plate. Only by having good quality and processing convenience, flatness, and robustness can the quality and accuracy of the die-cutting plate be guaranteed. It is understood that the most popular version in China is the multi-layer large adhesive version, while in foreign countries, fiber plastic version and sandwich steel version are commonly used. Multi layer wooden plywood boards are susceptible to deformation caused by changes in environmental temperature and humidity, which brings many inconveniences to die cutting production and storage. At the same time, the dimensional stability of multi layer wooden plywood boards is poor, with a dimensional error of generally 0.15mm~0.70mm. However, the dimensional errors of fiber plastic boards and sandwich steel boards are 0.13mm~0.30mm and 0.10mm~0.20mm, respectively
A considerable number of domestic enterprises have a misconception that they do not attach great importance to the supporting links in the die-cutting process such as bottom molds (female molds or backing) and sponge pads. For example, sponge pads with different hardness should be used for different structures of cardboard boxes and different cutting indentation lines of cardboard boxes. There are 5 types, 8 types, or even 10 types in foreign countries, while only 2 types are used in China, and some only use 1 type.
Enterprises should comprehensively consider the differences in benefits caused by equipment quality issues. High quality die-cutting equipment must be equipped with high-quality die-cutting plates, die-cutting tools, bottom molds and other raw and auxiliary materials, as well as processing techniques, otherwise it will only fall short. Even if a small step is not taken seriously, it will affect the die-cutting accuracy and the final quality of the finished product.
With the development of recent years, domestic die-cutting machines have reached a high level in many technical parameters, some even approaching international standards. However, domestic die-cutting machine manufacturers still face an extremely severe situation. At present, domestic die-cutting machine products are mainly concentrated in mid to low-end levels, and most of the high-end die-cutting machines used by domestic enterprises are still imported products. The main reason for this is that most domestic die-cutting machine equipment uses mechanical positioning, unlike foreign products such as Boster that use photoelectric positioning. Some critical components also rely on imports; There is a significant gap compared to similar foreign products in terms of registration accuracy, product stability, and reliability. A considerable number of products may undergo changes in certain important parameters after a few years of use. Therefore, domestic die-cutting machine manufacturers should make efforts in mechanical technology innovation and focus on the research and development investment of future high-end equipment.
