Four key points for the development of China's car

  • Detail

In recent years, with the rapid development of China's economic construction, the paper product packaging industry is becoming more and more prosperous, and the requirements for technology and equipment are becoming higher and higher with the continuous updating of products. The paper packaging industry urgently needs advanced equipment for the design and manufacturing of the machinery manufacturing industry, so as to jointly participate in the international competition. Recently, the paper products packaging Committee of China Packaging Technology Association put forward four suggestions on the development of carton machinery manufacturing industry

I. The production of corrugated board should research and develop high-speed vacuum adsorption corrugated rollers to improve the stability of equipment operation and reduce the accident rate. Appropriately limit the manufacturing of single corrugated board machines with low technical content, high consumption and low efficiency. Packaging machinery should develop electromechanical integration technology, computer control technology and module technology, and improve the level of design and manufacturing

II. In view of the rapid development of micro corrugated board in foreign countries and the actual needs of China, mechanical component manufacturing enterprises need to strengthen the development and production of fine corrugated rollers. Machinery manufacturers should improve the corresponding box making mechanical fatigue testing machine, which is a precision instrument of clothing tension testing machine for testing the fatigue characteristics and fatigue life of materials, so as to promote the development of micro corrugated boxes in China's carton factories

III. mechanical parts should be produced in a general and professional way. On the one hand, it can avoid unnecessary troubles caused by poor universality and interchangeability to the maintenance of the paper packaging factory. On the other hand, it is beneficial for the whole machine manufacturer to reduce costs and reduce the capital investment required to improve the quality of parts

IV. carton printing has developed from monochrome printing to multi-color printing. The multi-color printing of carton enterprises in China is starting. Although in general, due to the constraints of plate quality, printing plate, plate making technology, printing machinery and other conditions, there are still few beautiful printed cartons in China, this is a development trend. It must be noted that the development of flexographic printing is a way to reduce the production cost of cartons. Although flexographic printing of cartons has just started in China, we should clearly see its potential vitality. It is necessary to constantly summarize the experience of improving the surface quality of AC paperboard, corrugated roller, flexible printing plate and plate making technology, printing operation technology, and the quality of low-quality non critical ink. Through practice, it is difficult to break through the difficulties of polyurethane resin
