All-electric injection molding machine has a series of advantages, especially in environmental protection and energy-saving advantages, due to the use of servo motor injection control and high precision, speed is also more stable, but also multi-level adjustment. However, all-electric injection molding machines are not as good as full-hydraulic injection molding machines in terms of service life, and full-hydraulic injection molding machines must use servo valves with closed-loop control to ensure accuracy, and the servo valves are expensive and increase the cost.
Electric-hydraulic injection molding machine is a new type of injection molding machine that combines hydraulic and electric drive. It combines the advantages of high-performance and all-electric energy-saving features of full-hydraulic injection molding machine. This electric-hydraulic combined injection molding machine Has become the injection molding machine technology development. The injection molding industry is facing a rapid development opportunity. However, in the cost structure of injection molding products, electricity costs account for a considerable proportion. According to the needs of injection molding machine equipment processes, injection molding machine oil pump motor power consumption as a proportion of the entire device power consumption From 50% to 65%, it has great potential for energy saving. Designing and manufacturing a new generation of "energy-saving" injection molding machines has become an urgent need to focus on and solve problems.
After China's accession to the World Trade Organization (WTO), foreign machinery manufacturing accelerated its transfer to China. Some well-known injection molding machine companies in the world, such as Germany's Demark, Krupp, Badenfele, and Japan's Sumitomo Heavy Industries, have entered the market. "In China, some have further established a technology center. The entry of foreign injection molding machine manufacturers has brought vitality to the Chinese injection molding machine industry, and has also made Chinese injection molding machine manufacturers full of opportunities and challenges.
In the development process of the injection molding machine industry in China, the traditional route has always been adopted. The early injection molding machines were all hydraulic type. Due to the needs of environmental protection and energy saving, as well as the mature application of servo motors and the sharp drop in prices, all electric motors have been used in recent years. The number of precision injection molding machines is increasing. According to statistics in 2001, China's imported injection molding machines use foreign exchange of 1.12 billion U.S. dollars, while exports of injection molding machines earned only 130 million U.S. dollars, and imports far exceed exports.
At present, China's injection molding machine products are mainly concentrated on general-purpose small and medium-sized equipment. In the 1980s and 1990s, the supply of low-grade products exceeded the demand, the manufacturing capacity of machinery was surplus, and the efficiency of enterprises decreased. Some varieties, especially ultra-fine large-scale high-end products, are still blank and still need to be imported.
Ripple wall Paper Cup cup is an advanced disposable paper container used for daily drinking. It is in the shape of a mouth cup. The outer layer is a corrugated paper cup wall arranged neatly. It has a very strong heat insulation effect. It is a new type of paper cup further improved on the basis of disposable paper cup.
Material: coated paper cup paper and corrugated paper. The commonly used film coated paper in corrugated cups is divided into double film coated paper and single film coated paper. The thickness of film coated paper usually used is 218g to 300g. The thickness of corrugated paper used for corrugated cup ranges from 280 g to 340 G.
