Energy-saving and emission reduction has become the main theme in today's society. Compared with traditional die-casting machines, energy-saving die-casting machines not only have excellent performance in terms of energy consumption, function, response speed and control precision, but also can save money for enterprises, so they are produced by die-casting machines. Manufacturers and users are welcome throughout. This means that China's die-casting industry will usher in a big leap.

According to the "2015-2020 China Die Casting Industry Market Prospect and Investment Strategy Planning Analysis Report", China's die-casting industry has continued to develop in recent years. With the improvement of technology level and core competitiveness, domestic die-casting machines have gradually participated in the world market. The expansion of the die-casting industry, on the one hand, provides a larger stage for the development of die-casting machines in China, and on the other hand, it puts forward higher requirements for the continuous advancement of die-casting machines.

As we all know, the process of die casting machine is generally divided into mold clamping, soup, injection, core pulling, mold opening, thimble, cooling, pressure accumulation and other stages. At each stage, the hydraulic pump is pumped out by the oil pump motor to each cylinder to drive the transmission organization. A series of actions, each of which has different matching of pressure and flow. In a working cycle of a die-casting machine, the part with a large load is a high-pressure clamping and injection stage, and the load in other links is small, and the load in the cooling process is simply zero. In the hydraulic system of the dosing pump, excess hydraulic oil is recirculated through the overflow valve. This process is called high pressure interception, and the energy loss formed by it is generally about 50%.
