Hydraulic baler is mainly used in steel plant and metal scrap recycling center, steel recycling and processing industry and nonferrous, black metal smelting industry. The hydraulic baler can compress all kinds of metal scraps (steel shavings, scrap steel, scrap aluminum, scrap copper, waste stainless steel and scrap automobile waste) into various shapes of qualified furnace charge, such as cuboid, octagonal, cylinder and so on, which can reduce the transportation and smelting costs and increase the furnace charging speed.

Also known as hydraulic metal packer, The development and application of hydraulic metal packing Du machine in China started in the mid-1980s. The ultimate goal of hydraulic metal baling machine is to extrude all kinds of metal scraps (steel shavings, scrap steel, scrap aluminum, scrap copper, waste stainless steel and scrap automobile waste) into cuboid shaped qualified furnace charge, which can not only reduce the transportation and smelting costs, but also improve the furnace charging speed. With the development of science and technology and the improvement of people's living standards, the metal scraps of various industrial departments and the wastes of metal products for daily use are increasing, which will undoubtedly pollute the human environment; on the other hand, with the continuous consumption of human society, all kinds of mineral resources will gradually decrease.

How to use metal waste, that is, to prevent pollution and turn waste into treasure, has become an important research topic in front of mankind. In recent years, people from all walks of life have attached great importance to improving the general ability and multi-functional integration ability of packaging machinery and the whole packaging system.

At present, China's packaging machinery is still mainly imitated, and foreign products are slightly improved, not to mention development and research. In enterprise management, production and processing are often emphasized, research and development are ignored, and innovation is not enough, Therefore, we should dare to innovate, explore research and practice in our own aspects, strengthen our own technology, and make our own contribution to the development of packaging machinery in China.
