Electric Mold Application

Electric tool refers to a tool that is operated by hand and driven by a small power motor or electromagnet through a transmission mechanism. It is widely used in construction, housing decoration, automobile assembly, engineering machinery, electric power, metallurgy, mining, bridges, horticulture and other fields, and has entered a large number of families.


Electric tools are mainly divided into metal cutting electric tools, grinding electric tools, assembly electric tools and railway electric tools. The precision of electric tools is one of the important indicators reflecting a country's manufacturing capacity and industrialization capacity, and plays a very important role in improving the national economy, energy utilization, environmental protection and people's quality of life. In order to consolidate the industrial foundation, improve the quality and efficiency of industrial development, and promote China's transformation from a large manufacturing country to a powerful manufacturing country, the state has issued a series of industrial policies to promote the development of electric tool industry.
