Enamelled production quality control
In the 1960s and 1970s, as the leading manufacturer of enameled wire industry, Shanghai China Power Plant, the annual output was less than 3,000 tons. At that time, the annual output of the enameled wire of Fuzhou Electric Wire Factory (predecessor of Datong Company) was less than 1,000 tons. China needs other types of enameled wire to be imported. At that time, the output was only 4.55% of the global production, and less than 5%. Since the beginning of the 1980s, China has entered the market economy and implemented an open policy.
More than 20 companies in China have introduced nearly 200 enameled wire production lines from Austria, Japan, Italy and Taiwan, and introduced more than 700 enamelling machines. The total production capacity of the sets and testing instruments is about 300,000 tons. Among them, the equipment produced by Austrian MAG Company is the most, accounting for more than 80%, which makes the product structure, equipment level and manufacturing technology of China's enameled wire industry rapidly improve and close to or reach. The international advanced level has greatly shortened the gap between China and the international enameled wire industry.
From the product structure, product quality and market supply scale, it basically meets the demand for enameled wire in emerging industries such as domestic appliances. The national enameled wire production expanded from 50,000 tons in 1980 to 100,000 tons in 1990. In 2000, the national production and sales volume exceeded 300,000 tons, thus entering the second place in the world of enameled wire production and demand.
After more than 50 years of development, China's enameled wire industry has formed a production capacity of over 700,000 tons.
