On April 25, 2004, Anhui Tongfeng Electronics Co., Ltd. invested 170 million yuan in the multi-function capacitor film production line technology transformation project officially passed the completion acceptance. The successful completion and production of this project not only made the company's capacitor film production capacity rank first in the world. At the same time, the project successfully produced the world's thinnest 3-micron capacitor film and the production speed of 280 m/min has reached the world's two limits in the field of capacitors, indicating that the bidirectional polypropylene film technology of Tongfeng Company has reached the world's first-class level.
In recent years, Tongfeng Electronics Co., Ltd. adheres to the principle of "developing enterprises through science and technology", and has formed a leading product with independent intellectual property rights -" electrical tri-film "through technological transformation and industry-university-research cooperation. Among them, the annual production capacity of metallized film is 4000 tons, the annual production capacity of AC capacitor is 400 million, the annual production capacity of new DC film capacitor is 300 million, the capacitor film production capacity is 8000 tons, and the production capacity and market share both rank the first or forefront of domestic peers.
The multifunctional capacitor film production line technology transformation, the company fully rely on its own technical advantages and years of accumulated experience, constantly explore the core technology of capacitor film production, on the basis of the introduction of foreign equipment, actively digest and absorb foreign technology, strengthen self-innovation ability, construction only equipment localization transformation and equipment bidding, which is to save 7.22 million yuan for the company. After a period of trial production, the production capacity of capacitor films of the production line has greatly exceeded its designed capacity, and reached 3600 tons. The newly developed new products, such as double-faced coarse films, ultra-thin optical films (3μm), not only fill the domestic gaps, but also make the production technology of polypropylene films close to the international level. At the same time, it also drives the development of the industry of high voltage full film power capacitor, which makes the company's international competitiveness increase rapidly.
