Tongfeng Electronics adheres to the policy of "developing enterprises through technology", while introducing advanced capacitor film production line technology, actively absorbing and digesting advanced foreign technologies based on the company's actual situation and past experience, and vigorously carrying out equipment localization research and development work. The domestic development of the "edge membrane crushing system" has been successfully tested, saving the company more than 700000 yuan in funds and creating a good start for the completion and operation of the multifunctional membrane project with a total investment of 170 million yuan.

The multifunctional film project of Tongfeng Company belongs to the national high-tech industry. After the project is completed and put into operation, the company's capacitor film production capacity will leap to the world's first place. The edge film crushing system is one of the important links in the production line of this project, and importing the system from abroad requires more than 800000 yuan. The deputy commander-in-chief of the project, Chang Rongqing, convened relevant engineering and technical personnel to conduct a careful analysis and research on the system, and determined the feasibility of localizing the development of the system. During the development process, due to the fast speed of the new film line and the thinner film being pulled, the imported equipment in the past could not meet the process requirements of the new line, and it was naturally difficult to imitate it. In addition, the latest foreign technology lacked information, and the development encountered unprecedented difficulties. With the care and encouragement of the company's leadership, the technical personnel boldly conceived, carefully researched, and designed, and finally overcame the difficulties, and finally determined the system solution. After multiple simulations and on-site operation tests, it was shown that this system was significantly better than the current German Bruckner equipment, solved multiple technical problems such as fan film blockage, and the equipment only cost more than 90000 yuan in processing fees. This research and development work not only greatly saved engineering funds, but also further improved the technical level, providing a strong guarantee for Tongfeng Electronics to reach new heights in the fierce market competition.
