Early in the morning, the machinery of Nantong Jianghai capacitor Co., Ltd., located in Pingchao Town, roared, and the workers were busy in the workshop. Yu Yunguo, the process director of the third Manufacturing Department of the company, who was recently rated as "excellent migrant workers in Jiangsu Province", wore blue overalls to check the product quality on the workshop production line as usual.
In 1986, Yu Yunguo joined Nantong Jianghai capacitor Co., Ltd. to work. In addition to eating and sleeping, he spent almost all day in the workshop and found out the electrolytic capacitor operation process, production process and equipment operation standards bit by bit. "At the beginning, I didn't know how to do it. I read more, learned more, pondered more and worked harder. I didn't expect to learn it soon." Yu Yunguo recalled. From the front-line staff of the production department to the leader in charge of technical process production, he has made ingenious products that keep improving with his persistence and perseverance.
"After graduation, he came to work here. He started as a worker step by step. He was able to endure hardships and was willing to study hard. He made a lot of contributions to the company in terms of technology." Speaking of yuyunguo, xuyonghua, vice president of the company and chairman of the labor union, was full of praise. It takes ordinary people two or three years to learn how to operate electrolytic capacitors. Yu Yunguo became the main operator in only one year. He takes "diligence first" as his working principle. Even late at night, as long as the work needs, he will rush to the scene at the first time. With this research strength, yuyunguo has developed a number of technical transformation projects to make the "flower of cost reduction" take root in the enterprise.
In order to cooperate with the development of 5g new infrastructure market, improve product quality and reduce production costs, Yu Yunguo led the project of "reducing the leakage current of high voltage and ultra-high voltage aluminum electrolytic capacitors". On the basis of making full use of the company's self-developed and self-produced foil and cooperating with the transformation and upgrading of existing equipment, combined with TRIZ, lean and other methods, Yu Yunguo successfully solved the problem of large leakage current of high voltage and ultra-high voltage aluminum electrolytic capacitors. The project has won a number of invention patents and won the third prize of Jiangsu division of 2021 China innovation method competition. "The poor electrical performance rate of the final product of this project is reduced to 27.92%, which is expected to save 7.172 million yuan for the company every year." Yuyunguo.
Nowadays, with the upgrading of household appliances, there are more and more compact products. In order to meet the market demand, Yu Yunguo proposed to design the welding needle type high-voltage and small capacity products into lead type, change the conventional installation mode of capacitors and form them by side bending. Once launched, they will be welcomed by the market. "We have designed and tested again and again to promote the upgrading of products. Now it is widely used in international well-known brands such as Samsung, Infineon, LG and Siemens, which has greatly increased the profits of the enterprise." Yuyunguo said that although the process of overcoming technical difficulties is hard, it is very meaningful. "I cherish the process of working hard for every high-quality and low-cost product, which deeply reflects the value of our workers."
Over the past 36 years, Yu Yunguo has been working hard at the front line of capacitor product innovation and R & D, making continuous breakthroughs and promoting the optimization and upgrading of enterprise technology. Today, he not only undertakes the technical and technological work in the workshop, but also undertakes the test of many new products and processes. He is a real technical and technological backbone. According to xuyonghua, Yu Yunguo has successively obtained 10 authorized patents for new products and processes developed under his leadership, including 3 invention patents, 7 utility model patents and 3 pending invention patents, which has solved a series of technical and technological problems for the company, effectively improved product quality and reduced production costs. He is recognized as a "craftsman expert" in the company.
"It's a long way to go. I'll go up and down to find out" is Yu Yunguo's work creed. Technological innovation and excellence again and again. With excellent technology and love for work, Yu Yunguo has won the honors of position expert and advanced individual of the company for many times. In April last year, he successfully won the honorary title of "TongZhou craftsman" and recently was rated as "excellent migrant workers in Jiangsu Province". "This is my affirmation and inspiration. In the future, I will spare no effort to give full play to my talents, lead our front-line team and make greater contributions to the development of the company."
