China News Service, Hangzhou, April 4 (Reporter Zhao Yejiao, Zhao Xiaoyan, Huang Hui) At the beginning of the outbreak of the New Coronary Pneumonia epidemic, the production of medical protective clothing, surgical masks, temperature measuring guns and other anti-epidemic materials was on the way to the university exam. In the face of this big test, Zhejiang tried every means to ensure the supply of emergency supplies and speed up the resumption of production of the province's epidemic prevention materials production enterprises. It only took more than 1 month to reverse the difficult supply of medical protection materials. The reporter noted that some “invisible” manufacturing enterprises with leading and core technologies “surfacing” have played an important role in the college entrance examination, not only “buffering” the impact of the epidemic, but also finding new opportunities for high-quality development in the future.
If the meltblown cloth is the "heart" of the mask, the meltblown die head is the "heart" of the meltblown cloth, which directly determines the protective effect of the mask.
After the outbreak, Li Pucha, deputy general manager of Jingcheng Times Group Jingcheng Mould Machinery Co., Ltd., received countless calls, 90% of which were directed to the "meltblown die head", and the order volume was blown out. During the epidemic, the total order volume has reached 180 orders.
On March 5, the Zhejiang Provincial Development and Reform Commission sent a letter to the company requesting it to provide Sinopec with two sets of 3.2-meter melt-blown die heads on April 6, but the production cycle of one set of melt-blown die heads takes 3-4 months. .
How to improve production efficiency to complete the task in the shortest time?
Sincerity Times Group promoted the production of meltblown die heads to an emergency state, mobilized the steel raw materials reserved by the company, and about 400 employees work in three shifts 24 hours a day. "We strive to shorten the manufacturing cycle to 1-2 months. From April, a large number of customers will be delivered to the users one after another. Sinopec's two sets of meltblown die heads are already being loaded today." Li Pucha said.
Not only the masks, but also the small amount of temperature guns have become the most sought-after goods in the epidemic. The core is the infrared temperature measurement chip.
On the third day of the New Year's Day, General Manager Luo Weishao of Hangzhou Jinghua Microelectronics Co., Ltd. (hereinafter referred to as "Jinghua Micro") received an urgent call from a colleague: "The inventory of infrared temperature measurement chips for about half a year is all booked within one day. "

Five years ago, Jinghua Micro began to dig into the field of infrared temperature measurement, and accumulated hundreds of mature and stable overall solutions. The chips have been mass-produced and applied. At present, it is the largest infrared temperature measurement chip supplier in mainland China. The company previously shipped about 1 million pieces per month. In response to the epidemic, Jinghua Micro has increased its production capacity by more than ten times in just a few weeks. Currently, it supplies dozens of large-scale and large-scale production customer manufacturers. During the epidemic, the cumulative shipments exceeded 10 million pieces, ranking first in China. One.
Hangzhou Haodeli Intelligent Technology Co., Ltd. mainly produces graphene protective clothing and other medical products. The company worked with a team of professors from Zhejiang University to set up a technical research team. It took only 3 days to develop graphene protective clothing, and overcome difficulties such as fabric procurement, equipment transformation, and insufficient staff. Speed, forming effective capacity.
It is worth mentioning that as a large manufacturing province, these "invisible" manufacturing companies not only "buffer" the impact of the epidemic, but also usher in new development opportunities with their leading and core technologies.
Twenty years ago, domestic meltblown die heads were basically imported from Europe and Japan, and Chinese companies had little way to produce high-end domestic equipment. Sincere Times Group is one of the earliest "people who eat crabs".
Starting from learning and referring to foreign advanced technology, as more practice, application and experience are accumulated, combined with advanced analysis systems, a more professional talent team is formed. Jingcheng Times Group successfully developed a self-contained set in 2015 Products, currently in the high-end meltblown die head market, market share of 60% -70%, even 80% during the epidemic. Because of the meltblown die head technology, on March 3, Jingcheng Times Group was also included in the list of key enterprises in the State Council's anti-epidemic materials-related equipment.
"Melt-blown cloth needs to reach the medical level, and the uniformity of the discharge of the melt-blown die is very high. The uniformity of the die depends on the design of the die, but the design is difficult." Li Pucha explained the technology to the reporter. difficulty. Through this big test, Jingcheng Times Group deeply realized that only high-quality products can come in handy at a critical juncture, which also strengthened their determination to continue to develop in the direction of high quality.
When melt-blown cloth was "difficult to find", Zhejiang Zhaohui Filtration Technology Co., Ltd. developed new epidemic prevention materials to replace melt-blown cloth. On March 3, Zhejiang held the first conference on the recommendation of new epidemic prevention materials hosted by the Provincial Department of Economics and Information Technology. It was made clear at the meeting that the nano-scale film material developed by Zhaohui is a new type of reusable epidemic prevention mask material, which is a low-resistance, high-efficiency and easy-to-clean film composite material, which can be optimized to replace the key material "melt-blown cloth" for mask production. To alleviate the shortage of materials for mask production.
"This material can be used for simple high-temperature disinfection, cooking and disinfection, and repeated use more than 10 times. Based on the company's current planned daily output of 70,000 square meters, it is equivalent to 17.5 million masks per day." The relevant person in charge of Zhaohui said that this research It is an opportunity for the future development of the enterprise.
"Our infrared temperature measurement chip is a single chip that can complete infrared signal amplification, analog-to-digital conversion, signal processing, transmission and display functions. The cost performance far exceeds similar manufacturers at home and abroad. Other companies need two or three chips to achieve our single The function of the chip. "In Luo Weishao's view, such a comparative advantage can make its enterprise far away.
Through the words of Ma Rende, the chairman of Hangzhou Haodeli Intelligent Technology Co., Ltd., he can also see that the opportunity is coming. He said: "During the epidemic, the company not only did not reduce production, but increased production. I also donated many anti-epidemic materials to the front line of anti-epidemic . "
Such stories are also staged throughout Zhejiang. Zhejiang's ability to respond quickly during the epidemic is due to its long-standing efforts in the manufacturing sector. Manufacturing has always been the foundation of Zhejiang's province and the foundation of a strong province, and it is also the main stage of world economic competition. Under the current situation, Zhejiang manufacturing enterprises are taking active actions to cope with the changes in globalization, build a new manufacturing pattern, and lay a solid foundation for building a global advanced manufacturing base.
