The big force in a small maskThe big force in a small mask
On January 25th, 8 million pieces; on February 29th, 116 million pieces ... In only 35 days, the daily output of Chinese masks increased by about 13.5 times.
From March 1st to April 4th, 3.86 billion pieces; from April 5th to April 30th, 23.94 billion pieces ... In just two months, China exported 27.8 billion masks, which is about Three times the total output of masks.

China has strong manufacturing capabilities. Adequate production space, perfect quality control system, massive high-quality talents, strong R & D and production system ... provide a solid foundation for mask production.
2nd Floor, Building B4, BYD Baolong Modern Industrial Park, Longgang District, Shenzhen, equivalent to 36 standard basketball courts, 100 mask production lines are running at high speed, and blue and white non-woven fabrics are laminated, curled, and folded , Flattening, seaming, welding ... It takes only 0.6 seconds to transform into a disposable medical mask.

This was once the 100,000-class dust-free workshop of BYD engaged in the production of mobile phone parts, but now it is the main workshop of the world's largest mask manufacturer.
Not only BYD, but also many manufacturing companies such as GAC, SAIC-GM-Wuling, Gree Electric, Youngor, etc. have switched production across borders, becoming the backbone of Chinese mask production.
"So many companies that had nothing to do with masks can quickly switch to masks, showing China's strong manufacturing capabilities." Zeng Qinghong, chairman of Guangzhou Automobile Group, said that China's manufacturing industry is rich in technology, management, quality control and supply chain management. Experience, sufficient talent reserve, and wide workshops provide a solid foundation for mask production.

Fan Weijian, an engineer of the Guangzhou Automotive Parts Process Engineering Department, clearly remembered that when assembling the first mask machine, the obscure mask ear straps were welded to become a "barrier." Only two or three pieces were welded, the welding head was stuck to the mask, and the entire production line had to be shut down immediately.
The key to ultrasonic welding is the welding head. Should we use 6 teeth or 7 teeth for the saw teeth on the weldable head? Should it be sharpened or slightly rounded? How much should the hardness of steel be controlled? There is no one to guide, but it can be explored based on professional experience. The research team was quickly established, and moved out of high-precision CNC machine tools for experiment. After four days and four nights of continuous shaft rotation, the best solution was finally found-0.4 mm by 1 mm diamond teeth, a slope of about 15 degrees, and the tip of the tooth must have a curvature , Tooth pin should be finely polished, forged and fired, and the hardness should be between 58 degrees and 60 degrees!

"China's industrial chain is interlinked and has a complete industrial system", which has become the consensus of the participating mask production enterprises. Although the mask is small, it covers a complex industrial chain, involving many basic industrial categories such as chemicals, textiles, materials, machinery, metallurgy, electronics, etc. It is also related to many basic processes such as material processing, machinery manufacturing, electrical control, and ultrasonic pressure welding. Masks cannot be made by "dropping the chain" at any link.
China has 41 industrial categories, 207 industrial intermediate categories, and 666 industrial subcategories, forming an independent and complete modern industrial system. It is the only country in the world that has all industrial categories in the United Nations industrial classification. During the epidemic prevention and control period, in the case of poor global logistics, various materials required for mask production and various parts required for mask machine production can be produced and purchased in China within a short period of time.
A complete industrial system not only provides a solid foundation for mask expansion, but also makes a huge contribution to global anti-epidemic. At present, China has provided medical supplies to 127 countries and 4 international organizations worldwide.
"Overseas orders have been arranged in October, and we have assisted in exporting to many countries." Jiao Na, Deputy Manager of the Export Business Department of Shandong Rizhao Sanqi Medical and Hygiene Products Co., Ltd., said that since the twelfth day of the twelfth lunar month, the lights on the factory floor have never been turned off. However, the cumulative production of about 300 million masks.
In this race against time, Sanqi is not fighting alone. In order to help Sanqi to resume production and expand production, Rizhao City set up a "work class" to settle in the company's on-site office, and the relevant departments also sent two special staff in the enterprise. What they lacked and helped to open up the industry chain. Sanqi Daily's production capacity quickly climbed to 3.5 million, which is five or six times higher than usual.
Looking at the whole country, in order to ensure the production and supply of masks, government departments at all levels and all walks of life are fighting in the first place. The whole country is playing chess and opening up the supply chain. "Our country has an institutional advantage, and everyone can work together in every position to have such a good effect." Said Sun Zhicheng, a member of the material security group of the Central Steering Group and the deputy director of the Social Development Department of the National Development and Reform Commission.
