On March 1st, the new material in the Changsha High-tech Zone is packing its own products. The newly built factory is still under renovation. The same product of a coiled cable tray is continuously shipped out of the temporary packaging workshop and sent to all parts of the country. A wire-sized diamond wire is wound around the cable drum.
Tens of thousands of teeth are attached to the snail's small tongue. These diamond wires are attached with numerous tiny diamond particles, which can easily cut hard and brittle materials such as hard sapphire and solar crystal silicon.
In the field of electronic information and new energy, accurate cutting and curve cutting of hard and brittle materials such as sapphire, silicon and magnetic materials have always been an industry problem. Diamond wire cutting technology not only solves the environmental problems of traditional methods such as mortar cutting, but also has higher efficiency and lower cost. In foreign countries, only Japan, the United States and other companies have mastered the relevant core technologies.
After more than two years of research and development, relying on its own technological breakthroughs, the new material became the first company in China to master the diamond wire R&D and production technology and put it into production on a large scale, successfully breaking the technological monopoly of Japanese and American foreign companies. Take the processing of solar wafers as an example: after processing diamond wire cutting, the processing enterprise has increased the efficiency by more than 2.5 times compared with the traditional cutting efficiency; the cost has plummeted by more than 30%.
Duan Zhiming, chairman and general manager of Muller New Materials, said that the birth of domestic diamond wire is driving technological changes in the field of hard and brittle materials cutting. The new market is opening up. It is expected that the market demand for domestic diamond wire will be in the next 3-5 years. More than 10 billion yuan.
"In the beginning of the year, we have received orders that have doubled the same period of last year. We are also trying our best to expand production capacity and improve the efficiency of business management," said Duan Zhiming.
At present, well-known companies such as Lansi Technology and Longji, which are well-known by Hunan people, have cooperated with Muller New Materials for many years. The company's diamond wire production and sales volume and market share ranks among the top in the domestic industry. The products have been exported to Taiwan, Russia, South Korea, etc., covering more than 100 well-known photovoltaic and sapphire processing enterprises around the world.
In the manufacturing industry, every step of material science breakthroughs brings about changes in the products and production methods of related segments. The new material of Muller is the representative of the rapid rise of emerging enterprises in Hunan's new materials industry.
At the end of the "Twelfth Five-Year Plan", Hunan Province has formed a new material industry system from research and development to production, production, study and research, and complete categories. In 2016, the province's total output value of new materials reached 398.945 billion yuan, an increase of 8.5% year-on-year; the new material industry added value of 102.047 billion yuan, an increase of 9.4%.
Chen Jun, director of the Raw Materials Industry Division of the Hunan Provincial Economic and Information Technology Commission, believes that Hunan is a non-ferrous metal province, a non-ferrous metal home, and has a natural soil for research and development of new materials and the growth of new materials companies.
“The new materials industry is closely related to non-ferrous metal processing, metallurgy, chemical industry, building materials and other fields. It is necessary to prevent low-level industrial expansion and duplication, and encourage market players to promote the development of new materials industry through transformation and upgrading and innovation drive.” Chen Jun said .
