The 160 kilogram sapphire single crystal furnace will be produced in Nanjing

The new Apple product Iwatch of the south newspaper is equipped with a sapphire screen to become a big selling point. The hardness of sapphire is second only to diamonds, and the artificial sapphire single crystal is widely used in the field of LED and smart phones. Nanjing Jing Sheng Energy Equipment Co., Ltd. looks at this market demand, absorbs top international technical talents, and develops the first 85 kilogram sapphire single crystal single crystal furnace in China, which greatly improves the efficiency of sapphire crystal growth.

Li Hui, the general manager of Nanjing Jing Sheng Energy Equipment Co., Ltd., was engaged in equipment technology service when he started his business in 2011. "Domestic enterprises want to buy sapphire single crystal furnace abroad, we provide business consulting and equipment technology assessment." Li Hui said that contact with the industry found that foreign equipment is very expensive, but some of the use effect is not very good. "One of the most expensive monocrystalline furnaces for foreign companies will sell more than 80 million dollars and also set up a minimum purchase line, such as less than 48." Li Hui said that some enterprises bite the teeth to buy, but the actual production rate of crystal finished 40% can not reach. According to his contact, four or five enterprises in China lost more than 200 million dollars in 1 to 2 years.

Can you develop a single crystal furnace with lower cost and higher efficiency? With this idea, Li Hui set up Nanjing Jing Sheng Energy Equipment Co., Ltd. in 2012, and then set up an overseas R & D center in New York, USA, and absorbed 4 well-known experts in the related fields. "New York is a well-known enterprise in the field of crystal materials and university R & D institutions, and their research is in the world's leading level. The R & D center is located there, which can be close to the cutting-edge technology and absorb and digest. Li Hui said that the US R & D center experts have transplanted the most advanced thermal field design and crystal growth control technology into the crystal growth of sapphire material and successfully developed a 85 kilogram single crystal furnace. Using this furnace, a crystal with 85 kilograms weight can be grown at one time. "In 2013, the 35 kilogram single crystal furnace was widely used in China, and we were the first domestic enterprise to produce 85 kilograms." According to Li Hui, the price has been nearly half reduced compared with the foreign products of the same kind.

After two years, crystal Sheng energy has sold 100 sets of 85 kilogram monocrystalline monocrystalline furnaces. The top five LED chip manufacturers in China are using the equipment to produce sapphire crystals for LED substrate materials. Through continuous technological innovation, the 85 kilogram single crystal furnace has added a lot of advantages: the use of thermal field temperature gradient control technology to shorten the crystal growth cycle from the original 20 days to 15 - 16 days; the use of new materials to improve the thermal insulation effect, equipment operation is 20% and so on than ordinary products.

Today, the greater demand for sapphire crystals comes from smartphones than LED substrate materials. "Take the example of the apple mobile phone, now the touch key and the camera glass are all using sapphire crystal. If the cell phone screen will also use sapphire crystal in the future, the output will increase greatly. Li Hui told reporters that two years ago, the Apple Corp had talked to crystal litre energy, hoping to supply them with a larger capacity single crystal furnace. Last year, the 125 kilogram grade single crystal furnace has been successfully developed, and 15 units have been sold in China for the first time. Li Hui also revealed that soon after, the company's 160 kilogram super large - capacity single crystal furnace could be out of the prototype. "If a 160 kilogram single crystal furnace can produce a product, it will be able to establish a long-term cooperation with the Apple Corp." Li Hui said.
