Nanjing crystal energy 160 kg sapphire single crystal furnace will sample

Southern news network new Apple Iwatch equipped with sapphire screen, became a major selling point. Sapphire hardness second only to diamond, artificial sapphire single crystal in the field of LED and smart phones are widely used. Nanjing Jing l Energy Equipment Co. Ltd. aimed at the market demand, to attract international top technical talent, developed China's first 85 kg sapphire single crystal furnace, greatly improving the efficiency of sapphire crystal growth.

Li Hui, general manager of Nanjing crystal energy equipment Co., Ltd. in 2011 to start a business, is engaged in equipment and technical services. "Domestic enterprises to buy foreign sapphire single crystal furnace, we provide business consulting and equipment technology assessment. Li Hui said that after contact with the industry found that foreign equipment is very expensive, but some use is not very good. One of the most expensive single crystal furnace of foreign companies to sell 80 tens of thousands of dollars, but also set the minimum procurement line, such as less than 48 units do not sell. Li Hui said that some companies bite to buy it, but the actual production rate of 40% of the crystal products are not up to. According to his contact at that time, there are four or five domestic enterprises in the 1 - 2 years on the loss of $more than 200 million.

Can you develop a lower cost, more efficient single crystal furnace? With this idea, Li Hui was established in 2012, Nanjing crystal energy equipment Co., Ltd., and then set up an overseas R & D center in New York, the United States to attract 4 well-known experts in related fields. "New York is a leading company in the field of crystal materials and research and development institutions in the world. The R & D center is located there, can be close to the forefront of technology and absorption. Li Hui said that the United States R & D center experts to the most advanced thermal field design and crystal growth control technology, organically transplanted to sapphire crystal growth, and successfully developed a 85 kg class single crystal furnace. The furnace can produce 85 kilograms of crystal at a time. "In 2013, the domestic use of the 35 kg class single crystal furnace, we are the first to produce a domestic enterprise of 85 kg class. Li Hui said, compared with similar foreign products, the price has been reduced by nearly half.

Two years down, crystal energy has sold 85 kg class single crystal furnace of 100 units. The country's top five LED chip manufacturers are using the device, the production of sapphire material for LED substrate material. Through continuous technological innovation, the current level of 85 kilograms of crystal furnace and add a lot of advantages: the use of the temperature gradient control technology, the crystal growth cycle is shortened from 20 days to 16 days, the original 15; the use of new materials to improve the insulation effect than ordinary products, equipment operation and saving 20% etc..

Today, compared with the LED substrate material, the greater demand for sapphire crystals from smart phones. "Apple phone, for example, now touch keys, camera glass are used sapphire crystal. If the future of the mobile phone screen also use sapphire crystal, the output will be greatly increased. Li Hui told reporters that two years ago, the Apple Corp went to talk about cooperation in crystal energy, hoping to provide them with a larger capacity of single crystal furnace. Through technical research, last year, crystal energy has successfully developed a 125 kg single crystal furnace, and in the country for the first time sold a total of 15 units. Li Hui also revealed that shortly after the company's 160 kg class large capacity single crystal furnace can be a prototype. If the 160 kg class single crystal furnace mass production, you can establish long-term cooperation with Apple Corp. Li Hui said.
