Dongjing Optoelectronics won the Apple iwatch order to develop and produce sapphire screen

A few days ago, the author went to Huangshanjing Optoelectronics Co., Ltd., and the general manager Zhang Huixuan was in the production workshop to check the color of a batch of new sapphire crystals in the crystal growth furnace. The products will be sent to Jiangsu, Shenzhen and other places.

Huangshanjing Optoelectronics Technology Co., Ltd. is a large-scale industrial project introduced in Tunxi District in 2011. It is a wholly-owned subsidiary of the listed company Zhejiang Dongjing Electronics Co., Ltd. It is also a collection of LED product development, production, sales and engineering services. In one of the high-tech enterprises, specializing in the production of high-quality sapphire crystals, sapphire optical components, LED sapphire flat substrate and graphic substrate production and sales.

Following the direction of Zhang Hui's finger selection, the author saw a transparent glass body with a bucket of water. "You don't look big, but the density is high. The hardness is in the style of the motorcycle, which is second only to the diamond. This one has a weight of 120 pounds. The market value is around 200,000 yuan." Zhang Huixuan said. This crystal is the first process of Huangshanjing Optoelectronics Co., Ltd. products.

“The furnace cleaning, charging, chemical, seeding, annealing, a growth cycle takes about 15 days. If the debugging is not good, the crystal is prone to cracks, then the crystal is useless and must be returned to the furnace.” The company is responsible for production. Technical workers, regardless of day or night, should check the curve according to the weight change of the crystal to fine-tune the equipment to ensure the best condition.

In addition to 111 sets of 45KG and 60KG crystal growth furnaces imported from abroad, the company independently developed 85KG grade crystal growth furnaces last year. It has independent intellectual property rights and has mastered many core patents in the production process. The crystallization cost is higher than that of the domestic industry. It should be a lot lower. Recently, the company has partnered with Apple's Chinese manufacturers to create screens and other spare parts for Apple's latest iwatch smartwatch.

At present, the company's other project LED lighting workshop has begun production, with an annual output of 300,000 LED chip packages and 4 LED lighting lines running smoothly. In addition, the multi-functional test workshop with multiple functions is currently undergoing renovation and decoration. After completion, it will be used for performance testing of sapphire crystals, research and development of related equipment, etc. After the completion of production, the output value of the enterprise will reach 700 million yuan. .
