China's first self-developed digital disc injection molding machine developed by Guangdong Kenli Machine Co., Ltd. has passed expert appraisal. This scientific and technological achievement means that China's long history of relying on imported equipment to process optical discs has also ended, and it also marks a new member of the "disc club" monopolized by several developed countries.
According to a report in the Workers Daily on August 21, according to experts' forecasts, the demand for Chinese optical discs is expected to increase by more than 30% in the next 20 years. The annual demand for domestic digital optical disc production lines ranges from 100 to 200, and if they are imported, the sales of RMB 8,000 to 1 billion will be converted. At present, China has more than 60 CD-ROM replication companies and more than 300 production lines, but all of them are import production lines. An ordinary CD, VCD production line, China's import price of 3 million yuan, DVD-R production line is up to 10 million yuan more expensive price. At present, the international market for the production of digital compact disc production line injection molding machine mainly by the German KM, the Netherlands NESTAL, Japan's Sumitomo, Sweden TOOLEX and other very few companies are occupied. According to experts, CDs closely related to people's working life are actually plastic injection molding presses called polycarbonates. Even the micro signal depth of the surface is 0.11 μm. Only the tiny groove marks of 1/700 of the hair are injected. Injected and molded by the machine, the colorful light on the surface of the optical disc is caused by reflection of light by a layer of aluminum film. In order to ensure that these signals are not missed and lost in the pressing, extremely high requirements are placed on the injection molding machine, the mold and the production line. Due to the ultra-precision requirements of the injection molded compact discs, many manufacturers have taken the lead and the optical disc production line has become a patent product for a few industrial powerhouses.
Foreign media generally believe that China's development of optical disc injection molding machine at least 10 years, and this prediction was broken by a private technology company in Shunde, Guangdong Province.
In 1998, the scientific and technological research team headed by Guangdong Wanli Machinery Co., Ltd., general manager and national expert Huang Buming as the project leader, began to apply the obtained invention patent to research and develop digital disc injection molding machines, and started a large number of scientific research experiments and obtained a series of Precision products molding technology. In 2001, the digital disc injection molding machine was included in the national key new product project. At the same time, a domestically-produced optical disc production line consisting of several institutes and enterprises was established to jointly tackle the problem. In April 2003, an expert from the National CD-ROM Center of Tsinghua University examined the performance of online and offline products on CD-ROM production lines. The CD, VCD, and CD-R disc specifications met all the relevant international standards, especially the CD-ROM injection molding machine. The self-adaptation of the clamping force and injection pressure, the realization of self-positioning of the mold and the precision injection compression function are more innovative than those of foreign products.
