A 5G filter product, the whole process involves 113 processes and more than 40 parts. Our current self-made rate of parts is more than 95%. It is the only one in the world that can realize the dual-line production of 5G metal and ceramic filters and has a full industrial chain. "
A few days ago, He Gaobiao, vice president of SZDF Electronic Technology Group, said in an interview with Chinese media reporters that in 2020, the number of 5G base stations in China will account for more than half of the global number, and the annual market demand for domestic filters will exceed 2 million sets. For SZDF, it is an unprecedented opportunity and challenge.
Ten years ago, SZDF acquired 7 leading filter technology companies in Europe and the United States by seizing opportunities and independent innovation, breaking through the bottleneck of key filter manufacturing equipment such as special CNC machine tools, making the filter manufacturing process no longer used abroad. Stuck neck".
Reduce costs and lead industry progress
He Gaobiao clearly remembered that when he first entered the filter industry in 2004, the price of a filter was as low as 8,000 yuan, as high as 15,000 yuan, and it was produced by only a few foreign companies such as Siemens and Motorola. Most of the products were customized. Can't form mass production. Now, 16 years later, the cost of labor and materials in the filter industry has doubled, but the price of a product has dropped to about 800 yuan. Standardized and large-scale production has already been realized, and these are inseparable from the contribution of SZDF.
In a four-story factory building in SZDF, the reporter saw a complete set of surface treatment processes for filters from oxidation to electroplating to powder spraying to achieve seamless connection between floors. There is the only fully automatic surface treatment production line in the province. The neatly arranged spray guns rotate like a stream. The scale, standardization and automation are fully demonstrated in this plant. "These processes are very standardized now, but the entire industry was not like this before." He Gaobiao said that it was SZDF that brought the lean production of filters to the road of standardization.
