Escort for the quality of products

The company has fixed assets of more than 8000 million yuan and the existing equipment capacity is 0.3 billion million yuan. The forging production line of the company has 4000 tons of electronic screw press, 1250 tons of closed single point, 1250 tons of oil press, 630 tons of oil press, 800 reaming machine, 630 reaming machine, air hammer, free forging hammer, equipped with natural gas heating furnace, electric furnace and other equipment. The precision equipment in the machining workshop includes 30 CNC vertical lathes, 25 high-precision turn-milling compound inclined lathes and 25 vertical horizontal machining centers. Gear making equipment includes more than 70 CNC gear shaper machines such as YK5150D/YKC5150H, more than 50 CNC gear hobbing machines, 4 YK3180/160 rolling and milling compound machines, 1 YK8150 gear turning machine, 6 120-ton vertical Broaching machines and through-type ultrasonic spray cleaning machines; another CNC lathes, CNC drilling machines, grinding machines, milling machines, general car and other equipment a total of more than 200 units. 

The heat treatment workshop has box-type electric furnace, tempering furnace, medium frequency, high frequency, super audio quenching equipment and double-row push rod type gas carburizing furnace production line. The testing equipment includes three coordinate measuring machine, gear measuring center, magnetic flaw detection machine, tensile testing machine, etc., equipped with metallographic laboratory and physical and chemical laboratory, with perfect facilities and complete testing equipment to protect the quality of products.

The company has a sound product quality assurance system, has passed the IS09001:2015 certification; through the IATF16949:2016 certification, and through the ISO14000 environment system certification. Daxing Seiko always takes "integrity-based, quality first" as its business philosophy, strictly controls the technological process of each link, breaks through the problems of many construction machinery industries, and develops and manufactures various high-quality mechanical products. 

 Especially in the engineering machinery, axle wheel ring in the medium frequency heat treatment process can be comparable to foreign advanced technology, after years of practice and innovation, quenching out of the ring gear, no matter in the process quality, deformation, hardening layer depth and so on are in the forefront of the world, all aspects are better than carburizing, nitride process. The company is developing laser quenching process, will replace the nitride energy consumption, serious pollution and other issues.

In the wave of rapid industrial development, general manager Xu Gang will lead us to continue to innovate, abide by ingenuity, and make unremitting efforts to become a world-renowned machinery manufacturing enterprise.
