About the Company
The company is a machinery manufacturer based in Changchun (Jilin, China) specializing in research, development and manufacturing. The product portfolio comprises C-series friction welding machines in 37 sizes with more than 50 variants (0.3–1000 t), continuously driven, inertia and phase friction welding machines, rotary arc welding machines, X-series milling machines, CNC milling machines, vertical and horizontal machining centers, CNC gantry milling machines and CNC bed-type milling machines. In addition, the company develops and manufactures special-purpose machines, custom production lines, welding auxiliary equipment and non-standard equipment for nuclear industry reactors. The friction welding machines are used for joining similar and dissimilar metals (bimetal components), among other things in the automotive, tool, petroleum, geology, aerospace and defense industries. The Changchun plant has 259 production facilities, of which 186 are metal-cutting machines; annual capacity for conventional milling machines is 500 units. The company is a member of the milling machine section of the Chinese machine tool association and of the Chinese nuclear industry fast reactor alliance.
