GRINM is the founder of Chinese spinning technology. The current domestic main equipments and technologies are established on the basis of the GRINM’s equipments and technologies. Currently, GRINM not only process and produce the tube barrel and simple revolver the diameter of 60 ~ 2200 mm, monomer length of up to 3000 mm, and wall thickness of 0.5 ~ 40 mm, but also providing volume production various alloy thin-walled tube with High-precision and High-difficulty. These Spinning alloys include the large diameter cylinder which cannot be produced by conventional means such as titanium alloy, aluminum alloy, copper alloy, Ni-based high-temperature alloy. The products have many features of good surface quality, high polishing, dimension precision, wide range and low cost.
