Large diameterHigh-precision spinning
              The GRINM is China's largest non-ferrous metal industry research and development institutions. It is one of the units which is the earliest engaged in research and development of large diameterHigh-precision spinning .
              The GRINM researched and developed large-diameter high-precision spinning partsat first in china.A hollow conical, cylindrical, semi-spherical and thin-walled pipe spinning precision products were successfully investigatived and produced .The products used in aerospace, nuclear energy, weapons and chemical industry. The GRINM has abundant of rich experience and theoretical knowledge of spinning technology. Large-diameter thin-walled and special-shaped pieces of products are produced.Spinning technology and theory are investigative.A number of research results received ministerial and national award. The GRINM contribute todevelop, study and produce military and civilian product. The GRINM can produce the diameter of 60 ~ 2000mm, the length of less than 4000mm, wall thickness of 0.4 ~ 10mm of the cylinder and the rotating body components, high-precision production of various difficult high-alloy thin-walled tube.
