China’s high-precision cold drawn tube, the first to be widely used in the coal industry, and now it has been extended to the manufacturing engineering industry, oil, cylinder, cylinder, and piston rod.

Drawing quality, efficiency, more and more high, production is also increasing, with the precision cold drawn technology continues to improve, technologies and products of high precision cold drawn features become more prominent, large and useful high-precision cold drawn completely replace the traditional cutting potential, a coal mine in China has been using the tube drawing to do a single hydraulic cylinder pillar for the coalface Earthly care, achieved good results. The fuel tank of a pillar of Britain, Germany, and other countries in underground coal mine monomer, all made of the cold drawing process.

High-precision cold drawn tube with high dimensional accuracy and surface quality, fibrous tissue is small, excellent machining and mechanical properties of cold drawn technology need further development and improvement.
