Cold-drawing machine
With in the 1990 of the 20th century, China began research, and application cold pulled pipe technology yilai, cold pulled pipe technology has widely reference Yu monomer hydraulic cylinder tube and the engineering mechanical oil cylinder of manufacturing, cold pulled machine as cold pulled pipe of main processing equipment, it is for at room temperature Xia pulled business black and the nonferrous metals Rod material material and on hot, and extrusion zhihou of shortage tube for II times processing, is production small, precision, thin-walled, high mechanical performance pipe of main processing equipment.
