Advanced Technology of Harbin Rainbow 's Cold Forging Machines
Harbin Rainbow Technology Co., Ltd. is a leading manufacturer and supplier of cold forging equipment in China. The cold forging machines stand out with high rigidity, high efficiency, precision forming, energy saving and intelligent control, representing advanced technical standards in the fastener and metal forming industry.
The machine body is made of high-strength alloyed ductile iron, providing exceptional tensile strength, wear resistance and shock absorption. This stable structure ensures long-term precision under heavy-duty working conditions. The two-stage gear transmission delivers high efficiency and large torque, while the pneumatic clutch-brake system enables smooth starting, low power consumption and flexible operation modes—including inching, single stroke and continuous running.
Its cutting system adopts a guide-plate-driven cutter bar with linear force transmission, delivering stable cutting and excellent dynamic balance. The clamping mechanism supports 180° rotation and translation, greatly expanding forming possibilities for complex parts. With precision feeding and material straightening systems, the equipment achieves high dimensional accuracy and consistent product quality.
Our cold forging machines integrate digital control and stable performance, helping customers raise productivity, lower material waste and enhance product competitiveness. They are widely used in automotive, construction, machinery, aerospace and other fields, providing reliable and advanced solutions for high-speed precision cold forming.
