6-Station & 7-Station Nut Former — Professional Standard Cold Forming Machine for Nut Production

Harbin Rainbow Technology Co., Ltd. specializes in the R&D and production of standard multi-station nut forming equipment, providing high-quality 6-station and 7-station nut formers for global fastener manufacturers. This series of standard nut cold heading machines is specially used for one-time cold forming of various nut blanks, including hex nuts, flange nuts, weld nuts and conventional non-standard nuts, with stable operation and wide industry applicability.

The 6-station and 7-station progressive forming structure enables the equipment to complete multiple processes such as wire cutting, piercing, upsetting and shaping in one continuous cycle. The progressive cold forming process ensures continuous metal fiber flow of nut products, stable internal structure and excellent mechanical properties, meeting the quality requirements of construction, machinery, automobile and general industrial fasteners.

The whole machine adopts rigid reinforced body design to cope with high-frequency and high-pressure cold forming operation. After mechanical calibration and parameter setting, the equipment can realize consistent batch molding of nuts with stable size and qualified finished product rate. It can be used in supporting connection with tapping machines, heat treatment mesh belt furnaces and automatic sorting equipment to form a fully automatic nut production line, realizing streamlined production from raw materials to finished nuts.

Focusing on the practicality and durability of industrial equipment, Harbin Rainbow Technology provides customers with whole-process services including equipment installation, mechanical debugging, operation training and after-sales maintenance. According to customers’ nut specifications, materials and output requirements, we provide targeted equipment use and die matching solutions to ensure stable production benefits for fastener factories.
