Multi-Station Cold Heading Machine & Bolt Heading Machine — Standard Reliable Fastener Forming Equipment

Harbin Rainbow Technology Co., Ltd. offers high-performance standard cold heading machines and bolt heading machines, core foundational equipment for mass production of standard bolts, special-shaped bolts, and screw blanks in the fastener manufacturing industry. Designed for industrial-grade continuous cold forming operation, our standard bolt forming equipment focuses on stable mechanical performance, durable structure, and consistent product molding quality, catering to the mainstream production needs of global fastener factories.

Different from traditional metal cutting processing, cold heading technology realizes room-temperature plastic deformation of metal wire rods, retaining complete metal grain structure and effectively improving the mechanical strength and structural stability of finished bolts. Adopting heavy-duty integral cast frame and precision transmission structure, our standard cold heading machines reduce vibration and deformation during long-term high-load operation, ensuring uniform molding size of bolt blanks in batch production.

The equipment is suitable for processing carbon steel, alloy steel and stainless steel workpieces, covering conventional specifications of various industrial bolts and screws. It can be perfectly connected with downstream thread rolling machines, heat treatment equipment and sorting equipment to form a complete automated bolt production line. With simple and practical operation logic and low daily maintenance cost, the machine is very suitable for medium and large-scale fastener mass production.

Harbin Rainbow Technology adheres to practical and reliable equipment design concepts. For different customer production needs, we provide professional mechanical debugging guidance, die matching schemes and after-sales technical support, helping customers achieve stable and efficient bolt cold forming production.
