Leading Chinese fastener equipment dealers!
Harbin Rainbow Technology Co., Ltd.
This CY series high-speed automatic flat die thread rolling machine, manufactured by Harbin Rainbow Technology, is professional cold forming equipment dedicated to mass production of threaded fasteners including screws, bolts, studs and rivets. It adopts chipless cold rolling technology to form threads through metal plastic deformation, which delivers higher thread strength, better surface finish and more stable dimensional accuracy than traditional thread cutting process, serving as core supporting equipment for complete fastener production lines.
High-Efficiency Automatic Production Equipped with a vibratory automatic feeding system and precision crankshaft transmission structure, the machine realizes continuous unmanned operation with a maximum speed of 320 pieces per minute. One operator can manage multiple machines simultaneously, effectively reducing labor cost and lifting overall factory output.
Premium Forming Precision Fitted with precision-ground alloy thread dies and optimized pressure structure, it produces smooth, burr-free threads with consistent pitch and dimensional accuracy. The cold-formed threads feature denser metal fiber structure and better wear resistance, fully complying with international mainstream thread standards.
Heavy-Duty Durable Structure The cast iron main frame undergoes stress relief treatment to ensure excellent rigidity and vibration resistance. The heavy-duty transmission system is matched with an automatic centralized lubrication system, guaranteeing low noise, low wear and stable performance during long-term high-speed operation.
Easy Operation & Maintenance The intuitive control panel lowers the technical threshold for operators. Thread die replacement and specification adjustment are simple and fast, enabling flexible switching between multi-specification orders and reducing equipment downtime.
Widely applied in fastener manufacturing, hardware processing, automotive parts, construction hardware and electronics industries, suitable for mass production of various standard and non-standard threaded workpieces. We provide full after-sales support including English operation manual, installation & debugging guidance, 12-month warranty, lifelong technical consultation and global spare parts supply. Customized solutions for special specifications and production line matching are available on demand.

Harbin Rainbow Technology designs and manufactures a full range of high-speed automatic flat die thread rolling machines for the global fastener industry. As core supporting equipment paired with cold heading machines in screw and bolt production lines, the CY series machines form threads through cold plastic deformation of metal workpieces, replacing traditional thread cutting process with superior thread density, wear resistance and dimensional accuracy.
With over 30 years of experience in the fastener equipment industry, Harbin Rainbow Technology provides one-stop production solutions including cold heading machines, wire drawing equipment and electroplating lines. All thread rolling machines are CE certified, backed by 12 months warranty, English operation guidance and lifelong after-sales technical support, and have been widely adopted by fastener manufacturers across the world.
