CY Series High-Speed Thread Rolling Machine: Empowering Global Fastener Manufacturers with Precision & Efficient Production

Against the backdrop of rapid expansion in global automotive manufacturing, new energy infrastructure, construction engineering and industrial equipment sectors, the market demand for high-strength, high-precision fasteners continues to rise. As a core process in fastener production, thread forming quality directly determines the mechanical performance and service life of end products. Rainbow Technology, a leading supplier of fastener equipment in China, has launched its upgraded CY series fully automatic thread rolling machine, providing a high-efficiency, low-consumption production solution for fastener manufacturers worldwide.

1. Advanced Cold Rolling Process: Subverting Traditional Cutting Thread Production

Different from the traditional thread cutting process that removes material by cutting tools, the CY series thread rolling machine adopts cold plastic forming technology. Under the precise extrusion of two high-hardness thread rolling dies, the metal workpiece undergoes plastic deformation to form a complete thread profile.

Compared with the cutting process, cold thread rolling has significant technical advantages:

• Higher material utilization: No chip generation, material saving rate exceeds 15%, which greatly reduces raw material cost in mass production.

• Stronger thread mechanical properties: The metal fiber flow line is continuously distributed along the thread profile, and the tensile strength and fatigue resistance of the thread are increased by more than 20% compared with cut threads.

• Better surface quality: The rolled thread surface obtains work hardening effect, with surface roughness up to Ra0.8, which effectively reduces wear during assembly.

• Faster production efficiency: The machine can realize continuous feeding and rolling, and the production speed can reach up to 200 pieces per minute for small-size fasteners, which is 3–5 times that of ordinary tapping equipment.

2. Heavy-Duty Structure & Precision Control: Stable Operation for Long-Term Mass Production

The CY series thread rolling machine is built with a heavy-duty integral cast iron machine body, which has high rigidity and shock absorption performance. It maintains a low-vibration state even under 24-hour continuous high-speed operation, effectively ensuring long-term dimensional stability of threads.

Core configuration highlights

• High-precision transmission system: Equipped with a hardened gear reducer and precision crank linkage mechanism, with high transmission efficiency and low operation noise.

• Intelligent control unit: Built-in proximity sensor and counter display unit, which can realize real-time monitoring of production quantity, equipment running status and fault alarm, facilitating production statistics and equipment maintenance.

• Quick die change design: The die clamping mechanism adopts an adjustable structure, which can complete die replacement and debugging within 15 minutes, and flexibly responds to production switching of different thread specifications.

• Wide processing range: It supports processing of bolts, screws, studs and other workpieces with thread diameters from M1.6 to M24, covering most mainstream fastener specifications on the market, and can adapt to the production of standard and non-standard special-shaped threads.

3. Seamless Whole-Line Integration: Building a Fully Automated Fastener Production Line

As an indispensable post-process equipment in the fastener manufacturing chain, the CY series thread rolling machine can be seamlessly connected with upstream cold heading machines, automatic feeding machines, and downstream heat treatment furnaces, electroplating lines and testing equipment, to form a fully automated fastener production line from raw material wire to finished products.

Through modular design and signal interconnection, the whole line realizes synchronous operation of all processes, reduces manual handling and intermediate transfer links, and improves overall production efficiency by more than 30%. For large-scale fastener manufacturing enterprises, this integrated solution can effectively reduce labor costs, lower product defect rates, and realize lean production management.

4. Wide Application Scenarios & Global Market Verification

At present, CY series thread rolling machines have been widely used in various fastener production scenarios around the world:

• Standard fastener production: High-volume manufacturing of hex bolts, machine screws, self-tapping screws and other standard parts for the hardware, construction and furniture industries.

• High-strength fastener production: Processing of automotive bolts, chassis fasteners and wind power bolts, meeting the requirements of high precision and high fatigue strength.

• Non-standard custom fasteners: Supporting customized production of special-shaped threads, step screws and special workpieces according to customer drawings.

The equipment has been successfully deployed in production bases in the Middle East, Southeast Asia, Eastern Europe and other regions, and has been widely recognized by customers for its stable performance and low failure rate.
