Industry Background & Product Overview

Against the backdrop of accelerating global industrial upgrading, the fastener manufacturing industry is facing growing demands for higher product strength, tighter dimensional tolerance and lower unit production cost. As one of the core pieces of equipment in cold forming fastener production, thread rolling machines directly determine the final quality, production capacity and cost competitiveness of threaded products.

Our company has launched a new generation of high-performance thread rolling machines based on years of R&D accumulation and practical feedback from global customers. This series of equipment integrates precision machinery, automatic control and wear-resistant materials, which can not only meet the mass production of standard fasteners, but also adapt to the processing of various special-shaped threaded workpieces, providing reliable production support for fastener enterprises of all scales.

Heavy-Duty Structure & Stable Operation Guarantee

The whole machine adopts an integrated heavy-duty cast iron body with one-piece molding. After multiple aging treatment processes, the internal stress of the material is fully eliminated, ensuring high rigidity, shock resistance and long-term dimensional stability. Even under 24-hour continuous high-load working conditions, the equipment can maintain stable operation accuracy, effectively reducing the vibration and displacement generated during high-speed rolling, and extending the service life of the whole machine and wearing parts.

The transmission system uses a high-torque gearbox with hardened tooth surfaces, matched with a high-power brand motor, which provides strong and stable rolling power. The core rolling shaft is made of high-quality alloy steel, processed by forging, quenching and tempering, and precision grinding, with high strength and good wear resistance, which can withstand long-term high-pressure extrusion work without deformation.

Precision Control System & Processing Accuracy

This series of thread rolling machines is equipped with an advanced servo control system, which can precisely adjust rolling pressure, feeding speed and spindle speed through the human-machine interface. The parameter adjustment is intuitive and accurate, and it can be quickly switched according to different workpiece materials and thread specifications, reducing the debugging time during product replacement and improving the overall equipment utilization rate.

In terms of processing accuracy, the thread profile processed by cold rolling has a complete metal fiber flow line, and the surface hardness and wear resistance of the thread are significantly improved. The thread accuracy can stably reach Grade 6H, and the dimensional consistency of batch products is excellent. It fully meets the manufacturing standards of Grade 8.8, 10.9 and 12.9 high-strength fasteners, and can be widely used in high-demand fields such as automobile chassis, bridge construction, wind power equipment and aerospace components.

Core Advantages Over Traditional Thread Cutting

Compared with the traditional lathe thread cutting process, our thread rolling machine has obvious comprehensive advantages:

1. Higher material utilization: Cold rolling forming does not produce cutting chips, saving 15%-20% of raw materials, which significantly reduces material costs in large-scale production.

2. Higher production efficiency: The rolling speed is fast, and the production efficiency per unit time is 3-5 times that of ordinary turning processing. For standard small-specification screws, the output can reach hundreds of pieces per minute.

3. Better mechanical properties: The rolled thread surface produces work hardening effect, and the tensile strength and fatigue resistance of the thread are increased by more than 30% compared with cut threads, which improves the service life of the final product.

4. Lower labor cost: The equipment is easy to operate, and one worker can take charge of multiple machines at the same time, which reduces the dependence on skilled operators and lowers labor expenditure.

Wide Processing Adaptability & Rich Model Options

Our thread rolling machine series covers a variety of models, which can meet the thread processing of different specifications from M3 micro screws to M30 high-strength bolts. It is suitable for processing various metal materials including carbon steel, alloy steel, stainless steel, copper and aluminum, and can produce standard threads, trapezoidal threads, knurling and other different profiles.

In addition to standard cylindrical parts, the equipment can also process special workpieces such as step shafts, shoulder screws and self-tapping screws by replacing corresponding rolling dies and adjusting feeding mechanisms, which has strong product flexibility and can meet the diversified production needs of customers.

Automated Configuration & Whole Line Integration

To help customers build intelligent and unmanned production workshops, we can provide a full set of automated supporting solutions according to actual production needs, including automatic vibrating plate feeders, manipulator loading and unloading devices, online thread testing systems, automatic oiling devices and finished product sorting mechanisms.

These automated configurations can be seamlessly connected with our cold heading machines, thread rolling machines and other equipment to form a complete fastener production line from raw material feeding to finished product packaging, which greatly reduces manual intervention, improves production stability and reduces the rate of defective products.

Quality Control & Global After-Sales Service

Every thread rolling machine leaving the factory has undergone strict assembly debugging and full-load operation testing, and key components are traceable. We implement a complete quality management system in accordance with international standards to ensure that each equipment can reach the designed performance index.

For global customers, we provide comprehensive after-sales support including on-site installation guidance, operator skill training, regular return visit maintenance and long-term spare parts supply. Our professional technical team can respond to customer needs in a timely manner and provide remote or on-site troubleshooting services to ensure that the equipment is always in good operating condition.
