Trimetal Composite Contact Cold Header can make six different metals be compounded together under cold state to produce composite contacts according to the technique requirements. Its working process includes the following steps: Sending two different kinds of metal wire into the machine firstly, transmitting them into the mould after being cut off. Then by two times upsetting process, the two kinds of metal become the composite contacts. Finally, the products retreat from the mould and enter into the finished product box.

Product Overview

Our two-axis thread rolling machine is a professional heavy-duty cold forming equipment dedicated to high-precision and high-strength thread processing. Adopting advanced two-die synchronous extrusion technology, it forms threads through cold plastic deformation of metal without cutting chips. Compared with traditional thread cutting process, it greatly improves the surface finish, dimensional accuracy, tensile strength and fatigue resistance of finished threads, and is widely used in manufacturing high-grade fasteners and structural parts.

Core Advantages

1. High Precision & Consistent Forming Quality The two-die synchronous rolling structure ensures uniform and stable extrusion force, producing full, smooth and standard thread profile with high pitch accuracy. Batch processed workpieces have excellent consistency, which fully meets the quality requirements of high-strength standard parts and precision mechanical components.
2. Heavy-Duty Rigid Structure, Long Service Life The whole machine adopts integral cast iron fuselage with excellent rigidity and shock absorption performance. It maintains stable operation with low vibration and low noise even under long-time heavy load working conditions, effectively reducing equipment wear and prolonging the service life of both the machine body and thread dies.
3. Intelligent Control, Easy to Operate Equipped with PLC control system and intuitive touch screen interface, operators can easily set and adjust rolling pressure, feeding stroke and production rhythm. Built-in fault self-diagnosis and parameter memory function reduce operation difficulty and downtime, and help improve overall production efficiency.
4. Strong Material & Process Adaptability It is suitable for thread processing of various metal materials including carbon steel, alloy steel, stainless steel, copper and aluminum. By replacing different thread dies, the machine can produce metric threads, inch threads, trapezoidal threads and knurling patterns, satisfying diversified demands for both standard and customized non-standard workpieces.

Application Fields

This two-die thread rolling machine is widely applied in fastener manufacturing, automobile parts, construction machinery, bridge hardware, electric power fittings and other industries. It is an ideal choice for producing high-strength hex bolts, stud bolts, threaded rods, anchor bolts and other high-requirement threaded products.

Service & Support

We provide a 12-month whole-machine warranty, lifelong technical consultation and original spare parts supply. Every machine undergoes strict no-load and load testing before delivery. We offer free remote guidance for installation, debugging and operator training, and on-site service by professional technicians is also available upon request.
