1 Die 2 Thread Automatic Thread Rolling Machine

Our 1 Die 2 Thread Thread Rolling Machine is a high-efficiency, high-precision cold forming equipment specially engineered for mass production of standard and non-standard bolts, screws, studs, threaded rods and other fasteners. Adopting the industry-leading 1D2T flat die rolling process, this machine forms two complete threads in a single pass, doubling production efficiency compared with traditional single-thread rolling machines while maintaining superior thread quality.

Core Competitive Advantages

• Industry-Leading Efficiency: The optimized cam transmission system delivers a stable production speed of up to 180 pieces per minute, significantly shortening your production cycle and reducing unit cost.
• Superior Thread Quality: Precision-ground rolling dies produce threads with smooth surface finish, high dimensional accuracy and excellent tensile strength, fully meeting DIN, ANSI, JIS and ISO international standards.
• Ultra-Stable Operation: Heavy-duty cast iron frame provides exceptional rigidity and vibration absorption, ensuring consistent performance even in 24-hour continuous industrial production environments.
• Low Maintenance Design: Modular structure and wear-resistant components minimize downtime and maintenance costs. Die replacement can be completed in less than 10 minutes by a single operator.
• Wide Versatility: Compatible with various metal materials and thread profiles. We offer customized solutions for special thread shapes, feeding systems and voltage requirements.

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.
