This M5 flat die thread rolling machine is professional cold forming equipment designed for high-volume production of small threaded fasteners such as machine screws, self-tapping screws and miniature bolts. It forms complete external threads by extruding metal blanks between two reciprocating flat thread dies, with no cutting chips generated in the process. Compared with traditional thread cutting, it delivers higher thread strength, better surface finish and over 95% material utilization.
The machine features a one-piece cast iron body with outstanding vibration absorption capacity, which guarantees stable operation at full speed and maintains long-term machining precision. It comes standard with an automatic vibratory feeding system that enables continuous unattended production, with a maximum output of 200 pieces per minute, effectively reducing labor input and improving production efficiency.
It is compatible with a wide range of materials including carbon steel, stainless steel, copper, aluminum and alloy steel. The finished threads have accurate pitch, smooth surface and excellent fatigue resistance, making it ideal for fastener factories, electronic hardware manufacturers and automotive parts suppliers. It can be paired with an M5 cold heading machine to form a complete small screw production line, providing a turnkey solution for fastener manufacturing.
This multi-station cold heading machine is fully automatic cold forging equipment for fastener manufacturing. It can complete multiple forming processes in one machine, greatly improving production efficiency and reducing labor cost.

MoreThis two-axis hydraulic thread rolling machine is a professional cold-forming equipment designed for mass production of high-precision threaded fasteners and shaft workpieces. By driving two parallel rolling dies to rotate synchronously, it extrudes the metal blank at room temperature to form complete thread profiles, without cutting off the metal grain structure.
Compared with traditional thread cutting, cold thread rolling significantly improves the surface hardness, fatigue resistance and shear strength of finished threads, while achieving over 99% material utilization and 5-8 times higher production efficiency. The machine supports both infeed rolling for short threads and throughfeed rolling for unlimited-length workpieces, and can also be used for knurling, serration forming and straightening processes by replacing die sets.
The machine body adopts integral cast iron structure with excellent vibration damping performance, ensuring stable operation under high pressure and long-term accuracy retention. The hydraulic feed system is equipped with pressure stabilizing valve and overflow protection, providing smooth and controllable rolling force. The independent spindle tilt adjustment mechanism allows precise setting of thread helix angle, suitable for metric, inch, trapezoidal and special thread profiles.
It is widely used in fastener manufacturing, automotive parts, construction hardware, mechanical transmission and other industries, processing carbon steel, alloy steel, stainless steel, copper and aluminum materials. The whole machine is equipped with overload protection and emergency stop device, and complies with international safety operation standards.

MoreThis high-performance automatic thread rolling machine adopts advanced cold forming technology to produce precision threads on bolts, screws, studs and other fastener workpieces without chip removal. Compared with traditional thread cutting, the cold rolling process rearranges the metal grain structure, improving thread tensile strength by over 20% and delivering a mirror-like surface finish.
Equipped with a high-rigidity cast iron body and precision-ground spindle system, the machine maintains stable rolling force under long-term high-speed operation, ensuring consistent pitch diameter accuracy across batch production. The unique feeding mechanism eliminates jamming and reduces die wear, while the centralized lubrication system extends service life and lowers maintenance costs.
Suitable for mass production in fastener manufacturing, automotive parts, construction hardware and mechanical processing industries, it supports processing of metric, UNC, UNF and ACME thread profiles. The machine features simple setup, quick die change and low energy consumption, helping customers significantly improve production efficiency and reduce per-unit manufacturing costs.

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.
