In the field of cold forging, thread rolling dies are still the sharp weapon to make various threads. Its applications contain types of threads for automobile, motorcycle, bike; R-shape steel bar and scaffold pipes for architecture; components and parts for mechanical industry and hardware and handtool industry. Therefore, it functions very well by applying to a wide selection of machine component and parts.
The quality of thread rolling die not only affects the speed, productivity and efficiency of thread production, but also has a great influence on product itself.
Our thread rolling dies use the high class cold forging alloy tool steel that is suitable for thread rollers.
With the experienced and professional process of vacuum heat, it features uniform hardness and high stability. Finally, our professional and strict manufacturing process makes its concentricity and verticality best precised.
The types of our thread rolling dies and thread include Metric (M), BSW (Whitworth), BS , PT , PS , UNC , UNF , NPT , NPS , trapezoid thread (GB) , TM (M) , raised R-shape , Concave R-shape , forming , ACME , sewing machine (SM) , bicycle (BC)... . In addition, any request of special specification, thread shape, pitch and teeth is welcome.
