DC53 rolling dies with special process for high tensile bolts

This special process DC53 thread rolling die is mainly used to roll wind turbine fasteners, hexagonal bolts, high-strength anchor bolts and so on. Because the hardness of these workpieces is relatively high, ordinary thread rolling dies will wear quickly when processing these workpieces,so the service life is not long, so we developed this kind of thread rolling dies with special technology.

These workpieces are used in increasingly common wind power generation, hydropower generation, nuclear power generation, solar power generation, auto parts industry, tunnels, bridges, building construction and so on.
