A cold extrusion rebar coupler is a type of nut without threads. When connecting, the cold-extruded coupler is placed over the two ends of the steel bar connectors and then put into a special pressing device. According to the specified number of crimping passes and indentations, pressure is applied to deform the nut, thereby connecting the two steel bars.

Cold extrusion rebar couplers are simple to manufacture, highly efficient, and productive. During the extrusion process, there is no need to heat the metal billet. The billet is simply extruded into the desired shape by force, which saves energy and time costs.

Cold extrusion rebar couplers have high-precision surface quality. Since the extrusion is carried out at room temperature, problems such as metal thermal expansion and oxidation are avoided, making the shape and size of the product more accurate and the surface quality more excellent, meeting different strict requirements.

Cold extrusion rebar couplers require less material, which can reduce costs. Since extrusion can change the shape of the metal billet without altering its material properties, waste and material consumption are effectively reduced.

Cold extrusion rebar couplers have excellent mechanical properties and wear resistance. During the extrusion process, the metal molecular structure is highly compressed and flows, resulting in refined grains of the product, improving the strength, hardness, and wear resistance of the material and extending its service life.

Cold extrusion rebar couplers are suitable for a wide range of materials to meet the needs of different industries. Whether it is construction steel, aluminum profiles, copper materials, stainless steel and other various metal materials, nuts of various shapes and specifications can be manufactured through the extrusion process, which are widely used in machinery, automotive, aerospace engineering and other fields.

In general, cold extrusion rebar couplers have the characteristics of being simple and efficient, having high precision, requiring less material, having excellent mechanical properties, and being suitable for a wide range of materials. It is a metal manufacturing process worthy of promotion and application. It is hoped that the extrusion technology can be more widely used in the future to bring more economic benefits.
