The Screws Making Cold Header Machine manufactured by Ronen® can shape the screw heads without heating the metal. It uses pressure to shape the metal wire billet into a screw head. You just need to insert the wire, and the machine will shape the screw head within a few seconds.
The Screws Making Cold Header Machine is specifically designed to produce screw heads by cold heading method. It does not use heated wire materials. Instead, it directly feeds the metal wire into the machine and through the mold, presses one end of the wire into the shape of a screw head.
The Screws Making Cold Header Machine forms the screw heads through a cold forging process at room temperature. This equipment receives the wire, straightens it, and then cuts it into precise blanks. Then, these blanks are transferred to a series of molds, where powerful punches impact one end of them, causing the metal to be extruded and shaped into the form of a screw head without removing any material.
The Screws Making Cold Header Machine starts with wire rods. The unwinding machine feeds the wire into the straightening mechanism to eliminate any bends. Then, the precision cutting machine cuts the straightened wire into billets of specific lengths. The consistency of these billets is crucial as it determines the amount of metal required for the correct formation of the head.
The Machine relies on hardened tool steel molds and punches. The molds contain cavities that determine the final shape of the screw heads. The punches apply force to shape the metal into that form. By changing these molds, the same machine can produce different types and sizes of screw heads.

The selling points of the Screws Making Cold Header Machine are very practical. It doesn't require heating, thus saving energy costs. The screw heads produced have high strength because during cold heading, the internal structure of the metal is compressed, making them more solid and less prone to breaking compared to those forged after heating. The material utilization rate is also high. In extrusion molding, there is no need to cut off the excess material, and the wire material can be basically utilized.
