The Ronen® Square Nut Forming Machine helps manufacturers shape metal blanks into square nuts. It first forms the raw material into a square, then adds internal threads—all in one go. Just load raw material into the feeder and set the size.
The Square Nut Forming Machine is specifically designed to press metal wire into square nut blanks. It doesn't require heating. Instead, it is directly formed by squeezing through a mold, and the process is very consistent. Carbon steel, stainless steel and copper wire can all be processed.
The Square Nut Forming Machine is a cold forging press used for manufacturing square nuts. It uses steel wire, straightens it, cuts it into precise blanks, and then uses high pressure to cold form these blanks into squares. This process involves upsetting the metal and punching a central hole without heating the material, thereby forming a nut blank suitable for thread processing.
The Square Nut Forming Machine starts with wire or sheet material. The unwinding machine feeds the wire into the straightening device to eliminate any bends. Then, the precision shearing machine cuts the wire into blanks of a specific length. The consistency of these blank lengths is crucial because it determines the amount of metal used to shape the square nut body into the correct size.
The machine relies on hardened tool steel molds and punches. The molds have square cavities to define the external dimensions of the nuts. These molds typically experience significant wear, especially at sharp corners. To maintain the quality of square contours and effectively avoid product defects, regular mold inspections, systematic maintenance, and precise grinding are crucial.

The selling point of the Square Nut Forming Machine is that it is specifically designed for manufacturing square nuts, with perfectly formed shapes and significant material savings. Its mold was precisely made according to the dimensions of square nuts. The pressed nuts have smooth surfaces on all sides and the corners are also square. It is cold extrusion forming. There is no need to cut off the excess material. The utilization rate of the wire can reach over 90%, which means much less material is wasted compared to cutting processing.
