The Ronen® Flange Nut Forming Machine, a reliable solution for manufacturers, shapes the metal blank into a flange nut. It presses the blank material at one time to form the internal threads of the flange and the nut. For manufacturers, all you need to do is load the raw material, set the dimensions, and it will complete the shaping process—greatly streamlining production workflows.
The Flange Nut Forming Machine is specifically designed to process metal wire into flange nuts. The machine can simultaneously extrude both the edge of the ring and the hexagonal head of the nut at one time. The available specifications for flange nuts range from M4 to M20.
The Flange Nut Forming Machine is a cold extrusion machine specifically designed for manufacturing flange nuts. It uses steel wire, cuts it into blanks, and then uses a series of molds and punches to perform cold forming on the nuts. This process forms an integrated flange-like gasket at the bottom of the nut, and automatically punches out the center hole without the need to heat the material.
The Flange Nut Forming Machine starts with a coil. The unwinding machine feeds the wire into the straightening mechanism to eliminate any bends. Then, the precision cutting machine cuts the straightened wire into blanks of a specific length. The volume of the blank is crucial because it must contain enough metal to form the hexagonal body of the nut and the wider flange part.
A key stage in the operation of the machine is the forming of the flange. The punch presses the blank into a mold cavity that is wider than the hexagonal section. This causes the metal to move radially outward, forming a flat circular bearing surface at the bottom of the nut. The diameter and thickness of the flange are controlled by the mold design.

The feature of the Flange Nut Forming Machine is its ingenious mold design. The mold has specially designed grooves corresponding to the flange edge, which enables precise control of the thickness and diameter of the flange edge during the extrusion process. The extrusion force of the machine can be adjusted, the feeding is stable, and the error in the cutting length of the wire is small.
