The Ronen® High Speed Bolt Former is favored by many manufacturers. It can quickly transform metal wire into bolt blanks. It completes the shaping of the bolt head and the finishing of the shaft rod in one go. You just need to load the wire, set the size, and the machine will operate stably without frequent stops.
The High Speed Bolt Former is specifically designed for the rapid processing of bolt blanks. First, straighten and cut the metal wire. Then, using multiple sets of molds, continuously extrude the head and the shaft of the bolt. The entire process is fully automated.
The High Speed Bolt Former is a cold heading machine specifically designed to achieve maximum production output. Its basic functions are the same as those of a standard heading machine - cutting wire and forming bolt heads - but it has been optimized for cycle speed. The main design goal is to produce a large number of head bolt blanks per minute, making it suitable for mass production.
The machine features a heavier and more robust frame and a more sturdy crankshaft to withstand the higher stress caused by rapid operation. The drive system was designed with a well-balanced design in mind, resulting in minimal vibration at high speeds. Its robust structure allows the machine to operate reliably and reliably at its maximum specified cycle speed without the risk of excessive wear or malfunction.
One of the key features of the High Speed Bolt Former is its fast and precise transmission mechanism. The design of the fingers or clamps used to move the bolt blanks between various head stations is aimed at achieving minimal movement and quick startup. The timing of the transmission is crucial for achieving high-speed operation, as any delay between stations will limit the overall productivity.

The key features of the High Speed Bolt Former are its fast mold switching and high stability. The body is made of thick cast iron. During high-speed operation, it causes little vibration and won't cause the bolt head to be distorted due to shaking. Ensure that the weight and size of each piece of material are uniform, so that no further adjustments are needed during the subsequent processing of the threads.
