The Ronen® High-Quality Bolt Making Machine,a valuable asset for suppliers, can transform metal rods into bolts with evenly distributed threads.It can complete the entire process from head shaping to thread cutting, without any additional steps. The bolts it produces are of uniform shape and meet industrial requirements.
The High Quality Bolt Making Machine is specifically designed to produce bolts that meet both high precision and strength standards. First, straighten the metal wire and cut it into a fixed length. Then, use a cold heading die to press out the bolt head, and finally, shape the threads.
The High Quality Bolt Making Machine is an integrated system used for manufacturing finished bolts. It usually combines the processes of cold heading and thread rolling. This machine uses steel wire, cuts it to the required length, forms the bolt head through cold heading, and then rolls the precise threads onto the bolt shaft. Ensuring the dimensional consistency of each bolt from the head to the threads.
The cold heading part of the High Quality Bolt Making Machine uses multiple stations to shape the bolt head. Progressive dies and molds gradually expand the wire blank into the final head shape. The machine maintains a high tonnage and precise alignment to ensure the correct head formation, with sharp corners, appropriate dimensions, and no surface defects.
The Machine employs a precision straightening machine to eliminate any bends in the wire before sending it to the cutting machine. The cutting machine then cuts the wire into precisely measured billets. Consistent billet volume is crucial for forming a complete bolt head, without any defects such as folding or under-filling.

The selling point of the High Quality Bolt Making Machine is that the quality of the bolts it produces is stable. Because the mold has high precision and the process connections are accurate, the size error of the bolts produced is very small. The bolt is of sufficient strength, and it can withstand greater pulling force than ordinary processed bolts. It is also less prone to breaking.
