The Ronen® Heavy Duty Thread Rolling Machine is specifically designed for manufacturers who produce thick metal components. All you need to do is attach the thick rod and install the wheels, and it will work smoothly. You don't need to check it frequently. Once the roller is set up, it can run continuously for several hours.
The Heavy Duty Thread Rolling Machine is specifically designed for rolling threads on thick shaft materials. It can be used to roll the shafts of large bolts, transmission shafts, and other similar components. During operation, the machine uses two large rollers to press the shaft material.
The Heavy Duty Thread Rolling Machine is used to form threads on large-diameter or high-strength components. It applies extremely high pressure, causing the metal on the blank to shift and forming an external thread through cold forming. This machine is specifically designed for large bolts, anchor rods, or construction steel bars, and standard thread rolling machines cannot provide sufficient force and rigidity.
The tonnage of the Machine is much higher than that of the standard model. It features a sturdy rolling head and is usually equipped with two to three large-diameter cylindrical dies to apply the necessary force. The frame, shaft, and bearings have all been reinforced to be able to withstand the high stress generated when processing hard materials or large-section workpieces, and will not deflect.
The tooling for the Heavy Duty Thread Rolling Machine is composed of large hardened steel molds. These molds feature a specific thread shape design and are capable of withstanding extreme pressure. Due to size and cost considerations, mold replacement is more complex, and the mold lifespan is a key factor in the operational cost of this process.

The selling point of the Heavy Duty Thread Rolling Machine is that it can roll thicker materials and has a strong force. The thread depth is sufficient and the tooth profile is complete. It can easily roll a 40-millimeter diameter hard steel rod, and the rolled threads have high strength. They are not prone to breakage when used in large equipment.
