By elongating the end of the material shaped by forging, it is possible to extend the forming limits of forging.
In the molding of long and hollow shafts, it is possible to utilize existing forging equipment. Sequential molding using spinning machines raises the limits of forging. Mass production of shafts that could not be molded due to stroke limitations becomes possible. Because it is sequential molding, entry into new products can be achieved with low equipment investment.

Company information
Nippon Spindle Manufacturing Co., Ltd. is a leading manufacturer of flow forming and metal spinning machines. Our technologies enable the production of axisymmetric components through incremental forming processes, offering an alternative to conventional forging and stamping methods. Because forming is performed gradually with relatively low forming forces, large presses and extensive production lines are often unnecessary. Flow forming technology can help manufacturers reduce capital investment while achieving lightweight and thin-wall designs with improved material utilization. It is particularly suitable for localized manufacturing, flexible production systems, and small to medium production volumes. If you are facing challenges such as high machining costs, excessive material waste, or demanding weight reduction targets, our flow forming solutions may provide an effective alternative. We support customers not only with machine supply, but also with process evaluation and feasibility studies based on part drawings and production requirements. Contact us to explore how flow forming technology can improve your manufacturing process and reduce production costs.
