Our free forging presses have many features as the world’s most advanced forging equipment, equipped with control systems and auxiliary equipment that make full use of state-of-the-art facilities. In addition, since the mid-1960s, we have been accumulating a great deal of manufacturing experience and know-how that has led us to the present day, with presses that emphasize not only high performance, but also stable long-term operation and long service life.
Large free forging presses
These presses are most suitable for manufacturing ultra-large products such as rotating shafts and thrust collars for power generation, connecting rods for diesel engines, and propeller shafts for ships. In addition, our presses are recognized as safe presses that can withstand severe conditions, such as large eccentric loads and sudden load fluctuations during the process for each product, as well as prolonged exposure to radiant heat emitted from red-hot materials.
Medium free forging presses
Like large presses, these are used to manufacture (downsized) rotating shafts for power generation and propeller shafts for ships, as well as high-temperature pressure vessel upper lids, bodies, and bottom lids. What differs from ultra-large products is that the temperature drops faster due to the smaller workpiece size. Therefore, where forming is required within a limited allowable temperature, the hydraulic control technology we have cultivated to date has enabled us to achieve high-speed, high-precision responsiveness and to reduce pressing time.
Small free forging presses
Pull-down type presses
Pull-down type presses are mainly operated under 5,000 ton in terms of pressing capacity. The pull-down design also enables installation in a low housing because the height from the floor can be kept low due to its structure. Furthermore, because the center of gravity can be lowered, the frame itself has less deflection under eccentric loads, making it ideal for forging that requires precision.
Hydraulic presses, etc.
Without limiting ourselves to free forging presses, we are also expanding into various types of presses by applying our hydraulic control technology. Typical examples include sizing presses for correction of products, multi-function presses for forming automotive engine valves, and coining presses for forming crankshafts. We can meet a variety of needs.
