We would like to propose reducing the machining process from the material (round steel)!
At Tanaka Shintekko Co., Ltd., our forged products, "Backward Extrusion Forgings," allow for a reduction in the machining process from raw materials (round steel). The advantages include forgings with no taper on the inner and outer diameters, at a 0-degree angle. The shape is cup-shaped. Currently, the dimensions we have achieved are an outer diameter of φ80 to 120mm, a total length of 125 to 225mm, an inner diameter of φ61 to 85mm, and an inner depth of 70 to 190mm. The materials we currently use are S45C and SCM435. In the future, we will challenge ourselves to achieve maximum and minimum dimensions for outer diameter, inner diameter, total length, and inner depth beyond our current specifications. We will also take on challenges for shapes other than round for the outer and inner diameters, as well as for materials with unique characteristics. For more details, please contact us or refer to our catalog.

Company information
Tanaka Nobu Iron Works Co., Ltd. is engaged in the manufacturing of products as a die forging company located in Nogata City, Fukuoka Prefecture (Nogata Industrial Park). Since its establishment by my grandfather, Nobu Tanaka, we have upheld the principles of trust, responsibility, and sincerity as our corporate motto, and our employees work together as one. The economic situation in the industrial sector is extremely challenging, and we feel a strong sense of crisis and responsibility. Although we are a small company, we leverage our extensive experience to enhance our technical capabilities, with veteran craftsmen and mid-level and young employees working together to take on daily challenges in forging and processing. We specialize in die forging using screw presses, which is rare nationwide, and we uniquely combine it with free forging. Even with the limited number of die-forged products, we strive to meet our customers' needs and make proposals accordingly. Furthermore, moving forward, we aim to increase the added value of technologies and manufacturing methods that only Tanaka Nobu Iron Works can provide, with a focus on distinctive production methods and forged products.
