オーエフ工業 List of Products and Services

The "cold roll forming" we perform involves a processing method that bends materials like stainless steel into various shapes, much like origami. Our company has produced roll molds with excellent precision and quality, thanks to the advanced technology accumulated over many years. We supply molds processed into sizes and shapes that meet current demands, and we currently have over 900 types of molds available for production. Additionally, we achieve high precision with deviations such as twisting, warping, and bending kept within 1mm per meter, enabling the formation of shapes that cannot be bent with presses or benders, as well as the shaping of long materials, allowing for sharp corners. We have various processing examples, including architectural components and pipes. *In our processing case collection, examples such as vehicle door rails and rail components are included! For more details, please refer to the PDF materials or feel free to contact us.*

Here are some examples of the "cold roll forming" processing we perform at our company. We can process shaped steel, such as "vehicle door rails" made from SS41 material with an unpolished surface treatment, and "rail components" made from SUS304 material with HL polishing. Additionally, we have various processing examples for building materials and pipes. 【Shaped Steel Processing Examples】 ■ Vehicle Door Rail ・Material: SS41 ・Surface Treatment: Unpolished ■ Electric Vehicle Door Rail ・Material: SUS304/SUS821L1 ・Surface Treatment: Unpolished ■ Rail Component ・Material: SUS304 ・Surface Treatment: HL Polishing *For more details, please refer to the PDF document or feel free to contact us.

Our company was founded in 1948 by Yoshiharu Yoshikawa, who successfully transformed the conventional drawing bench and die type into a roll type for the molding of bus components. In conjunction with this, we began the production of various types of steel and have been on a path of improving cold roll forming technology and research and development for the past 70 years. In the 1950s, we laid the foundation for roll-type drawing benches and quickly introduced computer-aided design technology. This enabled us to complete high-precision roll molds and respond to various user needs. In 1985, we changed our company name to "OF Kogyo Co., Ltd." and made a fresh start, leading us to the present day. Moving forward, we will continue to actively engage in the development of stainless steel products that meet the needs of the next generation with creative ideas across the entire company. *For more details, please refer to the PDF materials or feel free to contact us.*

This is an introduction to the production technology of OEF Kogyo Co., Ltd. There are two methods for cold roll forming: the roll extrusion method using a forming machine and the roll drawing method using a drawing bench. Depending on the lot size, shape, and plate thickness, we select the forming method that maximizes the characteristics of the formed products. Our advanced technology, accumulated over 70 years, enables us to create highly precise roll molds, with over 1,000 types of molds available for production. We have established a system that can adequately respond to the demand for a variety of products in small lots, and our technical staff's professional mindset has successfully cleared various technical challenges. 【Features】 ■ A system that can adequately respond to small lots ■ Selection of forming methods that maximize the characteristics of the formed products ■ Creation of highly precise roll molds, with over 1,000 types of molds available for production ■ Successful resolution of the long-standing issue of springback in the forming industry *For more details, please refer to the PDF materials or feel free to contact us.
