オーエフ工業 List of Products and Services

The "cold roll forming" that we conduct involves a processing method that bends materials like stainless steel into various shapes, similar to 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, our precision is high, with deviations such as twisting, warping, and bending kept within 1mm per meter, allowing for the formation of shapes that cannot be bent with presses or benders, as well as long items, enabling sharp cornering. We have various processing examples, including architectural components and pipes. *The processing case collection includes examples such as vehicle door rails and rail components! For more details, please refer to the PDF materials or feel free to contact us.*

We would like to introduce examples of processing using "cold roll forming" that we conduct at our company. We can process structural steel, such as "vehicle door rails" made of SS41 with an unpolished surface treatment, and "rail components" made of SUS304 with HL polishing. Additionally, we have various processing examples for building materials and pipes. 【Structural 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 Polished *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 modified the traditional 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 for the past 70 years, we have been dedicated to improving the technology of cold roll forming and pursuing research and development. In the 1950s, we established the foundation for roll-type drawing benches and quickly introduced computer-aided design technology. This enabled us to create highly precise roll molds, allowing us to meet various user needs. In 1985, we changed our company name to "OF Kogyo Co., Ltd." and embarked on a new start, which continues to this day. Moving forward, we will actively engage in the development of stainless steel products that can respond to the next generation with creative ideas, involving the entire company in this effort. *For more details, please refer to the PDF materials or feel free to contact us.*

This is an introduction to "Production Technology" by 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 wide variety of small lots, and the professional mindset of our technical staff has 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.
