Hardness measurements after quenching are also conducted in-house! We will shape your requests based on drawings and samples.
We would like to introduce examples of processing for "automotive-related parts." In our core industry, we continue to shape our customers' requests from prototypes to mass production based on drawings and samples. We also conduct hardness measurements after heat treatment, such as high-frequency and nitriding processes, in-house. Our main materials are iron-based, but we also handle a significant number of processed products in brass and aluminum. We excel in mass-produced iron press products and secondary processing of small-lot, diverse cast products in aluminum and brass. Please feel free to consult us when you need assistance. 【Four Strengths】 ■ Technical capabilities that do not depend on specific industries or sectors ■ Improvement capabilities that eliminate waste, inconsistency, and overburden through centralized data management ■ Development capabilities that promote the enhancement of manufacturing staff's technical skills and multi-skilled workers ■ Networking capabilities that continue to build cooperation and collaboration with other companies in the same industry *For more details, please refer to the PDF document or feel free to contact us.

Company information
Otsuka Iron Works Co., Ltd. has been engaged in business with "cutting," "bending," and "welding" as our strengths since our founding. Currently, we provide and propose parts primarily focused on cutting processing, along with bending and welding. Recently, we have often taken on cases where we handle a complete set of machined parts, ensuring fit verification between parts and confirming compatibility before assembly at Otsuka Iron Works. Moving forward, we will continue to strive for further technological improvement and inheritance based on these three technologies to contribute to ongoing manufacturing. We will continue to build a system that provides "the necessary capital investment and technology for the times."
