From design to manufacturing! A comprehensive solution for battery exterior components by Okita Manufacturing.
We provide one-stop solutions for concerns related to battery components, such as cases and lid assemblies! We will assist you from the design stage. Recommended for reducing initial costs as well.
At Daibei Manufacturing, we propose a comprehensive solution for battery exterior components, delivering welded structural battery cases and lid assemblies as a set. 【Product Features】 ■ Capable of handling prototypes and small-lot mass production! We do not use expensive stamping molds for the cases, which helps reduce initial costs, making it suitable for prototype to small-lot mass production (around a few thousand units per year). ■ Able to accommodate detailed requests! We provide a one-stop service from design to material procurement and manufacturing, allowing us to smoothly respond to small changes. ■ Good fit and airtightness The fit between the case and lid is carefully checked during production, ensuring no issues. Additionally, we conduct helium leak tests on all units of the case and lid assemblies to guarantee airtightness. If you have any concerns regarding battery components from the development to mass production of lithium-ion secondary batteries, please feel free to consult us. 【Manufacturing Achievements】 Cases (aluminum, stainless steel, titanium), sealing plates, current collectors, terminals, safety valve processing, rivet fastening 【Examples of Applications】 Prototyping to mass production of battery components for special applications such as aerospace Prototyping and development of battery cells for HV/EV applications.

Company information
Our company specializes in welding thin plates and manufactures precision welded metal cases and lids. We have in-house processes for laser, TIG, and spot welding, press forming, riveting, machining, water jet cutting, insulation coating, rolling, and He leak testing, allowing us to produce various metal processed products, starting with battery components. We also handle numerous products in the EV and aerospace fields, which require high quality, and we manage traceability as needed. In September 2015, we obtained JIS Q 9100 (ISO 9001) certification (Shimamoto Factory / manufacturing of special battery components for civil aircraft and aerospace). Additionally, we consistently perform the entire process of dissolving and rolling silver chloride plates in-house until they are processed into sheet form.
