No need for a drawing die because it's made with press bending and welding! Perfect for prototypes; single items are also okay! We can flexibly accommodate changes in dimensions and plate thickness with custom orders!
By using metal sheet press bending and welding instead of expensive molds, we can accommodate both prototype and mass production with short lead times. Despite being a welded structure, the fit with the lid is also good, and since we conduct helium leak tests on all units, the airtightness is guaranteed. We also manage special process certification and traceability according to your requirements. The weldable plate thickness ranges from approximately 0.1 to 2.0 mm, but we mainly handle welded products in the range of 0.2 to 0.8 mm. Additionally, for the welding of safety valves, it is possible even with thicknesses below 0.1 mm.

basic information
We manufacture various shapes of metal cases by bending thin sheets (0.1 to 2.0 mm) of stainless steel, aluminum, etc., using a press machine, and welding them with laser welding machines, TIG welding machines, and resistance spot welding machines. We can accommodate sizes as much as possible according to your requests, so please feel free to contact us first.

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.
