群協製作所 Company Profile

Leave screw, fittings, and laser nozzle processing to Gunkyō Seisakusho!

Since its establishment, Gunkyō Seisakusho Co., Ltd. has developed with the support of many users as a manufacturer of copper fittings and valves for instrumentation and air conditioning. Currently, we have leveraged that technology to enable the processing of various precision parts. We specialize particularly in small-diameter precision lathe products, small-batch and single-item prototypes, various screw processing (PT, PF, NPT, Unified, inch screws, etc.), and non-ferrous metals (including plastics). Additionally, we also engage in can manufacturing, sheet metal work, welding processing, and assembly, assisting in the production of products that include metal through complex processing. We can handle processing that other companies tend to avoid, so please feel free to contact us.
