群協製作所 Company Overview

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

Gunkyō Manufacturing Co., Ltd. has developed with the support of many users as a manufacturer of copper pipe fittings and valves for instrumentation and air conditioning since its establishment. 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 machining (PT, PF, NPT, Unified, inch screws, etc.), and non-ferrous metals (including plastics), among others. We also carry out 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.
