Machining Sector

In 1938, one year after the foundry sector, the machinery plant of Joban Machinery Co., Ltd started running.
The machinery plant has been operated broad production from the precision work for small parts to large parts for construction machines, and now the plant created the integrated manufacturing system including the assembly of hydraulic motors using our existing strength that we can make foundry materials on its own.
Our hydraulic motor is used worldwide under the brand name of KYB Co., Ltd and is highly trusted.
Of course, we specialize in processing of a part unit as used to be.
