This section introduces the production equipment of the JUKI Ohtawara plant. The equipment mainly functions to process parts and apply heat treatments. The machines variously process small-lot parts, parts for prototypes, spare parts, and emergency response parts for industrial sewing machines. The parts for industrial sewing machines must be produced with micron-level precision. We therefore apply precision technologies to the parts being processed at the request of customers in the manufacturing industry (based on a contracted development and manufacturing business). JUKI has advanced know-how in heat treatment processes such as carburizing quenching and temper, ion nitriding, and neutral salt-bath furnace immersion.
