Quick response and high quality! We will meet all market needs with a customer-oriented approach.
Kiryuu Meiji Co., Ltd. started as a sole proprietorship, Kawanakako Seisakusho, in 1967. Initially focusing on secondary processing, we enhanced our technology using lathes, bench lathes, milling machines, and more. In line with production volumes at the time, we introduced cam-type automatic lathes and handled various parts as the times changed. Later, in response to demands for high precision and quality, we focused on NC automatic lathe processing, working on shafts and precision parts. In recent years, we have also taken on the challenge of small-batch, diverse production of difficult-to-machine materials and high-precision components. Moving forward, we aim to improve our technology and stabilize quality while nurturing young talent and uniting as a team to be loved by more customers, advancing step by step with the motto of "Good products quickly and at low cost." 【Business Activities】 ○ Various precision parts (Semiconductors, medical devices, electronic components, construction machinery, gaming machines, OA equipment shafts) ○ Processing, manufacturing, and assembly of various automotive parts For more details, please contact us or download our catalog.
