FINE COMPONENTS DIVISION-Precision Functional Parts


Following detailed consultations with our clients, we design and develop original products speedily and precisely, using our cutting-edge 3D printer.


We have all the technologies and services required for high volume hardware production, including automated assembly lines, where our original product 'ONIME' Insert Nut is produced. We also do zinc die-casting and manufacture the tools required for zinc die-casting in our own facilities.

Manufacturing Control / Technical Control

Each product is manufactured to the highest technical specifications. We ensure quality in the plant by producing our own tools for manufacture and assembly. Every staff member knows that PPM and quality control are critical to our success.


Every MURAKOSHI product is thoroughly tested according to Japan Industrial Standards (JIS). We are able to test several products simultaneously, 24-hours a day, using our unique robot, which simulates the full spectrum of human movement.
