Machinery & Motor vehicle division


We assist our customers' prototype development
to small-lot mass production


From prototype development to small-lot mass production, we have worked on various projects as a development and prototyping factory for each manufacturer with an integrated production system.

We can also assist customers with small lot mass production parts, from the product concept stage to prototype development for launching mass production.

Wide items range from sheet metal parts to machined parts.

We work with customers globally, from domestic manufacturers to overseas manufacturers, and respond to a variety of customer requests.

C-COM's production system aims to shorten
development lead times and improve costs
by leveraging an integrated production system

By conducting repeated examinations in SE activities and various simulations, and making 3D prototypes, we are consistently examining structures, shapes, and process designs that are difficult to judge with 2D drawings.
