Automotive division


We assist custmors' development and prototyping.


We engaged in various activities as a development and prototype factory for manufacturers.

We will assist with the development of prototypes for mass production launch, from the product concept stage.

We can provide consistent support from single parts such as Body Side Outer, Back Door, and Hood to BIW (Body in White).

We respond globally to customers from domestic manufacturers to overseas manufacturers, and respond to customer requests as a development and prototype factory.

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