R & D support

Support R & D by utilizing many achievements and technologies

We have been manufacturing various industrial parts to support R & D.
Leveraging our many achievements and experiences, we will use the various technologies we have cultivated to provide R & D support from customer prototyping to actual machine verification processes and quality assurance tests.

METAL CASTING

Aluminum / cast iron / cast steel / various metal casting

We have been involved in casting production for various customers and have gained a lot of trust.
We produce high quality sand castings by fusing 3D CAD and artisan techniques.
01
Wood mold method
Design a wooden mold based on 3D data and manufacture the wooden mold by machining.
As a feature, it can respond to mass production and flexible shape changes.
02
AM method
AMBy adopting the AM method（Additive manufacturing）, sand molds can be made directly from 3D data without using wooden molds.
As a feature, it is possible to respond with high quality and short delivery time without a wooden mold.
03
Casting (Aluminum / cast iron / cast steel / various metal casting)
Pouring water (melted aluminum, etc.) is poured into the mold.
We respond to the needs of high-quality prototypes using the techniques of "advanced technology" and "takumi".
04
machining
Proto has introduced the latest equipment such as a vertical and horizontal machining center as well as a 5-axis control machining center in order to respond to all requests.
We select the most suitable processing machine according to drawing tolerances and processing direction to meet various demands.
05
3D measurement
We measure with the world's highest level CMM.
It measures every machined surface in micron units to determine if the product is completed according to the drawing tolerances.
For a curved surface shape that cannot be measured by 3D measurement, a non-contact 3D digitizer is used to compare and match with 3D data to confirm that there is no difference in shape.
