Prototype production

We can meet customers’ diversified needs flexibly even from a prototype manufacturing processes.

Prototype manufacturing is not only an expression of the process of customer needs, but is also the most important process that decides the full production method. Nakamura, with its abundance of prototype machines and its experience as a specialist gear manufacturer, can produce prototypes to meet the demands of the customer. Furthermore, we can propose plans on VA (Value Analysis) and VE (Value Engineering) as a trusted partner to improve precision and the material used in the production of gears to improve future production.
