Possible to Develop at Low Cost and in A Short Period of Time

Since the environment for development has already settled, there is no need for new capital investment, leading to reductions in development costs and production lead-time.
We have various press machines for prototyping forged products without stopping customer's production line.

Enclosed Die Set


Extensive Environment that can Respond Flexibly for Various Test Purpose

Yamanaka Eng could provide various measuring equipment for suporting customers not only on trial production but also analysis and evaluation of pre-made tools that owned by customer.
In addition, with a dedicated building for prototypes and development, YEG have a complete system in place for confidentiality management.
