Tool Development (TTT Solution)


Starting with product analysis and incorporation of customer’s requests, we begin our tool design process.
During the process, we will consider changes in machine specification, installation or development of new optional features.

The making of tools will either be in-house or outsourced.  Initial tools made will be polished, assembled and adjusted in-house by experienced engineers at Nakashimada.
For example, press-fitting and machining for micro-parts tools is extremely difficult, we rely on our experience with hand-finishing.  An impeccable tool depends on how and how well the polishing was performed with diamond powder.
- carbide material selection
- tool construction
- analysis


Tools are set up on the selected machine type. Our experienced engineers will work swiftly towards setting up the machine according to customer’s requests.
