The mold manufacturing technologies that our group (Dynamo / Nippon Seiki) has continuously pursued are a valuable asset — encompassing both the design expertise that enables and optimizes the casting of various products, and the machining technologies that have been refined to achieve the highest levels of quality and cost efficiency.
These technologies represent not only our heritage but also the driving force to pioneer a new future for the die-casting industry.

By integrating our established technologies with Additive Manufacturing (AM), we are now able to realize innovative mold designs once thought impossible.
Through AM technology, shapes and mechanisms that were previously unimaginable or unattainable with conventional machining can now be achieved.
The fusion of traditional and additive methods allows for an unprecedented level of freedom in mold design.

Beyond free-form cooling channels and lattice structures, AM also enables the integration of multiple components into a single, consolidated part — achieving improvements not only in cost and functionality, but also bringing true innovation that transcends conventional limits.
With this spirit of creativity, we aim to drive the die-casting industry forward into a new era.

[Our Group’s AM Business]
In August 2021, we launched our Additive Manufacturing (AM) business and introduced two GE M2 3D printers.
We achieved the industry’s first production of 3D-printed mold components using SKD61 powder material, which has since been implemented in mass production.

What differentiates us is our fully in-house production system — covering every process from design, printing, heat treatment, finishing, to quality assurance — and our success in solving issues commonly seen in 3D-printed components made with maraging steel. Our parts have also demonstrated proven performance at customer sites.

While palm-sized parts were once the mainstream, we have now produced over 800 units up to 240 mm square, and with the introduction of the LPM450 machine in October 2024, we are now capable of handling components up to 450 mm square.
