Die-casting machines
We possess die-casting machines rated between 135 tons and 3,550 tons (across the entire Group) and are thus capable of producing products of various sizes.
In addition, we are helping to ensure uniformity in terms of quality and a stable supply of products by installing industrial robots and post-processing systems on each machine.
Machines for processing products
We enable high-speed cutting for complex and special shapes and forms and can achieve a product finish with shapes and forms of even greater precision. We are able to mass produce products to meet a diverse range of needs as indicated by our clients.

| Evaluation facilities and equipment | |
| X-ray measuring machine | Inspection equipment that is used to irradiate an object with X-rays in order to detect such defects as cavities, voids, and foreign matter inside die-cast products. |
| X-ray fluorescence analyzer | Equipment that is used to irradiate a sample with X-rays in order to analyze the energy of the fluorescent X-rays that are thereby generated and to determine the type and amount of each constituent element in the sample.す |
| 3D scanner-type coordinate-measuring machine | A machine that uses a 3D scanner to measure and inspect the dimensions of molds (inserts). |
| Spectroscopic analyzer | Performs stable, highly accurate material evaluations of multiple elements found in metals by way of spectral analysis. |
| Oil concentration-measuring machine | Accurately evaluates the residual oil content in machining oil and abrasive agents used for die-cast products. |
Kumagaya Mold Center
Electrical discharge machines
Electrical discharge machines enable high-precision and high-efficiency processing. In addition, our accumulated processing technologies make it possible to manufacture complex molds through in-house operations.
Non-contact measuring machines
We check machined parts using non-contact measuring machines. By comparing filmed results with models as part of the checking process, we can verify the precision of not just structural parts but also free-form shapes.
