  • Optic-related and other jigs & tools, etc.



Message from Company Representative

Our technology, cultivated through the manufacturing of press dies/molds for electrical components in automobiles, enables us to cope with orders for precision processing of prototypes or small lot parts using various NC machines for a short delivery time. Our process is supported by the fusion of skill hands and computer controlled machines.

In particular, we have a unique material for prototypes of aluminum die-casting product. Most popular aluminum alloy for die-casting is called ADC12(JIS), AlSi12Cu2Fe(ISO), 383.0(ASTM), AC-46000(Germany) and so on. Our original aluminum is composed of the same materials as ADC12. Furthermore, our aluminum block is VOIDLESS (no cavity) and good for machining or cutting.

Cutting Surface of Our Voidless ADC12
Stock Size:230x380x1000mm

So, if you would like to make a prototype, we can machine from this special material. (We do not sell this material because we are manufacturer.) By this method, you can evaluate prototypes made by same constituent as mass die-casting production. Thus, we contribute to hasten your research and development period.


And then, we installed a metal 3D printing machine in December 2016.
The machine is Concept Laser M2. photo
We can print and post-process metalic materials.
Now, materials are 316L stainless steel and aluminum alloy.


We look forward to your continued support.

Representative Director and President
Hideki SEMBOKUYA, Dr. Eng.
