We manufacture molding dies for plastic and MIM (Metal injection molding) products. Our MIM can manufacture products that have high precision and low shrinkage (density: 95% or more) using original compound. We have group companies in Tokyo,	 China, and Vietnam. 


  • New material metal powder injection molding (MIM)

    New material metal powder injection molding (MIM)

    [Product description] Comparison with conventional MIM products: 1) Our new MIM has a higher density of 98%; 2) It achieves functionality enhancement (higher hardness , 20% increase in wear resistance); 3) It reduces shrinkage rate by 5%; 4) It can expect a lower error of dimensional accuracy (0.5% or lower) . The expected effects: Secondary cutting processing is unnecessary due to parts accuracy improved; Secondary treatment can be reduced due to higher performance.

[Company strength]
We have group companies in Tokyo, China, and Vietnam. The Tokyo office is responsible for operation, planning, and sales;	 China for die design,	 and Vietnam for die manufacturing and MIM mass production. We establish our own network system shared by the group companies. We can, therefore, offer an integrated production by sharing the same data and can provide highly productive, highly accurate, and low-cost products. 

[Business description]
We offer an integrated production of molds (die design,	 manufacturing, and molding) for MIM and plastic products. We develop new materials for MIM products and manufacture jigs and tools. We also provide high-accuracy and low-cost products in cooperation with group companies in China (Ningbo) and Vietnam (Hanoi). 

3D design and manufacturing of injection molding dies for MIM and plastic products; MIM mass production 

[Strength of products/technologies]
We have skilled engineers who have the exact processing expertise. We can produce a high-precision and low-shrinkage mold, which is produced by original compound, keeping a density of 95% or more for a MIM product. In addition	, we have a high employee retention rate, offer an integrated production	 from design to production, and can, therefore, ensure a thorough compliance with any confidentiality agreements. 

[Representative's message]
We established our mass production plant in Vietnam as one of our group companies in order to achieve globalization from Tsugaru, Aomori	. We process and accumulate our database in Japan and share the same equipment and technologies with our companies overseas via the Internet, in response to the needs of major companies. 

[Company structure for market development/overseas expansion]
We have offices in Tokyo downtown, Tokyo (Hachioji)	, China (Ningbo City, Zhejiang)	, and Vietnam (Hanoi).	 We also have group companies overseas and are already promoting the overseas expansion. Our sales office in Hachioji is capable of responding to the requests from major companies in a prompt and reliable manner.
