Technology
Our company was founded 45 years ago upon the manufacturing of progressive stamping dies, and technology expanded to automatic press production, multiforming fabrication, and transfer fabrication, and even today we continue challenging fine blanking fabrication which supports the bulk of today's business.
This stamping tool and die technology is the undercurrent of our company's technology. This technology is the key of modern mechanical fabrication and thus forms the pillar of high profile Japanese export markets such as cameras, automobiles, electric, and electronic products. Our company's die technology contributes to the fabrication of pressed parts for the automobile industry which is still representative of Japan today.
We are especially proud of fine blanking parts irreplaceable for the safety and reliability of automobiles, and we maintain our position in the top class of domestic manufacturing. Furthermore, we expanded with this technology to Kentucky, U.S.A., and even now our company's products are used by the Big Three auto makers GM, Chrysler, and Ford.
Fine-Blanking working image
| FB fabrication can finish a part all at once by punching the material to be fabricated with high precision. Therefore, the outer frame that is necessary for normal stamping becomes unnecessary; and secondary operations such as reaming holes, milling, etc., also are unnecessary. The method in which punching is performed by controlling the flow of the material of the shearing portion of the punched material is called fine blanking. Namely, a high compressive stress is caused to occur in the interior of the material, cracks are prevented by increasing the ductility of the material, and a beautiful sheared surface that is perpendicular and has no fracture is obtained by using a plate holder that has a knife edge-shaped V ring, a counter holder, and punches and dies that have extremely small clearances. |
