Precision Blanking of Hard, Thin Materials

Our origin is blanking camera aperture blades. Since our founding, we have refined the technology to blank hardened ribbon steel, a hard and thin material, with micron-level precision. Applying this technology, we also handle SUS (SUS301CSP / SUS304CSP) flat springs, full-perimeter shearing of aluminum, and combined hemming, curling and coining of terminals. We design and build our dies in-house and feed mass-production results back into die design.

* As a thin-sheet record, we have blanked SUS material at t0.01 mm (prototype level; please consult us about mass production).
