Processing of irregular holes, small R, and cut shapes using wire cutting. Please feel free to consult us for single-piece production of replacement die plates.
At Hanshin Seiko Co., Ltd., we offer precision machining of die plates for press molds. Focusing on wire cut electrical discharge machining, we accommodate processing of irregular holes, inner corners including small radii, narrow slits, and complex cut shapes. We confirm specifications such as clearance with punches, pitch of multiple holes, and positional relationships with reference and locating holes through drawings, and consider processing methods. We also welcome inquiries regarding taper and relief machining in the plate thickness direction, as well as additional machining on die plates after hardening. We can handle wire diameters as small as φ0.15mm. Depending on the shape and finishing conditions, we will consider integrated processing that combines machining, shape cutting electrical discharge machining, and surface grinding. Please feel free to consult us about single-piece production of replacement die plates or remanufacturing based on drawings.

Company information
Hansei Seiko Co., Ltd. is a precision metal processing company founded in 1948, based in Kobe City, Hyogo Prefecture. We offer integrated processing services centered around wire cut electrical discharge machining, shape electrical discharge machining, and fine hole electrical discharge machining, as well as machining, polishing, finishing, and measurement. We welcome inquiries for precision parts, mold components, jigs, test pieces, and more, whether for single items, prototypes, or small lots. In addition to processing hardened steel, carbide, and stainless steel, we also handle contour machining of thick parts, key grooves, fine slits, and complex shapes. We confirm material, shape, required precision, and application, and consider processing conditions and processes. This reduces the burden of arranging multiple processing locations and supports part manufacturing. Based on the principle of "making according to the drawings," we conduct inspections and measurements in-house to confirm the finish before shipping. Based in Kobe and Hyogo, we accept processing inquiries and quotation requests from across the country. If you have parts you are struggling to process or drawings for which you would like to consider methods and processes, please feel free to consult with us. https://www.hansei.co.jp/
