From holes, grooves, and contours of small parts to the finishing of reference surfaces. Integrated processing combining wire cutting, discharge machining, and polishing.
At Hanshin Seiko Co., Ltd., we accept the processing of small precision machine parts, mold parts, and jigs. We offer integrated processing tailored to shapes and required precision by combining wire cut electrical discharge machining, shape electrical discharge machining, fine hole electrical discharge machining, machining, and polishing. We consider processing methods for each area, including through holes, irregular holes, outer contour, bottom shapes, fine grooves, small diameter holes, and finishing of plate thickness and reference surfaces. We also examine the positional relationships between holes and outer shapes, grooves, and reference surfaces, and consider methods for transferring processing standards across multiple processes. We plan the processing sequence with consideration for the holding of small parts and the shapes during processing. Please consult us for single items, prototypes, small lot production, and additional processing on supplied items. Please contact us with the overall drawings of the parts, along with material, tolerances, quantities, and desired delivery dates.

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/
