For tooth shapes, shaft holes, and keyways that do not fit standard products, please consult us for individual or prototype processing of special sprockets.
At Hanshin Seiko Co., Ltd., we accept consultations for the processing of special sprockets used in conveying devices, dedicated machines, and automatic machines. We will confirm the shapes and positional relationships of tooth profiles, shaft holes, key grooves, and mounting holes, and consider integrated processing that combines wire cut electrical discharge machining and machining. We will reflect the specified angular positions in the drawings during the processing steps, such as aligning the center of the teeth with the center of the key groove. You can consult us about parts that do not fit standard dimensions, thin sprockets, single items for prototype devices, and replacement parts for existing equipment. We will guide you on processing methods tailored to material, plate thickness, quantity, and required precision, whether it involves additional processing of commercial products or manufacturing from raw materials. Please contact us with chain specifications, detailed tooth profile drawings, CAD data, required 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/
