From material to completion, we provide integrated processing in-house. By combining cutting, polishing, wire cutting, and shape electric discharge machining, we manufacture complex rubber extrusion mold components.
At Hanshin Seiko, we offer comprehensive manufacturing of mold components that combines cutting, polishing, wire-cut electrical discharge machining, shape electrical discharge machining, and finishing. The case presented is an "overlapping base" used in rubber extruders such as those for tires. With a total length of 400mm and varying shapes at an angle of 26.6°, we carried out all processes in-house from material to completion, adhering to a dimensional tolerance of ±0.025mm. Considering distortion caused by processing, we designed the process with foresight from the cutting and polishing stages to the subsequent electrical discharge machining. We examined the upper and lower contours and the processing surfaces connecting them, utilizing wire-cut and shape electrical discharge machining as appropriate for the shapes. We welcome inquiries such as "I would like to request parts that require multiple processes together" or "I want to process different shapes on the upper and lower parts to specified tolerances." Please provide us with the drawings along with material, dimensions, required tolerances, quantities, and desired delivery dates.

basic information
【Processing Conditions for Published Case】 Part Name: Overlapping Base Application: Mold component that forms the flow path inside a rubber extrusion head Total Length: 400mm Processing Shape: Upper and lower shapes with an angle of 26.6° Required Dimensional Tolerance: ±0.025mm Processing Steps: Cutting → Polishing → Wire Cutting → Die-sinking Electrical Discharge Machining → Finishing Manufacturing System: All processes from material to completion are carried out in-house Rust Prevention Measures: Rust prevention treatment on non-machined surfaces *The values are the conditions for this case. They do not guarantee the same precision for all materials and shapes. The feasibility of processing will be confirmed by reviewing the drawings.
Price information
This is an individual estimate for each drawing. We will confirm the material, dimensions, processing shape, required tolerances, quantity, and the production and finishing details of electrodes and jigs. Please also let us know whether it includes material procurement or if the material will be supplied.
Delivery Time
※We will confirm the arrangement of materials, supply conditions, processing steps, preparation of electrodes and jigs, quantities, and equipment operating status, and provide individual guidance. Please consult us with your desired delivery date.
Applications/Examples of results
【Processing Achievements】 Consistent production of an over-wrapping base used in rubber extruders for tires and other applications. This is an example of in-house processing from cutting to discharge machining and finishing, under the conditions of a total length of 400mm, with upper and lower non-uniform shapes at 26.6°, and a dimensional tolerance requirement of ±0.025mm. 【Processing Services Available for Consultation】 - Production of rubber extrusion mold components - Machining of complex shapes with different contours on the upper and lower sides - Production of components combining cutting, polishing, and discharge machining - Mold components requiring consideration for distortion due to processing - Integrated processing for multiple processes requested together *This is a contract manufacturing service based on drawings, not the sale of standard molds.
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/
