Supports 5-part processing of tire molds. We focus on suppressing the drum phenomenon and managing the shape in the thickness direction, pursuing split surface accuracy with assembly in mind.
At Hanshin Seiko, we accept the division processing of tire molds using wire cut electrical discharge machining. The article features the processing of dividing a ring-shaped tire mold into five parts. What we emphasize is not only the accuracy of the division position but also finishing the cut surfaces straight in the thickness direction. We take into account the drum phenomenon, which causes bulges or depressions near the center of the processing surface, and comprehensively consider discharge conditions, processing fluid conditions, wire tension, and feed rate. For large ring-shaped molds, we explore support and holding methods that minimize deformation due to fixation. We also consider the effects of changing rigidity and residual stress as the division progresses, and we organize the setup with an eye on the processing sequence and holding after separation. If you have any concerns about gaps in the cut surfaces or adjustments during assembly, please feel free to consult us. Along with the drawings, please provide information on material, outer diameter, height, weight, number of divisions, cutting costs, required precision of the cut surfaces, and desired delivery date.

basic information
【Processing Details of the Case Study】 Processing Target: Annular Tire Mold Processing Method: Wire Cut Electrical Discharge Machining Number of Divisions: 5 Divisions Quality Focus: Division Position, Straightness and Flatness of Cut Surfaces, Condition of Machined Surfaces Considerations: Suppression of Drum Phenomenon, Discharge of Machining Chips, Stability of Wire, Deformation Due to Fixation, Processing Sequence, Retention After Separation *Corresponding dimensions, weight, tolerances, and surface roughness will be provided after confirming the drawings and installation/holding conditions. Please also inform us of the number of divisions, cutting allowances, and requirements during assembly.
Price information
This is an individual estimate for each drawing. We will confirm the material, outer diameter, height, weight, number of splits, cutting position, cutting cost, required precision of the split surfaces, and the details of finishing and inspection before providing the estimate.
Delivery Time
※We will check the dimensions, weight, number of splits, setup conditions, finishing processes, and equipment operating status of the mold, and provide you with individual guidance. Please let us know the scheduled delivery date and your desired delivery date.
Applications/Examples of results
【Processing Results】 The annular tire mold was divided into five parts using wire cut electrical discharge machining. This is an example of efforts to suppress the drum phenomenon and manage the shape in the thickness direction. 【Consultation Topics】 - I would like to request the division processing of a tire mold. - I want to suppress bulges and dents near the center of the split surface. - I want to minimize gaps at the joining surfaces of the mold. - I want to process with consideration for the assembly work during assembly. - I would like to consult about methods for holding and separating annular molds. *This is a contract processing service for molds. Since burrs during molding are also related to wear, assembly, and molding conditions, we do not guarantee the elimination of burrs through processing alone.*
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/
