Please consult us about the small diameter hole of the orifice nozzle. We will check the hole diameter and depth, tolerances, and the condition of the inlet and outlet, and consider the processing method using fine hole discharge.
At Hanshin Seiko, we accept inquiries regarding the machining of fine holes and small diameter holes necessary for orifice, nozzle, and flow path components. We have equipment capable of fine hole electrical discharge machining starting from φ0.3mm, and we consider machining small diameter holes that are difficult to process with drills, as well as holes in high-hardness materials such as hardened steel. The feasibility of machining is determined by checking not only the hole diameter but also the combination of material, plate thickness, hole depth, and required precision. In orifices, the hole diameter tolerance, effective length of the hole, and the shape and condition of the inlet and outlet are important. We also confirm the necessary roundness and surface roughness, and consider machining and inspection methods according to the required specifications. We also consider responding to prototypes with different hole diameters, machining multiple holes, and adding holes to supplied parts. If machining of outer shapes, seating surfaces, or reference surfaces is required, please consult us about processes that combine machining, wire cutting, and polishing. Along with the drawings, please provide information on material, hole diameter and tolerance, hole depth, number of holes, quantity, intended use, and desired delivery date.

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/
