Introduction of the preservative polylysine / fermented polyamino acids that contribute to food poisoning prevention.
We provide easy-to-understand materials explaining the natural preservative polylysine, which prevents food poisoning. ε-Polylysine (hereafter referred to as polylysine) is an amino acid-derived preservative widely used as a food preservative. By adding polylysine, the growth of microorganisms that cause food poisoning can be prevented. Every year, food poisoning caused by microorganisms is a significant issue and is frequently reported in the news. Even foods that do not appear to be spoiled can rapidly proliferate microorganisms if the growth environment is suitable, so caution is necessary. Even if something looks clean, contamination by bacteria can progress, posing a risk of food poisoning. By ensuring hygiene management during the manufacturing process, proper storage at appropriate temperatures, and the appropriate use of the preservative polylysine, food safety can be more effectively protected. 【Features】 ■ A safe material produced through fermentation by natural microorganisms (not genetically modified organisms) ■ Provides a good image as a natural fermented product ■ Listed in the existing additive registry as a food preservative ■ A safe domestic product *Please feel free to contact us.

What are the causes of dimensional issues in wire cutting? An explanation of the differences in thickness, die shape, and key points to check.
Hanshin Seiko Co., Ltd. has published a technical article titled "Causes of Dimension Issues in Wire Cutting | Checkpoints When Precision is Unstable." Issues such as "not achieving the desired dimensions," "dimensions differing between the top and bottom," and "only the intermediate section not matching the shape" highlight the importance of distinguishing whether there is a consistent dimensional deviation overall or if the shape of the machined surface is changing in the thickness direction. The article introduces factors to check, including correction amounts, wire deflection and vibration, machining fluids, material deformation, and temperature. It also explains our response examples, where we checked the top, middle, and bottom of thick materials and adjusted the machining feed rate and wire tension based on the measurement results. Please consider the approach of understanding the nature of the deviations and reviewing machining conditions rather than judging solely by correction values or the number of finishing passes. For inquiries regarding machining of thick materials with strict tolerances, please contact us with the drawings, material, thickness, and required precision. If you have already machined parts, please also provide the actual measurements and remaining machining allowances.

Consultation on processing SUS304 | Confirmation items that change with thin plate test pieces and thick key grooves
We would like to introduce the technical information of Hanshin Seiko. When requesting wire cutting of SUS304, it is important to convey not only the material name but also the plate thickness, final shape, and the state before processing. The original article discusses tensile test specimens of SUS304H-SR with a thickness of 0.1mm and the keyway machining of a large SUS304 gear with a thickness of 300mm. For thin plates, the points of confirmation are the condition after holding and removal, while for thick materials, the alignment with respect to the thickness direction shape and tooth profile is the focus. The dimensions of these two examples are not presented as a uniform processing range. When consulting, please inform us of the detailed material code, plate thickness, contour and tolerances, and which existing tooth profile, hole, or finished surface to use as a reference in the drawings. You can also check the guidance for each case from the related links.

Wire cutting or shape engraving | Check from the through-hole, bottom contact, and the way the electrode enters.
We will introduce technical information for selecting construction methods. Wire cutting is mainly considered for through contours, while shape machining discharge is examined for blind holes and bottom shapes. However, it is not solely determined by the names of materials and shapes. The wire path, the direction in which tools and electrodes can approach, inner corner radii, tolerances, and quantities must also be checked. For shape machining discharge, it is necessary to prepare electrodes that correspond to the shapes. When comparing not only the time required for processing the product but also the preparation processes, it becomes easier to consult. The original article from Hanshin Seiko provides guidance on the overall diagrams and cross-sectional views needed for method comparison, as well as how to organize material and treatment conditions, current processes, and points of concern.
Specifications for non-standard side dimensions and position/orientation can also be discussed. Hexagonal through holes are available from single items or small lots.

Wire cutting and shape engraving discharge machining in Tatsuno City | Modification and additional work of mold parts | On-site collection and delivery
Hanshin Seiko Co., Ltd. has published information on wire cutting and electrical discharge machining for businesses in Tatsuno City. Based in Chuo Ward, Kobe City, we welcome inquiries regarding single-item machining of mold parts, jigs, and equipment parts, as well as prototyping, small lots, and additional processing of supplied parts. We have processing experience with companies in nearby Himeji City and can also arrange visits and collection/delivery of parts in Tatsuno City. We can accommodate inquiries for specific processes, such as "I only want to request electrical discharge machining for mold parts" or "I want to add irregular holes or key grooves after hardening." For partial corrections of mold inserts or shape changes after prototype evaluation, we will review the machining standards, fixing methods, and remaining wall thickness based on the drawings and actual parts to consider feasibility. In addition to wire cutting electrical discharge machining, shape electrical discharge machining, and fine hole electrical discharge machining, we also welcome inquiries for integrated processing that combines machining and grinding. Visits can sometimes be accommodated as soon as the same day or the next business day, but adjustments will be made based on reception hours, visit locations, and the schedules of responsible personnel. Processing lead times, collection and delivery dates for supplied items, and costs will be confirmed individually.

Before creating a custom brooch | Comparing individual processing of key grooves and internal splines
We will introduce technical information that is helpful for considering processing methods. When manufacturing key grooves or internal splines in small quantities or as single pieces, preparing a dedicated broach can pose challenges in terms of cost and delivery time. If a through shape that allows for wire passage is possible, wire cutting may be a viable option. However, it is not always the case that one method is advantageous over the other. We will compare the distinctions between through and bottomed shapes, inner corner radii, tolerances, materials and heat treatment, quantities, and existing processes. The original article from Hanshin Seiko organizes the points to consider when evaluating alternatives to broaching. Please consult us along with the overall and cross-sectional drawings of the parts and any current issues you are facing.
For square holes and D-shaped holes that cannot be penetrated. Consider processing methods based on the entrance shape and the cross-section in the depth direction.

Explanation of wire cutting water processing and oil processing | Conditions to check before making a request
This article explains the differences between water processing and oil processing in wire cutting, focusing on the roles of processing fluids, fine shapes, surface roughness, and considerations for the corrosion of cemented carbide. Precision and processing costs are not determined solely by the processing fluid. It is important to organize the necessary tolerances, shapes, applications, material types, heat treatment, conditions related to rust and corrosion, as well as subsequent processes and inspection content. All wire cut electrical discharge machines from Hanshin Seiko are designed for water processing. If oil processing is specified in the drawings or order specifications, please be sure to inform us in advance. The feasibility of processing cemented carbide and meeting quality requirements will be considered by reviewing the drawings and processing conditions. For a comparison of considerations and confirmation items at the time of request, please refer to the official article in the related links.
