Smooth the surface of stainless steel for a glossy finish! A sufficient electrolytic polishing forms an oxide film.
"Electropolishing" is a polishing process that involves filling an electrolytic cell with an electrolyte solution and passing direct current through the metal being polished, causing its surface to dissolve. By utilizing this technology to polish stainless steel, a clean and shiny surface can be achieved, and the increased chromium concentration makes it more resistant to rust. Due to these processing characteristics, it is now being adopted in advanced fields such as the manufacturing of construction materials that require gloss, pharmaceuticals and food products that demand high cleanliness, as well as in the production of semiconductors and liquid crystals. **Features** - Smooths out the surface irregularities of stainless steel to achieve gloss and excellent corrosion resistance. - The surface is smooth and resistant to the attachment of impurities. - Buff polishing reveals previously invisible scratches and pinholes. - Sufficient electropolishing forms an oxide film. - Sufficient electropolishing leaves concentrated chromium on the surface. - Electropolishing creates a passive film that is resistant to rust. *For more details, please refer to the PDF document or feel free to contact us.*

Make the stainless steel surface even more beautiful! Electrolytic polishing that can create differences in gloss by adjusting current density and electrification time!
"Electropolishing of Stainless Steel Products" is a technique that involves immersing stainless steel products in an electrolytic solution and applying direct current voltage to induce electrolysis at the interface between the solution and the metal. This process utilizes the metal dissolution reaction at the anode, resulting from the electrochemical reaction, to polish the metal surface. Instead of mechanically removing the surface like hairline processing or buff polishing, it preferentially dissolves the protruding areas where electricity is concentrated, resulting in a smooth surface. 【Features】 - Improvement and modification of stainless steel surfaces - Enhanced cleanability - Adjustment of gloss level *For more details, please request documentation or view the PDF data available for download.
A clear explanation of the differences between denken and electropolishing, as well as passivation and other related topics!
The method commonly referred to as "Denken," which is performed by our hometown processing partners by default, differs from "electrolytic polishing." However, the effect of "improving corrosion resistance" is the same. First, "Denken" refers to "Super Shiner A2," which is produced by Chemical Yamamoto Co., Ltd. The slogan for Super Shiner A2 is "SUS304 achieves corrosion resistance comparable to SUS316." So, why does using Super Shiner A2 improve corrosion resistance? The key phrase is "ultra passivation." *For more detailed information, you can view the related links. For more details, please download the PDF or feel free to contact us.*
Buff polishing and welding, which are part of the preprocessing, can be performed in-house!
At Sakai Stainless, we have established multiple specialized electro-polishing factories, equipped with various cleaning facilities and purification systems to meet diverse needs. After the electro-polishing process, we can address cracks, deep scratches, and pinholes by adjusting the process flow. Additionally, we can perform large-scale electro-polishing (up to 30 tons) in-house, along with welding, canning, and buff polishing, allowing us to respond quickly to quality and delivery deadlines. Furthermore, by storing finished products in a mobile pressurized booth after electro-polishing, we can prevent the adhesion of airborne dust. 【Features】 ■ Large temperature-controlled pure water jet cleaning ■ Storage available in a large finished product pressurized booth (6500×6000×2400) ■ Small items stored in a Class 10000 clean bench ■ In-house production of electro-polishing jigs ■ Equipped with oil content measuring devices and immersion tanks (3600×5000×1200) ■ On-site electro-polishing available for existing products *Please feel free to contact us for more details.
Multiple specialized electro-polishing factories established! Responding to diverse needs along with various cleaning equipment and clean facilities.
In the manufacturing sites of pharmaceuticals and food products, stainless steel products are mainstream, and particularly in pharmaceutical manufacturing, a system compliant with GMP is required, making "electropolishing" an important option. Sakai Stainless has established multiple specialized electropolishing factories, equipped with various cleaning facilities and cleanroom facilities to meet diverse needs. **Strengths of Sakai Stainless in Electropolishing** - Ability to address cracks, deep scratches, and pinholes discovered after the electropolishing process by adjusting the workflow. - Capability for large-scale electropolishing (up to 30 tons) to be performed in-house alongside welding, canning, and buffing. - Quick response to quality and delivery times. - Addressing the adherence of floating dust by storing finished products in a mobile pressurization booth after electropolishing. *For more details, please refer to the related link page or feel free to contact us.*
Many voices of joy say that corrosion resistance has improved and product lifespan has been extended! We can accommodate everything from small items to long products.
"Electrolytic polishing" is a polishing method aimed at smoothing surfaces by passing electricity through an electrolyte solution to dissolve metal ions from the metal surface. Our company owns two fully automated lines, allowing us to finish a large number of products in a short delivery time, accommodating both small and large lots. By electrolytically polishing stainless steel products, which are originally resistant to corrosion, we can enhance their corrosion resistance, decorative quality, and aesthetic appeal, thereby adding value to the products. 【Features】 ■ Two fully automated lines capable of handling both small items and long materials ■ Ability to perform combined treatments with passivation, shot blasting, and pickling ■ Capable of accommodating detailed requests with hand-held electrolytic polishing machines ■ Adjustable polishing width according to customer requirements ■ Advanced cleaning technology developed through accumulated know-how *For more details, please refer to the PDF document or feel free to contact us.

A small surface area makes it difficult for bacteria and viruses to get into gaps! Introducing electro-polishing that minimizes fingerprints.
"BEP (Blind Electro Polishing)" is a method developed to create a clean surface based on electro-polishing for stainless steel parts. Typically, electro-polishing is used as a treatment that produces a glossy finish, but this method results in a matte surface on stainless steel. The fine irregularities on the surface scatter light, making fingerprints less noticeable. Additionally, compared to electro-polishing and buff polishing, it provides a warmer texture. 【Features】 ■ Fingerprints are less noticeable ■ Significantly improved corrosion resistance ■ Three times the antibacterial properties of buff-polished pipes ■ High cleanliness is achieved ■ Smaller surface area, making it difficult for bacteria and viruses to penetrate gaps *For more details, please refer to the PDF document or feel free to contact us.

Electropolished finish that enhances the sanitary properties and corrosion resistance of stainless steel containers.
The finishing of each series is typically done with a standard buff polishing finish, except for some products, but electropolishing is possible to enhance sanitary properties and corrosion resistance. Electropolishing is a method that smooths the surface of stainless steel by chemically and electrically dissolving metal ions from the metal surface in an electrolytic solution. This results in a uniform and high-quality finish. Electropolishing can be applied to almost all parts that come into contact with liquids, including containers and sanitary components.
