武田鍍金工業所 List of Products and Services

Our company conducts chemical treatments for rust prevention and surface finishing. Chemical treatment refers to a method of surface treatment that involves chemical reactions such as sulfuration or oxidation in a solution, forming a film of sulfides or oxides on the surface to enhance corrosion resistance and improve adhesion with coatings. Additionally, for surface finishing, we offer options such as "buff polishing mirror finish," "matte finish," and "hairline finish," which can achieve a mirror-like surface without altering the shape. Finishing treatments can also be combined with various types of plating to enhance functionality and upgrade appearance, catering to a wide range of purposes. 【Various Surface Treatments】 ■ Parkerizing ■ Alkaline Coloring ■ Buff Polishing ■ Matte Treatment ■ Hairline Finish *For more details, please refer to the PDF document or feel free to contact us.

"Electroless nickel" is a type of electroless plating that deposits a metallic nickel film on the substrate by immersing it in a plating solution, where electrons are released through the oxidation of reducing agents contained in the solution, rather than through electrical current. It is suitable for complex shapes and items that require precise finishing dimensions, as it produces a uniform coating thickness. Additionally, it offers superior corrosion resistance and wear resistance compared to electroplated nickel. 【Features】 - Suitable for complex shapes and items with precise finishing dimensions - Superior corrosion resistance and wear resistance compared to electroplated nickel *For more details, please refer to the PDF document or feel free to contact us.*

"Electroplating" is a surface treatment technology that involves immersing an item in a solution containing metal cations that you want to adhere to the surface of the item, using the item as a cathode to deposit the metal electrically onto the cathode surface. "Zinc plating," which is widely used for electroplating due to its low cost and high corrosion resistance, is commonly applied as a rust prevention and decorative surface treatment for iron in the automotive, electrical, electronic, construction, and other industries. Additionally, there are copper, nickel, and chrome, which are typically applied for decorative purposes and are usually done in conjunction with buff polishing. [Features (Zinc Plating)] ■ Glossy Chromate (Unichrome): Blue-silver white ■ Colored Chromate (Chromate): Mainly yellow with iridescent colors ■ Black Chromate (Black Unichrome): Black ■ Trivalent Chromate: A treatment method that does not use hexavalent chromium in the treatment solution *For more details, please refer to the PDF document or feel free to contact us.

"Industrial (hard) chrome" is a representative industrial electroplating with many mechanical properties. It is a highly reliable surface treatment for wear resistance. It has high hardness, excellent wear resistance, and also outstanding heat and corrosion resistance. There is also a thin plating called hard flash, which is performed in a very short time for the purpose of activating the base material or coloring. 【Features】 ■ Suitable for wear resistance ■ High hardness and excellent wear resistance ■ Outstanding heat and corrosion resistance ■ Hard flash: Thin plating performed for the purpose of activating the base material or coloring *For more details, please refer to the PDF document or feel free to contact us.

"Anodizing" is a general term for the technology that oxidizes and coats the surface of aluminum by using water electrolysis in a strong acid, primarily as an anode, and is also referred to as anodic oxidation treatment. It is performed to improve the corrosion resistance and wear resistance of aluminum, as well as for decorative purposes. By applying this coating, it also becomes an insulator and does not conduct electricity. 【Features】 ■ Improved corrosion resistance and wear resistance ■ Becomes an insulator through coating ■ Standard anodizing (white/black): A common treatment performed in a sulfuric acid bath ■ Hard anodizing (gray): Processed in a low-temperature electrolytic bath to create a thick, hard coating *For more details, please refer to the PDF document or feel free to contact us.
