Electroless Nickel Plating<\/td>\nA surface treatment that forms a protective film through chemical reactions without using electricity.\nIt enables uniform coating even on complex shapes, maintains high dimensional accuracy, and is compatible with various materials including insulators.\nWidely used across industries due to its excellent performance.<\/td>\n\"Electroless<\/td>\n<\/tr>\n
Black Oxide<\/td>\nA surface treatment that forms black rust on steel surfaces to protect the underlying material.\nIt suppresses the formation of red rust and enhances corrosion resistance.\nIts refined appearance and low processing cost make it suitable for both industrial products and interior applications.<\/td>\n\"Black<\/td>\n<\/tr>\n
Trivalent Chromate (clear)<\/td>\nA surface treatment that forms a chromium layer on metal surfaces through electrochemical reaction.\nThe chromium film provides high hardness, excellent wear resistance, corrosion resistance, and a mirror-like gloss.\nThe resulting layer significantly improves the durability and appearance of the base material.\nThe white tone refers to the color of the film formed after chemical treatment.<\/td>\n\"Trivalent<\/td>\n<\/tr>\n
Trivalent Chromate (Black)<\/td>\nA surface treatment that forms a chromium layer on metal surfaces through electrochemical reaction.\nThe chromium film offers high hardness, wear resistance, corrosion resistance, and a glossy black finish.\nThe coating enhances both the durability and visual quality of the material.\nThe black tone is the color of the film that appears after chemical treatment.<\/td>\n\"Trivalent<\/td>\n<\/tr>\n
Hard Chrome Plating (Flash Plating)<\/td>\nA surface treatment developed for industrial applications that achieves superior hardness, wear resistance, and corrosion resistance compared to traditional chromate processing. The resulting film reaches a hardness of HV700\u20131000, significantly enhancing the durability of sliding components.<\/td>\n\"Hard<\/td>\n<\/tr>\n
Low Temperature Black Chrome<\/td>\nAn electroplating process performed at low temperatures that provides durability comparable to hard chrome. It offers excellent corrosion, wear, and heat resistance, along with strong adhesion that minimizes the risk of coating cracks.<\/td>\n\"Low<\/td>\n<\/tr>\n
Phosphate Coating<\/td>\nA surface treatment that forms a phosphate layer on metal surfaces to improve rust resistance, wear resistance, and paint adhesion. It is widely used in automotive and consumer electronics components requiring long-term reliability.<\/td>\n\"Phosphate<\/td>\n<\/tr>\n
Nitriding<\/td>\nA thermal process that diffuses nitrogen into the metal surface to increase hardness. It enhances wear, fatigue, and corrosion resistance while minimizing distortion, making it suitable for automotive parts, machinery components, and molds.<\/td>\n\"Nitriding\"<\/td>\n<\/tr>\n
Clear Anodize<\/td>\nA process that forms a thick alumina layer on aluminum surfaces to improve corrosion resistance, wear resistance, electrical insulation, and dyeability. It is highly decorative and can be dyed in various colors. The white anodized finish is colorless and transparent, resembling the natural silver-white of aluminum.<\/td>\n\"Clear<\/td>\n<\/tr>\n
White Anodizing (Matte Finish)<\/td>\nA surface treatment that combines anodizing with blasting and chemical texturing to create fine surface irregularities, reducing light reflection and producing a matte finish. It is commonly used in optical equipment. The white finish is colorless and transparent, close to the natural aluminum tone.<\/td>\n\"White<\/td>\n<\/tr>\n
Black Anodize<\/td>\nA surface treatment that forms a thick alumina layer and enhances corrosion resistance, wear resistance, insulation, and dyeability. After treatment, the surface is dyed black, making it suitable for decorative and functional applications.<\/td>\n\"Black<\/td>\n<\/tr>\n
Black Anodize (matte)<\/td>\nA surface treatment that includes anodizing, blasting, and chemical texturing to reduce surface reflectivity and achieve a matte black finish. It is widely used in optical components where low brightness is required.<\/td>\n\"Black<\/td>\n<\/tr>\n
Hard Anodize (clear)<\/td>\nA process performed in cold sulfuric acid to form a thick, hard alumina film with improved hardness and wear resistance compared to standard anodizing. It is used in industrial fields such as automotive and aerospace, where both durability and lubricity are required. The color tone ranges from yellow-brown to natural aluminum.<\/td>\n\"Hard<\/td>\n<\/tr>\n
Hard Anodizing (White Matte Finish)<\/td>\nA surface treatment that combines hard anodizing with blasting and chemical texturing to reduce light reflection and produce a matte finish. It is used in optical components and has a color tone similar to yellow-brown or natural aluminum.<\/td>\n\"Hard<\/td>\n<\/tr>\n
Red Anodize<\/td>\nA surface treatment that forms a thick alumina layer to improve corrosion resistance, wear resistance, insulation, and dyeability. After anodizing, the surface is dyed red, making it suitable for decorative applications.<\/td>\n\"Red<\/td>\n<\/tr>\n
Gold Anodize<\/td>\nA surface treatment that forms a thick alumina layer with enhanced corrosion resistance, wear resistance, insulation, and dyeability. The surface is dyed gold after anodizing, making it ideal for decorative purposes.<\/td>\n\"Gold<\/td>\n<\/tr>\n
Passivation<\/td>\nA surface treatment that forms an ultra-thin oxide coating on the metal surface to enhance corrosion resistance. It prevents rust from forming and contributes to a more uniform appearance and improved cleanliness.<\/td>\n\"Passivation\"<\/td>\n<\/tr>\n
Trivalent Chromate Passivation (SurTec 650)<\/td>\nIt is an alternative technology to the conventional alodine treatment using hexavalent chromium and is a surface treatment developed to comply with environmental regulations (e.g., RoHS). It has excellent corrosion resistance and, unlike anodized aluminum, retains its conductivity. It is often used in the parts and housings of test equipment around electronic boards and communication equipment.<\/td>\n\"Trivalent<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
