Our website introduces "electrophoretic painting." The principle is similar to electroplating, where the workpiece is immersed in a water-soluble paint bath to form a coating. It is then cured in a heat furnace to complete the process. Even for complex shapes, a uniform coating can be achieved, resulting in a thin film of 5 to 8 micrometers, making it possible to process precision parts. Please take a look at our website. 【Features】 ■ The workpiece is immersed in a water-soluble paint bath to form a coating. ■ Cured in a heat furnace to complete the process. ■ A uniform coating can be achieved even for complex shapes. ■ Thin film coatings are possible, allowing for processing of precision parts. *For more details, please refer to the PDF materials or feel free to contact us.

On this homepage, we introduce "Parker (Manganese Phosphate Treatment)." Also known as Lubrite treatment, it generates a relatively thin manganese phosphate film of about 5μ in thickness on the surface of steel through a dipping method. Among various phosphate coatings, it is relatively hard, making it very effective for improving the wear resistance of rotating and sliding parts of steel products. Please be sure to visit our company website. 【Features】 ■ Also known as Lubrite treatment ■ Generates a relatively thin manganese phosphate film of about 5μ in thickness on the surface of steel ■ Very effective for improving the wear resistance of rotating and sliding parts of steel products ■ Resistant to weak alkalis ■ Turns yellow to brown at around 250°C and scales over 500°C *For more details, please refer to the PDF materials or feel free to contact us.

Our website introduces the "Black Dyeing Process." Our product generates a film of magnetite (Fe3O4) on the surface by immersing it in a strongly alkaline solution. It provides a glossy and elegant black finish. The alkaline dyeing method achieves a beautiful black appearance without roughening the surface of the workpiece, and the finished product is almost equal in dimensions and weight to the original, making it suitable for precision machinery. Please take a look at our website. 【Features】 ■ Immersion in a strongly alkaline solution ■ Generation of a film of magnetite (Fe3O4) on the surface ■ Glossy and elegant black finish ■ Beautiful black appearance achieved through the alkaline dyeing method ■ The film does not peel off even when the workpiece is subjected to bending or impact *For more details, please refer to the PDF document or feel free to contact us.

Our website introduces "anodizing treatment." It is used to improve the corrosion resistance, wear resistance, and decorative properties of aluminum. In Japan, the anodic oxidation film of aluminum is referred to as anodizing treatment or alumite treatment. Aluminum and its alloys are subjected to an electric current as an anode in an electrolytic solution to generate an oxide film on the surface. Please take a look at our website. 【Features】 ■ Used to improve the corrosion resistance, wear resistance, and decorative properties of aluminum ■ Generates an oxide film on the surface by passing an electric current through the item as an anode in an electrolytic solution ■ The film consists of a collection of hexagonal columns ■ The thickness of the film ranges from 4 to 10 μm ■ The film is typically formed on both the substrate side and the outer side *For more details, please refer to the PDF document or feel free to contact us.

Our website introduces "hard anodizing." It has excellent wear resistance, particularly strong against sliding wear. It is an anodic oxide film formed on aluminum materials treated with a low-temperature electrolytic bath or a special electrolytic bath with various organic acids added. The breakdown voltage of the insulation resistance has very high electrical characteristics with a highly insulating film, and it also excels in corrosion resistance. Please be sure to visit our website. 【Features】 ■ Low-temperature electrolytic bath or addition of various organic acids ■ Anodic oxide film on aluminum materials treated with a special electrolytic bath ■ Excellent wear resistance, particularly strong against sliding wear ■ Possesses electrical characteristics with a very high insulating film ■ Also excels in corrosion resistance *For more details, please refer to the PDF materials or feel free to contact us.

On our homepage, we introduce "Electroless Nickel Plating / Electroless Nickel Plating on Aluminum." Our product chemically deposits a nickel-phosphorus alloy coating without the use of electricity. It allows for a uniform film thickness. It is suitable for plating parts that require complex shapes, wear resistance, dimensional control, and corrosion resistance. Please take a look at our company website. 【Features】 ■ Nickel and phosphorus alloy coating ■ Chemically deposited without the use of electricity ■ Achieves uniform film thickness ■ Suitable for plating parts that require complex shapes, wear resistance, dimensional control, and corrosion resistance *For more details, please refer to the PDF materials or feel free to contact us.

Our homepage introduces "hard chrome." It is utilized as a white plating (flash plating) with a low wear coefficient of 1 to 5 μm or less. In general industrial terminology, chrome refers to a thickness of 5 μm or more according to JIS standards. It is used on the surfaces of parts that require strong adhesion of the coating and constant sliding, and the wear resistance of chrome plating is extremely good, surpassing that of nitrided steel. Please be sure to visit our company website. 【Features】 ■ Strong adhesion of the coating is excellent ■ Used on the surfaces of parts that require constant sliding ■ Wear resistance is extremely good and superior to nitrided steel ■ Hardness in normal conditions ranges from 750 to 1100 HV (Vickers) ■ Often used for buildup, dimensional correction, or repair purposes *For more details, please refer to the PDF document or feel free to contact us.
