Dry film lubrication treatment (dry coating) is a lubrication process that uses solid lubricants such as molybdenum disulfide and fluoropolymer. It forms a solid lubrication film on friction surfaces, effectively reducing friction resistance, improving wear resistance (protecting components and maintaining mechanisms), and preventing abnormal noise. ■ Adoption Results Rotor section of screw compressors ■ Challenges Conventional hydraulic systems enhance the sliding properties of rotors through oil supply, but in oil-free formats, there was a challenge of low sliding properties due to friction, resulting in awkward operation. ■ Solution By applying dry film lubrication treatment to the rotor section, permanent lubrication was achieved in the relevant areas, leading to improved discharge pressure. *For more details, please download the PDF or feel free to contact us.

The "dry coating" known as "dry film lubrication treatment" is a lubrication process that uses solid lubricants such as molybdenum disulfide and fluororesins. It is optimal for lubrication under high loads, initial running-in, and in corrosive environments, vacuum conditions, and radiation exposure. We can meet your needs according to various friction conditions such as load, sliding speed, and atmosphere. Coating various bolts and screws can prevent "galling." 【Features】 ■ Prevents "galling" with coatings on bolts and screws! ■ The lubricating film has a long lifespan and is resistant to contamination from other lubricants (oils and greases)! ■ Reduces friction resistance, improves wear resistance (protects parts and maintains mechanisms), and prevents abnormal noise! ■ Ideal for sliding parts of various engine components such as automobiles and ships! *For more details, please contact us or download and view the catalog.

Molybdenum disulfide excels in lubrication in a vacuum, demonstrating superior load-bearing capacity and anti-friction properties compared to graphite, making it ideal for use as an extreme pressure lubricant. Its adoption is expanding for coating automotive engine parts that require wear resistance, seizure resistance, and reliability under harsh load conditions, contributing to friction reduction (improved fuel efficiency). 【Features】 ■ Long lifespan of the lubrication film, resistant to contamination from other lubricants (oil, grease)! ■ Reduction of friction resistance, improved wear resistance (protection of parts, maintenance of mechanisms), prevention of abnormal noise! ■ Usable in sliding parts of automobiles, ships, and construction machinery! *For more details, please contact us or download the catalog for viewing.

"Dry film lubrication treatment" is a lubrication process that uses solid lubricants such as molybdenum disulfide and fluororesin. A solid lubrication film is formed on the friction surface, which helps reduce friction resistance, improve wear resistance (protecting components and maintaining mechanisms), and prevent abnormal noises. It is used in the sliding parts of automobiles, ships, and construction machinery, providing permanent lubrication in areas where oiling is not possible. It is also ideal for lubrication under high loads, initial running-in, corrosive environments, vacuum conditions, and radiation exposure. We can accommodate various friction conditions such as load, sliding speed, and atmosphere according to your requirements. We also have a large 10-ton furnace that can accommodate 25 people standing simultaneously. *For more details, please contact us or refer to the catalog.*

"Parkarizing treatment (phosphate treatment)" is one of the representative methods of chemical treatment, which generates a thin film (on the micron order) of metal salts such as zinc phosphate on the surfaces of metals like steel and zinc. Its industrial purpose was originally to prevent rust on metal products such as tools, but in recent years, it has been widely adopted as a standard method for industrial products, including automobiles, with the aim of making paint films less likely to peel off and preventing rust from spreading even if the paint film is scratched. Aside from serving as a paint base, it is also important for facilitating plastic processing in metal drawing, forging, and extrusion processes when used in conjunction with lubricants. We are equipped with large treatment tanks (2500×2500×10000mm) as well as smaller treatment tanks to meet our customers' diverse needs. *For more details, please contact us or refer to our catalog.
