マルイ鍍金工業 List of Products and Services

Typically, the acid cleaning of SUS materials is entrusted to specialized contractors, who immerse the products in an "acid cleaning tank" to remove welding scale and surface dirt. Therefore, depending on the size of the product, issues such as "not fitting in the tank" may arise, and for larger products, transportation issues may also come into play. This "on-site acid cleaning" is carried out by Marui Plating Industry staff who travel to the site to perform the cleaning, thus resolving these problems. The appearance is similar to immersion acid cleaning, as a specialized acid cleaning agent is "applied" overall, making it less likely to have unevenness. Additionally, since it is not a brush application method, there will be no brush marks. However, it is important to note that surface scratches and dents cannot be removed by acid cleaning, and extreme welding slag or discoloration (if it has become stained over time) may not be removable. Marui Plating Industry will responsibly collect all waste liquid (concentrate). For more details, please contact us or refer to our catalog.

In on-site acid cleaning work, a dedicated acid cleaning agent is "applied" overall, similar to immersion acid cleaning, which makes it less likely to have unevenness. Since it is not a brush application method, there will be no brush marks. In on-site cleaning work, alkaline degreasing cleaning, pure water cleaning, and passivation treatment are performed. Alkaline degreasing cleaning is a cleaning process that removes oils and fats, and there is also electrolytic degreasing. Pure water cleaning is a process that uses pure water after degreasing cleaning, providing a higher level of cleanliness. Passivation treatment is a cleaning process that enhances corrosion resistance by performing passivation treatment after degreasing cleaning. Marui Plating Industry Co., Ltd. will take full responsibility for the collection of waste liquid (concentrate). For more details, please contact us or refer to the catalog.

The devices and products used in various manufacturing sites have experienced a decline in surface cleanliness compared to their initial installation state due to years of use. This significantly impacts the quality, yield, and productivity of product manufacturing. Marui's regeneration cleaning for plating greatly contributes to the regular cleaning maintenance of these devices and products. Additionally, this cleaning can also be performed on-site.

Electrolytic polishing is a method that immerses products in a chemical solution and polishes them through electrochemical reactions. It polishes the metal surface by performing electrolysis between the product and the electrode facing it. There is no processing alteration, it is not affected by heat, and it excels in smoothness, corrosion resistance, cleanability, cleanliness, and non-adhesiveness.
