"Industrial hard chrome plating" significantly improves wear resistance when applied to machine parts and tools due to its high hardness. Molds and dies benefit from improved release properties, resulting in more aesthetically pleasing products and a substantial extension of mold life. Additionally, when industrial chrome plating reaches a thickness of 30μ to 50μ, small pores and cracks that connect to the base material are completely sealed, providing excellent corrosion resistance. [Examples of Applications] - Various tower tanks - Heat exchangers - Valves - Flanges - Pumps *For more details, please refer to the PDF document or feel free to contact us.

• Plating Equipment

"Industrial hard chrome plating" significantly improves wear resistance when applied to machine parts and tools due to its high hardness. Mold types benefit from improved release properties, resulting in more aesthetically pleasing products and a substantial increase in mold lifespan. Additionally, while general plating can peel off due to friction or heating, industrial chrome plating is almost alloyed with the material, and even when heated to 600°C in the air, the adhesion of the plating is not affected at all. [Examples of Applications] - Engine parts (can be used in high-temperature oxidation environments below 400°C), etc. *For more details, please refer to the PDF materials or feel free to contact us.

"Industrial hard chrome plating" significantly improves wear resistance when applied to machine parts and tools due to its high hardness. Molds have better release properties, resulting in more aesthetically pleasing products, and the lifespan of the molds is greatly extended. Furthermore, the most important factors for wear resistance are hardness and the coefficient of friction. Industrial chrome plating shows values of Vickers hardness between 800 and over 1000, indicating that it is much harder compared to heat-treated steel and nitrided steel. [Examples of Applications] - Cylinders - Rolls - Various molds - Gauges *For more details, please refer to the PDF document or feel free to contact us.

For those considering new production of parts that have been used for many years, we recommend plating repairs. When it comes to new production, it takes a considerable amount of time from material procurement to completion. However, in the case of repairs through plating, it is possible to fix the desired areas by polishing out scratches, applying a thick hard chrome plating, and finishing with polishing. Additionally, since hard chrome plating is harder than the base material itself, it becomes more resistant to wear compared to conventional methods.

We would like to introduce our "Electroless Nickel + Chrome Plating." The industrial chrome plating film retains micro-cracks, which help to hold oil and contribute to improved lubrication. However, if these micro-cracks penetrate through to the substrate, corrosion can progress due to the liquid that enters through them. To address this, applying a highly corrosion-resistant electroless nickel plating as a base layer under the chrome plating allows us to maintain the advantages of chrome plating (such as hardness and wear resistance) while achieving a plating with even higher corrosion resistance. 【Features】 ■ Improved corrosion resistance expected from the two-layer plating ■ Applicable not only to iron materials but also to aluminum materials ■ Processable regardless of roll shape ■ Suitable for overhauls as it allows for stripping treatment without removing the base material ■ Full surface treatment possible, providing rust prevention effects for the entire product ■ Uniform thickness compared to electroplating, reducing variation in film thickness *For more details, please refer to the PDF document or feel free to contact us.
