Trivia: "What is the difference between decorative chrome plating and industrial chrome plating?"
The difference between decorative chrome plating and industrial chrome plating can be simply described as a significant difference in their applications and the thickness of the coating.
Chrome plating has a beautiful shiny silver appearance and is a highly durable coating, with many chrome-plated products around us. Chrome plating is used in a wide variety of items, including faucets, accessories, and parts for cars, motorcycles, and bicycles—there are countless examples. However, chrome plating can be broadly divided into two categories: "decorative chrome plating" and "industrial chrome plating." The main purpose of decorative chrome plating is aesthetic appeal and corrosion resistance, typically applied at a thickness of about 0.1 to 0.5 μm. It is usually applied over a base layer of nickel plating or copper-nickel plating. Most of the chrome plating we encounter in our daily lives falls into this decorative category. On the other hand, the purpose of industrial chrome plating, in addition to corrosion resistance, includes wear resistance and scratch resistance, with thicknesses ranging from about 10 μm to as much as 200 μm. Utilizing the hardness and smoothness of chrome plating, it is widely used in sliding and moving parts such as cylinders, pistons, molds, rolls, and machine components. Since aesthetic appeal is not a primary concern, it is often applied directly to the material, especially when aiming to enhance corrosion resistance.

basic information
To summarize the features: <Decorative Chrome Plating> - The main purposes are corrosion resistance and aesthetic appeal. - The plating thickness is very thin, around 0.1 to 0.5 μm. - It is often applied after nickel or copper plating on the substrate. <Industrial Chrome Plating> - The main purposes are wear resistance, scratch resistance, and release properties. - The plating thickness is generally thick, ranging from 10 to 200 μm. - When corrosion resistance is not a primary concern, it is often applied directly to the base material. Our company specializes in industrial chrome plating among these two types. We handle a wide range of products, primarily precision rolls, as well as molds and various machine parts. In particular, regarding rolls, we have a subsidiary roll processing factory, allowing us to carry out consistent production in-house from design, material selection, cutting, and canning to surface treatment and final surface finishing. We can accommodate various types of rolls, including jacket rolls, knife rolls, coater rolls, calendar rolls, and elastic rolls, among others. Additionally, in terms of surface treatment, we offer not only standard hard chrome plating but also our original surface treatment technologies, such as "Tef-Lock" and "Chroamore," enabling us to meet a wide range of needs.
