Casters need to run in a variety of complex environments, the corrosion resistance of the metal surface is particularly important. Now on the market, the most commonly used treatment methods are galvanization and electrophoresis, while Zhuo Ye manganese steel casters after full consideration, but choose the spraying treatment, and why is this? Next, I will start from these three processes, detailed analysis for you!
1、Spraying process
The spraying process is a process of spraying paint onto the surface of an object and is commonly used for the surface treatment of various metal products. The process has the following main advantages:
The spraying process allows for fast and efficient surface coating. Compared with the traditional brushing process, the spraying process has higher coating speed and better coating effect, which can greatly improve production efficiency.
A wide variety of coatings are available for the spraying process, and coatings suitable for different metal materials and process requirements can be selected to achieve better anti-corrosion, anti-oxidation, anti-UV and aesthetic effects.
The coatings used in the spraying process have good corrosion and abrasion resistance, and can protect the metal surface from chemical, physical and environmental factors such as erosion and damage.
The spraying process can be applied to the surface coating of most metal materials, such as iron, aluminum, copper, zinc, stainless steel, etc.
In the medium salt spray test (NSS), the appearance grade of spray plastic treatment can reach grade 9 by the authority testing.
2、Electrophoresis process
The electrophoresis process is a coating process using the principle of electrophoresis, where the paint adheres to the charged surface of the workpiece. The process has the following main advantages:
The coating of the electrophoresis process is uniform, dense, non-porous, with good coating quality, which protects the metal surface from erosion and damage by chemical, physical and environmental factors.
A wide range of coatings used in the electrophoresis process allows the selection of coatings suitable for different metal materials and process requirements, thus achieving better anti-corrosion, anti-oxidation, anti-UV and aesthetic effects.
The electrophoresis process can be automated to improve production efficiency and reduce coating costs.
In the medium salt spray test (NSS), the conventional electrophoresis treatment has an appearance grade of 5 as tested by the authority.
3、Galvanizing process
The galvanizing process involves coating the surface of steel with a layer of zinc, thereby improving the corrosion resistance of steel products. The process has the following main advantages:
The galvanizing process provides full coverage and is able to cover all parts of the metal surface, including the interior and difficult to coat areas. As a result, coatings from the galvanizing process have better corrosion resistance.
The zinc used in the galvanizing process is self-healing, meaning that when the coating is scratched or damaged, the zinc will flow on its own to fill the damaged area, thus extending the life of the coating.
In the medium salt spray test (NSS), the conventional galvanized treatment has an appearance rating of 3 by the authorities.
| Process | Painting efficiency | Range of application | Appearance grade |
| Spraying process |
High | Most metals | Grade 9 |
| Electrophoresis process | Medium | Most metals | Grade 5 |
| Galvanizing process |
Low | Steel products | Grade 3 |
From the above table, we can see that the spraying process has the highest coating efficiency and the highest appearance grade. In the complex use environment, especially corrosion resistance, the spraying treatment is far greater than the traditional galvanizing and electrophoresis treatment, which is the biggest reason for Zhuo Ye to choose the spraying treatment for manganese steel casters.
With quality to create a brand, Zhuo Ye manganese steel casters always adhere to quality, put product quality first, and adhere to a highly standardized production process, to achieve Zhuo Ye manganese steel casters labor-saving, durable characteristics, and ultimately committed to the sacred mission of "make handling more labor-saving, make the enterprise more efficient".
