There are various surface treatment methods for metal machinery sheet metal parts, and each method will have a different impact on the performance and appearance of the sheet metal parts. Here are some common surface treatments and their effects:
Method: In the electroplating solution, charged ions adhere to the surface of the product under the action of the electric field to form a coating.
Impact: Electroplating can increase the corrosion resistance of sheet metal parts, giving them better durability and aesthetics. At the same time, the electroplating layer can also provide a certain hardness and enhance the wear resistance of sheet metal parts.
Powder spraying (plastic spraying):
Method: Spraying is a coating process that uses a corona discharge to adhere powder-based paint to the work surface. After the powder is sprayed, it is hot melted or cured to form a coating on the work surface.
Impact: Powder spraying can give sheet metal parts a uniform and beautiful coating, increasing their corrosion resistance and wear resistance. In addition, powder coating can also adjust the color and texture according to needs to enhance the appearance of sheet metal parts.
Oxidation:
Method: Oxidize the metal on the workpiece to form a deep protective film on the surface of the workpiece to increase the corrosion resistance of the workpiece. There are usually two methods: chemical oxidation and anodizing.
Impact: Oxidation treatment can enhance the corrosion resistance and wear resistance of sheet metal parts, while improving the hardness and gloss of its surface. Anodizing can also form a dense oxide film on the surface of sheet metal parts, further improving its corrosion resistance.
Brushed:
Method: Surface wire drawing is a surface treatment method that forms lines on the work surface by grinding the product to reproduce the decorative effect.
Impact: Brushing treatment can form unique texture and decorative effects on the surface of sheet metal parts, improving the grade and aesthetics of the product. At the same time, wire drawing treatment can also increase the wear resistance and anti-slip properties of sheet metal parts to a certain extent.
Imprint:
Method: Imprint processing refers to arranging thin plates between the upper and lower molds, changing the thickness of the material under pressure, filling the convex and concave parts of the mold cavity with the pressed material, and filling it with concave and convex micro-lines on the surface of the workpiece. Forming bumpy bats, patterns and patterns.
Impact: Imprinting processing can form various patterns and textures on the surface of sheet metal parts, increasing the aesthetics and personalization of the product. At the same time, the embossing treatment can also improve the hardness and wear resistance of sheet metal parts to a certain extent.
Paint:
Method: Through spraying, high-temperature sintering and other methods, coatings of various colors are applied to the surface of the material to beautify the appearance and improve corrosion resistance. There are generally liquid baking coatings and powder baking coatings.
Impact: Baking paint treatment can form a uniform and beautiful coating on the surface of sheet metal parts, increasing its corrosion resistance and wear resistance. At the same time, the color and gloss of the baking paint coating can be adjusted according to needs, giving the sheet metal parts a better appearance.
Different surface treatment methods have different effects on the performance and appearance of sheet metal parts. Choosing an appropriate surface treatment method requires comprehensive consideration based on the specific needs and uses of the product.
