Anodizing and hard anodising: Anodizing has the ability to enhance the corrosion resistance of metal surfaces, increase surface hardness, and improve abrasion resistance, as well as improve appearance.Anodizing is mainly divided into two types: The surface of anodized parts is uniform and beautiful, with good corrosion and wear resistance, and a wide range of colors are available, including black, natural, green, red, titanium and so on.

Hard anodising is a modified form of anodizing, where a special process is used to make the oxide layer denser and harder, providing superior corrosion and wear resistance. Although suitable for functional applications, color options are relatively limited, usually only available in natural or black.

Metal Plating: Metal plating is a common surface treatment method, including galvanizing and chrome plating. These methods not only improve the appearance, but also increase the corrosion and abrasion resistance of the parts, and are widely used in areas such as automotive parts and lighting manufacturing.

Hot treatment (e.g. of metal): Heat treatment is a method of improving the hardness, strength and wear resistance of a part by heating the metal to a certain temperature and then cooling it rapidly. This method is widely used in the manufacture of molds and tools.

Powder Coatings: Powder coatings are solid powders that are uniformly sprayed onto metal surfaces and then melted and cured at high temperatures to form a strong protective layer.This method not only makes the parts more beautiful, but also has good corrosion and abrasion resistance, and is widely used in machinery and automotive fields.

Laser Carving: Laser engraving is a technology of engraving or marking the surface of the material by laser beam, which is commonly used in the customization of personalized product LOGO or special patterns, etc.
