Surface Finish and Post-Processing Options
We offer a variety of cnc machining finish options to meet your part requirements. Common finishes include anodized, sandblasted, powder coat, electroplating, and polished.
Anodized
Anodizing is an electrochemical process that transforms the metal surface into a durable, corrosion-resistant anodic oxide film. This technique is commonly applied to aluminum, enhancing its corrosion resistance, wear resistance, and hardness to protect the metal surface. It is widely used in industries such as aerospace, automotive, construction, consumer electronics, machinery parts, and precision instruments.
Sandblasted
Sandblasting, also known as abrasive blasting, is a process in which abrasive particles are strongly pushed under high pressure to hit the surface to smooth rough surfaces and roughen smooth surfaces, which is usually applied to aluminum and stainless steel materials. In addition, due to the high jetting force, this process is not applicable to parts with a material thickness lower than 1.0MM, which can easily cause deformation.

Powder Coat
Powder coating is a precision finishing process used to apply a dry, powdery coating onto surfaces (usually metal) and then cured under heat or ultraviolet light. This increases the durability of parts, making their surfaces more resistant to scratches, fractures, fading, and wear. It also offers a variety of colors and textures, including matte, satin, high-gloss, and textured finishes. This process is particularly suitable for automotive components, outdoor furniture, appliances, and metal railings.
Electroplating
Electroplating is a process that uses an electric current to deposit a thin layer of metal onto an object. The advantages of electroplating include enhanced corrosion resistance, increased hardness, reduced friction, improved electrical conductivity, and enhanced aesthetics. This makes it the preferred surface treatment process for the automotive, electronics, and aerospace parts industries.

Polished Finish
Polishing is a surface treatment process that forms a highly reflective, smooth surface on metal materials. This finishing process involves using abrasives to gradually polish the surface to a mirror-like appearance. It offers aesthetics, corrosion resistance, ease of cleaning, and a mirror effect. It is typically suitable for decorative parts where a high level of appearance is required.
