Precision Surface Finishes

CNC TUOWEI  Machining offers a variety of surface finishes to enhance durability, aesthetics, and performance. Choose from anodizing, powder coating, polishing, and more for precision-engineered parts.

Surface Finishing Sheets Metal Fabrication

Surface finishes for sheet metal fabrication enhance durability, improve corrosion resistance, and refine aesthetics, allowing parts to meet both functional and visual requirements.

Polishing

 Polishing smooths the surface, providing a high-gloss finish that improves both appearance and resistance to wear.

Anodizing

This process adds a protective oxide layer to metal surfaces, increasing corrosion resistance and enhancing aesthetic appeal.

Bead Blasting

Bead blasting involves spraying fine beads onto the surface to create a smooth, matte finish with a uniform texture.

Electroplating

Electroplating adds a thin metal coating to a surface, offering enhanced corrosion resistance, wear protection, and improved conductivity.

Lapping

Lapping is a precision process that improves surface flatness and smoothness, reducing surface roughness for high-tolerance applications.

Shot Peening
