What is Surface Finishing

Surface finishing refers to the processes and techniques used to alter the surface of a manufactured product to achieve a particular appearance, texture, and functionality. Surface finishing methods can include polishing, plating, painting, anodizing, and more, and are used to improve qualities such as adhesion, corrosion resistance, hardness, conductivity, and other characteristics of industrial components.

Our Finishing Services

Comely CNC offers types of surface finishing used in manufacturing. Here are some of the most common types and brief descriptions of each:

• Polishing: 
This involves using abrasives to create a smooth, shiny surface.

• Anodizing: 
This process involves creating a protective oxide layer on the surface of metals such as aluminum to improve its durability, corrosion resistance, and aesthetic appeal.

• Plating: 
This involves coating the surface of a material with a layer of metal to improve its appearance, durability, or conductivity.

• Powder coating: 
This involves applying a dry powder to the surface of a material, which is then baked to create a durable, attractive finish.

• Sandblasting: 
This involves using high-pressure air or water to blast abrasive materials onto the surface of a material to remove imperfections and create a textured finish.

• Electropolishing: 
This is an electrochemical process that involves removing a thin layer of material from the surface of a metal to improve its smoothness and shine.

• Chemical etching: 
This involves using chemicals to selectively remove material from the surface of a material, creating a pattern or design.

• Painting: 
This involves applying a coating of paint or other liquid material to the surface of a material to improve its appearance or durability.

What Are The Benefits of Surface Finishing for your Parts?

• Improved Ergonomics
Surface finishing can improve the overall usability of your products. By introducing certain textures to the surface of your part, you can enhance its functionality and application. Our most common texturing operations are used to improve the handling and grip of end-use parts.

• Strength and Hardness
Finishing options like plating, anodizing, and electrophoresis can improve the surface hardness and strength of finished parts.

• Part Protection
Our finishing solutions can also protect your part’s surface from everyday wear and tear, abrasion, rust, and operational extremes. We use anodizing to increase the natural oxide layer on parts and make them anti-corrosion. Plating solutions can also help improve the lifespan of a part that is to be deployed in trying work environments.

• Cosmetic Excellence

The basic essence of our surface finishing operations is to enhance your part’s cosmetic excellence and elaborate the beauty and aesthetics of your product. While parts can be left “as manufactured,” painting, coating, polishing, and blasting can help achieve superior cosmetics that increase the overall quality of prototypes and end parts.
