Transform Your CNC Creations with Junying's Metal Finishing Services - FilipHedquist - 08-19-2024
Junying - CNClathing.com is a leading finished parts manufacturer, specializing in precision CNC machining services and an extensive range of finishing services, designed to enhance the properties and appearance of your CNC machined parts. With our expert team of workers and craftsmen, we can help you choose the perfect types of metal finishing process to meet your design goals and specifications. In this article, we will explore the different types of metal finishes we offer and their benefits.
1. Anodizing (Anodized)
Anodizing is an electrolytic passivation process that forms a thin layer of metal oxide on the exterior of CNC machined parts, increasing the thickness of the natural oxide layer, protecting the metal, adding various colors, and improving corrosion and abrasion resistance. Aluminum, stainless steel, copper, titanium, zinc, and magnesium can undergo the anodizing process.
2. Passivation
Passivation is a common chemical surface treatment method for steel and stainless steel, creating a shell for enhancing corrosion resistance or reducing chemical reactivity. Passivation of stainless steel removes free iron and ferrous contaminants on metal surfaces using an acid solution, preventing rust.
3. Plating (Electroplating)
Plating, or electroplating, uses an electric current to reduce dissolved metal cations, forming a thin coherent metal coating on an electrode. This process changes the properties of the metal surface or builds up thickness for undersized parts. Chrome plating, nickel plating, and other options are often applied at CNCLATHING.
4. Painting
Painting involves spraying paint, pigment, or color onto a solid surface as a colored protective layer. It can be applied to metal or non-metal CNC machined components of any shapes, typically used for aluminum, stainless steel, and steel alloy parts to improve aesthetic appearance and prevent corrosion or oxidation.
5. Black Oxide (Hot Blackening)
Black oxide, or hot blackening, is a chemical process forming a black conversion coating on stainless steel, copper and copper-based alloys, zinc, powdered metals, silver solder, and ferrous materials. This coating improves corrosion resistance and minimizes light reflection.
6. Polishing (Buffing)
Polishing, or buffing, rubs the surface of parts or utilizes a chemical action to produce a smooth and shiny surface. Polishing makes the surface get significant specular reflection or reduces diffuse reflection in some materials.
7. Powder Coating
Powder coating is a process that places a functional and decorative finish, applied as a free-flowing, dry powder, utilizing electrostatically and then cured under heat. This method creates a hard finish that is tougher than conventional paint, primarily used for household appliances, aluminum extrusions, drum hardware, automobile, motorcycle, and bicycle parts.
8. Heat Treatment
Heat treatment involves utilizing heating or chilling under extreme temperatures to make the metal achieve a certain state or change some characteristics. This process includes annealing, tempering, hardening, precipitation strengthening, tempering, carburizing, normalizing, and quenching.
9. Satin Finish
A satin finish provides a luster between the dull, non-shiny finish of matt materials and the bright and shiny finish of glossy finishes. The visual effect is related to the lighting of the environment, and satin metal finish remains reflective, flat, and glossy.
10. Abrasive Blasting (Sandblasting)
Abrasive blasting, or sandblasting, propels a stream of abrasive material composed of high-velocity sand-sizes particles against the metal surface under high pressure with blast equipment. This operation removes surface contaminants, cleans metals, or increases a texture, changing the smoothness or roughness of the surface.
11. Conversion Coating
Conversion coating, also known as chromate conversion, utilizes coatings on metals converted to a protective layer through chemical or electrochemical processes. It is primarily used as a corrosion inhibitor, decorative finish, or to retain electrical conductivity.
12. Tungsten Carbide Coating
Tungsten carbide coating is a thermal spray coating that involves the deposition of a thin metallic layer of tungsten carbide onto the surface of a substrate, improving wear resistance and hardness.
Choose the Best Metal Finishing Process
When selecting a metal finishing process, consider factors such as production time, cost-effectiveness, part tolerance, durability, and applications. For high-tolerance CNC milling and turning parts, it's advisable to consult with us for a free quote, as secondary metal surface treatments may change the sizes of the finished part.
