Surface Finish Options for Turned Parts

We offer over 10 surface finishes to ensure your parts not only meet performance standards but also achieve the desired appearance. Each finish is set to offer optimal results for your specific materials.

Name	Color	Application/Materials	Description
As-Machined	N/A	Metals / Plastics	Offers a raw surface directly from the machine with visible tool marks, suitable for functional prototypes or internal components that don’t require aesthetic appeal.
Anodizing	Clear, Black, Custom	Aluminum	Enhances corrosion resistance and surface hardness, available in various colors for aluminum parts.
Sand Blasting	Matte Gray	Metals, Plastics	Produces a smooth, matte finish by blasting fine grains of sand at the surface, ideal for improving appearance and creating a uniform texture.
Powder Coating	Custom Colors	Metals	Applies a durable, protective coating to the surface, offering both a vibrant appearance and excellent corrosion resistance.
Electropolishing	Shiny Metal	Stainless Steel, Metals	A process that removes a thin layer of material to create a smooth, shiny surface, often used for stainless steel parts to enhance corrosion resistance.
Brushing	Metallic	Metals	Gives the surface a directional satin finish, commonly used to improve the aesthetics of metal parts.
Polishing	High-Gloss	Metals, Plastics	Achieves a mirror-like finish, commonly used for both aesthetic appeal and to enhance optical clarity on transparent parts.
Electroplating	Silver, Gold, Nickel	Metals	Coats parts with a thin layer of another metal (e.g., nickel, chrome) to improve appearance and corrosion resistance.
Black Oxide	Black	Steel, Iron	Provides a thin, durable black finish for ferrous metals, improving corrosion resistance while maintaining the part’s dimensions.
Passivation	N/A	Stainless Steel	Cleans and protects stainless steel surfaces by removing contaminants and enhancing corrosion resistance.
Heat Treatment	N/A	Metals	Improves the strength and hardness of metal parts by altering their internal structure through controlled heating and cooling processes.
Passivation	N/A	Metals	A chemical process used to improve metal corrosion resistance by removing free iron from the surface.
Spraying	N/A	Metals / Plastics	A coating process that applies a fine mist of material onto a surface to improve appearance or protect against wear.
