Surface Finishes

Surface Finishes Anodization
Anodization provides excellent corrosion resistance to machined parts, improving the hardness and wear-resistance of the surface while dissipating heat. Anodization is the most common surface treatment for painting and priming as it provides a high quality surface finish. RapidDirect offers two types of anodization: Type II, which is corrosion resistant; and Type III, which is thicker and adds a wear-resistant layer. Both anodization processes allow for a broad range of color finishes.
Anodization (Type II or Type III)
Surface Finishes Bead Blast
Bead blasting consists of blowing small glass beads against the surface of the machined part in a controlled manner. This technique results in a smooth surface with a matte texture. In bead blasting, various materials—such as sand, garnet, walnut shells and metal beads—are used to clean parts or prepare them for subsequent surface treatments.
Bead Blast
Surface Finishes As-Milled
As-milled surface finishes offer the fastest turnaround for parts. The surface finish of an as-milled part is comparable to 125 µin Ra, while the requirements can be increased to 63, 32, or 16 RA µin. Minor tool marks might still be visible on the final part.
In the powder coating process, powdered paint is sprayed directly onto the machined part, which is then baked in an oven, forming a durable, wear-resistant and corrosion-resistant layer. A wide variety of color options are available in the powder coating process.

The table below summarizes the standard tolerances of the parts produced by certified RapidDirect. Tolerances up to .0008” (0.020mm) are available upon request.

Tips: Tighter tolerance are examined on a case by case basis with your technical drawings.


Rapid Tooling

Rapid Tooling

Our CNC machining service is ideal for rapid tooling and can be used with almost any material. At RapidDirect, we specialize in the production of high quality tools used in injection molding and other tooling applications.

Rapid Prototyping

Rapid Prototyping

CNC Machining is ideal for prototyping applications for a number of reasons: it is compatible with a broad range of cost-effective materials, it produces precise parts and prototype turnaround times are rapid. We work with our customers to design and produce prototypes that meet their manufacturing requirements and quality standards.

End-Use Production

End-Use Production

CNC Machining is commonly used for end-use production because of its precision, high-quality finishes and broad material compatibility. At RapidDirect, we offer customers a range of end-use materials, including plastics, aluminium and brass. We also provide the option to work with custom raw materials.
