Surface Finishing FAQ
Which finish provides the best hardness for aluminum?
Hardcoat Anodizing (Type III) offers the highest hardness for aluminum, creating a ceramic-like surface that is extremely resistant to wear and scratches.
Can PVD be applied to any material?
PVD is most effective on conductive materials like stainless steel and titanium. For plastics, we usually recommend Vacuum Plating to achieve a similar metallic look.
Does surface finishing affect part tolerances?
Yes. Finishes like Powder Coating can add 50-100 microns, while Anodizing or Black Oxide typically add less than 5 microns. It is critical to factor this into your CAD design.
