Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Industrial Surface Finishing & Coating Services.

What is the difference between Type II and Type III hard anodizing? +
Type II (decorative/standard) produces a 10–25µm oxide layer suitable for cosmetic colors and general corrosion resistance. Type III (hardcoat) produces a thick 30–50µm coating at sub-zero temperatures, providing extreme wear resistance.
Does anodizing add dimensions to the part? +
Yes. Type II anodizing typically increases outer dimensions by 5–10µm per surface, while Type III adds 20–25µm. Our CNC engineers compensate for this dimensional growth prior to machining.
Can you mask precision threads and bearing bores from anodize or powder coat? +
Yes. We use custom silicone plugs, caps, and die-cut polyimide tapes to protect tapped holes, critical datums, and grounding pads from coating penetration.
Do your finishes meet environmental regulations? +
All our chemical finishes and coatings are 100% compliant with EU RoHS 3 (Directive 2015/863) and REACH regulations, using hexavalent-free trivalent chromates.
