Mechanical Finishes
Surface preparation and texturing — often combined with chemical coatings.
Bead Blasting
Uniform matte finish. Removes tool marks. Ra 1.6–6.3 μm.
Tumbling
Deburrs edges, smooths surfaces. Ideal for high-volume small parts. Ra 0.4–1.6 μm.
Brushing
Linear grain pattern. Industrial-modern look on SS and aluminum. Ra 0.3–1.2 μm.
Polishing / Mirror
Progressive buffing to #4 satin or #8 mirror. Ra 0.05–0.2 μm.
Sandblasting
Aggressive texturing. Excellent coating adhesion. Ra 3.2–12.5 μm.
Lapping / Honing
Precision flatness for sealing faces and optical components. Ra 0.01–0.1 μm.
Coating Quality You Can Verify
Every finished part ships with documentation.
Thickness Testing
ASTM B499/B487 calibrated gauges. Every batch tested.
Salt Spray Testing
ASTM B117. 24h to 1000+ hours per your spec.
