We offer a variety of surface finishing options for precision CNC machined parts, including anodizing, sandblasting, polishing, powder coating, and plating to meet both functional and aesthetic requirements.
Achieves a superior mirror-like aesthetic while significantly reducing surface friction and bacterial adhesion. It eliminates microscopic abrasions, making it the ideal choice for medical devices and high-end decorative hardware where cleanliness and “shelf-appeal” are critical.
Delivers a consistent, non-reflective matte finish that effectively masks machining tool marks and surface imperfections. This process creates an ideal surface profile (roughness) that dramatically improves the adhesion strength of subsequent coatings or paints.
Creates a distinct linear grain that enhances the premium feel of metal parts. Beyond its decorative value, the brushed texture is highly functional for masking fingerprints and minor scratches, ensuring components maintain a pristine look even in high-touch applications.
Transforms the aluminum surface into an exceptionally hard, ceramic-like layer. It provides superior wear resistance for moving parts and excellent electrical insulation, while offering robust protection against harsh environmental corrosion without compromising part integrity.
A critical chemical treatment for stainless steel that removes free iron from the surface, preventing rust and oxidation. Since it does not add any thickness, it is the go-to solution for high-precision components that require maximum corrosion resistance while maintaining strict dimensional tolerances.
Provides a durable, non-reflective black finish with zero dimensional change, ensuring that tight-tolerance threads and assemblies fit perfectly. It offers cost-effective corrosion resistance and is widely used for optical equipment to eliminate light glare and reflections.
