Complete your CNC machined parts with professional surface treatments. We offer a comprehensive range of finishing options to enhance appearance, durability, and functionality.
Get QuoteUnlike most CNC shops that outsource surface finishing, we operate our own dedicated anodizing facility established in 2012. This gives us complete control over quality, lead time, and cost for your anodizing requirements.
Deposit metal coatings through electrochemical process for enhanced properties
Electrochemical process that deposits a protective zinc layer on steel and iron parts, providing excellent corrosion resistance through sacrificial protection.
Creates a hard, lustrous coating that provides excellent wear resistance and decorative appeal. Available in bright, satin, and electroless variants.
Deposits a hard chromium layer providing superior hardness, excellent wear resistance, and a brilliant decorative finish with low friction coefficient.
Deposits a copper layer that provides excellent electrical conductivity, often used as a base layer for subsequent plating or for its conductive properties.
Surface modification through chemical reactions for protection and enhanced properties
Chemical conversion process that produces a black magnetite (Fe3O4) layer on steel and iron parts, providing rust prevention and aesthetic appeal.
Creates a crystalline phosphate conversion coating that enhances paint adhesion, provides moderate corrosion protection, and improves lubricity.
Chemical treatment for stainless steel that removes free iron and enhances the natural chromium oxide layer, maximizing corrosion resistance.
Autocatalytic chemical process that deposits uniform nickel-phosphorus alloy without external electrical current, ideal for complex geometries.
Electrochemical process primarily for aluminum that creates a durable oxide layer
Standard sulfuric acid anodizing that creates a porous oxide layer suitable for dyeing. Provides good corrosion resistance and aesthetic appeal.
Hard anodizing process that produces a much thicker, harder, and more wear-resistant oxide layer for demanding applications.
Apply protective and decorative coatings for enhanced appearance and protection
Liquid paint application using spray guns to atomize and deposit paint onto workpiece surfaces. Offers unlimited color options and various finish effects from high gloss to matte.
Paint Types:Dry finishing process where electrostatically charged powder is applied to grounded workpieces, then heat-cured to form a durable, high-quality finish. More environmentally friendly than liquid paint with no solvent emissions.
Available Textures:Immersion coating process where workpieces are submerged in paint bath and electric current deposits paint uniformly on all surfaces. Provides excellent coverage on complex geometries and recessed areas that spray methods cannot reach.
Thermochemical processes to increase surface hardness while maintaining core toughness
Diffuses carbon into the surface of low-carbon steel at high temperature, creating a hard, wear-resistant case while maintaining a tough, ductile core.
Diffuses nitrogen into the surface at lower temperatures than carburizing, creating extremely hard surface layer with excellent wear and fatigue resistance.
Rapid localized heat treatment using high-frequency electromagnetic induction, followed by quenching to harden specific surface areas while minimizing distortion.
Physical surface modification for texture, appearance, and finish enhancement
Progressive abrasive process to achieve mirror-like surface finishes with extremely low roughness values. Includes mechanical, chemical, and electropolishing methods.
High-pressure abrasive media treatment to create uniform matte textures, remove burrs, clean surfaces, and prepare for subsequent finishing processes.
Creates directional linear texture (hairline pattern) on metal surfaces using abrasive belts or brushes, providing distinctive metallic appearance.
Advanced thin-film coating technologies for superior hardness and decorative effects
Vacuum process where metal is evaporated or sputtered and deposited as a thin film onto the workpiece surface. Produces extremely thin, hard coatings with excellent wear resistance and rich decorative colors.
Common PVD Methods:Similar to PVD but forms coating through chemical reactions of gaseous precursors on the heated workpiece surface. Produces coatings with superior adhesion strength, though requires higher process temperatures.
Add logos, text, codes, and decorative patterns to finished parts
Uses focused laser beam to ablate material surface, creating permanent high-precision marks. Non-contact process ideal for delicate parts and high-volume production.
Transfers ink through a fine mesh screen onto the workpiece surface. Cost-effective for large batches with vibrant colors and good ink coverage.
Indirect offset printing using silicone pad to transfer ink from etched plate to irregular or curved surfaces not suitable for screen printing.
Additional specialized surface treatments for specific applications
Chrome-free, environmentally friendly anti-corrosion coating using zinc and aluminum flakes in an inorganic binder. Provides excellent corrosion protection without hexavalent chromium.
Fluoropolymer coating providing extremely low friction coefficient, chemical resistance, and non-stick properties for demanding applications.
Chemical treatment for aluminum that provides corrosion protection and improves paint adhesion. Available in clear (RoHS) and yellow/iridescent versions.
