Our Surface Finish Service
Brushing
creating a fine, linear texture on the surface using abrasive tools. It enhances appearance by giving a satin or matte finish.
Sandblasting
using high-pressure abrasive particles to clean, roughen, or matte the surface, improving texture and coating adhesion.
Powder Coating
electrostatically charged powder is sprayed onto a part and cured with heat, forming a durable, colorful, and corrosion-resistant surface.
Matt Painting
a spray coating process that gives parts a smooth, non-glossy finish for a modern, low-reflection appearance,
Glossy Painting
a spray coating that provides a shiny, reflective finish, enhancing visual appeal and surface smoothness.
Clear Polishing
Buffing process that produces a smooth, high-gloss, transparent finish for visual clarity.
Mirrow Polishing
a high-grade polishing process that creates an ultra-smooth, reflective, mirror-like surface
Electropolishing
smoothing and brightening metal surfaces by removing a thin layer, improving corrosion resistance and cleanliness.
Anodizing
forming a durable oxide layer on aluminum, improving corrosion resistance, surface hardness, and allowing for decorative coloring.
Black Oxide
chemical conversion coating that forms a dark, corrosion-resistant layer on steel, enhancing appearance and reducing light reflection
Electroplating
depositing a thin metal layer (like nickel, chrome) onto a part to enhance appearance, corrosion resistance, and surface hardness.
Chemical Plating
depositing a nickel layer evenly on a part, improving wear resistance, corrosion protection, and uniform coating on complex shapes.
Phosphating
forming a phosphate layer on metal surfaces to enhance corrosion resistance, improve paint adhesion, and reduce friction.
Passivation
removing surface contaminants and enhances the natural oxide layer on stainless steel to improve corrosion resistance.
Surface Carburizing
diffusing carbon into the surface of low-carbon steel to increase surface hardness while retaining a tough core.
Nitridation
introducing nitrogen into the surface of steel to form a hard, wear-resistant layer with excellent fatigue and corrosion resistance.
Heat Treatment
improving metal’s hardness, strength, or toughness through controlled heating and cooling.
Electrophoresis
uses electric current to deposit a uniform, corrosion-resistant paint layer onto conductive parts—ideal for complex shapes.
