Our Wide Range of Surface Finishing Options
Explore a range of surface finishing options to enhance durability, appearance, and functionality. We offer coatings, anodizing, polishing, and more, tailored to meet your specific performance and aesthetic needs.
As Machined
Standard finish with 3.2 μm (126 μin) surface roughness; deburred and free of sharp edges.
Anodizing
Anodizing forms a protective oxide layer that adds strength, hardness, corrosion resistance, and optional color to metal parts.
Black Oxide
Black oxide is a chemical coating for ferrous metals that adds corrosion resistance with a black finish and no change in dimensions.
Colored Anodizing
Provides corrosion resistance and visual appeal in various colors, commonly used on aluminum parts.
Color Dyeing
Imparts vibrant, long-lasting colors to plastic through a dyeing process, ensuring a consistent appearance without altering material properties.
Electroplating
Electroplating adds a thin metal layer to a part through an electrolytic process, enhancing its appearance and performance.
Fumigation Transparent Coating
A clear protective layer that boosts durability and enhances surface clarity.
Gold Plating
Improves conductivity, corrosion resistance, and appearance, often used in electronics and high-end products.
Heat Treatment
Heat treatment heats metal to a controlled temperature to enhance its strength, hardness, and wear resistance for tough environments.
Laser Etching
Laser etching uses a focused laser beam to create permanent raised marks on metal or plastic surfaces.
Nickel Plating
Enhances wear resistance, hardness, and corrosion protection, commonly used in mechanical and electronic components.
Pad Printing
Transfers ink from an engraved plate to plastic surfaces, perfect for intricate logos and multi-color designs.
Polishing
Polishing uses abrasives to produce a smooth, mirror-like finish on metals such as steel and aluminum.
Plating
Plating applies a layer of metal—such as zinc, chrome, or copper—to improve corrosion resistance and offer a range of color finishes.
Painting
Our industrial painting services utilize advanced coatings and a refined process to enhance both functionality and appearance.
Passivation
Passivation cleans stainless steel and forms a protective oxide layer, improving corrosion resistance and durability in harsh environments.
Powder Coating
Powder coating provides a durable, wear-resistant finish, perfect for outdoor equipment and machinery. It offers excellent protection and comes in a variety of colors.
Plasma Nitriding
Improves hardness and fatigue strength by infusing nitrogen into the surface, perfect for high-performance applications.
QPQ (Quench-Polish-Quench)
A surface hardening process that enhances wear and corrosion resistance, ideal for precision components.
Silver Plating
Offers excellent conductivity and antibacterial properties, making it perfect for electrical and medical applications.
Spray Coating
Applies a protective or decorative coating to plastic surfaces, improving appearance, durability, and resistance to wear and chemicals.
Silk Screening
Utilizes high-pressure abrasive particles to achieve a matte or textured finish on plastic surfaces, enhancing grip and appearance.
Sandblasting
Utilizes high-pressure abrasive particles to achieve a matte or textured finish on plastic surfaces, enhancing grip and appearance.
Tin Plating
Prevents oxidation, improves solderability, and is frequently used on electronic connectors.
Water Transfer Printing
Uses a water-based printed film to transfer detailed designs onto plastic parts, creating a smooth, decorative finish.
Water Plating
A surface treatment that uses electrolysis to apply a thin metal layer on plastic parts, enhancing conductivity, corrosion resistance, and appearance.
Zinc Plating
Safeguards steel from corrosion with a thin zinc coating, commonly used in automotive and construction applications.
Zinc-Nickel Alloy Plating
Provides exceptional corrosion resistance and durability, commonly used in the automotive and aerospace industries.
