Surface finishes are more than just cosmetic enhancements—they are engineered solutions that boost performance, durability, and functionality. Our finishes are tailored to your precise needs, offering corrosion resistance, wear protection, thermal conductivity, or a striking aesthetic appearance.

Alumite Sulfate

Alumite sulphate anodising provides a non-conductive, corrosion-resistant coating for aluminium die castings, enhancing protection through a nickel acetate seal.

Black Anodize

Black anodise is a non-conductive protective coating applied to aluminium die castings which is enhanced by boiling in a nickel acetate solution for maximum corrosion resistance. It provides excellent colour retention and durability while allowing for a wide range of dye options.

Black Chromate With Zinc

Black chromate is a thin chemical conversion coating applied over zinc plating that enhances corrosion resistance and provides a black finish without adding significant thickness.

Black Chromate Without Zinc

Black chromate without zinc is a cost-effective coating for zinc die cast parts, offering corrosion resistance and enhanced salt spray resistance. Typically, it's less than 0.000001 inches thick and can be finished with a water-based lacquer.

Black E-Coat

Black e-coat is an electrically applied paint that serves both decorative and protective purposes. Typical thickness ranges from 0.0002 to 0.001 inches.

Black Oxide

Black oxide offers a corrosion-resistant, uniform black finish that protects parts without altering dimensions, enhancing durability and performance while being economical.

Black Powder Coat

Black powder coating offers a durable, high-gloss finish with excellent colour consistency and scratch resistance, while being environmentally friendly and providing anti-corrosion properties.

Browning

Browning surface finish offers a dark, rustic appearance while providing a layer of corrosion resistance. This finish enhances durability and adds an attractive, vintage look, making it suitable for both functional and decorative applications.

Brushed Satin Chrome

Satin chrome is a highly durable surface coating prized for its aesthetic appeal, with a typical thickness of 0.00075 inches.

Chem Film

Chem film, also known as conversion coating, is a protective, conductive coating for aluminium that prevents corrosion and improves paint adhesion without altering dimensions. Two types are available: Class 1A for general corrosion prevention and Class III for low electrical resistance.

Chromate

Chromate is a thin chemical conversion coating applied to die cast surfaces that enhances corrosion resistance. It also improves adhesion while adding minimal thickness.

Clear Chromate

Clear chromate is a thin chemical conversion coating applied over zinc plating that enhances corrosion resistance and provides a slight iridescent blue finish, while contributing no significant thickness.

Copper

Copper surface finish has excellent conductivity and a visually appealing reddish hue. It provides good corrosion resistance and is often used as a base layer for additional coatings or plating.

Copper-Nickel-Tin

Copper-nickel-tin plating provides solderability to the base metal, with bright tin offering superior appearance while matte tin is favoured for better soldering performance.

Cobalt-Tin

Cobalt-tin plating, applied over bright nickel, mimics the appearance of chrome with a hard, durable finish, offering a convincing chrome-like look and enhanced durability.

Electroless Plating

Electroless nickel, the most common type of electroless plating, provides excellent corrosion resistance, wear resistance, and a range of other properties through its low, medium, and high phosphorus variants.

Gray/Silver Powder Coating

Gray or silver powder coating delivers a sleek, durable finish with excellent corrosion and scratch resistance, enhancing both appearance and longevity of die-cast components.

Gold

Gold maintains conductivity and solderability without oxidation, making it ideal for electronics. Its excellent durability and hardness, especially when alloyed with cobalt, justify its use.

Hard Chrome

Hard chrome surface finish provides hardness and durability, enhancing resistance to wear and corrosion. This finish also improves overall performance and extends its life by offering a tough, protective layer.

Impregnation

Impregnation seals porosity and creates watertight components. It is a great option to use after machining to create a leak-free component.

Nickel

Nickel plating, a yellowish-white, hard, reflective finish, enhances wear resistance, solderability, and dimensional restoration. It is often used as an underlayer for chromium or as a semi-bright option for applications requiring greater ductility.

Olive Drab

Olive drab chromate provides a dark green finish with excellent corrosion resistance and adds minimal thickness of less than 0.000001 inches.

Organic Coatings

Organic coatings provide a versatile finish that offers protection against corrosion, abrasion, and UV degradation. These coatings, which can be applied in various colours and textures, enhance appearance while adding a layer of durability.

Passivating

Passivating surface finish is a conversion coating that forms a protective oxide layer, improving corrosion resistance and increasing durability. This treatment stabilises the surface, reducing the risk of rust and extending the part's lifespan.

Phosphating

Phosphating surface finish provides die cast parts with improved corrosion resistance and better adhesion for subsequent coatings. This treatment creates a protective layer that enhances paint and oil adherence while offering moderate wear resistance.

Polished Chrome

Polished chrome is a bright, mirror-like finish that offers corrosion protection, durability, and aesthetic appeal. It has a typical thickness of 0.0015 inches.

Polyurethane Paint

Polyurethane coatings are durable and ideal for exterior use, available in smooth or textured finishes. They typically air dry but can be baked to accelerate curing, with a typical thickness of 0.001 inches.

Silver

Silver provides excellent electrical and thermal conductivity, along with high ductility and malleability, making it ideal for die cast parts used in electronics. It has a typical plating thickness is 0.0002 inches.

Spray Painting

Spray painting offers die cast components a customisable, protective finish that enhances appearance and durability while improving resistance to wear and corrosion.

Teflon

Teflon is a thermally cured solid film lubricant that enhances torque and tension control while offering corrosion, chemical, and abrasion resistance. It is typically applied in thicknesses ranging from 0.0003 to 0.001 inches.

Tin

Tin, a ductile and solderable metal, enhances die-cast components with excellent coverage and a decorative finish, though its solderability can be improved by using an undercoat of copper or nickel.

Trivalent Chromate

Trivalent chromate is a thin, chemical conversion coating that enhances corrosion resistance and provides a clear or slightly tinted finish. It is environmentally friendly and offers improved performance compared to traditional hexavalent chromate.

Trivalent Clear Chromate

Trivalent clear chromate provides a thin, transparent finish that enhances corrosion resistance and maintains an attractive appearance while being more environmentally friendly.

White Bronze

White bronze surface finish provides a durable, corrosion-resistant layer that offers a bright appearance. It enhances the component's longevity and wear resistance while maintaining a smooth, polished look.

Yellow Chromate With Zinc

Yellow chromate, a thin chemical conversion coating applied over zinc plating, enhances corrosion resistance and provides a paint base while adding no significant thickness parts.

Yellow Chromate Without Zinc

Yellow chromate without zinc provides die cast components with a dull, olive-drab finish through a chemical conversion coating that significantly enhances corrosion resistance, with special seals extending protection beyond 500 hours.

Zinc Plating With Trivalent Black Passivation

This finish offers die cast components' superior corrosion resistance and a sleek black finish while being environmentally friendly.

Zinc Plating With Trivalent Yellow Passivation

This finish offers die cast components superior corrosion resistance and a vibrant yellow finish while being environmentally friendly.
