Surface Treatment

Precision Surface Finishing Services for Metal Castings

From industrial shot blasting to advanced electroplating and specialized protective coatings, Vast provides a comprehensive suite of surface finishing solutions. Our processes are engineered to significantly enhance the corrosion resistance, surface hardness, and aesthetic appeal of your investment cast parts, ensuring they perform reliably in demanding environments.

Comprehensive Surface Treatment Portfolio

We offer a diverse range of finishing options tailored to your material and application needs:

Mechanical Finishing:
- Shot Blasting & Sandblasting: Removes oxidation and creates a uniform matte texture, ideal for pre-coating preparation.
- Shot Peening: Enhances fatigue life by introducing compressive residual stress to the part’s surface.
- Vibratory Polishing & Mirror Polishing: Achieves smooth, high-luster surfaces for decorative or sanitary applications.
Chemical & Protective Coatings:
- Electroplating (Zinc, Nickel, Chrome): Provides superior wear resistance and a professional metallic finish.
- Passivation & Electropolishing: Critical for stainless steel castings to maximize chemical stability and corrosion resistance (especially for medical and food-grade parts).
- Anodizing: Offers durable, corrosion-resistant, and color-customizable finishes for aluminum components.
High-Performance Barriers:
- Powder Coating: Delivers a thick, impact-resistant protective layer in a variety of RAL colors.
- Black Oxide: A precision coating that provides mild corrosion resistance without altering the part’s dimensional tolerances.

Why Integrate Finishing with Vast?

Consolidating your casting and finishing with a single-source partner like Vast offers strategic advantages:

Strict Quality Assurance: We conduct rigorous inspections, including adhesion tests and salt spray testing, to verify coating integrity.
Shorter Lead Times: Eliminate the logistics and delays of shipping parts between multiple vendors.
Cost Efficiency: Reduce the total cost of production through streamlined project management and minimized material handling.

Aluminium Alloy Surface Blasting

Surface blasting on aluminum alloys provides a uniform texture, improves bonding for coatings, and enhances resistance to wear.

Black Coating Spigots – Surface Coating

Protective surface coatings deliver a durable black finish, enhancing both the aesthetics and functional lifespan of spigots.

Flounder Gigs – Electrolytic Polishing

Electropolishing smooths and brightens metal surfaces, improving corrosion resistance and enhancing long-term performance in harsh environments.

Glass Spigot – Anodising

Anodising creates a protective oxide film on aluminum spigots, improving corrosion resistance and offering decorative finishes.

Glass Clamps – Wire Drawing (Brushed Finish)

Brushed wire drawing produces a satin finish on glass clamps, reducing glare and providing a refined, modern look.

Glass Standoff – Mirror Polishing

High-gloss mirror polishing enhances the visual appeal of glass standoffs while maintaining precise dimensional accuracy.

High Carbon Steel – Blackening

Chemical black oxide treatment forms a protective layer that resists rust while giving components a sleek, uniform dark finish.

Laser Marking – Stainless Steel Bottle Opener

Permanent laser marking provides high-definition logos or text on stainless steel surfaces without compromising durability.

Oval Cowl Vents – Mirror Polishing

Mirror polishing achieves a bright, reflective finish that enhances appearance and improves resistance to surface contamination.

Stainless Steel Surface Blasting

High-pressure blasting creates a clean, uniform surface on stainless steel, improving adhesion and enhancing corrosion resistance.

Water Tap Faucet Finishing

Precision surface finishing ensures faucets achieve both functional durability and a polished, attractive appearance for long-term use.

Dacromet & Geomet Coating

Advanced anti-corrosion coating applied by spraying and baking, delivering superior durability and heat resistance compared to traditional plating.
