Types of Finishing & Coatings

Automated Finishing with Collaborative Robots

Premier Aluminum utilizes collaborative robotic finishing systems to ensure consistent results with every component. These automated processes reduce variability, improve surface uniformity, and enhance worker safety while increasing throughput. Robotics-driven finishing provides unmatched accuracy and repeatability across production runs.

Anodizing

Anodizing increases corrosion resistance, surface hardness, and wear resistance while also allowing for decorative finishes. This process is ideal for components exposed to demanding environments where both durability and appearance matter.

Impregnation

Impregnation seals porosity within aluminum castings, improving leak resistance and extending the lifespan of parts. It is especially valuable for pressure-retaining components or parts used in fluid systems.

Chromate

Chromate conversion coatings add a layer of corrosion protection while serving as a base for subsequent paint or powder coating applications. This process enhances adhesion and surface stability.

Blasting

Blasting prepares the aluminum surface by removing contaminants, smoothing rough edges, and creating the proper texture for coatings or secondary finishes.

Polishing

Polishing enhances both function and aesthetics, producing a smooth, reflective finish. It is often applied to parts where surface appearance or reduced friction is required.

Powder Coat

Powder coating delivers a durable, attractive finish with superior corrosion resistance. Available in a wide range of colors and textures, it provides excellent adhesion and environmental durability.

Plating

Plating adds metallic coatings to improve conductivity, corrosion resistance, or surface hardness, depending on application needs.

Non-Stick Coating

Non-stick coatings improve functionality by reducing surface adhesion and friction, making parts easier to clean and more efficient in use.

Passivating

Passivation treatments enhance resistance to oxidation and improve the longevity of aluminum components, ensuring they remain reliable in challenging environments.
