Finishing Types

Finishing metal is a demanding task that can make a crucial difference in the appearance and durability of the final product. For the best results, we recommend that you rely on our finishing services. We offer many types:

    Anodizing is an electrolytic process used to increase the thickness of the oxidation that naturally forms on the surface of many metals. Typically used with aluminum, anodizing takes advantage of the inherent properties of aluminum oxide to create a hard, corrosion-resistant surface. Anodized aluminum has an attractive metallic sheen, and can be either clear or dyed in various colors.
     
    Clear coat (anodizing)  Clear anodizing is a process that creates a thin layer of aluminum oxide coating on aluminum metal without the use of dyes or pigments.
     
    E-coating is an electropainting or electrophoretic lacquering process to deposit a paint or lacquer coating.
     
    Electrogalv: The most common galvanizing method is electrochemical deposition of the zinc alloy. Because this process creates a relatively thin layer of galvanization, painting is generally recommended for outdoor applications to provide the best corrosion resistance.
     
    Hot-dip galvanization: The part is passed through a molten zinc bath, providing a much thicker coating of zinc at a somewhat higher cost compared to electrogalv. Hot-dip galvanization produces a characteristic crystallization pattern or “spangle” on the surface.
     
    Paintgrip: Galvanized steel that is dipped in a phosphate bath for additional corrosion protection and to improve paint adhesion.
     
    Paintlock: Galvanized steel that has a zinc coating which is electronically deposited and then chemically treated to improve adhesion of paint or powdercoat finishes.
     
    Plating refers to a number of processes for depositing a coat of one type of metal on the surface of another. Plating materials can be chosen for their beauty, corrosion resistance, hardness and a variety of other purposes. Examples include gold, silver, chrome, zinc, tin, cadmium and many others. Plating techniques also vary, and include both electroplating and electroless methods. Contact us to discuss the right plating material and method for your project.
     
    Powder coating is an electrostatic process for applying a dry, powdered material such as polyester, polyurethane or epoxy. The piece is then heat-cured to flow the material together and create the final finish. Powder coating is generally thicker and more durable than paint, although the cost can be somewhat higher depending on the project. A broad selection of colors is available.

Large sheets and coils, corrugated pieces, finished components and even special designs – Accurate Perforating can apply virtually any finish to perforated part, as long as we determine that the finish is appropriate for the material. Contact us to discuss your finishing ideas and questions.

     
    Silk screening is a process which is used to create prints on a wide variety of materials via transferring an ink or die through a pattern on a very fine mesh stretched tightly onto a frame.
     
    Kynar®, or polyvinylidene fluoride (PVDF), is a fluoropolymer plastic that provides excellent strength and resistance to acids, bases and solvents. Available in a wide range of colors, textures and gloss, the durability and heat resistance of Kynar make it an excellent choice for architectural projects, especially where perforated metal is used to control heat gain. Kynar is also a perfect choice for industrial applications where corrosive substances are used. Specifically formulated to be applied to aluminum.
     
    Duranar is a fluoropolymer system with multiple coats that provides excellent protection against chipping, peeling, fading and staining in weather-exposed applications.  Specifically formulated to be applied to aluminum.
     
    Tnemec is a high-endurance coating or finish specially formulated to be applied to aluminum and carbon steel. Used in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat.
     
    PVDF is a specialty plastic coating or finish in the fluoropolymer family generally used in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat; also called PVDF. Specifically formulated to be applied to aluminum.
     
    Hylar is aspecialty plastic coating or finish in the fluoropolymer family generally used in applications requiring the highest purity, strength, and resistance to solvents, acids, bases and heat; also called PVDF. Specifically formulated to be applied to aluminum.
     
    UV Coating is a curable coating applied directly to metal coatings to enhance the durability, scratch resistance and fade resistance.
