    Annealing

    The annealing process involves the heating of a metal to or near the temperature at which recrystallisation begins without change in the stresses. After heating, the metal is cooled to room temperature in the oven or put in the sand.

    Final result:

    • Improved cold working capacity of the metal
  • CNC machined part without surface finishes (3D render, aluminium)
    Bead blasting (3D render)
    dragger

    Bead blasting

    Bead blasting involves spraying a pressurised stream of tiny beads of media, plastic or glass beads, from a nozzle onto the surface of the part. This removes the burrs and imperfections, leaving a smooth finish.

    Notes:

    The recommended part size is 6-600 mm in both height and width. Smaller parts are hard to hold and tough to produce an even surface.

    Final result:

    • Uniform, matte or satin-like appearance
    • Slightly grainy in the touch
  • Electroless nickel plating (3D render)

    Electroless nickel plating

    Electroless nickel plating provides a uniform nickel coating, which offers protection from corrosion, oxidation, and wear on irregular surfaces.

    Final result:

    • Protection from corrosion, oxidation and wear on irregular surfaces
    • Brighter appearance
  • Electropolishing (3D render)

    Electropolishing

    An electrochemical process that cleans steel parts to reduce corrosion and improve appearance by making the metal brighter.

    Final result:

    • Reduced corrosion
    • Brighter appearance
  • Gold plating (3D render)

    Gold plating

    Gold plating provides good corrosion and tarnish resistance. Gold has low contact resistance, excellent conductivity, and solderability.

    Final result:

    • Gold-like appearance
    • Increased corrosion and tarnish resistance
  • Passivation (3D render)

    Passivation

    A colorless coating that improves corrosion resistance for 200 and 300 series and precipitation hardened corrosion-resistant steels by removing free iron from the surface.

  • Powder Coating Black (3D Render)

    Powder coating

    Provides a continuous, protective color finish on parts using evenly applied, heat-cured paint. The finish is usually tougher and even compared to conventional painting.

    Notes:

    Metals like aluminium and steel can be efficiently coated with polymer powders.

    Available colors:

    • Any custom RAL color

  • Tempering

    A heat treatment method that is mainly dedicated to reducing the amount of hardness of metals. It involves heating the metal to a temperature below the critical point. The temperature is adjusted depending on the amount of hardness that needs to be reduced and it varies depending on the metal type as well.

    Final result:

    • Reduced hardness
    • Increased elasticity and plasticity
    • Reduced yield and tensile strength
  • Custom finish icon

    Custom Finishing

    If you select a custom finish in the Instant Quoting Engine it will require manual review. Manual quoting usually takes 1-2 business days.

    Notes:

    Submitting for manual review with a custom request does not guarantee a quote.

  • Blackening / Black oxide (3D render)

    Black oxide

    Black oxide is a type of conversion coating for ferrous materials, such as steel and stainless steel, which blackens the top layer of the material. It can be used to reduce reflection and glare, as well as provide some additional corrosion resistance without affecting part dimensions.

  • Zinc plating (3D render)

    Zinc coating / Galvanising

    Zinc plating involves the electrodeposition of a thin coating of zinc metal onto the surface of another metal object, known as a substrate. The zinc coating creates a physical barrier that prevents rust from reaching the underlying metal surface.

    Final result:

    • Increased corrosion resistance
