Finishing Options

• 

  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.

  Final result:

  • Slightly grainy in the touch
  • Uniform, matte or satin-like appearance
• Clear anodising type II (3D render, aluminium shown)

  Green anodising type II (3D render, aluminium shown)

  Gold anodising type II (3D render, aluminium shown)

  Orange anodising type II (3D render, aluminium shown)

  Blue anodising type II (3D render, aluminium shown)

  Anodizing (type II)

  Type II anodize provides increased corrosion resistance and can be used as a base for paint and other finishes.

  Notes:

  • Involves using dyes to affect the part’s surface color
  • Anodized colors cannot be matched to specific Pantone or RAL colors
  • Type II coatings are susceptible to wear and may bleach or fade under prolonged direct sunlight

  Available colors:

  • Blue
  • Gold
  • Green
  • Natural
  • Orange
• Black hardcoat anodising type III (3D render, aluminium shown)

  Grey hardcoat anodising type III (3D render, aluminium shown)

  Clear hardcoat anodising type III (3D render, aluminium shown)

  Hardcoat anodizing (type III)

  Type III hardcoat anodize produces a thicker layer of standard anodizing, making it more durable and wear-resistant. Can be used as a base for paint and other finishes.

  Notes:

  • Colors tend to come out slightly dark due to thickness
  • Anodized colors cannot be matched to specific Pantone or RAL colors

  Available colors:

  • Black
  • Grey
  • Natural
• 

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

  Available colors:

  • Black
• 

  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
• 

  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.

• 

  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
• 

  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
• 

  Chromate conversion

  Chromate conversion coatings, also known as chem-film, enhance corrosion resistance and conductivity properties and can be used as a base for paint.

  Notes:

  Type I chromate conversion caused the coating to appear gold or brown in color typically

  Available colors:

  • Gold
• 

  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
• 

  Case-hardening (Carburising)

  A heat treatment process which includes hardening the surface of metal while allowing the metal underneath to remain soft. As the name implies, carburising is inducting carbon or nitrogen into low-carbon alloys at elevated temperatures so that the hardenability increases.

• 

  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

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

  Notes:

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