We provide sheet metal cutting and forming services for the fabrication of sheet metal parts. The automated cutting and forming processes guarantee high precision and quality of ready parts. All parts can be subject to post-processing upon your request: coatings, heat-treatment and others.

Finishing Options for Sheet Metal Fabrication

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.

Anodising (type II)

Type II anodise 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 colour
• Type II coatings are susceptible to wear and may bleach or fade under prolonged direct sunlight
• Possibility of requesting custom colours (RAL)

Hardcoat anodising (type III)

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

Notes:

Colours tend to come out slightly dark due to the thickness.

Powder coating

Provides a continuous, protective colour 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

Media tumbling

Tumbling vibrating media to remove sharp edges and burrs on machined parts.

Notes:

Sharp edges may be dulled. Parts with fragile features are not recommended for tumbling.

Final result:

• Smooth in the touch
• Satin-like matte appearance

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

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
• Type II chromate coating will appear clear and does not affect surface colouration

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.

Notes:

The zinc coating creates a physical barrier that prevents rust from reaching the underlying metal surface.

Final result:

• Increased corrosion resistance

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

Silver plating

Electroplating silver provides good corrosion resistance but easily tarnishes. Silver offers high solderability and electrical conductivity.

Final result:

• Silver-like appearance
• Increased corrosion-resistance
• Easily tarnishes
