What is sheet metal fabrication?

  • Flat sheets of steel or aluminium turned into metal structures
  • Sheet metal can be cut, bent, fold or punched into nearly any shape
  • Generally done by cutting and burning the metal
  • Parts are assembled thru fasteners or welding to create a useful assy
  • Finishing is done by sand blasting, primer and painting etc

Laser Cutting

  • A beam of laser to cut through different kinds of metals
  • High power laser ultimately burns, vaporize & melt the sheet metal
  • Laser beam movement is controlled thru CNC program
  • Consistent quality
  • Fast and effective
  • Cut parts more accurately than other technologies
  • High costs
  • Lead time: 5 to 10 days

Metal Bending

  • One of the most common sheet metal fabrication operations
  • Press braking, flanging, die bending, folding and edging
  • Bending is done through the application of force on a workpiece
  • The force must exceed the material’s yield strength
  • Uses dies to produce a U, V or channel shape in ductile materials
  • Effective for mass production
  • Reduced set up time
  • Max. Part Size: 300x300x300 mm
  • Lead time: 5 to 10 days

Surface Finish

Surface Finish Image Remark
As machined (Ra 3.2 µm)
  • Quickest turnaround
  • Parts are left with visible tool marks
  • Potential sharp edges and burrs
Brushed (Ra1.2µm)
  • The part is to be supplied with a rough polish which will remove most machining marks
  • Some scratches and machining marks still may remain
  • Not advisable for applications where corrosion resistance is required
Powder coated
  • Powder coating is a type of coating that is applied as a free-flowing, dry powder
  • Creates a hard finish that is tougher than conventional paint
  • Can produce thicker coatings than conventional liquid coatings
  • Powder coat finishes are available in a large range of colours
Satin finish (Beed blast)
  • Fine glass beads blasted at a high pressure without damaging the surface
  • Creates a uniform surface finish on machined parts
  • It gives a matte finish with light texture
Black Oxide
  • Black oxide imparts a deep, black, lustrous appearance
  • Replicates the surface finish of the part
  • Provides mild corrosion protection
  • Primarily used because of its aesthetic properties
  • No significant dimensional changes to a black oxide part
  • The layer thickness depth approximately one micron
