Metal Fabrication Techniques

Sustainability & Metals

  • Extremely Sustainable
  • Infinitely recyclable without losing any of their properties

Manufacturing with Metals

  • Vehicles
  • Bicycles
  • Lamps
  • Street Furniture
  • Tools
  • Laptops
  • White Goods

Manufacturing Methods

  • Extrusion
  • Panel Beating
  • Pressing
  • Spinning
  • Rolling
  • Forging
  • Cutting/Joining
  • Casting

Panel Beating

  1. Dishing using a sandbag
  2. Curving using an English Wheel
  3. Chasing Shapes on a former

Advantages of Panel Beating

  • Fast set up time
  • Very low tooling costs
  • Suitable for single or small batch production
  • complex non-symmetrical 3d forms possible


  • Old fashioned
  • Very slow
  • Requires very skilled workforce
  • Not suitable for mass production

Sheet Metal Pressing

Flywheel Press

Hydraulic Press

Can be used for:

  1. Punching
  2. Blanking
  3. Slitting
  4. Forming
  5. Deep Drawing


Blanking – Keep the part you punch out

Metal Slitting (Piercing)

  • CNC Turret Punch Press – patterns

CNC Turret Punch Press

  • Much faster than traditional punch press
  • Automatic sheet handling
  • Largest turrets can contain up to 50 different punch and die sets
  • Programmable for complex hole patterns
  • Low tooling

Press Forming

  • Used to create complete component parts

Press Forming: Deep Drawing (for example for saucepans)


  • Very high accuracy and precision
  • Very High production rates possible
  • Does not require a highly skilled workforce
  • Suitable for high volume mass production
  • Complex non-symmetrical forms possible


  • Expensive initial set up
  • Very high complex tooling cost
  • Not suitable for one off or customised production.

Another simple but effective lecture. I definitely find that this is benefiting my work and specifically my design thinking.
