Aluminium Cast Tooling Plate Machining

A Guide to aluminium cast tooling plate CNC Machined Parts: Properties, Applications and Design Considerations

What is Aluminium Cast Tooling Plate?

As the name implies aluminium cast tooling plate is manufactured using a casting process, giving the material a fine granular structure. The plate’s two main faces have a machined finish to Ra 0.4 - 0.8 ųm, typically protected with thin polycoat film.

Cast tooling plate is most commonly available in the UK in subtly different 5000 series aluminium grades. However cast tooling plate is also available in both 6000 and 7000 series aluminium, although this is not readily available in the UK.

Conventional aluminium plate is manufactured from forged wrought ingots rolled to size and heat treated. Cast aluminium tooling plate is manufactured close to finish thickness by a horizontal continuous aluminium flow casting process delivering a uniform fine grain structure. The cast plate is then heat treated above 370°C for close to 10 hours to fully anneal (stress relieve) to remove any manufacturing stresses. The cast plate is then lightly machined to its finished size and protective films applied.

Main Attributes of Cast Aluminium Tooling Plate:

  • Uniform fine grain structure
  • Very low porosity
  • Good tensile strength
  • Good ductility
  • Stress free condition similar to condition “0” temper wrought plate
  • Ra 0.4 - 0.8 ųm finish to main faces, typically protected with thin polycoat film
  • Very good flatness, typically 0.15 - 0.5 mm dependant on area of plate
  • Very good machinability
  • Excellent dimensional stability even when heavily machined
  • Excellent base material to start machining manufacture
  • Excellent mechanical and dimensional stability when repeatedly heated and cooled in its application of use
  • Annealing after machining is not required 
  • Good polishing characteristics
  • Good anodising and hard anodising properties
  • Excellent corrosion resistance
  • Very good weldability

Cast Tooling Plate Components, Applications & Industries

Cast tooling plate is extensively used for machine building, tooling and fixturing applications for the following reasons:

1. It provides a good value, machined finish, flat base material from which to commence manufacture for the majority of low to medium duty applications

2. It is dimensionally stable even when large amounts of material have been removed

3. It is thermally and dimensionally stable in operation applications that involve cyclical heating and cooling
