1
Q
True Centrifugal
A
Symmetrical shape i.e. pipes
2
Q
Semi Centrifugal
A
Symmetrical shape i.e. wheels with spikes
3
Q
Centrifuge Centrifugal
A
Rotating mold (Centrifugal force), used to improve density towards the exterior of the Casting.
- Symmetrical
- Used in a cluster
4
Q
Permanent
A
Made of metal with machined cavities, metal is gravity poured into the mold, and has a Gating system built in.
- Small Casting only
- Simple shapes
- Expensive
5
Q
Hot Chamber Die Casting
A
Molten metal injected under pressure, vents allow air to escape as the metal fills with the Die.
- 45PSI
- For Aluminium Alloys
6
Q
Cold Chamber Die Casting
A
Molten metal injected under pressure, vents allow air to escape as the metal fills with the Die.
- Up to 14 500PSI
- For aluminium, copper or magnesium Alloys
7
Q
Continuous Casting
A
Process where metal is poured into a casting machine that uses rollers to produce either a Billet, Bloom or Slab casting.
