The mold is made from permanent steel pattern which is reusable and the metal is poured into the mold under high pressure to increase the mechanical properties of the aluminum and to eliminate internal porosity.
Advantages
- Reusable permanent mold
- Mold filling is under controlled pressure
- High mechanical properties
- Dimensional control equal to die-casting with higher strength alloys
- Small dendrite arm spacing (DAS)
- Non-turbulent mold filling
- High quality
