Key Technology - Advanced Investment CastingThe competence in rapid technology and casting techniques qualifies PORTEC to handle with two investment casting processes. The differential pressure casting with high accuracy while reduced lead timecalled as flask investment casting, and the more modifiable conventional investment casting. PORTEC GmbH is worldwide the first rapid prototyping service provider, who applies the Rapid-Shell-Casting technology (RSC) combined with a new drying tunnel process. So PORTECs technology combines the rapidity off differential pressure casting with the advantages of conventional investment casting:
- wide variety of alloys and
- improved cast structures.
