The machine supports casting in gold, silver and platinum and uses an induction casting process with controlled atmosphere. Its automatic operation, 7-inch touchscreen and compact footprint make it suitable for small workshops, design studios, laboratories and limited-batch jewellery production units.
Prometheus is built to improve casting consistency, reduce porosity and support smoother surface results. Its vacuum and argon overpressure system helps improve metal flow and flask filling, while temperature control up to 2,000°C allows the machine to handle high-value precious metals under controlled conditions.
A key benefit for workshops is its simplified infrastructure requirement. The machine does not require compressed air and comes with an integrated air/water cooling system, with an external chiller available as an optional accessory.
With a maximum casting capacity of 140 g for 18kt gold, 90 g for silver and 150 g for platinum, the machine is suited for small to medium jewellery casting requirements. Its maximum flask size of 90 mm height and 100 mm diameter further supports practical jewellery production applications.
For manufacturers focused on custom pieces, repairs, prototypes and small-batch production, Orotig Prometheus offers an automated casting option that can help improve turnaround time, reduce dependency on external casting services and bring better control to in-house production.
