Original manufacturer document covering the corresponding product specifications, configuration or applicable loading conditions.
View resource →Product overview
PA 500 is a semi-automated melt spinner for metal ribbons under high vacuum or an inert atmosphere, with 100–500 g per run depending on alloy and melting temperature.
Key features
- Temperature up to 1500 °C and generator power 30 kW; water-cooled copper wheel dimensions Ø250 × 60 mm.
- Water-cooled crucible holder with boron-nitride or quartz crucible; positioning controls nozzle-to-wheel distance and supports semi-automatic melt ejection.
- Touch-screen operation, software pressure control, integrated temperature control and automated evacuation/flushing.
- Pressure parameters are individually programmable; the movable rack integrates a turbomolecular or roughing pump and high-vacuum gauge.
- Complete system includes generator, ribbon collection vessel, valves and safety features.
