Edmund Bühler Arc Melter AM A500
Original manufacturer document covering the corresponding product specifications, configuration or applicable loading conditions.
View resource →Product overview
AM A500 combines arc melting, automated evacuation/flushing and casting operations under PLC control. Melting/alloying charge is 100–500 g, while casting charge is maximum 300 g; the capacities are distinct.
Key features
- Melting temperature up to 3500 °C; casting temperature up to approximately 1800 °C, with capacity depending on melting temperature.
- Double-walled water-cooled high-vacuum chamber and crucible, with a common solid holder for melting/casting inserts, electric chamber lift and movable water-cooled tungsten electrode.
- PLC with a 10-inch touch display; automated pumping/flushing, pneumatic casting-mould lift and changeover from melting to casting without conversion.
- Current bar graph, vacuum/pressure logging and maximum-current limitation facilitate handling low-melting materials.
- PLC safety functions include ignition-current limitation and monitoring of the eye-protection glass during ignition and melting.
- Suction casting is optional: a two-piece insert produces round or rectangular rods up to 170 mm long.
- Maximum pressure 1300 mbar is absolute pressure; 10–1000 A is a current range, not power in watts.
