Casting Tools and Products

Indutherm MC 16

Suitable for smaller production runs, the Indutherm MC 16 is a tabletop vacuum casting machine capable of reaching a maximum temperature of 2,000°C (3,632°F), allowing it to cast all standard alloys, including gold, silver, platinum, palladium, and steel. After pouring, the MC 16 automatically switches to overpressure to optimize the mold filling even for delicate parts such as filigree. Designed to be easy to use, the unit includes an LCD display that features all of the program data. Measuring 40 cm wide by 45 cm deep by 40 cm high (15.7 inches by 17.7 inches by 15.7 inches), the MC 16 can cast a maximum of 100 grams of gold or silver and up to 200 grams of platinum.
