Indutherm VC 680 V - Fully Automatic Vacuum Gold Casting Machine with Vibration Technology

Refilling Without Loss of Temperature or Pressure

The Indutherm VC 680 V features an innovative automatic feeding system that allows metal to be added without opening the melting chamber. This prevents heat loss, maintains chamber pressure, and eliminates unnecessary energy consumption.

Equally important, no oxygen enters the melting chamber during refilling. This means the chamber does not need to be re-evacuated or re-filled with inert gas, resulting in much faster casting cycles. The stable atmosphere and temperature also extend the service life of the crucible and sealing rod.

An automatic metal sensor notifies the operator when the feeder requires replenishing.

Automatic vacuum and overpressure

The vacuum in the melting chamber ensures that the metal is degassed and prevents unwanted oxidation during melting (an oxygen-poor atmosphere is particularly important when melting copper-containing alloys). The vacuum in the cuvette chamber improves mold filling, especially when casting delicate parts, and prevents annoying air pockets.

In addition, the system switches to overpressure in the melting chamber, thus increasing the pressure difference. An additional integrated pressure tank  provides even faster overpressure build-up for activation of the TurboPressure PLUS function.

Dual Temperature Control

Temperature is measured both in the crucible wall and in the crucible center (within the closure rod). This dual measurement ensures reliable accuracy and strict adherence to your selected temperature range.

Temperature Measurement for Filigree Work

Cuvettes with incorrect temperatures can be a significant safety risk. Precise flask temperature is especially critical when casting small or intricate components.
Temperature measurement in the flask (standard on the VC 650 V and VC 680 V) now allows readings with one-degree accuracy, dramatically improving casting safety and consistency.
