VC-Series

Highly efficient operating concept

The right machine for every application

The range of our VC series systems extends from small to very large capacities, from semi-automatic systems to solutions for fully automatic casting production. Sophisticated functional details create the basis for optimizing each casting for its individual properties.

Separate locking systems for “overlapping” casting

All Indutherm VC systems have separate locking systems for the melting and cuvette chambers, enabling significant time savings through “overlapping” pouring: While the cuvette remains in the vacuum chamber for a few minutes after pouring, the next batch can be filled and heated up.

Pneumatic bell lock and automatic locking system

The melting chambers of all VC systems are closed with a pneumatic system. VC 650 V and VC 680 V are also equipped with an automatic locking system.

Automatic cuvette and chamber lift

To swivel in the vacuum chamber, the cuvette inserted is lowered and then docked automatically. When the chamber is opened, the cuvette is raised for easy removal. This means the economical cuvettes can be used without a flange.

Program control for fast and certified productions

Thanks to the control panel with full-text LCD display, all programs and parameters can be set very easily and practically. The semi-automatic systems have temperature programs. The fully automatic systems have a program control system that includes all parameters.
Up to 100 casting programs ensure quick operation and uniform casting results. The parameters are pre-programmed for the most important alloys, e.g. B. for AGS, Alpha Plus, Heraeus, Legor and
Pandor alloys. In practice, this means: Good casting results can be expected from the first cuvette without expensive preliminary tests. The program control and the built-in data printer ensure a high level of security and precise process logging.

Ready for future standards

Like all of our systems, the VC series is equipped with software and interface management that allows remote maintenance and service and forms the basis for future networking with other systems.


Controlling the pressure conditions – important for the perfect casting result

Automatic vacuum and overpressure in the melting and cuvette chambers

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.

Oxidation reduction after casting

This special system eliminates the risk of oxidation while the cuvette cools.

Turbulence reduction software

TRS ensures a faster and more consistent flow of metal. It improves mold filling and prevents parts of the plaster mold from breaking off at critical points and becoming trapped in the casting.

Turbo Pressure / Turbo Pressure PLUS

The turbo pressure function optimizes the casting of very small and delicate objects and guarantees perfect casting with stones in jewelry production. With Turbo-Pressure, a precisely defined and extremely rapid pressure build-up is achieved during pouring. With all program-controlled VC models, Turbo-Pressure is automatically started at the same time, exactly to the second, depending on the program. The Turbo Pressure PLUS system also allows higher and faster pressure build-up.

HSC – High Speed Casting

HSC improves mold filling and surface quality of small parts or those with large and smooth surfaces. HSC makes it possible to cast processed colored stones at low temperatures.

Precise temperature control

Dual temperature control

The temperature measurement in both the crucible wall and in the crucible center (integrated in the closure rod) ensures strict adherence to the preselected temperature range.

Cuvette temperature measurement

Up until now, cuvettes with incorrect or different temperatures were a safety risk. When casting very small or delicate parts, the correct cuvette temperature is crucial. Measuring the cuvette temperature (standard for VC 650 V and VC 680 V) now provides the decisive plus in safety: the temperature of the cuvette can be checked with an accuracy of one degree.

Vibration technology for better casting results

The Indutherm vibration system

  • Vibration during casting improves material flow and thus mold filling.
  • The density of the castings is higher and more uniform.
  • The porosity is significantly reduced.
  • 50% smaller grain sizes
  • reduced risk of breakages (hot cracks)
  • Cast parts have better tension and elastic properties, which makes them easier to process

In practice this means: higher and more consistent quality, less scrap, less post-processing, better formability. A customer in the USA found that the Indutherm vibration technology reduced overall production time, including post-processing, by 25%.

Other Advantages of VC-Series

Longer consumable life can be achieved by reducing frequent temperature changes and exposure to oxygen as much as possible. For this reason, we offer filling devices for numerous system models that enable recharging without loss of temperature and without contact with oxygen.

Our self-developed generators and induction heating systems tailored to the intended use ensure maximum energy efficiency. They not only reduce power consumption, but also increase the heating speed and the maximum temperature. They also reduce electromagnetic emissions with regard to the EMC directive. Efficient encapsulation ensures that the induction generated is used with as little loss as possible for rapid melting of the metal. The thermal insulation around the inductor and crucible protects against heat radiation. This high use of energy also reduces the energy consumption for water recooling in the machine and for any air conditioning that may be necessary in the foundry.

Program control system for fast and certified casting processes. Thanks to the control panel with full text LCD display, all programs and parameters are very easy and convenient to set. The semi-automatic machines offer temperature programs. The fully automatic machines have a program control system involving all parameters. Up to 100 casting programs guarantee fast operation and consistent casting results. Parameters are pre-programmed for all major alloys, e.g. for AGS, Alpha Plus, Heraeus, Legor and Pandora alloys. In practice this means: from the first mold, you can expect good casting results without carrying out expensive pre-tests. The program control and the integrated data printer ensure a high level of safety and the possibility of precise process documentation (important for certified casting processes).

All Indutherm VC machines have separate lock systems for the melting chamber and mold chamber. This allows time to be saved by “overlapping” casting: while the mold remains in the vaccuum chamber for several minutes after the casting, you may fill in and heat up the next charge.

The filling device means there is no need to open the melting chamber for refilling. This way, the melting chamber temperature remains high and unnecessary loss of energy is avoided. Most importantly: No oxygen enters the melting chamber so the chamber does not need to be evacuated again and refilled with inert gas. The advantages: lower personnel costs, more consistent casting quality, better process stability, less waste, optimised overlapping casting, up to 20 casting cycles per hour, high energy efficiency, longer service lives for consumables, minimised metal loss, replenishment without loss of pressure.

Numerous measures in our casting systems reduce metal losses during the casting process to an absolute minimum. These include, among other things, the sophisticated overpressure and vacuum controls, the anti-oxidation system, the vibration system and, last but not least, the high-quality materials of the crucibles and sealing rods.

Up to 20 casting cycles per hour thanks to programmable overlapping casting and optional automatic feeding devices.
