Agatronic G, H and R series devices are vacuum casting units combined with an induction furnace. The machines have been designed to fulfill three basic functions. Small structural modifications enable the user to quickly adapt the device to make high quality castings using the investment casting method, to make grain with a small ball structure and to use the machine as an ordinary melting furnace.

An undoubted advantage of the bottom drain casting is the difference in the densities of metals and impurities present in them. As soon as the metal goes into the liquid phase, the impurities flow to the surface. While pouring metal from the so-called "hand" these pollutants get into the die and are closed in the structure. By pouring the metal through the hole in the bottom of the crucible, the impurities remain in the crucible or they pollute only the entrance of the die. The obtained product gains a more cohesive structure and is easier to be processed further. An additional advantage is a certain, uniform and uninterrupted stream of metal.

The devices are equipped with a process controller monitoring the generator power, the temperature regulation and the device status itself. The messages are displayed on the LCD display in several available languages.

These casting machines are designed to operate in small jewellery companies for casting of individual products, casting of metals with a high content of zinc, especially in the bronze industry.
