Information for the

autocast universal

230

Casting Unit

Casting with Titanium

Due to the high melting point of titanium, the autocast

universal

230 unit is equipped with a highly efficient melting

system that supplies the energy necessary for melting the

titanium within a very short period of time. When the start

button is pressed, the entire melting and casting process

takes place automatically.

The complete melting/casting process takes place in an

enclosed double chamber system. The melting chamber is

filled with argon gas and the casting chamber is under

vacuum. The titanium is placed on a copper crucible.

The skull melting process leaves the crucible undamaged

because the titanium melt is enclosed within a shell of solid

material. An electric arc melts the metal within a given

period of time. The melting period depends on the amount

of metal to be melted. Once the degree of liquidity for

casting has been reached, the melt is tipped under pressure/

vacuum assistance via an argon flush into the muffle.

Casting with Alloys

Contrary to casting with titanium, the output of the electric

arc is individually set depending on the alloy used. The alloy

is melted on a special ceramic crucible under visual control

and then tipped when the right casting moment has been

reached.

Requirements for a universal melting and casting unit for use

in the dental field, are:

• Safe and reliable casting of titanium and other alloys while

retaining all their characteristics.

• Compact size for accommodation in the dental laboratory.

• The autocast universal

230 has a low energy consumption.
