The VTC series: for every metal or alloy you want to cast.
The VTC 100 V – VTC 800 V are extremely versatile casting machines suitable for a wide range of applications – and a number of options that were considered mutually incompatible up to now. Thus, while the VTC series was originally designed as a high-temperature casting machine for casting steel, palladium, platinum etc. (max. 2,000° C), large flasks also make it suitable for economically producing castings in gold, silver, copper, aluminium and other materials.
The machine combines a dual-chamber differential pressure system with a tilting mechanism. The casting process is achieved by rotating the entire melting-casting unit by 90°. One benefit of the tilting system is the use of economically priced graphite or ceramic crucibles (without holes and sealing rods). These tend to have a longer service life. Some alloys, such as copper beryllium, quickly cause crucibles with holes and sealing rods to become untight and therefore useless. For this reason, many casters have so far processed such alloys only in open systems. But this means they can’t choose to optimise the process with overpressure or vacuum.
With the VTC series, these handicaps no longer apply. A vacuum can be produced in the melting chamber and the casting chamber to avoid oxidation processes during melting and air pockets in the casting mould. The flask is automatically pressed against the melting chamber for casting, this makes it possible to switch to overpressure during casting for better mould filling; in addition, the vibration technology optimises the process even further. As well as casting with flasks, casting into ingot moulds is also possible.
New sweep mode vibration system for perfect results even in Pt and Pd
Due to the advanced vibration technology working with variable frequencies and the sophisticated vacuum/pressure system, this machine is perfectly suited for casting platinum and palladium – and
all this without the elaborate and sensitive centrifugal mechanism usually required for platinum casting machines.

New generator system controlled via LCD display
A completely new generation of generator and control systems is present in the VTC series. Operation is simple and safe thanks to a clearly arranged and easy-to-use LCD display. All parameters, right down to the variable tilting speed, can be individually set and saved to ensure that recurring castings always produce consistent results.
