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. These machines combine a dual-chamber differential pressure system with a tilting mechanism. Some alloys, such as copper beryllium, quickly cause crucibles with holes and sealing rods to become loose and therefore useless, and for this reason, many casters have so far processed such alloys only in open systems “ which means they can't choose to optimize the process with overpressure or vacuum. With the VTC series, these handicaps no longer apply.
Creates 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
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.
Highly reactive metals such as titanium pose particular challenges when casting. The atmospheric conditions in a 'normal' vacuum pressure casting machine are completely inadequate for smelting and casting titanium, and the crucibles and molds need to be made of specific materials. Hence until now the only way to cast titanium was to use extremely expensive specialized machines. The VTC V Ti machines are not only suitable for casting titanium - they can also be used for any highly reactive metal or alloy, such as copper, beryllium, etc.
Featuring completely reconstructed valves and hose connections, special seals and evacuation and inert gas flushing process tailored to the machine, the Ti option is capable of creating a vacuum of 10-7 bar required for titanium casting. special crucibles and inductors were developed for the Ti versions, as the ceramic crucibles that are normally used also react with titanium to varying degrees. The new materials also reduce smelting times - and the shorter the smelting time, the less time there is for a possible reaction.
By rotating the entire melting-casting unit by 90°, economically priced graphite or ceramic crucible can be used, which have a longer service life. 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 mold. 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. vibration technology optimizes the process even further. As well as casting with flasks, casting into ingot molds is also possible.
