TVCd-XL is a family of pressure over vacuum casting machines designed to meet the more severe needs in lost wax casting production of aluminium, bronze, steel, magnesium alloys. They are often used in connection to a 3d printer for direct casting to get metal parts of complex objects.
This family of machines works with a new, revolutionary double chamber concept. This innovative system gives several advantages compared with the traditional single chamber suction system currently available in the market.
In TVCd-XL, melting chamber and flask chamber are completely indipendent: while casting, the machine can control the metal injection into the mold by applying a differential pressure during pouring. This yields to a faster injection compared to the simply gravity pouring with the benefit to cast items at lower temperature. This will result in better surface finishing and reduced shrinkage of the cast parts.
The casting cycle takes only few minutes and, while the previous flask is cooling down in protective gas for no oxidation, the next charge can be loaded into the crucible and melted, thus overlapping two cycles for no time waste.
The machine is fully automatic, featuring a PC based monitoring system for process parameters acquisition and production data management, with easy editing of casting programs suitable for many kind of alloy.
This revolutionary machine is the synthesis of the most advanced engineering and years of experience in casting that only TOPCAST will bring in your factory.
