Vacuum Casting of Metallic Components Induction Melting Vacuum investment casting is the process used in lost-wax technique to get a metal part as a copy of a wax or resin pattern. The pattern is designed and then manufactured in wax or resin materials by different equipment as CNC, 3D printers, wax injection in rubber or metal molds or even carving manually the wax part. Molten metal can be poured in vacuum either in shell, investment block mold or solid permanent molds. Furnaces and complete foundries setup for casting can be supplied for any application. In detail, TOPCAST offers the...

Vacuum casting of metallic components TVCd | Double chamber pressure over vacuum casting machine TVCd is the pressure over vacuum casting machine designed to meet the more severe needs in lost wax casting production. This machine 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 melting chamber and flask chamber are completely independent and at the moment of casting the machine controls the metal injection into the mold by applying a...

Technology, features, technical data Gas Wash Procedure Crucible loading operation introduces oxygen The Gas Wash Purge procedure removes the oxygen (1) in a very fast and efficient way and then refills back the chambers with Argon or Nitrogen gas (2) Compared with the traditional crucible protection by dilution, the consumption of gas is dramatically reduced and the alloys oxidation is minimized; moreover the crucible life is increased Model Crucible volume Advanced Self Tuning thermoregulation (AST™) with exact temperature control of the melted alloys Two Set-Points available:...

Vacuum casting of metallic components TCE | Vacuum centrifugal casting machine TCE are consistent, robust and easy to use vacuum centrifugal casting machines designed for small and medium casting laboratories. They can be manufactured in Class A or B. TCE in Class B are particularly suited for Platinum, Palladium and Steel while TCE in Class A has been especially designed to cast Titanium, Inconel and amorphous metals. All models can also melt nonferrous and precious metals. The main difference between TCE in Class A and TCE in Class B is the degree of vacuum, leak-back rate and ppm of...

Vacuum casting of metallic components TVM | Vacuum induction melting machine Topcast TVM are VIM furnaces conceived in a closed environment designed to melt and pour any kind of alloys under high level of vacuum. In particular, TVM is the right choice when large batches or mass production is required. A 20 kg Pt crucible capacity for high quality sheets aimed to produce Pt and Pd ingots is the most common application in precious metals. TOPCAST develops this class of furnaces under customized specifications for what concerns crucible capacity, mold size and vacuum level. In case you are...

TVM furnace is conceptually divided into 5 sub-systems: Vacuum Melting Chamber with optional alloy feeding chamber and sampling probe Induction Generator Tilting Coil and Crucible Assembly Casting Mold in Graphite, Ceramic or Metal, also water cooled 05. Vacuum Pumping Station TVM technical data Model Crucible Volume Induction Power Ultimate vacuum level Max. temperature Industry 4.0 / Remote Interface Fully water-cooled 24/7 Main alloys Ni-based alloys, Reactive metals Available on request

Vacuum casting of semi-finished products TIP | Vacuum furnaces for ingots TIP furnaces are designed to manufacture any size of ingots, from 100 g to kilo-bar either in gold or silver. Ingots are obtained by melting preweighted grains in a graphite mould placed inside the vacuum chamber and then by cooling appropriately the ingot during the solidification phase. The machine is fully automatic having more than 100 programs for different ingot sizes. The operator only has to load the graphite mould with pre-weighted grains into the holding disk, close the loading chamber and press the START...
