Vacuum investment casting is the process used in lost-wax technique to replicate in metal a wax or resin pattern.
The shape is designed and then built in wax or resin by different equipment as CNC, 3D printers, by means of wax injection in a mould, or even manually. You may use either investment molds or metal permanent molds.
Furnaces or complete foundries setup for any casting application of magnesium, alumunium, bronze and brass .
For non-ferrous metal powder production, TOPCAST has developed water and gas Atomizing Furnaces, complete with cyclone filtering system and dryer for a key in hands solution. Bronze powders are commonly used in SLM systems for 3D rapid prototyping,
For use in processes like non-ferrous metal refinery, recovery, alloy homogenization and scraps melting, TOPCAST proposes its wide line of Medium Frequency Induction Melting furnace ranging from 5 kW to 500 kW.
Joystick assisted crucible tilting mechanism is provided with either electro-mechanical or hydraulics control. Hand-whell tilting also available on smaller furnaces.
For nonferrous metal assay and test, TOPCAST proposes a specific pressure over vacuum casting machine for XRF analysis sample preparation.
Small melting furnaces with manual extraction of the crucible are also available for the homogenization of the samples coming from a scrap batch.
