Vacuum Melting & Casting

Non Ferrous Metals

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 rapid prototyping of parts in aluminum, bronze, brass, magnesium, used for example in the aerospace, automotive and medical, TOPCAST may offer:
  • TVC-XL vacuum casting machines (dual chamber system) for particular jointed and free of porosity;
  • TCE centrifugal vacuum casting machines for high performance levels of the metal, thin and large surfaces, difficult and detailed parts;
  • FCC burnout furnaces for wax / resin removal and refractory mould baking.
TOPCAST also provides installation and commissioning on site.

Induction Melting

Non Ferrous Metals

TOPCAST induction furnaces can be used for melting nonferrous metals (brass, bronze, aluminum alloys).
The smaller models are with manual extraction of the crucible, the larger ones are tilting crucible.
Are also available closed chamber furnaces for alloys that require melting under vacuum or in a protective atmosphere.
TOPCAST’s induction furnaces design uses the latest and most advanced IGBTs modules available worldwide.
IGBT-based proprietary design, high-performance induction generator is equipped with soft-switching and frequency automatic tracking technology.

Powders / Atomizer

Non Ferrous Metals

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,

Recovery & Refining

Non Ferrous Metals

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.

Assay & Test

Non Ferrous Metals

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.
