Vakuumverguss + decontamination of the Vergusskomponenten
De-gassing of the casting compound can be manual
or automatic, where a vacuum can be simply generated in the vessel. Afterwards, the vessel
is vented and pressurized. Depending on the degree of automation of the blend and metering
equipment, this process is controlled automatically via a valve set. Casting is carried out
at atmospheric pressure or under pressure in the vessel. This standard is completely adequate
in most applications.
The casting material is de-gassed automatically as
described above. The vessel is at atmospheric pressure, or is pressurized. The vacuum level
(1000 - 1 mbar, absolute) can be programmed. Casting is carried out under vacuum, however.
In the simplest systems the casting nozzle is guided to the casting manually using rod control.
Electrically powered X- Y- Z axes and/or a circular indexing table are integrated in ultra-modern
automated systems. The parts to be cast are docked using valves and distributor systems and then
filled with casting compound. The vacuum chamber can be flushed out under vacuum using our poison
class and VOC-free flushing material.
Automatic casting as described above, but with
continuously driven recirculation pumping of the casting material under vacuum. The holder
refilling is carried out automatically, even during the casting process. In such cases the
components are sucked into the holders using vacuum, or pumped in, and de-gassed automatically
using a thin film de-gassing system.
