Flask (rotary switch):
By using this rotary switch, select if the flask is to be
evacuated or ventilated.
Locked-
Standard position to add or remove the flask
into the vacuum chamber.
Vacuum-
After putting in place the flask, the vacuum is
turned on. Approx. 20 seconds afterwards the casting
process can be started.
Release- Having this position the vacuum chamber will be
filled with protective gas.
Flask:
When this switch is in upper position, the pneumatic cylinder
installed in the vacuum chamber rises so that the flask can
be taken out easily.
When putting in a larger flask, the cylinder should be in high
position.
When now turning the FLASK switch, the flask moves back
into the vacuum chamber.
Vacuum chamber: When this pneumatic switch is in upper position, the vacuum
chamber is lifted, so that
– when the chamber is closed – the
whole casting area is sealed. When moving the switch down,
the vacuum chamber moves to lower position and can then
be moved aside.
Main switch: The machine is turned on/turned off by turning this switch.
- Granulating tank (option):
Regulate the water stream in a way that the water is in motion, but does not
sprinkle.
After the granulating process the metal can be taken out by lifting out the insert.
4.2 Casting
Before starting check crucible, sealing rod and crucible insulation for dirt
residues/possible damages. It is recommended to use a
vacuum cleaner to clean the
entire inductor. The metal filter (left of the sealing rod) should be taken out and cleaned
with compressed air.
A suggestion for a general casting process (vacuum in flask, normal pressure in
crucible):
1.
Open cooling water, compressed air and protective gas supplies.
