DEFINITIONS
USED FOR COLD CHAMBER MACHINES: |
This is an explanation of the terms used to classify
Cold Chamber die casting machines. All cold chamber die casting machines fall
into one of these three categories.
|
|
MACHINE
CLASSIFICATION: |
FULLY AUTO:
This term means that the die casting machine can perform the whole casting
process (mentioned below) "automatically" without operator intervention or help in the form of
manual labor. As such, in order for the machine to be called "fully automatic"
the machine must include all three (3) automatic devices; an automatic
mechanical ladler, an automatic mechanical sprayer and an automatic mechanical
extractor.
SEMI AUTO:
This term means that the die casting machine can perform only one, or at the
most two, of the die casting processes (mentioned below) without manual labor by the operator.
The rest of the process requires manual labor by the operator. In order for the
machine to be called "semi automatic" it must include at lease one (1) or at the
most two (2) automatic devices; an automatic mechanical ladler, an automatic
mechanical sprayer or an automatic mechanical extractor.
MANUAL:
This term means that the die casting machine cannot perform any of the die
casting processes (mentioned below) automatically. All three processes, ladling, spraying and
extraction must be done by the operator.

|
COLD
CHAMBER PROCESS: |
The process of Cold Chamber die casting requires
three (3) distinct functions.
|
|
|
1) Ladling: The process of transferring the
molten metal from the furnace to the shot sleeve. This process can be done
manually by the machine operator or automatically but a mechanical ladling
device.
|
|
|
2) Spraying: The process of spraying die
release liquid or compound on one or both sides of the die before the next cycle
starts. This process can be done manually by the machine operator or
automatically by a mechanical spraying device.
|
|
|
3) Extraction: The process of removing the
finished casting from the die before the next cycle starts. This process can be
done manually by the machine operator or automatically by a mechanical
extracting device. |
