The photos show the two die halves -- the cover half and the ejector half.
Note how each die
insert is contained in the larger, heavier die frame.
proprietary steel alloy, the diecasting tool has a
demonstrated life of over 150,000 "shots" before tool
refurbishment is necessary.
This is a 4X
improvement in tool life compared to standard tool steels and
is a major cost savings over the production life of the heat
aluminum enters the die cavity at over 850C/1200F.
die casting operation, the temperature of the tool is
controlled with active water cooling through channels in
the die frame. This prevents excessive
heat-build up and thermal damage to the tool. (The cooling
line connections are seen on both sides of the die frames.)
