Vacuum-assisted die casting is an important process capability at Kennedy Die
Casting.
The vacuum evacuation of the die cavity reduces gas
entrapment during metal injection and decreases porosity in the casting. The result is a
die casting with a higher level of quality.
Vacuum systems are only a supplement. They do not substitute for
good die casting design practice in the engineering of the die cavity, runners, gates and
overflows. |
Vacuum-assisted die casting was used for the fan housing, reducing porosity in the casting and producing high quality parts in
high volume |
