Hot Chamber ZINC Die Casting is a specific process that needs specific tools. Also simulation software must keep into account some critical elements which are peculiar of this process:
- The volume of the gas (air) to be evacuated is from 5 to 40 times the volume of the part itself (in cold chamber the same volume is 2-3 times).
- The process is extremely fast (ex. an aesthetic component is filled up in about max 20 ms and velocities over 50 m/s at the gates may generate turbulences, vortexes and then possible air entrapment).
- Temperature range between liquid and solid state is very limited (6-8 degrees C° vs. 50-70 C° of aluminum).
It means that gas entrapped in a metal which is already solid cannot be further evacuated.
Castle is the specific simulation software for zinc die casting.
