... solutions are similar to the previous cases except for the absence of the “dead” metal zone at the die walls. It was also suggested to use dies with round corner channels ( Ref 12 ). With low friction (τ≈0), the slip-line field ( Fig. 8 ) includes a central fan AOB and two separated circular slip lines...

The design of the runner and gate channels in the die that transmit liquid casting alloy to the casting cavity also differs in some ways from cold chamber dies. As in the cold chamber process, hot chamber die casting dies can be constructed in single-cavity...

The approach section ( Fig. 4 ) is the means for achieving these two needs. The shape of this section of the flow channel often provides the name of the gate...

... customer. Avoid channel segregation formation if possible. At regions in which the local cooling rate of the casting changes, such as at a change of section or at a chill or feeder, it is expected that a change in composition of the casting will occur.
