Automatic Valve Gates

An option automatically defines control valves so you can predict the control valve opening times based on the melt front arrival.

Valve gates are used with hot runner systems to sequentially inject plastic at several locations in the cavity. Plastics simulation can help determine the timing sequence for opening each valve. Two options make these simulations easier.

In the Injection Location PropertyManager, click Automatically Add Valves to let the program define control valves at the common interfaces between runners and cavities. You no longer need to select mesh elements manually, when you activate this option.

By selecting Automatic under Valve Open Range, the control valve opens automatically when the melt front passes the gate. You can then view the predicted opening times of each control valve in the log file.
