Valve Controller BC

Analysis > Molding Loads > Valve Controller

Description

This BC is typically applied at the interface between the hot runner and the cold runner/part.

A valve can exist in two states:
  • open
  • closed

Its state also depends on whether it is filling/packing/cooling phase.

The state of a valve can be changed using a variety of controls and they are applied in sequence.

Controller type

  • Flow Front Location:

    Select a node and specify the valve state. When the flow front reaches that node, it will open/close the valve. This is an often-used condition.

  • Time Controller:

    Specify the time to open/close the value surface. This is also an often-used condition.

  • Value Controller:

    The value considered is always pressure in this release. User can select a node, specify pressure value and condition Based on that the valve is open or close

  • Percentage Filled Volume:

    Specify the 3D part and the percentage of filling. Once that part/assembly is filled to the specified percentage, it will open or close the valve.

These controllers can be applied in sequence on each valve surface.
