You can inject two to six different polymer materials within the
same cycle.
In the Study PropertyManager, under Injection
Process, select Multi Material
Overmolding. During a multi-material overmolding injection, separate
injection nozzles introduce materials sequentially into the cavities.
This injection process is available only with
the
Solid analysis procedure
and runs with the
Flow+Pack analysis
sequence.
The
Flow+Pack analysis sequence accurately
simulates an actual multi-material overmolding injection process. The first material
goes through a complete Filling, Packing, and Cooling cycle before the start of the
injection of the second material.
For two-shot or
multi-shot overmolding designs, you can use the Local
Gravity boundary condition to specify the gravity direction for each
cavity. This is useful in cases where various cavities have different orientations
in a mold and the gravity direction changes for each cavity.
