Profiles are used to ensure that the simulation matches the actual molding process as accurately as possible.
Ram speed, velocity or filling profiles are used in the filling phase to control the movement of the screw. Pressure or packing/holding profiles are used in the packing/holding phase to control the packing and holding pressure applied to the mold. The change from velocity to pressure profile control occurs when the velocity/pressure switch-over point is reached. Both types of profiles help reduce mold defects such as flashing, short shots, jetting, burning, sink marks, warpage, flaking, and more.
Temperature profiles are used to simulate the surface temperature of zones of the mold through the injection cycle.
Gas profiles are used to control the injection of gas when simulating gas injection molding.
