Company Profile:
Moldflow develops plastic injection molding software.
Routines are complete processes within Setup Xpert that optimize one aspect of a profile. There are six velocity routines that are used to optimize the velocity phase of the cycle, including the velocity stroke and the velocity profile. While the velocity profile routines are being used, the pressure profile is set to zero.

Runners are the channels that feed the polymer from the sprue to the gates of each cavity in the mold. A runner system includes the following: *Runners. *Gates. *Sprue.
Industry:Software
Screw displacement is the distance the screw has moved during the injection phase.
Industry:Software
Screw velocity is the speed with which the screw has moved during the injection phase.

Set points are the defining points on the velocity and pressure profiles. For the velocity profile, it is a discrete injection velocity and time/displacement coordinate. For the pressure profile, it is a discrete injection pressure and time/displacement coordinate.
Industry:Software
Shear is a type of deformation caused by friction between the moving plastic and the mold wall.
Industry:Software
Shear rate is the rate of change of shear strain with time.
Industry:Software
Shear stress is caused by friction between the moving plastic and the mold wall and between the layers of plastic moving at different rates. High shear stress can cause the plastic to degrade or to fail, due to stress cracks.

Shrinkage is the reduction in the dimensions of a plastic part, compared with the mold dimensions. Shrinkage occurs as the polymer cools. Shrinkage can vary in different directions. Crystalline and semi-crystalline materials are particularly prone to thermal shrinkage; amorphous materials tend to shrink less. Excessive shrinkage can be caused by the following factors: *Low injection pressure. *Short pack-hold time or cooling time. *High melt temperature. *High mold temperature. *Low holding pressure.
