Moldflow develops plastic injection molding software.
A line in three-dimensional space. A curve can be straight or contain bends.
This includes:
*Line - a straight curve defined by two end points
*Arc - a section of a circular curve defined by one of two methods:
**Three points on a plane
**A centre point and arc and angle
*Spline - a cubic spline interpolation. on a supplied set of points.

The cushion is the distance between the forward screw position and the zero screw position, and contains polymer left in the barrel after the cavity is filled. Most of the melt in the cushion is then used for compensation flow during the packing stage.

Cycle time is the time from the ejection of one part to the ejection of the next part. Cycle time is the sum of:
*Filling time
*Packing time
*Cooling time
*Mold open time.

Decompression is the movement of the screw away from the nozzle (without rotation) and is used to prevent drooling. Decompression may be used for low viscosity materials (for example, PA-66), where the nozzle does not have a valve gate to prevent drooling.
Industry:Software
Delamination is a localised separation of the surface of the part. The most common cause of delamination is excessive injection velocity.
Industry:Software
The density of a plastic part is measured by dividing its mass by its volume. A denser part has more plastic molecules and more weight per volume. A part can have some regions with higher density than others.
Industry:Software
A disc gate is a mould gate used in an identification of a moulded part, generally having the same cross-section as the mould runner.
Industry:Software
The dominant flow path is the flow path of least resistance (the smallest pressure drop) from the polymer injection location to the last place to fill. In the graphic below, the cone indicates the injection location and the X indicates the last place to fill.
The dominant flow path is normally, but not always, the longest flow path.
Industry:Software
The angle included in the part design to allow the part to be easily ejected from the mold.
Industry:Software
Drooling is leakage of polymer from the nozzle, sprue, or gate. This creates thin strands of plastic that can get caught in the mold.
