Moldflow develops plastic injection molding software.
A process window or moulding window, defines the limits of moulding conditions under which an acceptable part can be produced. If moulding conditions fall within this region, then a good part can be made.

A process window or moulding window, defines the limits of moulding conditions under which an acceptable part can be produced. If moulding conditions fall within this region, then a good part can be made.
On the graph below, a good quality part (labeled with a checkmark), is encircled by the boundaries of the process window. A poor quality part (marked "X"), is outside the process window.

A production run is a series of parts made under a particular set a process conditions, for example, a particular set velocity and pressure profiles.
Industry:Software
A rectangular surface defined by a grid of points which represent the control points of a NURBS definition of a surface. (NURBS is a Non-Uniform Rational B Spline, a common mathematical representation in the CAD industry.)
NURBS surfaces are not often used, because they are limited to a rectangular shape. Trimmed surfaces are more useful and common.
Surfaces provide important information for meshing operations, which allow much better meshes to be achieved than via facet-based mesh input.
See also trimmed surface.

A restricted gate is a small opening between the cavity and runner in an injection mold. The gate breaks cleanly after each part is made to assist part recovery.
Industry:Software
A rib is a long, thin intersecting wall that is used to reinforce the outer walls of the plastic part.
Industry:Software
A short shot is the incomplete filling of a mould cavity which results in the production of an incomplete part.
Industry:Software
A single sub-domain of a finite element mesh. Elements typically used in moulding simulation are:
*Two-node linear elements, used to represent runners, cooling channels and connectors.
*Three-node triangular elements, used to represent surfaces.
*Four-node tetrahedral elements, used to represent solids.
The properties of the element are assumed to be homogeneous.

A transducer is a mechanical or electrical device that is used to measure a value and transmit the measurement to a recorder, or to a device that can compare the measurement with a desired value.
Industry:Software
A trimmed surface is a NURBS surface with a set of curves defined in the UV space of the surface. This provides an easy way to define non-rectangular representations (patches) of surfaces.
(NURBS is a Non-Uniform Rational B Spline, a common mathematical representation in the CAD industry.
