Moldflow develops plastic injection molding software.
A plastic in a mixed state of crystalline and amorphous conditions. Most plastics are semi-crystalline. The crystalline content determines the physical properties or the part.
See also crystalline.

A point is a position in space. The first stage of creating a model is usually the creation of points, which are then joined together to create surfaces.

A polymer is a natural or synthetic compound, usually of high molecular weight. Its long-chained structure consists of repeated linked molecular units called monomers (or mers). Monomers are relatively light and simple. A chemical polyermization process builds polymers from monomers.
Although the term plastics is often used as a synonym for polymer, plastics are actually one type of polymeric compound. Plastics are generally formulated with plasticizers, stabilizers, fillers, and other additives for the purpose of processing and performance.
Non-plastic polymeric systems include rubbers, fibers, adhesives, and surface coatings.
Processing polymers into end products mainly involves physical phase change such as melting and solidification (for thermoplastics) or a chemical reaction (for thermosets).

A preferred molding window is a refinement of a feasible molding window. It is represented by a set of boundaries that define a window-like shape. For the process setting ranges inside the preferred molding window boundaries, the molding process is optimal; outside the window boundaries, the molding process is not optimal, but it may be feasible.

A pressure profile is a graph made up of set points joined by lines. The set points determine the pressure to be applied at specific time intervals. The pressure profile controls how the part is packed out during the pressure stage of a cycle.
Industry:Software
A process window or molding window, defines the limits of molding conditions under which an acceptable part can be produced. If molding conditions fall within this region, then a good part can be made.

A process window or molding window, defines the limits of molding conditions under which an acceptable part can be produced. If molding 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.
