Moldflow develops plastic injection molding software.
A boundary representation solid is a model format produced from a surface modelling CAD system. The solid is defined as a list of surfaces that enclose a volume.

A b-spline is a mathematical function that defines free-form curves and surfaces. IGES files that use b-splines instead of parametric splines are generally smaller in size.

A bubble is a spherical, internal void caused by air or other gas trapped within a moulded plastic product. A bubble differs from a blister in that the bubble is contained within the part, whereas a blister is on or near the surface of the part and generally causes deformation of the surface. A bubble also differs from a void, which is developed as a vacuum during cooling.

A bubbler is cooling system component. It is a central circular channel that can be introduced into the mould and is used to regulate and direct the passage of coolant fluid, so that the coolant can travel into difficult areas for more efficient cooling. The coolant flows through the central channel and then out and around the outside of the channel to the outlet point.
Both baffles and bubblers have the effect of increasing flow turbulence and thus increasing heat transfer due to the inclusion of additional bends in the coolant flow system. Their geometrical shape also enables the application of cooling to restricted areas.
Industry:Software
Buckling is the conversion of in-plane membrane energy to bending energy and usually involves large deformations of the part. It is the principle mode of failure of a planar thin structure under excessive in-plane loading.
Industry:Software
A burn mark is a defect that appears as a brown or black mark on the part surface. A burn mark can be caused by an un-vented air trap. This occurs when the trapped air is heated very quickly as it is compressed, burning the surrounding plastic. Velocity profiling is often used to prevent this problem, by giving air more time to escape from the mold.
Industry:Software
Computer-Aided Design (CAD) is the process of using computer software programmes to design parts, tools, molds, and assemblies.
Industry:Software
Computer Aided Manufacturing (CAM), is the use of computers and computer technology to control, manage, operate, and monitor manufacturing processes.
Industry:Software
The cavity is the region within the mould that fills with plastic to form the part.
Industry:Software
A centre gate is a gate which is located in the centre of the part. It can be a sprue (direct) gate or pinpoint gate.
