The thermoplastics injection-molding process of has become one of the most important polymer processing operations in the production of molded parts with geometric complexity and high precision.

Modeling and computer simulation of this process is not an easy task. Commercial computer packages have been designed for the simulation of the injection molding process. These programs allow the determination of the effects of operational conditions on the quality of molded parts. However, they require a high demand of computing time, and their costs restrict its use to companies with financial capacity.

FEMLAB offers graphical and computational tools that can be implemented for analysis and design of a variety of cavity geometries and visualization of some process characteristics.
