Moldflow develops plastic injection molding software.
The viscosity of a material is a measure of its resistance to flow within a mold cavity.
Industry:Software
The viscosity of polymers is dependent on temperature, pressure and shear rate. The relationship of the variables can be described by one of several equations, called models. For this product you can use either the Cross-WLF or the Second Order model.
Industry:Software
The viscosity of the material at 1000 1/s shear rate and at a specified temperature.
For example, VI(240)125 means that the material has a viscosity of 125 Pa.s at a shear rate of 1000 1/s and a temperature of 240C.
The viscosity index is used to compare the viscosity of one material to another.
Industry:Software
The zero screw position is the furthest forward position possible for the screw. This is when the end of the screw is in contact with the barrel or hits machine 'stops'.
Industry:Software
Thermal degradation is a break down of material quality, resulting in poor parts. Thermal degradation may occur if the barrel temperatures are too high, the rotational speed of the screw is too fast, or the nozzle diameter is too small.
Industry:Software
These curves and the surfaces that are formed from them follow no mathematical relationship.
Industry:Software
This is the name of a family of materials, for example, Polycarbonate. Each material is a member of a family of materials.
The shortened version of a family name is the family abbreviation. For example, PC is the family abbreviation for Polycarbonate.
Some families contain subsets, and there is an abbreviation for each subset. For example, TPE, TPO, TPU, and TPR are family abbreviations within the Thermoplastic Elastomer family.

This is the position of the screw when the machine switches the screw displacement control from velocity control (used in the filling stage), to pressure control (used in the packing stage.)

Unbalanced flow occurs when polymer melt completely fills some flow paths in the mold before other flow paths have filled.
