Moldflow develops plastic injection molding software.
The shot size is the distance between the screw back position and the zero screw position of an injection molding screw. This is a measure of the polymer available for injection for each part.
Shot size is also known as charge stroke.

The specific heat (Cp) of a material is the amount of heat required to raise the temperature of a unit mass of material by one degree Centigrade. It is essentially a measure of a material's ability to convert heat input to an actual temperature increase. It is measured at zero pressure and a range of temperatures, or averaged across the temperature range of 50C to the material's maximum processing temperature.
The unit of measure for specific heat is J/kg-C, Joules per kilogram celsius.

The sprue is the main feed channel that connects the mold cavity with runners leading to each cavity gate.
Industry:Software
The start of fill is the time at which melted polymer starts to flow. This happens after the screw has started to move and corresponds to the start of the pressure rise in the nozzle.
Industry:Software
The stroke is the distance between the screw back position and the screw forward position of an injection molding screw. This provides a measure of the amount of polymer injected during a cycle.
Industry:Software
The thermal conductivity of a material is the rate of heat transfer by conduction per unit length per degrees Celsius. It is expressed in units of W/m.°C. It is essentially a measure of the rate at which a material can dissipate heat, and is determined under pressure and averaged across the material's melt temperature range.
Industry:Software
The time required for the injection molding machine to fill the part.

The transition temperature is the polymer freeze temperature. At this temperature, the melt-to-solid transition occurs.
The transition temperature corresponds to the glass-transition temperature (Tg) for amorphous materials and to the crystallization temperature (Tc) for semi-crystalline polymers.
Industry:Software
The velocity profile is a graph made up of set points joined by lines. The set points determine the velocity to be used at specific displacement measurements. The velocity profile controls how the part is filled during the injection stage of a cycle.
Industry:Software
The velocity stroke is the distance between the screw back position and the velocity to pressure change-over position in an injection molding machine. This is the proportion of the total stroke performed under velocity control.
