Moldflow develops plastic injection molding software.
The screw back position is the position that the screw is brought back to before the start of the next cycle.
Industry:Software
The screw forward position is the furthest forward position of the screw during a cycle.
Industry:Software
The screw is the part of the injection moulding machine that pushes the polymer into the mold, that is, the shaft that rotates within the barrel of the injection moulding machine to process and prepare the material for injection.
Industry:Software
The shear strain of the polymer is the ratio of the deformed state compared to the original state, when a polymer has been deformed due to an applied load.
Industry:Software
The shot size is the distance between the screw back position and the zero screw position of an injection moulding screw. This is a measure of the polymer available for injection for each part.
Shot size is also known as charge stroke.
Industry:Software
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 kilogramme celsius.
Industry:Software
The sprue is the main feed channel that connects the mould 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 moulding 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.
