CAM

velocity stroke

Software; CAM

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 ...

viscosity

Software; CAM

The viscosity of a material is a measure of its resistance to flow within a mold cavity.

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 ...

viscosity index

Software; CAM

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 ...

zero screw position

Software; CAM

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'.

thermal degradation

Software; CAM

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, ...
