2. Transformation parameters
Whatever the plastic part to be produced, the processor has two parameters for setting the processing machines: temperature and speed. The permissible control range is relatively wide in the general case, but becomes significantly narrower when the parts are small.
2.1 Influence of speed
In extrusion, the transformation speed is given by the screw rotation speed, and in injection molding, by the injection speed.
Consider the following extrusion parameters:
he tooling air gap,
d characteristic dimension of the tool (e.g. tube diameter),
v draft speed,
Q material flow rate,dγ /dt average shear rate,...
