•Most common manufacturing processes for plastic parts involve liquid shaping and solidification.
•The most important material property influencing shaping is the viscosity
•The viscosity of plastics differ from common materials due to their long molecules: Viscosity of Plastics decreases with increasing rate of deformation
•During Shaping, viscous forces are much larger than inertial forces
•Due to their long molecules, liquid plastics have some elasticity
•The most important material property influencing solidification is the thermal conductivity
