description

Injection molding tests were performed on a Ny 66 resin. Data are presented on the mass entering the mold during the packing-holding stage as a function of filling flow rate and holding time. The experimental results are discussed on the basis of a simple model of the packing-holding stage. Only a small part of the density increase due to crystallization seems to be compensated by extra flow during the packing-holding stage.
