Supervision of injection mold quality

Polimery 1999, No 4, 262

DOI: dx.doi.org/10.14314/polimery.1999.262


Supervision tasks are discussed, comprising the injection molding process. Variability of injection molding parameters is emphasized observed, in the production of identical products over five days (Figs. 4 and 5) and even within one day. The major factors governing injection molding are mentioned and illustrative relationships between selected process parameters (product mass in relation to time, to screw rotation speed and to injection energy index) are given. An information system is suggested, useful for automated supervision of the injection molding process (Figs. 9 and 10).
