Flow of Polymer Melts in Runners of Injection Molds

Popis výsledku v původním jazyce

Injection molding is one of the most extended plastic processing technologies. Delivery of polymer melts into the mold cavity is the most important stage of the injection molding process. In the mold cavity the melt freezes and the product gain the finalshape and form. Plastic material does not slide along the mold surface but is instead rolled over much like rolling out a carpet. This type of laminar flow is usually described as a "fountain flow". Unusual (not expected) behaviour of polymer flow usingvarious quality of surface of spiral walls was observed. Better quality of wall surface made flow condition worse (the length of injected sample was shorter). Measurement shows that quality of surface affects on the length of flow. To verify these results it has to be made further experiments where the materials (polymers) and testing conditions will be widely changed.
