"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 final shape 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 %22fountain flow%22. The fluidity of polymers is affected by many parameters inc. mold design. Evaluation of set of data obtained by experiments where the testing conditions were widely changed shows that quality of cavity surface markedly affects on the length of flow." .
