Effect of Leakage Flow on Processing of Resinous Mixtures in the Pressure Zone of an Extruder

It is noted that results disagreeing with reality are obtained when familiar mathematical models describing the effect of leakage flow on the processing of a resinous mixture in an extruder channel are used. The material balance in the pressure zone of the extruder, and the influence exerted by leakage flow on the processing of the mixture are examined.
