Abstract
A synthetic-resin article is molded by plastifying a virgin granulate into a fluent stream and plastifying a recycle granulate into another fluent stream. The recycle stream is then filtered while still plastified to removing particulate impurities from it. Then the filtered recycle stream while still plastified is combined with the virgin stream to form a combined stream and the combined stream is fed into a mold. The stream is mechanically filtered.
