Abstract

Injection press has feed, compression, decompression, recompression and transport zones. The material is reheated while passing through, but is neither heated nor cooled in the feed and compression zones. It is reheated to pref. below the gelling or m.p. in the decompression zone, and at least up to the gelling temp. or m.p. in the recompression and transfer zones.
