Abstract

Press has feed, compression, decompression, recompression, and transport zones. The material is neither heated nor cooled on the feed or compressing zones, but is reheated to a temp. well below the setting point in the decompression, zone, and is heated to slightly below the setting temp. in the recompression and transfer zones. Setting occurs in the mould.
