Extrusion Feed Zone at Isaac Randy blog

Extrusion Feed Zone. Compression zone — depth gets shallower, as if the walls were closing in on the plastic, and that builds pressure preventing the air between the particles from continuing down the barrel. Feed hopper, with which the particulate solids are put into the extruder. The screw starts with a feed zone: The extruder screw is designed with three main zones or sections: The temperature in the first extruder zone is critical for good feed characteristics. Constant depth, takes up 15 to 30% of length. This zone feeds the resin into the extruder, and the channel depth is usually the same throughout the zone. Extrusion is one among the most commercially successful technology, escalating its demand in the diverse field of the food. Most of the polymer is melted in this section, and the channel depth gets progressively. If the zone 1 temperature is too high, premature melting may. Feed, compression and metering sections. In the middle is the compression zone, walls close in on the melt/pellet mix, drive air backward and make up for slipping and rolling of pellets in the feed zone. Most screws have these three zones: Melting zone (also called the transition or compression zone): Feed zone — depth is constant and deep enough to take in the plastic particles.
