Extrusion die extrusion process.
General according to the type of processing of polymer extrusion process and the shape of the products or semi-finished products, selected extruder, the nose and mouth mold, and finalize the design and drawing the corresponding auxiliary device, and then determine the extrusion processing conditions such as screw speed, head pressure, material temperature, and finalize the design temperature, pulling speed, etc.In the process of extrusion, materials are generally plasticized, but the method of stereotyping is different.For example, the extruded plastic often needs to be cooled and solidified, and the semi-finished product of extruded rubber needs further vulcanization.Different products can be obtained by different extrusion equipment and process.
The aggregates are mixed with various additives to melt in the extruder and further mixed.Through orifice
Molds, forming multiple strips, then cut into granules.Cut off the hot and cold cuts.The former strip is separated from the mouth mold, one side.
With air or water, cut off with a rotary knife immediately.The latter is to cool the strip, and then into the granulator to cut the grain.
Melt spinning of some of the most viscous resin in melt spinning, commonly used extruder to melt materials.The melted material goes directly through the filter into the spinneret, or into the spinneret with a spinneret pump.
