Method of processing molten plastic materials.

摘要

Molten plastic material is transferred from a source (10) of molten plastic material to a nozzle (16) for supplying a mold (11) for the formation of molded plastic articles along a transfer path (14), which subjects the molten plastic material to shear heating along the transfer path (14) with the creation of a shear heating history. The shear heating history of the molten plastic material is substantially equalized by mixing the material at least once in the transfer path (14). The heating history of the molten plastic material is also equalized by mixing the material while it is in the source.
