MELT PUMPS FOR PRODUCING SYNTHETIC GRANULES, EXTRUDED PROFILES OR MOLDED PARTS

摘要

Melt pumps for producing synthetic granules, extruded profiles or molded parts are disclosed. One disclosed example apparatus includes a worm machine to move synthetic melt, a tool for producing granules, an extruded profile or a molded part, and a melt pump separate from the worm machine, where the melt pump is to press synthetic melt through the tool, and where the worm machine transfers the synthetic melt to the melt pump at a lower pressure than the synthetic melt provided by the melt pump to the tool.

主权项

1. A device for manufacturing synthetic granules, extruded profiles or molded parts comprising:
a worm machine for producing synthetic melt; and a melt pump to build up pressure, the melt pump to press the synthetic melt through a tool, wherein the tool is for creating the granules, the extruded profile or the molded part, wherein the melt pump is separate from the worm machine and has a separate drive, and wherein transfer of the synthetic melt from the worm machine to the melt pump occurs at atmospheric pressure or substantially atmospheric pressure.
