Abstract
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.
Claims19
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.
A melt pump for building up pressure at a fluid medium, the melt pump for pressing the medium through a tool, comprising:
- a compressor that comprises an inlet and an outlet opening;
- and
- at least two worm conveyors disposed in a common housing, wherein worm flights provided on the worm conveyors are configured in such a manner that a force feed of the medium occurs and wherein the worm conveyors are drivable by their own drive
An apparatus comprising:
- a worm machine to move synthetic melt;
- a tool for producing one or more of granules, an extruded profile or a molded part;
- and
- a melt pump separate from the worm machine, the melt pump to press synthetic melt through the tool, wherein the worm machine provides the synthetic melt to the melt pump at a lower pressure than the synthetic melt provided by the melt pump to the tool.
