The slightly different process
The task of the single or twin screw extruder in the extrusion process is to melt, homogenize, compound and degas the material. When the necessary pressure needed by the attached extrusion tools like nozzles, dies and pelletizers, is too high for an extruder or compounding line, then single screw discharge extruders or gear pumps are used to build-up the needed pressure.
In compounding or extrusion lines, which are primarily designed for high through puts, the polymer is very often stressed up to the breaking point. Unnecessary shearing of the polymer caused by the pressure build-up device damages the product. Another determining factor concerning the product quality is the conveying continuity of the device, building the needed pressure.
Our solution in a new dimension
With the new Xtreamor melt pump, developed by Henschel, the pressure build-up happens by specially designed and adjusted to the melt properties, twin screws. The Xtreamor works with the lowest possible pre pressure due to the design-conditioned forced conveying. So the compounder respectively the extruder is relieved of a lot of workload.
