OEM Screen Changers for Polymer Melt Filtration

OEM Screen Changers for Polymer Melt Filtration are used as part of a new extrusion lines. These screen changers are purchased by leading extrusion equipment manufacturers for their good performance and design.

OEM Screen Changers for Polymer Melt Filtration Design elements:
Co-ordination of screw length, close to the breaker plate
Exchange of information regarding mating pieces (extruder & die/melt pump) to ensure proper fit
Minimize overall length of adapters to optimize polymer flow.

Advantages of a Screw Tip Extension:
Screen changers can be installed in an extrusion line with or without a screw tip extension.
The drawings below illustrate both solutions.
If there is no screw tip extension, a reduced flow canal is normally used to minimize the polymer inventory as much as possible.
Polymer degradation is eliminated as a result of uniform velocity across the section of the material between the tip of the extruder screw and the filtration screen
The color change-over time period is reduced due to low polymer inventory between the tip of the extruder screw and the filtration screen.

We can offer the most typical ways in which our OEM screen changers for polymer melt filtration can be retro-fitted into existing lines. We coordinate the mechanical and electrical aspects of the project to ensure that the screen changer is a fully integrated component of the extrusion line.
