Screen changers for polymer melt filtration

Screen changers for polymer melt filtration have an outstanding advantages, it is no downtime, such as no moving parts, no hot breaker plates to handle, no wear, no leaks, etc. Advantages and specifications are also available.

Screen changers for polymer melt filtration features:
Constant extruder head pressure is maintained indefinitely: uniform melt temperature; steady pumping rates.
Precision gauge control: scrap & reject rates significantly reduced.
Color changes: no extra steps are needed to handle color changes. By the time the screw and barrel are purged, the screen changer body is free of any color residue.
Polymers: screen changer can handle all commonly used families of thermoplastics, including flexible PVC and most engineering resins.

Screen changers for polymer melt filtration technical specifications:
Finite Element Analysis used throughout to optimize polymer flow.
Adapters custom engineered to fit any make extruder.
Compact size can easily be retro-fitted into most lines without any modification to existing equipment.
Screen changers for polymer melt filtration for both the Metric and English (Inch) environments

Screen changers for polymer melt filtration advantages:
No downtime:
No Moving Parts:
The force of the extruder head pressure is used to move the screen. No driving mechanism (air cylinder or hydraulic power package) to maintain.
No Hot Breaker Plates to handle:
No screen packs to change. The screen belt moves automatically through the screen changer flow canal.
No operator attention required for day-to-day operation:
The controls can be interlocked to follow the status of the extruder’s functioning.
No wear, no leaks:
No metal-to-metal seals to wear out. Leak proof polymer seals maintained indefinitely by the continuously circulating cold water.
