Single-Extrusion Co-Extrusion Multi-Layer Extrusion Fluoro Polymer Extrusion Special Applications Colour Changing Systems Bypasses Tools
::: Bypasses :::
Automatic discharge valves with alternatively hydraulic pneumatic or manual actuation. Installed as a separate unit between extruder and head they serve for the diversion of the melt stream to the open and simultaneously for the pressure release inside the crosshead.

Besides the drive modus differences between the various types are made also with regard to the diameter of the flow channel which is determined by the head sizes and by the design of the bleeding bore - axial or diagonal - subject to the bypass positioning.
