Multi-Layer Pipe Making Machine

IMPORTANT POINTS BEFORE STARTING CO-EXTRUSION:

-It is very important to select polymers that meet a host of performance requirements in the finished extrusion and will also bond to form a strong structure.

-It is necessary to use layers and additional extruders, if the polymers selected for the co-extrusion do not provide adequate bonding strength.

NOTE: All plastic cannot be extruded because some polymers will not adhere, but introducing a conductive middle layer can often solve this problem.   

TYPICAL CO-EXTRUSION EXAMPLES:

Just keep in mind that most extrusion processes use co-extrusion in some form to produce products that cannot be made with just one resin source.

- In pvc pipe productions, co-extrusion is used to apply a stripe to one or more of the pipe sides, providing multi-layer pipes that may have one color material on the inside and another color or material on the outside.
