A Closer Look at the Pipe Extrusion Die Head
The extrusion die head is one of the key components responsible for shaping a plastic pipe.
After the plastic melt enters the die head, its internal flow channels distribute the material around the core. The gap between the die and mandrel then forms a continuous tubular profile for subsequent vacuum sizing and cooling.
The image highlights the heating and temperature-control connections, flanged inlet, and bolted assembly. The die-head configuration should be matched to the material, pipe diameter, wall thickness, layer structure, and required output.
