Abstract
A in-line extrusion die is disclosed including a cylindrical mandrel and a die bushing surrounding the mandrel and forming therebetween a passageway leading to an extrusion orifice. The mandrel is mounted to one side of a spider plate and a tailcone is attached to the other side thereof. A die body containing a melt chamber surrounds the tailcone and forms a conical passageway therebetween. A thermocouple is mounted at the apex end of the tailcone for measuring the temperature of the melt as the melt flows from the melt chamber and through the conical passageway. The spider plate contains a plurality of openings which communicate with both passageways and allow the melt to pass through the plate and thence to the extrusion orifice.
