Typical readouts include melt pressure, melt temperature, motor amperage, vacuum level, and material viscosity. The selection of a feeding system for a twin-screw compounding extruder is extremely important. Multistage venting and/or foaming processes might even require tandem extrusion systems that link together multiple extruders to string together and resolve conflicting unit operations, such as high-intensity mixing combined with using a second extruder as a heat exchanger to cool the melt. Guest Editors: Feng Zhang and Michael A. Repka. Technology and Principles, 2nd ed. A top and end view of the calender gap is presented in Fig. B&P Littleford's Specialty series extruders allow for excellent mixing, optimal degassing, and reliable cooling with high throughput.
