  • Cure Feeder Problems in Twin-Screw Compounding

    Imagine, for example, that a polymer feeder momentarily feeds above setpoint at the same time that a filler feeder is feeding below setpoint. These two materials fall together into the twin-screw extruder and are conveyed downstream as a “batch” that is below the target filler loading. Now imagine that after some period of time, these same two feeders swing to the opposite extremes

  • In the Mix: Continuous Compounding Using Twin-Screw

    Because twin-screw compounders are not flood fed, the output rate is determined by the feeders, and screw speed is used to optimize the compounding efficiency of the process. The pressure gradient in a twin-screw extruder is controlled and kept at zero for much of the process (Figure 7). This has substantial ramifications with regard to sequential feeding and to direct extrusion of a product
