• Slip Heating in Die Drool 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2014-05-14)
      When molten plastic is extruded from a die, it can collect on the open die face. Called die drool, this phenomenon costs plastics manufacturers by requiring shutdown for die cleaning. This has been attributed to cohesive ...
    • Slip Heating in Die Drool with Viscous Dissipation 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2014-10-06)
      Plastics can build-up on the die lip during extrusion. This phenomenon is called die drool and can be costly for plastics producers, requiring periodic shutdowns for die cleaning. Die drool has been attributed to the ...
    • Wall Slip Heating 

      Gilbert, Peter H.; Giacomin, A. Jeffrey (2015-01-05)
      When molten plastic is extruded, the upper limiting throughput is often dictated by fine irregular distortions of the extrudate surface. Called sharkskin melt fracture, plastics engineers spike plastics formulations with ...
