Extruder cuts downtime with purging compound

Amhill Enterprises, Ltd. (Mississauga, ON) has reported a 50% reduction of downtime during color changes in an extrusion process as a result of switching purging compounds, according to recent case study. The downtime reduction was realized in the manufacturing of disposable polystyrene plastic lids, which Amhill produces in a variety of colors. The company reduced downtime after a color change from one hour to 30 minutes by switching to a thermoplastic purging compound, Dyna-Purge X. Amhill had been using a liquid purging agent during color changes from dark to natural or white, and during low amps in an extruder when plastic lumps would stick in the screw (bridging). The liquid agent required mixing and activation steps, whereas the new agent eliminated these steps.
