Modular Control System for Blown Film

摘要

During October's l< 2019 show in Dusseldorf,Maguire Products displayed a new control system for blown film that can be deployed in a new production line as part of a total system providing single-point supervision of all line components,or retrofitted to an existing line to increase productivity and reduce material cost.For a new blown film line,there are three basic components at the heart of the Maguire + Syncro extrusion control system: the Maguire WXB Weigh Extrusion Blender,which incorporates a gain-in-weight weigh bin and a loss-in-weight mix chamber; the Maguire 4088 controller,which controls loading,blending,and metering of raw material to the extrusion process; and the Syncro controller,which uses the material-consumption data from the 4088 controller to control line speed.Modes of extrusion control available with the Maguire + Syncro system include Ib/hr or kg/hr; weight per length of extrudate; and product thickness in microns.controls for all types of extrusion.If the blown film processor seeks single-point control of the entire production line,Syncro has developed the Syntrol supervisory system,which allows multiple line controls to be visualized and synchronized from one touchscreen.These controls include those for extruder temperature and pressure,air ring,IBC,thickness gauge,cage,and haul-off.
