Loss-in-Weight Hoppers

The LIW Loss-in-Weight hopper is suited to all extrusion processes.

  • Automate material usage control for all extrusion processes
  • Return on investment within 6 months
  • Raw material savings up to 10%

Loss-in-Weight Hopper for Extrusion

Loss in Weight Control

  • Comprehensive loss-in-weight control, monitoring live consumption rate to an extruder and updating process rate every second.
  • The LIW hopper is suspended on a pair of highly accurate load cells. 
  • Sized according to throughput.
  • Throughput of line is fully automatic and requires no user intervention.

Maguire + Syncro Syntrol Control

  • Maguire + Syncro specialist extrusion control for every type of extrusion process.
  • Syntrol touchscreen allows quick and easy setup of extrusion process. 
  • Easily set process parameters like gram/meter, micron and layer ratios.

Key Benefits of Extrusion Control

  • Overall raw material savings of up to 10% compared to manual regulation.
  • Reduced start-up material wastage & changeover scrap.
  • Achieve faster startup times.
  • Automatically regulate extruder and haul-off speeds to always be on target.
  • Eliminate process variations due to screen pack, voltage fluctuations and MFI differences.
  • Document clearly material usage and process parameters for quality, process and cost control.
  • Return on investment within 6 months. 
  • Fast payback by reduced material usage, production scrap, manual intervention and increased productivity.
  • Optimize process from constant extrusion control.

Simple Operation

Range of Material

  • Suited to every application of free-flowing material, pellets, granules or powder.

Rapid Access

  • Magnetic retainers on the hopper enclosure allow quick access to the LIW hopper.

Audible and Visual Alarms

  • Alarms are activated is system is not operating withing required process conditions.

Faster-Start up Time

  • Switch from manual start-up to automatic and set required output.
  • No further operator involvement.

Quick Material Release

  • Optional compact drain can be mounted directly below the LIW hopper.
  • Rapid draining of materials.

Solutions for Extrusion Processes

Solutions for Extrusion Processes

  • Suited to all continuous extrusion processes for mono and co-extrusion processes.
  • Applications include cable, cast film, blown film, sheet, pipe, tube & profile extrusion.

Maguire+Syncro Control Flexibility

  • Detailed control of all material settings, layer ratio control, & extrusion control.
  • Controller allows effective control for mono and co-ex processes, managed from 1 HMI.

Expandable & Modular

  • The LIW control is expandable and can be simply integrated with further downstream controls for automatic gauging and process control
  • LIW Hopper extrusion control module can easily be retrofitted with other modular components from Maguire + Syncro including air rings, IBC control, Gauging, and in-line recycling. 

Adding Masterbatch and Additives

Options for incorporating MGF Gravimetric Feeder into Maguire + Syncro control for accurate dosing of masterbatch and additive. 

  • The Maguire MGF series can be used for all extrusion applications.
  • Fit easy, cost effective control for an additive or masterbatch. 
  • Plugs in and controls directly from Maguire +Syncro control box
  • Feeder automatically re-calibrates to new color, so no additional setup required.
  • Feeder automatically doses according to extrusion throughput reference entered into control.
  • MGF follows complete process data from LIW live. Loss in weight updates process consumption every second.
