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.
Smart Control
- LineMaster Extrusion Control 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.
- 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 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 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.
