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.

Maguire Control Options

XC-1 & XC-2 Software Control	– Standard Control system for XC-1 and XC-2 Mono Extrusion Applications – Either switch to lock mode directly and set target from controller – Or ramp up manually then switch to lock mode to fine tune setting – Compact and simple control
Take-off Drive: Potentiometer (T) Extruder Drive: Potentiometer (X)	– Digital Pot Wheel – Lock / Manual Mode Switch – Voltage Display 0.00v to 9.99v

LIW Options

Option	Model	Description
Surge Hopper	LIW-05W, LIW-10W, LIW-25W, LIW-40W	Quick filling of LIW hopper for fast process turnaround
Drain Ports	LIW-05W, LIW-10W, LIW-25W, LIW-40W	Mounted below the LIW hopper for quick material evacuation and simple cleaing and material changes
MSF Starve Feeders	LIW-05W, LIW-10W, LIW-25W, LIW-40W	Regulates the weight per hour of material supplied to ther line. Prevents the twin-screw extruder from being flooded with material
FMC Flow Moderator Cones	LIW-05W, LIW-10W, LIW-25W, LIW-40W	For use with free-flowing powders such as PVC. Ensures consistent flow from LIW hopper into extruder
