LineMaster
TM
Extrusion Control
LineMaster
TM
is for all continuous extrusion processes including film, sheet, pipe, coating and
lamination, wire and cable and compounding. LineMaster’s flexible design provides several
measurements and control options, and includes an integrated system for combining gain-in-
weight dosing control with loss-in-weight extrusion control. The system is an easy to use low cost
alternative to competitive loss-in-weight systems without compromising performance and control.
Benefits of LineMaster

Improved product quality through permanent and consistent control

Reduced material costs through improved yield

Automatic regulation of extruder output

Increased line productivity with fast start-up and reduced production scrap

Quick product changeover

Alarms and user security
WEIGHT MEASUREMENT OPTIONS
Basic Extrusion Control with Maguire
®
Blender
Extrusion line throughput may be determined by monitoring material consumption as recorded by
the batch weighing process of the blender divided by the time the batch takes to be consumed.
Throughput is determined by the blender controller when 5 consecutive batches have shown a
steady throughput rate. If 2 batches show consecutive errors an adjustment is made to maintain
the desired throughput rate.
Basic Extrusion Control provides a very cost effective solution for long product runs on mono-layer
lines. The blender must be throat mounted. Basic Extrusion Control is simple, has less mechanical
parts and requires low maintenance.
Basic Extrusion Control Limitations:

Frequent job and/or material changes

Blender not mounted on the extruder throat (surge hoppers / floor stands)

Co-extrusion lines running low throughputs

Lines with frequent ramp up / ramp down requirements

Restricted loading systems or poor flowing materials
