Improve performance, enhance your capability
• Meet higher performance requirements
with thermoplastic materials
• Reduce part weight
• Achieve rapid cycle times
• Differentiate with expanded manufacturing and
product performance capabilities
Dramatically increasing impact resistance and
stiffness of molded components—without adding
significant weight—means that OEMs can meet
increasingly demanding application requirements.

Constituents added to resins, such
as colorants and additives, must be adapted to
obtain a final article compliant with prescribed
standards such as EN13432 for Packaging
Applications and EN17033 for Agriculture Mulch
Films.

Improves traceability as the color indicates the additive has also
been added.

GETTING STARTED
TIMING IS THE KEY TO A RUNNING
COLOR CHANGE
Hand Blend
• Have the purge blend ready to load
• If hopper contains a mixture of resin, color and/
or regrind, it should be run dry or drained before
beginning the color change, keeping the screw
full so press cycle continues
• Run the main resin hopper dry or shut off hopper
to hand feed at the throat
• Once press is clean, slide hopper in place
and proceed with next color-resin blend
• The next color can be added while Cesa Clean is
still in the barrel
• When splay is no longer visible in parts, reset shot
size, parts should be ready to pack
(Single) Volumetric/Gravimetric Metering Unit
at the Throat
• Empty and clean feeder while press continues
to run
• Add Cesa Clean to the feeder color hopper and
calibrate to a 3.0% use rate
• When press is clean, start next color
• When splay is no longer visible in parts, reset shot
size, parts should be ready to pack
• Note: If an open/unused secondary feeder is
installed, use it for the Cesa Clean concentrate
Central Blending Unit
• Thoroughly clean unit while continuing to mold
parts, keeping a resin feed to the press
• Using a clean open hopper or regrind hopper, add
the Cesa Clean concentrate
• Set blender for additive/color to 3.0%
• Once press is clean, drain hopper and/or central
blending unit while continuing to mold parts
• Begin new color and continue to mold parts
• When splay is no longer visible in parts, reset shot
size, parts should be ready to pack
Process Adjustments That Can Help
• Increase back pressure
• Increase screw speed
• Increase injection speed (in some tools maximum
injection speed can facilitate cleaning)
• Reduce mold close time (faster cycle)
• Always remember a stock temperature of 400°F
is essential
When press and tool are clean, return all settings to
standard production process profile.

Long fibre reinforced
materials have an added degree of modelling complexity
due to the need to capture the effects of bundling, fibre
entanglement and weld lines.

Part walls need to remain parallel when
adding draft.
One thing to avoid in adding draft
are large variations in wall thickness .
The water line
connections to the mold should be kept to as
few as possible, and jumpers should be avoided
unless permanent jumpers can be added .

Patterson added, “Our Color, Additives and Inks segment also delivered record operating
income of $58 million during the fourth quarter.
Patterson added, “We will provide more details on our upcoming webcast, but our headline
projection for 2021 is that we expect revenue growth of approximately 8% pro forma will drive
adjusted EPS expansion from $1.93 to $2.40 - an increase of 24%.”
