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
• 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
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.
