It then freezes after pack and hold and acts as a plug.
However, a gate needs to be large enough to provide good packing.
This type of packing is what gives the part a good surface finish.

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.

Pressure - This part of the equation is usually caused by over stacking hot garments at the oven or packing them immediately into boxes.
Certain things cannot be controlled by the printer: • The dye in the shirt • The humidity in the air and shirt Things that can be controlled are: • The type of ink – cotton white for cotton, non-ghosting bleed resistant for polyester • The amount of heat used on the garment—cure at the recommended temp, not over • Stack in separate piles to allow cooling—fold in dozens separately, wait to pack Be aware of at-risk colors; brown, tan and beige are the most sensitive to possible ghosting. www.avient.com Copyright © 2020, Avient Corporation.

FlexCart Nano is the ideal metering system for smaller throughputs and uses a standard 1kg PlanetPak™ container as the delivery pack.
This includes a single point level monitoring system to indicate when a delivery pack change is required.

Since the FlexCart Micro has a smaller footprint for use in operations where space is limited, the metering system uses the smaller 10L (LN) polymer delivery pack.
The FlexCart Micro unit, due to its smaller footprint and reduced throughput range, is designed to work with the LN molded polymer containers—specifically the 10-liter pack.
