GUIDELINES FOR USING CESA CLEAN ADDITIVES • Cesa Clean works best when molded maintaining normal (injection) pressure/shear • For best results, Avient recommends a “Running Color Change” which eliminates breaks in the molding cycle • Since the Cesa Clean concentrate will expand, it is recommended to reduce the shot size by 20% • It is designed for use at a let-down ratio (LDR) of 3.0% or (33:1); however, use rate can vary depending on the severity of the contamination but typically is 2.0–4.0% (a use rate higher than 6.0% may not have any positive affect on the cleaning performance) • Using Cesa Clean as a routine part of your color change rotation will allow faster changes and consume a minimal amount of raw material - Note: If the manifold is not cleaned routinely, this process may be more time consuming and additional material will be required • It is best to process at your normal polymer processing temperatures - For best performance, stock temperature should be at least 400°F - If 400°F is achieved during the purging process, no additional activation will occur during the reprocessing of regrind - All parts produced during the “Running Purge Cycle” should be captured as regrind, resulting in a scrap-free color change - If using sequential gates, open and close all gates at the same time while purging the tool - If contamination appears to be coming from one gate, open and close first, and for an extended period of time, to force more material through this location - When cleaning in this manner, pay close attention to shot size - Parts containing the previous or new color plus any Cesa Clean can be used as regrind INTRODUCING CESA CLEAN TO YOUR PROCESS Hand Blend • Hand weigh enough of the Cesa Clean and natural resin mix to equate to 3–5 times the barrel capacity • Use rate should be 3.0% or 33:1 for routine cleaning • For difficult-to-clean tooling, or tooling which is not routinely cleaned, start at 4.0% or 25:1 • Note: Do not attempt to vacuum load more than 15 feet from source as stratification/separation may occur Volumetric Feeder • Calibrate feeder to dispense 3.0% or 33:1 for routine cleaning • For difficult-to-clean tooling, or tooling which is not routinely cleaned, start at 4.0% or 25:1 • This style of feeder is highly recommended for at-the-throat metering of Cesa Clean Blending Units Most blenders have an extra bin for an additive • Fill the additive bin with Cesa Clean • Set blender to introduce the Cesa Clean at 2.0 to 4.0% • Note: Do not air convey any further than 15 feet as Cesa Clean has a high density and may separate from the mix. 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.
