SHANGHAI – At Chinaplas 2014, PolyOne ColorMatrix, the global leader in liquid color and additives for plastics, will launch its newest liquid color system, which gives manufacturers greater control of their color development and supply chain. By combining cloud-based color creation software, unique liquid color technology, and a global network of ColorMatrix facilities, the new platform helps customers to create and order custom colorants quickly, reducing development and supply turnaround time from weeks to days – or even hours. Ultra-fast Visualization and Choice: Infinite color options via a cloud-based color library with up-to-the-minute performance, regulatory, and pricing information at the start of the color development process.

Note to converters: This product is compatible solely with transparent bottles produced in a two- stage injection stretch blow molding process. LD R (% Impact of 5 Melt Heat Histories on Preform Color Reference ColorMatrix AAzure Reduction in AA Level 35% 55% 70% ColorMatrix AAzure allows for further optimization of the polymer weight distribution during the bottle blowing process, which improves mechanical strength and bottle quality. They are metered into the PET stream just above the feed throat of the injection molding machine or extruder, using a Avient supplied ColorMatrix liquid metering system.

标题:Avient’s PCR Color Prediction Service helped achieve color consistency in L’Oréal PCR packaging worldwide for its Redken line of hair care products. Having identified optimized colorants for the packaging of the Redken line worldwide, Avient’s PCR Color Prediction Service helped L’Oréal simplify overall color development with recycled resin. This means fewer color iterations, fewer color trials, and fewer plastic bottles traveling from one zone to the other.

MOLD DESIGN RECOMMENDATIONS Gates • Many different types of gates can be used such as pin, fan, tunnel, tab and edge gates. Hot runner molds are acceptable and should be sized by the manufacturer. PROBLEM CAUSE SOLUTION Incomplete Fill Melt and/or mold temperature too cold Shot Size • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection speed • Increase pack and hold pressure • Increase nozzle tip diameter • Check thermocouples and heater bands • Enlarge or widen vents and increase number of vents • Check that vents are unplugged • Check that gates are unplugged • Enlarge gates and/or runners • Perform short shots to determine fill pattern and verify proper vent location • Increase wall thickness to move gas trap to parting line • Increase cushion Brittleness Melt temperature too low Degraded/Overheated material Gate location and/or size • Increase melt temperature • Increase injection speed • Measure melt temperature with pyrometer • Decrease melt temperature • Decrease back pressure • Use smaller barrel/excessive residence time • Relocate gate to nonstress area • Increase gate size to allow higher flow speed and lower molded-in stress Fibers on Surface (Splay) Melt temperature too low Insufficient packing • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase pack and hold pressure, and time Sink Marks Part geometry too thick Melt temperature too hot Insufficient material volume • Reduce wall thickness • Reduce rib thickness • Decrease nozzle and barrel temperatures • Increase shot size • Increase injection rate • Increase packing pressure Flash Injection pressure too high Excess material volume Melt and/or mold temperature too hot • Decrease injection pressure • Increase clamp pressure • Decrease injection speed • Increase transfer position • Decrease pack pressure • Decrease shot size • Decrease injection speed • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease screw speed TROUBLESHOOTING RECOMMENDATIONS PROBLEM CAUSE SOLUTION Excessive Shrink Too much orientation • Increase packing time and pressure • Increase hold pressure • Decrease melt temperature • Decrease mold temperature • Decrease injection speed • Decrease screw rpm • Increase venting • Increase cooling time Not Enough Shrink Too little orientation • Decrease packing pressure and time • Decrease hold pressure • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase screw rpm • Decrease cooling time Burning Melt and/or mold temperature too hot Mold design Moisture • Decrease nozzle and barrel temperatures • Decrease mold temperature • Clean, widen and increase number of vents • Increase gate size or number of gates • Verify material is dried at proper conditions Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression • Verify material has been dried at proper conditions Weld Lines Melt front temperatures too low • Increase pack and hold pressure • Increase melt temperature • Increase vent width and locations • Increase injection speed • Decrease injection speed • Increase gate size • Perform short shots to determine fill pattern and verify proper vent location • Add vents and/or false ejector pin • Move gate location Warp Excessive orientation • Increase cooling time • Increase melt temperature • Decrease injection pressure and injection speed • Increase number of gates Sticking in Mold Cavities are overpacked Part is too hot • Decrease injection speed and pressure • Decrease pack and hold pressure • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time • Increase draft angle • Decrease nozzle and barrel temperatures • Decrease mold temperature TROUBLESHOOTING RECOMMENDATIONS www.avient.com Copyright © 2020, Avient Corporation.
