Mold Design Recommendations Gates 1. If material is not in the recommended moisture percentage for molding, dry material until it is in the acceptable range for molding. If material is not in the recommended moisture percentage for molding, dry material until it is in the acceptable range for molding.

Mold Design Recommendations Gates 1. Hot runner molds are acceptable and should be sized by the manufacturer. Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression • Verify material has been dried at proper conditions Incorrect nozzle • Use reverse taper tip Weld Lines Melt front temperatures are too low • Increase pack and hold pressure • Increase melt temperature • Increase injection rate • Increase mold temperature Mold design • 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 Process related • Increase cooling time • Increase melt temperature • Increase pack pressure • Increase pack time • Decrease mold temperature Mold design • Non-uniform mold cooling Part design • Non-uniform wall thickness Thermolator incorrect temperature • Check settings • Inspect thermocouple Processing Guide 7 Troubleshooting Recommendations Problem Cause Solution Sticking in Mold Overfilled cavity • Decrease injection rate and pressure • Decrease pack and hold pressure • Adjust transfer position • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease cooling time Mold design • Increase draft angle• Polish cores in direction of ejection Part is too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time 1.844.4AVIENT www.avient.com Copyright © 2024, Avient Corporation.

Achieve complex designs without expensive tooling – Gravi-Tech material can be injection molded into unique part shapes utilizing lower cost molds made of P20 or H13 steel. Add weight while simplifying your processing steps – Simplify your manufacturing process by injection molding a weighted, finished part in one step rather than adding a metal weight. Reduce the number of parts – By injection molding Gravi-Tech material, you will no longer need to assemble multiple parts to achieve added weight.

The two primary over-molding processes are Multiple Material Molding and Insert Molding. Multiple Material Molding Multiple Material Molding is also sometimes called multicolor or two-shot injection molding. Insert Molding uses conventional injection molding equipment.

KEY CHARACTERISTICS • Patented next-gen formulation that can preserve visual clarity and aesthetics in applications using recycled content • Reduces bacterial, mold, and fungal growth on the surface and through the thickness of the plastic part • Helps reduce odor, staining, discoloration, and loss of mechanical properties • Available for various processes including extrusion, injection molding, blow molding, rotational molding, and thermoforming MARKETS & APPLICATIONS These antimicrobial additives are well-suited for clear polycarbonate or plexiglass applications using recycled resin including: • Electronics • Packaging • Consumer goods • Protective shields and sneeze guards • Plexiglass windows or panels • Clear phone or tablet cases • Modular office construction • Point-of-purchase screens • Touchscreen information kiosks • Transportation infotainment screens 1.844.4AVIENT www.avient.com Copyright © 2025, Avient Corporation.
