Aquamix additives are fully compatible and easily compounded with base polymers.

KEY CHARACTERISTICS The primary features and benefits of Gravi-Tech formulations are: • Customized density, offering a wide range of specific gravities from 1.5 to 11 gm/cm3 • Broad modulus range, from very flexible to very rigid grades • Corrosion resistance, withstanding oxidation for long-term use and benefit • Chemical resistance, withstanding fuels, oils and other harsh chemicals Additional features include: • Design flexibility and processing ease • Good impact strength • Elevated heat deflection temperature 6 Gravi-Tech Design Guide 7 CHAPTER 2 | PROCESS SETTINGS Density Modified Formulations Gravi-Tech™ polymer-metal composites are high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals. This adhesive is not very chemically resistant, and has lower strength properties. 14 Gravi-Tech CHAPTER 4 | MOLD DESIGN GUIDELINES COLD RUNNER LAYOUTS Herringbone (Fishbone) Runner This type of runner has an unbalanced fill, which can be artificially balanced by adjusting runner sizes. Design Guide 33 Mold damages Loss of clamp force Barrel malfunction Melt temperature too Transfer position too low Excessive pack pressure Excessive back pressure Repair mold damage Clean parting line Reduce pinch-off land Increase clamp force Dry material Reduce melt temperature Reduce mold Reduce hold pressure Increase transfer Flash • Excess material commonly found at parting lines or mold features Root cause: Too much plastic or mold damage. 34 Gravi-Tech Design of gate too small or in wrong location Machine not providing Heater overriding Viscosity too low Injection velocity too high Melt temperature Remove sharp corners Change gate type Move gate to a position where the melt stream will impinge upon a mold feature Dry material Reduce injection velocity Increase melt Jetting Root cause: Injection speed is too high for the viscosity of the material Design Guide 35 Finish too rough Screw configuration Overworking material Non-compatible additive Melt temperature too Remove sharp corners Use smaller screw/barrel Check melt uniformity Check L/D ratio Check additive compatibility Reduce screw speed Reduce residence time Plate-Out • Build-up or deposit on mold surface Root cause: One component of the material is not totally compatible. 36 Gravi-Tech Shut-off partially turned Screw problems Barrel heater problems Material too dry Under-packing Not enough pack pressure Transfer position too high Make sure gate is not blocked Insure runner shut-off is not turned Check venting Change gating location Add flow leader Insure cushion position Make sure screw is trans- ferring at a correct Change screw/barrel Make sure material was dried at proper settings Increase melt Increase mold Decrease transfer Short Shot • Not enough material is being injected into the mold to fill out all of the cavities Root cause: Not enough plastic is getting into the cavity.
