METHOD AND APPARATUS FOR ENHANCED MINIMAL SHEAR MOLDING UTILIZING EXTRUSIONAL, PELLETIZATION, AND MELT RHEOLOGICAL CONTROL OF PELLETS AND MICROPELLETS AND MOLDED OBJECTS MADE THEREFROM |
摘要 |
The various embodiments of the present invention relate to methods for enhancement of minimal shear molding processes. This can be accomplished using pellets and/or micropellets, along with optional powders. The pellets and/or micropellets can be produced through controlled extrusional and pelletization processes in combination with nonpowder melt flow rheology that incorporates reduced molding temperature, reduced cure time, reduced rotation axis ratios, and/or reduced rotation rates. Molding can be uniaxial, biaxial, or multiaxial, and rotational, oscillatory, or both. The molded items produced can have a single layer or multiple layers, and can be produced in one or more molding sequences using similar or different chemical compositions. |
