Multi-gate reaction injection assembly for use with a closed mold for mixing and setting iso and poly fluid based polymers withoneor more aggregate filler material

摘要

The present invention discloses a multi-gate assembly for creating a composite article, typically including a mold including a closed interior cavity, a first mixing gate in communication with the mold, and at least one iso-based polymer material and at least one poly-based polymer material concurrently fed into the first mixing gate. At least one filler material is fed into a second gate in communication with the first gate, and a composite associated with the iso/poly/filler materials is communicated into the cavity for formation into a three-dimensional article.
