The invention describes an advanced mixing and metering technology with online analytics for a supply of formulated liquid thermosetting resins into an open or closed mold. The application addresses where a precise control of the composition of formulated components is required. Composite structures used in primary and secondary structural aerospace applications manufactured in Infusion or RTM processes are possible examples.

Methods, apparatuses and systems are disclosed including a method of filling a container with substantially only a liquid. The method can include the removal of a gas from the container prior to, during or after the filling of the container with the liquid. According to one embodiment, the container includes an inner liner and a lid. The method includes providing a volume defined by at least the inner liner and the lid of the container. In such embodiment, the liquid can initially be contained within a first portion of the volume and a remaining portion of the volume can contain a gas. The method can include removing substantially all the gas from the volume via one or more ports that communicate with the volume while retaining substantially only the liquid within the volume.

This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).
