Abstract
A molding apparatus for molding an optical article has a reactor vessel having an interior cavity configured to receive a quantity of a flowable forming material, a mold assembly defining a mold cavity therein, a diaphragm valve disposed between the reactor vessel and the mold assembly, and a tubing connecting the diaphragm valve to the reactor vessel and the mold assembly. The diaphragm valve is operable between an open configuration to permit a flow of the flowable forming material through the tubing from the reactor vessel to the mold cavity and a closed configuration to block the flow of the flowable forming material from the reactor vessel to the mold cavity. A filter is disposed between the reactor vessel and the diaphragm valve. The tubing has an upstream tubing section between the reactor vessel and the filter and a downstream tubing section between the filter and the diaphragm valve.
