A material handling and mold filling system is provided which directs the flow of molten plastic material from an extruder and allocates the molten material to a plurality of nozzles through the use of independently operated, variable valves. The system therefore provides independent streams of molten plastic material having variable temperatures and flow rates or volumes to particular sections or regions of the mold. This independent temperature or flow of molten plastic material facilitates the complete, rapid and accurate filling of the molds, reducing turbulence and other temperature or flow-related imperfections in the finished components. A multiphase material handling system is also disclosed for expeditious sequential and simultaneous filling and pressing of the mold and extracting the completed component from the system.

An apparatus for forming an injection molded article is disclosed. The apparatus includes a pumping system to deliver a silicone formulation to a mold, the silicone formulation having a viscosity of about 50,000 centipoise to about 2,000,000 centipoise. The mold has an exterior housing and an interior cavity therein, wherein the silicone formulation flows into the cavity of the mold. The apparatus further includes a source of radiation energy, wherein the radiation energy substantially cures the silicone formulation within the cavity of the mold to form the injection molded article. The present disclosure further includes a method of forming the injection molded article and a mold for an injection molded article.

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).

A molding apparatus reduces waviness or deformation of fibers. The molding apparatus includes a fiber feeder that feeds fibers, a resin feeder that feeds a resin, a curing accelerator that accelerates curing of the fed resin while the fed fibers are being tensioned, and a transporter that relatively changes a feeding position of the fibers, a feeding position of the resin, and an accelerating position of the curing.
