Abstract:
1. A system for forming aggregate materials comprising: a lower open-topped mold for receiving a heat moldable material comprising a foaming agent; an upper mold that cooperates with the lower open-topped mold to form an enclosure; an actuation assembly coupled to the lower open-topped mold, the upper mold, or both to generate relative inward motion between the lower open-topped mold and the upper mold and relative outward motion between the lower open-topped mold and the upper mold; a heating system in thermal communication with the lower open-topped mold and the upper mold; a pressure sensor operably coupled to the lower open-topped mold, the upper mold, or both, wherein the pressure sensor transmits a pressure signal indicative of back pressure provided by the heat moldable material; and a controller communicatively coupled to the actuation assembly and the heating system, wherein when the heat moldable material is received by the lower open-topped mold, the controller executes machine readable control logic to:
