Abstract: A duality of portable, lightweight, rapid process and highly efficient injection molds for the mass production of structural insulated polystyrene building panel systems. The non metallic and non conductive molds and mobile supporting base platform are impervious to drastic degrees and fluctuations of positive or negative air, moisture and temperatures. A complete production run per mold is accomplished in approximately 1 minute while absent all time, labor, energy, materials and costs for pre heat cycles as well as all time, labor, energy, materials and costs for cycles of massive amounts of cooling fluids while rapidly self cooled by negative air. The molds can operate simultaneously or alternately while supported by common material feed hopper, air, hydraulic unit and steam/heat supply reservoir.

Abstract: A method of manufacturing composite structural building panels for floors, walls and roofs with the components for securing adjacent panels to each other built into the interior of each panel and serving as a structural component and an optional interlocking component at the same time. The panels attain extreme values of structural integrity, insulation, sound attenuation, air/vapor impermeability and moisture resistance. The panels are non out gassing while having a zero flame spread and are virtually free from deterioration while remaining lightweight and economical. By insertion of optional strut members during manufacturing, the resulting structural values of the panel is drastically increased. The panels are composed of two offset and opposing face frames that each separately lock together within themselves by temporary frictional engagement or puncture crimp.
