The Continuous Double Belt Press assembles raw inputs (unrolled or scattered) onto an extended lower belt, consolidates them under heat and pressure, then anneals; sheets can then be embossed, printed, laminated, or trimmed. It produces 1/16″–9/16″ thick sheet up to 5 feet wide in multi-layer constructions, and can commingle post-consumer and post-industrial recycled resins with virgin plastics (PE, PETG, PVC, ABS, PET). Three technology levers define the platform: lightweighting (glass-microsphere or cork fillers cut weight by more than 25% at 10 wt% loading), dimensional stability (glass fiber or mats reduce the coefficient of linear thermal expansion by more than 50% versus virgin resin), and cost (using dissimilar and recycled materials).
