Ellie Shang , WhatsApp : 008613780912769 the complete PS foam hamburger box production line workflow : where raw material transforms into finished products in one seamless workflow. GPPS resin, combined with foaming additives, enters the two-stage extrusion system. The material melts at high temperature, is injected with a foaming agent under high pressure, and uniformly expands through the die head. After continuous cooling, hauling, and winding, a dedicated PS foam roll is produced. The foam roll feeds into the fully automatic vacuum forming machine. Infrared heating softens the sheet, while a specialized mold — combining vacuum and compressed air — shapes it into clamshell-style foam hamburger boxes in a single step. Finished boxes are precisely cut and separated, then automatically stacked for easy collection and packaging. The mesh-like scrap from cutting is crushed inline, without interruption. With interchangeable molds, the machine produces various sizes of hamburger boxes, fast-food containers, trays, round plates, bowls, and more — truly versatile for a wide range of packaging needs. All scrap material flows into the recycling and pelletizing unit — crushed, melted, and pelletized. The recycled pellets feed back into the sheet production line for reuse, reducing raw material costs and completing a sustainable closed-loop process.
