blow tray (blow moulding pallet) is a rapid development of processing methods and molding plastic products. tray blow molding process used in blow molding equipment generally require more large-scale blow molding machine, currently the largest super blow molding equipment for the 2000L's unit, the use of a plastic extrusion blow molding HMWHDPE, production will thermoplastic resin by extrusion into a tubular plastic parison, hot (or heated to soften the state), placed outside the mold, immediately after the closed mold in the plastic parison within the pass into the air, so that the plastic inflation and tight Parison attached to the inner walls of the mold, the cooling setting ejection, which have a variety of blow molding tray . At present the volume of blow molding hollow containers of up to several thousand liters, the country has made large-scale R & D blow molding machine has reached 2000L, using a computer-controlled equipment. Production of the tray generally only used HMWHDPE blow as raw materials. Therefore, the quality of their products inside the plastic tray the best quality level.
