The 1412 two-way blow-molded pallet is a product formed by a rapidly developing plastic processing method. The blow molding equipment used in the blow molding tray molding process generally requires a relatively large hollow molding machine. Use HMWHDPE plastic extrusion for one-time blow molding. During production, the HMWHDPE plastic is extruded into a tubular plastic parison, which is placed in a split mold while it is hot, and compressed air is injected into the plastic parison immediately after the mold is closed to make the plastic mold The blank is inflated and closely adhered to the inner wall of the mold, and after cooling, shaping and demolding, blow molding trays of various specifications are obtained. The volume of blow-molded hollow containers can reach thousands of liters. The large-scale hollow molding machine that has been developed and manufactured in China has reached 2000L, and the equipment is controlled by a computer. Generally, only HMWHDPE can be used as raw material to produce blow-molded pallets.
