| Abstract: | Recent progressing methods of improving the wall thickness of extrusion blow molded parts, including new brands of resin, the new technology of controlling the thickness of parison and new extrusion blow molding technology were in troduced. The mentioned parison thickness control technology contained special shaped die and adjustable die. The listed new extrusion blow molding technology covered three-dimensional hollow blow molding, parison temperature difference method, combination of partial vacuum forming and blow molding, and high pressure low-temperature extrusion blow molding technology. |
