High moisture content in PET can effect the way it performs when processed. For more information about PC, please see our polycarbonate resins article. Varying the wall thickness solves the problem of non-uniformity of the hanging parison as the weight of the formed portion would otherwise stretch the hot and still-forming section above it. Plastic bottle manufacturing takes place in stages. Here, a thin steel rod, called a mandrel, slides into the neck of the parison where it fills the parison with highly pressurized air, and stretch blow molding begins: as a result of the pressurized air, heat, and pressure, the parison is blown and stretched into the mold axially and radially, where it assumes a bottle shape. You can watch the video tutorial here. The molding process typically takes place in an industrial setting with trained plastic technicians. The mold must be cooled relatively quickly, so that that the newly formed component is set properly. LDPE is amorphous while HDPE is crystalline which accounts for LDPE’s greater ductility and HDPE’s higher rigidity. :)Subscribe and like please.
