Abstract
A method of manufacturing a polypropylene vessel using a single-step injection stretch blow molding machine using a heat-conditioning step. The method may include providing a chemical composition comprising polypropylene, forming a preform vessel of the chemical composition in a second shape, heating the preform vessel at a plurality of positions on the preform vessel with heat pots, wherein each of the heat pots is configured to heat a corresponding one of the plurality of positions on the preform vessel by raising a temperature of the heat pot to a respective temperature, wherein each respective temperature of each of the heat pots is different from another respective temperature of another of the heat pots, wherein the temperatures of the heat pots are based on the desired first shape of the product. The method may include forming, from the heated and expanded preform, a second vessel in a desired first shape.
