In the United States soft drink industry, the number of plastic containers went from zero in 1977 to ten billion pieces in 1999. Germany started using this technology a little bit later but is currently one of the leading manufacturers of blow molding machines. The first mass production of plastic bottles was done in America in 1939. Because glass is very breakable, after the introduction of plastic, plastic was used to replace glass in some cases. The technical mechanisms needed to produce hollow-bodied workpieces using the blowing technique were established very early on. Once the variety and production rates went up the number of products created soon followed. During the 1940s the variety and number of products were still very limited and therefore blow molding did not take off until later. This was the beginning of the commercial blow molding process. Enoch Ferngren and William Kopitke produced a blow molding machine and sold it to Hartford Empire Company in 1938. The process principle comes from the idea of glassblowing. Water channels within the mold assist cooling. Once the plastic has cooled and hardened the mold opens and the part is ejected. The air pressure inflates the plastic which conforms to the mold. The plastic workpiece is then clamped into a mold and air is blown into it. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can enter. The blow molding process begins with softening plastic by heating a preform or parison. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. It is also used for forming glass bottles or other hollow shapes.
