Process
Injection blow molding is a two step forming process in a three station machine. First, a parison, a short test-tube-like piece is injection molded by a conventional injection molding process, normally with threads or other required features. The parison is then rotated to a station with a blow molding tool. Hot air is injected into the parison, which expands it into the mold cavity. The last stop is a stripper station that removes the finished part.
