I suspect this question is asking about an injection blow molding machine which is a combination of an injection molding machine and a blow molding machine. Blow molding is used to make bottles from glass and plastics and an injection blow molding machine would be used for plastic bottles. When plastic bottles were first made, they were made in two steps. The first step was to mold a preform with an injection molding machine and the second step was to blow mold the preform into the final shape. An injection blow molding machine combines those two steps into a single process.
