In a first forming stage, the bottom portion of a mono- molded plastic syringe (a type wherein the whole portion i.e. a main syringe body and a needle portion, is molded unitedly in a cast) is heated and then stretched to a certain length, forming the edge portion like a needle, while the syringe is intermittently moved. Then the syringe is carried to a second forming stage, where the syringe is moved intermittently and the needle portion is heated, then it is bent at a certain angle and is cut in a certain length, forming a completed syringe.
