<p>A method for producing a plastic product including an axially extending portion (15), such as a duct or pipe, and a radially extending portion, such as a flange or bracket, is provided. A parison is placed in a first mold cavity defined in a mold and blow molded to form the axially extending potion, and then a movable mold segment (13,14) is moved to a retracted position to define a second mold cavity (18) adjacent to a part of an outer peripheral surface of the axially extending portion thus formed. Then, a second molted plastic material (19) is supplied into the second mold cavity (18) and the movable mold segment (13,14) is again moved to another predetermined position to pressurize the second plastic material to thereby form a radially extending portion. The resulting hollow plastic product is extremely high in structural integrity between the axially (15) and radially extending portions. <IMAGE></p> |
