Abstract
A method of combining a transfer molding operation with a blow molding operation to form an article having wall sections of different thicknesses. The major portion of an extruded parison fed between a pair of mold sections and enclosed thereby is expanded into conformity with the cavity defined by the mold sections. An intermediate portion of the parison is directed into a cavity and displaced therefrom by opposed portions on the mold sections into a desired space to completely fill such spaced forming a wall section having a different wall thickness than the remainder of the article.
