Abstract
A method of and apparatus for blow molding an article having an insert permanently affixed thereto. The insert is placed on a removable member insertable through a wall of a mold section for positioning the insert in spaced relation to a mold cavity wall. An extruded parison is fed between complementary mold sections which are closed about the parison for enclosing a portion of the same. Air is introduced into the enclosed parison to expand the same into conformity with the cavity defined by the mold sections and the insert. Plastic material flows into the spacing between the insert and mold cavity wall to partially encapsulate the insert in sealed, interlocked relation to the wall of the plastic article.
