Abstract:
1. A method for rotation molding an article, comprising the steps of: introducing a first flowable material into a mold having an insulating member mounted on a mold wall and having a protrusion extending through an aperture in the mold wall; heating and rotating the mold so as to lay down the first material as a first layer having a thickness small enough so as to form a gap at the insulating member; removing the insulating member so as to expose the gap; introducing a second flowable material without opening the mold; heating and rotating the mold so as to fully cure the second material as a second layer over the first layer and in the gap; cooling the mold so as to solidify both the first and second layers, where the second material is introduced into the mold through the aperture.
