Abstract
This invention relates to the use of a flexible, heat resistant mold member. The mold member is useful in molding processes such as dip or slush molding. The mold member maintains its structural integrity and may therefore be used as an insert in the article being molded to provide flexible stability at specific locations within the article. The mold member is made of a material which is substantially non-reactive with the molded article. The molded article may be any article made from a plastisol such as a binaural for a stethoscope having single or double lumens.
