Abstract
A method for molding an article by dip or slush molding. The method includes the step of providing a flexible, heat resistant mold member. The mold member maintains its structural integrity during further heating and curing steps. Thus the mold member may therefore be used as an insert in the article 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 article may be any article made from a plastisol; in particular it can be a binaural for a stethoscope having a single or double lumens.
