  • Mold having elastomeric mold member therewith
    Patent number: 5380182
    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.

  • Method of forming a molded article using a mold having an elastomeric mold member
    Patent number: 5324471
    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.
