Environmentally-friendly dipping molds with extended life and method of manufacturing thereof

Abstract

A dipping mold with extended life whereby a former core (1) is coated with an outer surface (2) of durable material such as NylonTM, polyethylene, polypropylene, PVDF, PEEK and a fluoropolymer or a combination thereof, or epoxies and the coating texturised.

Description

technical field [0001] The present invention relates to dipping molds, and more particularly to dipping molds having a long service life and a method of recycling used dipping molds using a green method. Background technique [0002] Rubber gloves such as examination, surgical or industrial gloves and many other elastic items such as condoms are made in a multi-step process. A clean dip mold, referred to herein as a dip mold, is dipped by hand in a coagulant bath to help the latex mixture for the next step adhere to the dip mold and to help ensure an even distribution of the latex. The dipping mold, covered with coagulant, is then dipped into the latex mixture and eventually travels through a series of ovens to dry the latex mixture formed on the mold. The dipping die is then passed through a dipping line to remove residual chemicals and water soluble proteins from the glove surface. Next, the latex gloves are stripped from the dipping mold. [0003] The dipping mold can ...
