Abstract
An improved process for producing integral, composite handles having cushioned comfort grips, for appliances such as electric steam irons, comprising a first step of injection molding a one-piece handle substrate of strong, rigid, resinous composition having the desired predetermined shape and design, including a recessed, wrap-around area corresponding to the area of the handle which will be gripped by the hand of the eventual user of appliance. The present process comprises a second step of injection molding an integral, outer, soft, contoured layer of foamed resin into the recessed, wrap-around area of the rigid plastic handle substrate, to form a smooth, compressible, comfort grip surface area of the composite handle for engagement with the hand of the user.
