Liquid-Injection-Molded, Lightweight, Insulated Footwear

Abstract

The purpose of this work was to develop a suitable process for manufacturing lightweight, insulated footwear (LIF) on automated, liquid-injection-molding (LIM) equipment. Improvements in compounds, mold design and chemistry were incorporated into a completely new method for fabricating the LIF; this method, adaptable to automation, has the capability of molding a boot with a low-density upper and higher density outsole in one cycle. The improved molds, compound formulations, processing equipment and techniques produced good quality LIF. Thirty pairs of LIF were made, and 25 were sent to Alaska for testing.
