Title: Innovations in Rubber Compounding by Sidney E Rains

Introduction

Sidney E Rains is an accomplished inventor based in Medina, OH (US). She has made significant contributions to the field of rubber compounding, particularly through her innovative patent related to injection molding processes.

Latest Patents

Sidney E Rains holds a patent for the injection molding of rubber compounds. This invention focuses on reducing vulcanization cycle times by forcing uncured, highly viscous rubber compounds through a thin flow channel upstream of the mold. Notably, the process does not require external heat conduction prior to the mold. Instead, the rubber compound is autogenously heated by the mechanical working energy generated under shear conditions in the channel. This shearing action effectively reduces the compound's viscosity and elevates its temperature above the critical residual scorch range. The end result is a rubber compound with significantly reduced viscosity and a uniform temperature, which is then injected into a mold for continuous flow and vulcanization.
