Title: The Innovative Contributions of Gerard R. Thiel

Introduction

Gerard R. Thiel is a notable inventor based in Dysart, Iowa, who has made significant contributions to the field of foundry technology. With a total of four patents to his name, Thiel's work focuses on advanced casting methods and bio-based binder systems that enhance the efficiency and sustainability of foundry processes.

Latest Patents

Thiel's latest patents include a novel casting method that involves admitting molten metal to a mold made from a blend of silica sand and zircon aggregate. This method is particularly innovative as it utilizes a zircon aggregate that exhibits a sharp rise in linear thermal expansion coefficient at high temperatures, specifically between 1200°C and 1600°C. The process also emphasizes cooling the mold and molten metal to solidify the metal and form a cast article, ensuring that one or more surfaces of the mold in contact with the molten metal remain uncoated. Another significant patent is his development of a bio-based binder system for preparing foundry molds. This system incorporates a polymerizable hydroxyl-containing component derived from saccharides, an isocyanate component, and a catalyst, preferably an amine catalyst, to facilitate the polymerization process in the presence of foundry aggregates like sand.
