Title: Innovations by Harry A. Woodrum

Introduction

Harry A. Woodrum is an accomplished inventor based in Muskegon, MI (US). He is known for his innovative contributions to the field of casting technology, particularly in the development of multi-wall ceramic cores. His work has significant implications for the manufacturing of airfoils, such as turbine blades and vanes.

Latest Patents

Woodrum holds a patent for a method of making a multi-wall ceramic core. This process involves creating a fugitive pattern with multiple thin wall elements that provide internal wall-forming spaces for the final core. The pattern is placed in a core molding die cavity, and a fluid ceramic material is introduced to form the ceramic core. After the core is removed from the die cavity, the fugitive pattern is selectively removed to yield a multi-wall green core. This green core is then fired to develop strength for casting, ultimately being used to form an investment casting mold for airfoils.
