Title: Innovations of Hans-Joachim Roesler in Thermal Casting Technology

Introduction

Hans-Joachim Roesler is a notable inventor based in Braunschweig, Germany. He has made significant contributions to the field of thermal casting technology. His innovative approach has led to the development of a unique process that enhances the production of thermally loaded castings.

Latest Patents

Roesler holds a patent for a process for producing a thermally loaded casting. This process involves creating a casting mold from a slurry using a wax model and a polymer foam. The polymer foam is either fixed to the wax model or introduced into a cavity. During the casting process, the liquid superalloy penetrates the open-cell structure of the casting mold, resulting in an integral cooling structure formed during the solidification of the casting. This method allows for the production of single-crystal or directionally solidified castings. Additionally, it is possible to vary the cell size of the polymer foam, produce a cooling structure and base material separately, and coat the cooling structure with a ceramic protective layer.
