Title: Glenn R Schaer: Innovator in Metal-Clad Article Production
Introduction
Glenn R Schaer is a notable inventor based in Columbus, OH (US), recognized for his contributions to the field of electroplating and plastic molding. He holds a total of 6 patents, showcasing his innovative approach to manufacturing processes.
Latest Patents
One of Schaer's latest patents is a method for high-speed production of metal-clad articles. This innovative process involves masking a die used for plastic injection molding with a plating resist, allowing only selected areas to be exposed. A conforming anode is then fitted into the die, creating a small clearance between the die cavity surface and the anode. By utilizing a high current density and a turbulent flow of electroplating solution, a metal layer is electroplated onto the exposed mold surfaces in less than a minute. The die is subsequently assembled with a second die to form a mold, into which a plastic molding composition is injected. This composition adheres more tightly to the metal electroplate than the electroplate adheres to the mold surface. As the mold separates, the metal electroplate remains bonded to the plastic, resulting in a metal-clad plastic article. The adhesion can be enhanced by forming nodular growths on the metal electroplate through adjustments in current density and electroplating solution flow-rate. Additionally, the electroplating and molding steps can be combined into an automated process for continuous production.
Another significant patent by Schaer is a method and apparatus for replenishing an electroplating bath with metal. This process involves receiving scrap metal, such as copper wires, in a makeup tank. The gases generated during the electroplating operation are passed into this tank, while the plating solution is directed and sprayed onto the scrap metal, dissolving it. The dissolved copper is then filtered, heated, and reintroduced into the plating tank, ensuring a continuous supply of metal for electrodeposition.
