Title: Innovations of John R Wolfe, Jr.
Introduction
John R Wolfe, Jr. is a notable inventor based in Rogers, AR (US). He has made significant contributions to the field of plastic extrusion technology, holding a total of three patents. His work focuses on improving the efficiency and effectiveness of plastic pelletizing apparatus.
Latest Patents
One of his latest patents is the Internally Insulated Extrusion Die. This innovative die assembly is designed for plastic pelletizing apparatus that includes a cooling bath into which the plastic is extruded. The die assembly features a heated main body with first and second oppositely disposed exterior faces connected by a series of small extrusion passageways. A layer of thermal insulation material covers the second face, while a cover member, which is exposed to the cooling bath, is positioned over the insulation and joined to the main body. The design incorporates wear-resistant insert members made from a material with a higher coefficient of thermal conductivity than that of the cover member. These inserts extend from the outer surface of the cover member through the insulation into the main body. The extrusion outlet orifices formed through the insert members continue the extrusion passageways of the main body. This configuration enhances heat flow from the main body to the outer die face, particularly around the orifices, thereby reducing the risk of freeze-off and plugging due to premature solidification of the extruded plastic.
