Publication number: 20240083084Abstract: A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: Guill Tool & Engineering Co., Inc.Inventors: Richard Roy Guillemette, Robert Peters, Christopher J Hummel
