Title: Jeff Crist: Innovator in Automotive Sound Deadening Technology

Introduction

Jeff Crist is an accomplished inventor based in Sterling Heights, MI (US). He holds 2 patents that showcase his innovative contributions to the automotive industry. His work primarily focuses on sound deadening materials and body panel assembly methods, which are crucial for enhancing vehicle performance and comfort.

Latest Patents

One of Crist's latest patents is for a two-layer pumpable sound deadener. This innovative material is designed to be applied through a pair of extrusion heads mounted on a single mount. A robot, utilized in high-speed mass production automotive assembly lines, moves the door panel relative to the stationary extrusion heads. This allows for the simultaneous application of two layers onto the interior side of the door. The first layer consists of a thermosetting composition containing epoxy, rubber, and a catalyst, which adheres directly to the door panel. The second layer, made from a thermosetting composition containing an epoxy resin, a thermoplastic copolymer, and a curative, adheres directly to the first layer. This design prevents noise transmission from the body or door panel by ensuring that the edges of the second layer are positioned inside the corresponding edges of the first layer.

Another significant patent by Crist is a method of making a body panel assembly for a vehicle. This method involves providing first and second panels, applying an adhesive, positioning the panels, hemming them together to form a subassembly, applying a coating to at least a portion of the subassembly, and heating the subassembly to partially melt the adhesive. This innovative approach streamlines the manufacturing process and enhances the structural integrity of vehicle body panels.
