Embodiment Construction

[0019] The manufacturing process of the present invention is shown in Figures 1-6. Figure 7 is a flowchart of an exemplary embodiment. This process is used to produce press-in-place (PIP) gasket components in a more precise and faster manner. A rigid sample of the shim is made by the process of the present invention, the rigid sample being the same size and shape as the original shim included in the original part.

[0020] Problems can arise if the sample replacement gasket is not laid out and manufactured exactly like the original gasket received in the groove of the engine component. In this regard, PIP gaskets are used in different engine and vehicle components such as oil pans and valve covers. Other products that commonly use PIP gaskets include water pumps, intake manifolds, etc.

[0021] To illustrate the invention in detail, the process will be described in conjunction with an oil pan cover. It should be understood, however, that the process of the present inventio...

Abstract

Processes for making press-in-place (PIP) gaskets. Representative components with gasket cavities (grooves) are prepared and the cavities are filled with a curable molding material. Once the molded gaskets are hardened, they are removed from the cavities. The molded sample gaskets are then measured, preferably by a laser scanner, and drawings are prepared based on the measurement data. Appropriate tooling is then created and the gaskets are produced.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Utility Patent Application Serial No. 13 / 706,128, filed December 5, 2012, the entire contents of which are hereby incorporated by reference. technical field [0003] This invention relates to gaskets, and more particularly to the manufacture of press-in-place gaskets. Background technique [0004] Gaskets are known to provide sealing between parts and components in vehicles and in all types of engines. For example, gaskets are commonly used today to seal manifolds, oil pans, valve covers, and the like. Many such gaskets are made of rubber or elastomeric materials, although some are made of fibrous or felt-like materials. [0005] Depending on their function and sealing performance, these gaskets come in many styles and varieties. Some gaskets are manufactured from rubber to a uniform shape for various applications, such as O-ring seals, and some gaskets are manufactured to ...
