Benefits of technology

The present invention relates to a method and apparatus for manufacturing a component with an attachment molded thereon and an insert. The method involves using a lubricant during the attachment process, but it can cause defects during the molding process. To prevent this, the insert is treated by covering it with a coating, such as zinc stearate, which dissolves in the molding material and prevents lubricant from seeping into the insert. This results in a gasket with no defects and improved quality. The technical effect of this invention is to improve the manufacturing process of components with attachments and inserts.

Problems solved by technology

As a result, the lubricant impedes molding material from flowing within the mold and properly forming the attachment.

Abstract

An apparatus and method for manufacturing an attachment including an attachment molded thereon and an insert is shown. The insert is treated so that the lubricant used while affixing the insert to the component does not seep into the insert. The component is processed and inserted into a mold, in which molding material is introduced. Because the lubricant did not seep into the insert, it is not squeezed out during the molding process and does not impede the flow of the molding material. The molding material forms the attachment, which is molded onto the component. The attachment has less defects than attachments molded onto the component using methods of the prior art.

Description

CROSS REFERENCE TO RELATED APPLICATION DATA [0001] This Application claims the benefit of priority of provisional U.S. Patent Application Ser. No. 60 / 642,630, filed Jan. 10, 2005.BACKGROUND OF THE INVENTION [0002] The present invention pertains to an apparatus and method for making a component including an attachment molded thereon and an insert for the component. [0003] Components often have holes formed within the components. Inserts are affixed to the holes and allow the components to be assembled with other parts, typically to form an assembly that includes the component and the other parts that the component is assembled with. Attachments can then be molded onto the components by an injection molding process. The attachments can serve numerous purposes, such as providing a seal between the component and the other parts with which the component is assembled. [0004] For example, windage tray type components work in conjunction with and are connected to other parts to form oil pan...
