Abstract
An over-molded product, such as a container, and a method of manufacture. The product is primarily used for enclosing hazardous materials and is formed by utilizing a thermosetting plastic material in a reaction injection molding process at low temperature and pressure to envelop adjacent portions of two or more components to form the desired product. This provides a mechanical interface but avoids a chemical reaction which would degrade the components.
Claims20
A method of forming an over-molded product comprising multiple components without affecting the chemical and physical integrity of said components;
- comprising the steps of positioning a mold around said components, introducing a thermosetting plastic over-molding material under low pressure and low temperature conditions into said mold to provide a mechanical interface between said components and said plastic material, and forming said product without a chemical reaction and physical degradation within said components.
The method of claim one wherein said step of introducing said plastic material into said mold member comprises reaction injection molding.
An over-molded product comprising multiple components and a thermosetting plastic over-molding material formed around at least a portion of said components, said over-molding material having a mechanical interface with said components without chemical reaction therewith, said components retaining their chemical and physical integrity during formation of said product.
