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.
Claims8
A method of forming an over-molded product comprising multiple components of a low melting point plastic without affecting the chemical and physical integrity of said components;
- comprising the steps of positioning mold members around a portion of said components, injecting a thermosetting plastic over-molding material at a pressure below 40 pounds per square inch and a temperature ranging from 60°-90° F. between said mold members and said portion of said components to provide a mechanical interface between said portion of said components and said plastic material, and forming said product without a chemical reaction and physical degradation within said portion of said components.
