Description: Builds up, fabricates, cures, and assembles various types of plastic, ceramic and composite products and assemblies, including bonded and mechanically-fastened assemblies, where required information is not readily available, operational sequences change or vary considerably, tooling is inadequate or not provided, where it is required to exercise a knowledge of the physical properties of materials such as, but not limited to, thermosets, thermoplastics, plastics, ceramics and composites and their forming and processing characteristics, and of the physical and bonding characteristics of materials and adhesives used. Locates to all critical reference points and assures coordination of parts and subassemblies to exacting tolerances when required in building assemblies, and in incorporating design or modification changes, which materially alter previous assembly references and sequence.
