Rotational Molded Plastic Tricon Containers

Abstract

A study is made to determine the feasibility of fabricating a full size TRICON container by encapsulating a metal structural framework with a plastic material by using the rotational molding process. The effort included a survey of commercially available rotational molding grade plastics and metals, the design and fabrication of a subscale mold and subscale containers. Materials were selected, and a subscale mold was fabricated. Techniques were developed for encapsulating a structural framework with plastic using the rotational molding process. However, stress cracks developed in the plastic after molding. Although several technical approaches were attempted, techniques for eliminating the stress cracks could not be developed. This report contains a body of information on molding characteristics of various rotational molding grade plastics not previously available to the plastics industry.
