This monograph focuses on the technical aspects of the rotational molding process, as well as on ancillary aspects such as polymer characteristics, powder grinding, mold surface preparation, part finishing, and mechanical and structural performance of finished parts. It presents a seamless story of the advanced aspects of the process. The text compares rotational molding to blow molding and twin sheet thermoforming; discusses process energy conservation and efficiency considerations; covers the importance of oven and cooling chamber design; treats part design issues including powder flow into angles; and more. A troubleshooting guide is included.

From the Preface: “...[This] monograph relies heavily on technologies in other disciplines, such as powder mechanics, heat transfer, and soil mechanics. Although it follows other treatises in rotational molding...it distinguishes itself from them by approaching the technical aspects of the subject in a single voice. It was not our objective to repeat material found in other treatises but, instead, to extend the technological aspects of the industry...”

Target Audience: Plant managers, engineers, designers, product managers, students, and other readers concerned with the rotational molding process.
