Download Free Rotational Molding Technology Book in PDF and EPUB Free Download. You can read online Rotational Molding Technology and write the review.

This book clarifies and quantifies many of the technical interactions in the process. It distinguishes itself from other books on the subject by being a seamless story of the advanced aspects of the rotational molding process. There are seven chapters within the book. The US market for rotational molding products was one billion pounds in the year 2000. The growth of the rotational molding industry has grown at 10 to 15% per year. With this growth has come an increasing need for details on the complex, technical aspects of the process.

Rotational moulding has been available as a processing method for hollow plastic products for more than forty years, but for a long time it was regarded as a slow method limited to only a few plastics. Within the last ten to fifteen years there has been a dramatic change. Engineers and designers recognise the scope that rotational moulding offers for the production of relatively inexpensive, complex shapes with low levels of moulded-in stress. Materials suppliers are continually developing new grades of plastics as well as a wider selection of materials suited to the process. In addition, machinery suppliers are producing more sophisticated moulding equipment so that the moulder now has control over the process that was previously thought impossible. For its second edition, this book has been updated and expanded by the authors, who are leaders in their specialties within the field of rotational moulding. It continues to provide an introduction to the subject, as well as giving comprehensive coverage of the state-of-the-art. Two new chapters have been added. These cover the important areas of pin-hole removal from rotomoulded products and the rotational moulding of liquid polymers. In both cases the new material is the result of extensive research, and the results will be of considerable practical interest to moulders. The book will surely be welcomed again by moulders, materials and equipment suppliers, engineers and designers, and by lecturers looking for up-to-date information to include in their courses.
Rotational moulding (also called rotomoulding or rotocasting), is a low pressure, high temperature manufacturing process that offers a very competitive alternative to blow moulding, thermoforming and injection moulding for the manufacture of hollow plastic parts. It offers designers the chance to produce relatively stress-free articles, with uniform wall thickness and potentially complex shapes. This second edition of the very popular Practical Guide to Rotational Moulding describes the basic aspects of the process and the latest state-of-the-art developments in the industry. It is completely revised and is extensively illustrated.This guide will be of interest both to students of polymer processing and those who work with rotational moulding equipment.
A highly versatile process, rotational molding allows for incredible design flexibility with the added benefit of low production costs. One of its advantages over other plastics processes is that one can mold more complex shapes with uniform wall thickness. This book provides an introduction to the design, materials, tooling, and process, and helps readers understand and apply the manufacturing techniques involved in rotational molding.
