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.

This book details the factors involved in the injection moulding process, from material properties and selection to troubleshooting faults, and includes the equipment types currently in use and machine settings for different types of plastics. Material flow is a critical parameter in moulding and there are sections covering rheology and viscosity. High temperature is also discussed as it can lead to poor quality mouldings due to material degradation.The text is supported by 74 tables, many of which list key properties and processing parameters, and 233 figures; there are also many photographs of machinery and mouldings to illustrate key points. Troubleshooting flow charts are also included to indicate what should be changed to resolve common problems.Injection moulding in the Western World is becoming increasingly competitive as the manufacturing base for many plastic materials has moved to the East. Thus, Western manufacturers have moved into more technically difficult products and mouldings to provide enhanced added value and maintain market share. Technology is becoming more critical, together with innovation and quality control. There is a chapter on advanced processing in injection moulding covering multimaterial and assisted moulding technologies. This guide will help develop good technical skills and appropriate processing techniques for the range of plastics and products in the marketplace.Every injection moulder will find useful information in this text, in addition, this book will be of use to experts looking to fill gaps in their knowledge base as well as those new to the industry.ARBURG has been manufacturing injection moulding machines since 1954 and is one of the major global players. The company prides itself on the support offered to clients, which is exemplified in its training courses. This book is based on some of the training material and hence is based on years of experience.

Latex-based technology forms a sizable fraction of natural and synthetic rubber technology and an introduction to the important technologies is beneficial to all practicing technical personnel. This book offers a condensed practical guidance on the technologies used for the production of important latex products. The book begins with a short history of natural rubber latex, formation in the tree and the tapping, storage and conversion of latex to marketable forms. It discusses preservation and concentration of natural rubber latex and the most widely used latex compounding ingredients. Dipping and casting techniques are discussed, as well as the technology related to foams, threads and adhesives. In addition, the book offers an introduction to important lattices such as styrene-co-butadiene rubber, acrylonitrile-co-butadiene, polychloroprene, polyvinyl chloride, and so on. Fully illustrated throughout, with photographs from actual production sites, this practical guide is ideal for academics, research and development managers, students of polymer technology and all those working in the latex industry.

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.

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.
