Practical Guide to Rotational Moulding

Rotational moulding is 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 stress-free articles, with uniform wall c098 and complex shapes. Rapra's Practical Guide to Rotational Moulding describes the basic aspects of the process and the latest state-of-the-art developments in the industry.

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.

Practical Guide to Rotational Moulding, Third Edition, takes a step-by-step approach to rotomoulding, covering applications, moulds, machinery, materials, and design. This third edition has been thoroughly revised to include the latest advances, including novel materials and moulds, new products, and automation. The book begins with a chapter that introduces the rotational moulding process, analyses advantages and disadvantages, and explores common applications for rotomoulded products. The subsequent chapters provide detailed, methodical coverage of moulds, machinery, materials, and design for functionality, supported

The Basics of Troubleshooting in Plastics Processing is a condensed practical guide that gives the reader a broad introduction to properties of thermoplastics plastics, additives, the major processes (extrusion, injection molding, rotational molding, blow molding, and thermoforming), as well as troubleshooting. The main goal is to provide the plastics processor with an improved understanding of the basics by explaining the science behind the technology. Machine details are minimized as the emphasis is on processing problems and the defects in an

This handbook provides a framework for understanding how tocharacterize plastic manufacturing processes for use introubleshooting problems. The 21 chapters are authored bywell-known and experienced engineers who have specialized knowledgeabout the processes covered in this practical guide. From the Preface: “In every chapter, the process is described and the mostcommon problems are discussed along with the root causes andpotential technical solutions. Numerous case studies are providedthat illustrate the troubleshooting process. Mark A. Spalding,The Dow Chemical Company

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.

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

This practical guide begins with general background to the polyethylene family, with price, production and market share information. It describes the basic types of polyethylene including virgin and filled polyethylene, copolymers, block and graft polymers and composites, and reviews the types of additives used in polyethylene. It gives the low down on the properties, including, amongst others, rheological, mechanical, chemical, thermal, and electrical properties. It goes on to describe the processing issues and conditions for the wide range of techniques

Polypropylene is now the third largest consumed plastic material after polyethylene and polyvinyl chloride. This book discusses the advantages and disadvantages of working with polypropylene, offering practical comment on the available types of polypropylene, its mechanical properties and in-service performance, and processing. Comparisons with other common plastics are also provided, which highlight the advantages of this polyolefin.

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

The new edition of this bestselling reference provides fully updated and detailed descriptions of plastics joining processes, plus an extensive compilation of data on joining specific materials. The volume is divided into two main parts: processes and materials. The processing section has 18 chapters, each explaining a different joining technique. The materials section has joining information for 25 generic polymer families. Both sections contain data organized according to the joining methods used for that material. * A significant and extensive update from experts

Applied Plastics Engineering Handbook: Processing, Materials, and Applications, Second Edition, covers both the polymer basics that are helpful to bring readers quickly up-to-speed if they are not familiar with a particular area of plastics processing and the recent developments that enable practitioners to discover which options best fit their requirements. New chapters added specifically cover polyamides, polyimides, and polyesters. Hot topics such as 3-D printing and smart plastics are also included, giving plastics engineers the information they need to take

Fluoroplastics, Volume 2: Melt Processible Fluoropolymers - The Definitive User's Guide and Data Book compiles the working knowledge of the polymer chemistry and physics of melt processible fluoropolymers with detailed descriptions of commercial processing methods, material properties, fabrication and handling information, technologies, and applications, also including history, market statistics, and safety and recycling aspects. Both volumes of Fluoroplastics contain a large amount of specific property data useful for users to readily compare different materials and align material structure with end use

The explosion of plastic material development continues to generate a proliferation of conversion processes and variants of these methods. Unfortunately, most books on plastics conversion focus on a single process, such as injection molding, limiting their usefulness to readers without prior knowledge of the field. Few, if any, single-source texts adequately describe and compare each of the plastic conversion processes together. Plastic Conversion Processes: A Concise and Applied Guide addresses that need. It provides a basic overview of each of
