This report explains the fundamentals of rotational moulding, with particular reference to advances in the key areas of materials, machinery, moulds and process control. He considers relationships between processing conditions and product properties, and looks briefly at the future of the process, and the likely advances still to be made. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database provides useful references for further reading.
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.
