Rotational Moulding of Plastics

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. Now, 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. The second edition of this book, first published in 1992, has been extensively updated and expanded by its authors, who are leaders in their specialities within the field of rotational moulding. It provides an introduction to the subject, as well as giving comprehensive coverage of the state-of-the-art. There are new chapters on rotational moulding of liquid polymers and on pin-holes and bubbles in rotationally moulded products. It 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.
