Opis

Over the years 1984 to 1989, we published a series of articles on the molding of thermoplastics, and of thermosetting materials, in the monthly magazine British Plastics and Rubber (B P & R). These articles were very well received and we also received a large number of requests for reprints. The articles were also translated into languages other than English. In order to cater for what is obviously a need in both the ther- moplastics, and the thermosetting, molding industries, we there- fore brought the information together and produced it in book form. To make the material easier to handle we produced it in the form of several books and this is one of them. We can only hope that the information so presented, serves you well and that you find the information useful. We in turn would like to thank the editor of the magazine B P & R for helping us in this matter. Thanks are also due to our many friends and colleagues throughout the molding industry for their useful help and advice: in particular, the company Moldflow (Europe) limited deserve a special mention as they allowed us to extract information from their extensive data base.
