Rubber Injection Moulding

This review has been written as a practical guide to rubber injection moulding. Many injection moulding processes produce rejects or scrap, because they depend on a b257 of variables. To eliminate waste it is necessary to learn how to recognise the variables that cause problems, and then experiment to understand their interdependence. This can be developed to a fine art and lead towards 'right first time' processing, the commercial ideal. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

This book is aimed at potential customers and personnel in the injection moulding industry, and emphasises quality control, including working to the ISO 9001 Standard. It also highlights the need to consider the economics of operation prior to taking on new projects. Above all, the customer-manufacturer relationship is emphasised at all stages. The customer is encouraged to examine the capabilities of the manufacturer, and the manufacturer is encouraged to develop a good understanding of the exact requirements of the customer. This book is of value to all areas of a company, from those who purchase raw materials to those working in design, technology and production. It will provide a guide for automotive component buyers and should also be useful to a CEO or board member who is new to the industry.

Injection moulding of elastomers for mass produced products, such as those for the automotive industries, is a critical process for rubber product manufacturers. Proces sing equipment and materials are continuously under development for the application. This conference addressed the advances that have been made. The conference proceedings will be of importance to rubber processors, materials suppliers, compounders and end-users alike. The papers discuss developments that are currently available to optimise production from the injection moulding process along with new techniques, materials and equipment.

A record of the proceedings of the Conference on Injection Moulding of Elastomers held at the Borough Polytechnic, London, March 12-14, 1968.

This Practical Guide to Injection Moulding is based on course material used by ARBURG in training operators of injection moulding machines. It comes from many years of experience in this field and has been edited by an expert injection moulder at Warwick University. It will be of use to experts looking to fill gaps in their knowledge base and to those new to the industry. The factors involved in injection moulding, from material properties and selection to troubleshooting faults, are all examined in this book. It covers the equipment types in use and machine settings for different types of plastics. Material flow is critical in moulding and there are sections covering rheology and viscosity. High temperature can lead to poor quality mouldings due to material degradation and this is discussed. There are an exceptional number of figures in this text, with many photographs of machinery and mouldings to illustrate key points. There are also numerous tables listing key properties and processing parameters. Flow charts are included in the chapter on troubleshooting to indicate what can be changed to resolve common problems. Injection moulding in the Western World is becoming increasingly competitive as the manufacturing base for many plastics materials has moved to the East. Thus Western manufacturers have moved into more technically difficult products and mouldings to provide more 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 multi-material and assisted moulding technologies. This Guide will assist progress in developing good technical skills and appropriate processing techniques for the range of plastics and products in the marketplace.
