Many injection moulding processes produce rejects or scrap, because they depend on a number 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. There are many factors that contribute to success or failure in rubber injection moulding from the design stage of a product, through choosing and setting up machinery, to experimenting to find the best operating conditions. Varying any one factor, such as the polymer additives, can affect the ability of the equipment to adequately process the rubber. The 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.
