Description
The polymer and plastics field is now one of the most mature areas of materials technology, yet there continues to be a plethora of new uses and applications for these materials. Central to the cost-effective development, processing and serviceability of new components is the need for a thorough understanding of the parameters involved in forming these components. Injection moulding is the most versatile technique, and thermoplastics are the most widespread and versatile material. It is recognized that mistakes made during the processing and forming of components can have damaging effects on mechanical integrity and design limits. Good component design and serviceability starts with good mould design: a poor mould can introduce unwanted stresses and weaknesses into components. This book provides a practical, step-by-step guide to injection mould design. All aspects are covered and pitfalls highlighted, leading to an unveiling of a technology regarded by many as something of a black art.
This book should be of interest to production personnel involved in designing and using moulds; production managers, mould designers, technicians; graduates in the plastics and polymer processing industries and advanced undergraduates and researchers in materials science and technology.
