Injection moulding is the most important moulding process used by the plastics industry and some idea of its importance can be obtained by considering the following figures. The value of the UK market for plastics processing equipment was £60 million in 1977. Of this sum, £23 million was spent on injection moulding machines, that is, 40 % of all the money spent on plastics processing equipment in the UK. It has been estimated that one-third of all plastics materials are processed by injection moulding. At the present time the process is of greater importance to the thermoplastics industry but its relevance to the thermoset industry should not be ignored. Most ofthe equipment now used is based on single-screw pre-plasticising units. Once these machines had become established, in the 1960s, it was felt that the ultimate had been reached in machine design and utilisation. However, since that time, machines, processes and materials have undergone extensive development to make injection moulding safer, more reliable, easier to use and more economical to operate. The purpose ofthis book is to review some of the developments that have taken place in this very important area. These developments are described by specialists in the field, who have extensive industrial experience and whose contribution will therefore be of immediate relevance to those concerned with the usage and application of this, the most important plastics moulding process.

In the field of polymer technology, injection moulding is the most important moulding process. Because of the size of that industry and the rate of development which it attracts, it is impossible to present, in a single reasonably sized volume, all of the developments that have taken place in recent years. The purpose of this book is therefore to present selected topics which contribute to, or exemplify, develop ments in this important area. Each year considerable development takes place in the area of machine and process control and these developments receive con siderable publicity in the trade press. Another area which advances at the same pace, but which seems to receive far less publicity, although it is equally important, is the area of mould design and manufacture. It is important because profitability is dependent upon the design, manufacture and operation of the mould. It is for this reason that several chapters relating to mould design have been included in this, the third volume in this series. The topics covered include advances in mould manufacture, the use of runnerless systems to aid productivity, and others showing how the applications of computers can greatly assist the moulder to obtain a more productive unit.

In the field of plastics technology, the process of extrusion is widespread and important. It is employed in the compounding and pelletising of plastics materials, in their conversion into products (such as profiles, pipe, hose, sheet, film or bottles) and in the coating of wires, cables, paper, board or foil. A major reason for its use is the screw extruder's ability to melt efficiently and pump continuously large amounts of plastics materials. The understanding of the melting/pumping operation of the extruder and the development of larger and faster-running machines so as to give higher outputs have been given great attention and the results have been widely published. However, the whole manufacturing technology for extruded products has also developed, particularly in recent years. This has occurred not only by the use of modern screw extruders, but also by the incorporation of improved process control systems, the better design of dies and extrudate handling machinery and by the utilisation of improved plastics materials and additives. It is the purpose of this book to present selected topics which contribute to, or exemplify, these developments in extrusion-based processes.

Injection moulding is one of the most important methods of manufacturing plastics products. Through the development of sophisticated micro processor control systems, the modern injection moulding machine is capable of producing precision mouldings with close tolerances in large numbers and with excellent reproducibility. This capability, however, is often limited by the lack of a proper appreciation of mould design. The mould, or tool as it is often called, is at the heart of the injection moulding process. Its basic function is to accept the plastic melt from the injection unit and cool it to the desired shape prior to ejection. It is not, however, simply a matter of the mould having an impression of the shape to be moulded. Many other factors have to be taken into account - for example, the ability to fill the mould impression properly and efficiently without inducing weaknesses in the moulding and the efficient cooling of the moulding in order to maximise production rates without diminishing the quality of the moulding. In addition, the type of mould, gate and runner system, and ejection system which will best meet the needs of a particular job specification have to be determined. In our experience lack of attention to such factors leads to the mould limiting the ability of the injection moulding machine and preventing the process as a whole from achieving its true potential.

Metal injection moulding (MIM) is a manufacturing process used for small-to-medium-shaped precision components. This chapter provides a detailed overview of MIM and includes descriptions of the principles of the process such as powders, binders, mixing and feedstock analysis, injection moulding, binder removal (debinding), sintering and post-sintering. The chapter concludes with case studies and the design requirements for MIM and its applications.
