This book is designed to serve as a comprehensive study of foundry technology. This will serve as a bridge between the study of the basic and scientific principles of foundry technology and their applications in the industries. Its further aim is to impart the knowledge of modern techniques of casting production and other developments in the founding of metals. The book is conceived as a text book and work of reference for the use of students and teachers in engineering institutions. This is also intended for higher education in the subject of managerial and technical staff in the casting industry. It is hoped that the book will be highly useful to all the metallurgists and foundry men. In particular the aim has been to assist engineers and engineering students in realizing the importance of casting in design and selection of materials. The subject has been considered comprehensively to include all aspects relevant in the field of casting to help industry as well a academicians. The bo
