Casting and Moulding e-bog

Casting and Moulding: Foundry Techniques for Schools attempts to present certain aspects of foundry work in a simple and accurate manner, and explore the possibilities it holds for schools. The techniques described range from the very simple and relatively inexpensive to the more difficult and costly, but all have been tried and found to be successful in schools. Each technique is described in its own chapter. These include techniques such as stack molding, snapflask molding, pattern plates, free core casting, and casting into dies. The chapters are long enough to be informative, yet short enough to maintain the interest of the reader. It is hoped that the methods described and the projects used will encourage pupils to design and develop their own castings. This book does not suggest that existing methods of casting in schools are either obsolete or inadequate. Neither is it meant to replace the traditional functions of the class teacher. What it has tried to do is to present alternative methods of producing castings which will supplement techniques now being used successfully in a variety of schools, and to assist and encourage teachers who are thinking of introducing molding as a new aspect of craft work.
