Die Casting Dies Machines Methods

This work describes the origin, procedure, and advantages of Die casting. It is a metal casting technique in which one pushes molten metal under high pressure into a mold cavity. Along with presenting the general facts on the subject, the writer goes into detail, explaining the operation of die casting machines, the process of making dies, and some quick tips to help the manufacturers improve efficiency. In addition, the book contains a chapter dedicated to the die casting company E. B. Van Wagner Mfg. Co., illustrating how their operations are carried out. Contents include: Die Casting Making Dies for Die-Casting Machines Van Wagner Mfg. Co.'s Die-Casting Practice

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact.

Originally published in 1913. TABLE OF CONTENTS Chapter I. Die Casting Chapter II. Making Dies for Die-Casting Machines Chapter III. Van Wagner Mfg. Co.'s Die-Casting Practice EXCERPT FROM DIE CASTING: DIES - MACHINES - METHODS Die-casting, a comparatively recent method for producing finished castings, is rapidly proving itself an important factor in the economical manufacture of interchangeable parts for adding machines, typewriters, telephones, automobiles and numerous other products where it is essential that the parts be nicely finished and accurate in dimensions. The term "die-casting" is self-explanatory, meaning "to cast by means of dies"; described briefly, the process consists of forcing molten metal into steel dies, allowing it to cool in them, and then opening the dies and removing the finished casting. It is the purpose of this treatise to give a general outline of the die-casting process, showing its possibilities and limitations, and also to give a description of the die-casting machinery and its operation, of the fundamental principles involved, and of the methods used in the die-making. Illustrative examples of the best types of dies, based on results obtained from actual experience, will also be given.

A frequently misunderstood technology, die casting is considered the shortest route between raw material and near net shape. For many decades, high pressure die casting was viewed as an art based upon "seat of the pant" strategies. However, many of these crude reactions actually worked because the fundamental process is quite forgiving of eccentricities. Exploring these reactions with scientific logic, Die Casting Engineering presents a broad study of each procedure in the die casting process and clearly outlines its basic science and principles. This guide is written in a reader-friendly and logical format by an experienced authority in quality and productivity enhancement, tooling design, metal feed system analysis, temperature management, and environmental regulation. While its scope is broad and covers the many facets of die casting, the book's main focus is on function, problem identification and solution, and strategic logic. Generously illustrated, it provides a comprehensive explanation of why high pressure die casting is reliable, predictable, and teachable.

Workshop Processes, Practices and Materials is an ideal introduction for entry level engineers and workshop technicians, as well as engineering university students with little or no practical experience. With detailed illustrations throughout and simple, clear language, this is a practical introduction to what can be a very complex subject. It has been significantly updated and revised to include new material on current Health and Safety legislation, gauging and digital measuring instruments, as well as modern measuring techniques such as laser scan micrometer, co-ordinate and visual measuring systems. A new chapter on an introduction to CNC milling and turning has been added. This book covers all standard workshop topics, including safe practices, measuring equipment, hand and machine tools, metal and plastics materials, joining methods including welding, presswork, primary forming, casting and moving loads, making it an indispensable handbook for use both in class and the workshop. Its broad coverage makes it a useful reference book for many different courses worldwide. Health and Safety chapter covers current best practice and has been checked by a certified health and safety examiner. Addition of modern measuring techniques using laser scan micrometer, co-ordinate and visual measuring systems. Addition of an introduction to CNC milling and turning.
