Manufacturing Process

The text begins with introducing factory system, need of products made by industries, importance of manufacturing process, types of manufacturing processes and machine tools.

Chapter 2 on sand casting presents history of casting, types of casting process, elements of sand casting, pattern making with topics, viz. types of patterns, types of pattern material, pattern allowances, types of sands, properties of sand-casting mould, steps of sand casting, core, and gate and its types. It is followed by a chapter on moulding machines and melting furnaces, which gives a comprehensive presentation of thermoforming moulding, injection moulding, compression moulding, transfer moulding, extrusion moulding, blow moulding, rotational moulding, hydroforming, laminating, and metal furnaces, viz. Cupola furnace, induction furnace, and open-hearth furnace. Chapter 4 presents special casting processes, which include shell casting, investment casting, ceramic mould casting, pressure diecasting, viz. hot chamber process in high pressure diecasting, cold chamber high pressure diecasting and low-pressure diecasting, and horizontal centrifugal casting, vertical centrifugal casting, CO2 casting process, stir casting, squeeze casting, full mould casting, magnetic casting, and casting techniques for single crystal components. It is followed by a presentation of different casting defects. Chapter 5 is on gas welding, which is a metal joining process. This chapter includes key terminologies of welding, gas welding techniques, viz. Air-Acetylene Welding (AAW), Oxy-Acetylene Welding (OAW), Oxy Hydrogen Welding, and Pressure Gas Welding (PGW). Next, the chapter 6 on arc welding includes gas shield tungstan arc welding, metal arc welding, submerged arc welding, gas shield metal arc welding, flux cored arc welding (FCAW), electro slag welding, electro gas welding (EGW), stud welding. carbon arc welding and atomic hydrogen welding. It is followed by Chapter 7, which gives a comprehensive accounts of resistance welding process. This presents resistance spot welding, resistance seam welding, upset welding, projection welding, percussion welding, and flash welding. Chapter 8 is on intense energy welding processes, which presents plasma arc welding, electron beam welding, laser beam, and welding.
