Syllabus
Introduction: Casting as a process of Manufacturing. Moulding Processes, Equipments and Mechanization: Different types of Moulds, Moulding Materials and Moulding processes, Pattern and other mould making equipments, forces acting on moulds, Mould factors in metal flow, Moulding factors in casting design. Different types of binders and their uses in mould and core-makings.
Melting of Metals and Alloys for casting: Brief mention of various melting units, melting and post melting treatments, melting practices as adopted for a few metals and alloys such as CI, Al, Cu, steels, cast irons. Solidification of Metals and Alloys: Nucleation, Growth, Role of alloy constitution, Thermal
conditions and inherent nucleation and growth conditions in the liquid melt, Significance and practical control of cast
structure
Principles of Gating and Risering: Feeding characteristics of alloys, Types of Gates and Risers, Time of solidification and
Chowrinov rule, Wlodawer system for feeder head calculations, gating ratio, concept of directionality in solidification,
Yield of casting and prescription for its augmentation. Special casting Methods: Investment casting, Die casting,
Centrifugal casting, Full mould casting, Vacuum sealed casting. Casting Defects: A detailed analysis of casting defects.
Their causes and prescription of remedial measures.
