Metal Casting

Metal Casting. Instructor: Dr. D. B. Karunakar, Department of Mechanical and Industrial Engineering, IIT Roorkee. This course is an elective subject for manufacturing students. The subject comprises a little wider and deeper on the manufacturing techniques by casting process. It covers bigger spectrum for manufacture products by the casting techniques with required attributes specified for certain purpose such as intricacy, features detail, soundness and others. Among topics or issues include in this course are liquid metals, solidification, molding material, casting design, production techniques, Metal melting and treatment, and casting quality and evaluation.
