Rationale:
Engineering and Non -engineering applications requires components made up of materials with required properties. There are various manufacturing processes available to produce components. Casting is the most important manufacturing process producing most of the Industrial and Automobile components. It is a very basic subject and should be studied.
It is a process which produces components in a large scale at economic price with Uni- Directional Properties. This subject deals with various basic requirements for Casting Process. It also deals various Moulding processes and some Important Special Casting Methods. The Common defects that may occur during casting process and their remedies are also included.
Objectives:
At the end of the study of V Semester the student will be able to
- Learn advantages & limitations of casting process over other manufacturing processes.
- Learn about basic tools for making mould cavity.
- Learn about mould making materials, ingredients and their properties.
- Learn about moulds and moulding processes and methods.
- Learn about mould properties and mould coatings.
- Learn about objectives, types and basic principles of designing gating systems.
- Learn about objectives, types and basic principles of designing risering systems.
- Learn about methods used for making intricate castings.
- Learn about finishing operations of castings.
- Learn about causes and remedies for defects.
- Learn about methods for salvaging defective castings.
