About the Examination:

Punjab Technical University offers a large number of higher courses to the candidates. M.Tech in Production Engineering is amongst one of them. There are different papers are set according to the duration of the course. Metal casting papers is one of the important parts of the production engineering.

About The Paper:

The Metal Casting Papers of Production Engineering is included in the syllabus in order to give the complete knowledge about the die-casting, moulding, welding and analysis of the different properties of alloys. The paper

Important syllabus topics:

With most efficient and subjection types of knowledge is required to crack this examination. The most important topics pointed out from its syllabus are different mechanism and types of clays, structural properties from first few sections. Just next to these are about metals, alloys, moulding and its related properties. The candidates also have to focus on the analysis and scaling of metals, die-casting of bronze, aluminum etc.

Time allotted and full marks of this Paper:

Candidates are restricted to complete the total part of the question within three hours. The M.Tech in Production Engineering Metal Casting Papers includes a total of 100 marks. Candidates must have to maintain the discipline and also have to follow all sorts of information provided in the question papers.

Syllabus of the Paper:

Features of Casting problems, Solidification of actual casting, Progressive and directional solidification, Centreline, Survey and Scope of Foundry Industry, Solidification of pure metals, Nucleation and growth in alloys, Effects of gates on aspiration, Turbulence and

dross trap, recent trends, feeding resistance, Rate of solidification, Chvorinov’s rule, Electrical analog of solidification problems. Melting and Fluidity: Selection and control of melting furnaces; molting, refining and pouring; Coupla design.

Gating and Risering Systems: Gating systems and their characteristics, Feeding distance, Risering of complex casting, Riser design, Risering curves, NRL method of riser design, Risering of alloys other than steel, Riser design by geometrical programming.

High pressure moulding, Full mould process, Flaskless moulding, Moulding and Core Making: Review and critical comparison of various established processes, recent developments e.g. low pressure and ferrous die casting, Continuous casting, Hot and cold box moulding, Ceramic shell moulding, V-process, Squeeze and pressed casting, Nishiyama process, Shaw process, Anitoch process, etc.

Measurement of fluidity, Effect of various parameters on fluidity, Internal Stress, Defects and Surface Finish: Residual stresses, Hot tears and cracks in casting; Stress relief, Methods of elimination and control of gases in casting, efects and their causes and remedies; Parameters affecting surface finish and related defects e.g., Rough casting, bum-on sand bum-in metal penetration, Facing and washes; Mold wall movement; transport zones, Expansion scabbing etc. Casting of Sand, Design Considerations: Recent developments, e.g., Mulling index; Mouldability index, Compactability, deformability etc.

Paper pattern:

Production Engineering Metal Casting Papers set is equally separated in different sections of questions with its sub groups. The questions are generally little tricky and sort of descriptive types. The questions pattern is mainly consisted of equal numbers. The candidates are asked to follow all sorts of instruction mention in the question papers.
