Unit I- Casting Processes
1 What is Riser in casting? Explain Design of Riser in casting
2 A Cylindrical riser must be designed for sand casting mould. The size of the steel casting is
60mm X 120mX20mm.The precious observations have indicated that the total solidification
time for casting is 90 sec. The cylindrical riser has (d/h)=1.Find the size of the riser so that
its total solidification time is 130 sec.
3 Explain Different types of cores used in foundry with neat sketch
4 Explain Jolt Moulding Machine
5 Discuss Gating system with its elements draw suitable sketch, What are the functions of an
ideal Gating system?
6 Explain Porosity test of moulding sand
7 A cylindrical riser must be designed for sand casting mold. The size of steel casting is 75
mmX125mmX20 mm.The observation done earlier have indicated that the total solification
time for casting is 90 sec. The cylindrical riser has (d/h)=1.Find the size of the riser so that
its total solidification time is 120 sec.
8 Differentiate between hot chamber and cold chamber die casting with neat sketch
9 What is Cold Chamber Die Casting? Explain With Neat Sketch
10 What are different defects in casting Explain with neat sketch
11 Explain Centrifugal Casting with neat Sketch
12 Explain Moisture content test for moulding sand
13 Explain Properties of Moulding Sand
14 Cylindrical Riser must be designed for a sand casting mould.The size of steel casting is 40
mm X 100 mm X 10 mm.The previous observations have indicated that the total
solidification time for casting is 80 seconds.The cylindrical riser have d/h=1 Find the size
of riser so that total solidification time is 120 sec.
15 Explain Centrifugal casting with neat sketch
16 Using Chvorinov’s Rule, find the ratio of solidification time for cube shape casting to a
sphere shape casting. The volume of cube shape casing having side ‘a’ and sphere shaped
casting having radius ‘r’ is 1000 cm3 Assume Value of mould constant is same for both
castings
