Lesson 02 - Casting Terminology

• Pattern: An approximate duplicate or true replica of required product of casting

• Flask/Box: The rigid metal or a wooden frame that holds the moulding material

• Cope: Top half of the moulding box

• Drag: Bottom half of the moulding box

• Core: As and shape that is inserted into a mould to produce internal features of a casting such as holes.

• Riser: A vertical opening in the mould

• Act as a vent for gases

• Helps to confirm that the mould is completely filled

• Act as a reservoir of molten metal to feed and compensate for shrinkage during solidification of a casting

• Gating System: Channels used to deliver the molten metal to the mould cavity

• Sprue: The vertical passage in the gating system

• Runner: The horizontal channel of the gating system

• Gate: Channel which connects runner and mould

Location: United States

Lesson 01 - What is Casting ?

Casting process is one of the earliest metal shaping techniques known to human being. • It means pouring molten metal into a refractory mold cavity and allows it to solidify. • The solidified object is taken out from the mold either by breaking or taking the mold apart. • The solidified object is called casting and the technique followed in method is known as casting process. Six basic steps in this process: • Place a pattern in sand to create a mold. • Incorporate the pattern and sand in a gating system. • Remove the pattern. • Fill the mold cavity with molten metal. • Allow the metal to cool. • Break away the sand mold and remove the casting

Lesson 04 - What is Pattern ?

What is pattern? • Pattern is the principal tool during the casting process. • A pattern is a model or the replica of the object (to be casted) • It may be defined as a model or form around which sand is packed to give rise to a cavity known as mold cavity in which when molten metal is poured, the result is the cast object. • A pattern prepares a mold cavity for the purpose of making a casting   Objective of a Pattern Pattern prepares a mould cavity for the purpose of making a casting. • Pattern possesses core prints which produces seats in form of extra recess for core placement in the mould. • It establishes the parting line and parting surfaces in the mould. • Runner, gates and riser may form a part of the pattern. • Properly constructed patterns minimize overall cost of the casting. • Pattern may help in establishing locating pins on the mould and therefore on the casting with a purpose to check the casting dimensions. • Properly made pattern having finished and smooth...

Lesson 03 - Advantages, Disadvantage & Application of Casting

Advantages of Casting • Product can be cast as one piece. • Very heavy and bulky parts can be manufactured • Metals difficult to be shaped by other manufacturing processes may be cast (Ex. Cast Iron) • Best for mass production • Complex shapes can be manufactured Disadvantages of Casting • Casting process is a labor intensive process • Not possible for high melting point metals • Dimensional accuracy, surface finish and the amount of defects depends on the casting  process • Allowances required Applications of Casting • Transportation vehicles(Ex. engines) • Machine tool structures. • Turbine vanes • Mill housing • Valves • Sanitary fittings • Agricultural parts • Construction &atomic energy applications.
