Advantages Of Casting Process
Casting has the following advantages over other manufacturing processes.
● It can create any complex structure economically.
● The size of object doesn’t matter for casting.
● The casting objects have high compressive strength.
● All structure made by casting has wide range of properties.
● This can create an accurate object.
● All material can be cast.
● It creates isotropic structure.
● It is cheapest among all manufacturing processes.
● Composite component can be easily made by casting.
Disadvantages Of Casting Process
The disadvantages of the Casting Process are as follows.
● Dimensional accuracy: Because of shrinkage in the casting, the dimensional accuracy might be at risk. So, the designers must take care of providing the allowance to the product (Pattern) before pouring the molten metal.
● Low strength: Due to high porosity compared to a machined part.
● Post-processing: It requires Secondary machining operations in order to improve the surface finish.
● Lower Melting Point: Generally limited to metals of the lower melting point.
Not suitable for low-volume production.
