1 Answer

Answer :

Advantages of Forging:

1. Strength:

i. Forging reduces the failures.

ii. High strength to weight ratio.

iii. It can be able to withstand fluctuating stress caused by sudden shock loading.

2. Metal Conservation:

i. Practically there is no waste of metals.

3. Weight Saving:

i. Strong thin-walled parts may be produced without damaging important physical requirements.

4. Machining Time:

i. Reduces machining time for finishing operations of the products.

5. Speed of Production:

i. High rate of production is possible.

6. Incorporation in Welded Structures:

i. Parts can be welded easily due to fibrous structure.

7. It maintains uniform and same quality all over parts

8. It gives close tolerances.

9. It gives smooth surface finish.

10. Allows the metal to be displaced where it is needed.

11. Minimum machine finish carried out on the components especially when it is forged in dies.


Limitations of Forging:

1. High tool cost.

2. High tool maintenance

3. No cord holes.

4. Limitation in size and shape.

5. Heat treatment process increases cost of the product.

6. Brittle materials like cast iron cannot be forged.

7. Complex shape cannot be produced by forging.

8. Rapid oxidation of metal surface at high temperature wears the dies.
