Q1. Different between Forgings and casting
Ans. 
Forging involves shaping metal through compression, while casting involves pouring molten metal into a mold.
• Forging involves shaping metal through compressive forces, while casting involves pouring molten metal into a mold to solidify.

• Forging typically results in stronger and more durable parts compared to casting.

• Forging is a more precise process that allows for tighter tolerances, while casting is more suitable for c...read more

Q2. What is the forgings
Ans. 
Forgings are metal components that are shaped by compressive forces, typically through hammering or pressing.
• Forgings are typically stronger and more reliable than castings or machined parts.

• Common forging processes include open-die forging, closed-die forging, and ring rolling.

• Examples of forged components include crankshafts, connecting rods, and gears.

• Forgings are often used in industries such as automotive, aerospa

Q4. Process in casting
Ans. 
Process in casting involves pouring molten metal into a mold to create a desired shape.
• Mold preparation is crucial for successful casting

• Molten metal is poured into the mold cavity

Q5. Process in forging
Ans. 
Forging is a manufacturing process where metal is shaped by applying compressive forces using a hammer or press.
• Metal is heated to a high temperature to make it more malleable

• The metal is then placed on a die and struck with a hammer or pressed to shape it

• Forging can be done using different techniques like open-die forging, closed-die forging, and impression-die forging
