Question

Match the products to be manufactured with the given metal working processes. 

• A. P – 3, Q – 4, R – 1, S – 2
• B. P – 4, Q – 3, R – 1, S – 2
• C. P – 4, Q – 3, R – 2, S – 1
• D. P – 4, Q – 3, R – 1, S – 2

Hint:

Deep drawing is used for hollow components like beverage cans, while extrusion is used for forming continuous shapes like pipes. Forging and skew rolling are used for shaping solid metal components like connecting rods and steel balls.

Answer 1

The Correct Option is D

- P – Beverage can: The process used for manufacturing beverage cans is deep drawing. This is a sheet metal forming process where a blank metal sheet is drawn into a cup shape.
- Q – Seamless pipe: The process for manufacturing seamless pipes is extrusion. In extrusion, a material is forced through a die to form the desired shape.
- R – Connecting rod: The forging process is used for manufacturing connecting rods. It involves shaping metal using compressive forces.
- S – Steel balls for bearing: Steel balls are typically made using skew rolling, a process involving rollers that deform metal into a cylindrical shape and then cut it into individual balls. Thus, the correct match is P – 4, Q – 3, R – 1, S – 2.
