Which one of the following statements is correct?a)In extrusion proces...
Explanation:
In the extrusion process, a metal or alloy is forced through a die to create a desired shape with a continuous cross-section. The forming pressure applied during extrusion plays a crucial role in determining the thickness of the walls of the extruded product.
Thicker walls with increasing forming pressure:
When the forming pressure is increased during extrusion, it leads to a higher flow of material through the die. This increased flow results in a higher volume of material being pushed into the die cavity, which leads to thicker walls in the extruded product. Therefore, option 'A' is correct.
Other statements:
Let's evaluate the other statements to understand why they are incorrect.
b) Extrusion is an ideal process for obtaining rods from metal having poor density:
Extrusion is a process suitable for manufacturing products with a continuous cross-section, such as tubes, rods, and profiles. It is not specifically limited to metals with poor density. Therefore, option 'B' is incorrect.
c) As compared to roll forming, extruding speed is high:
Roll forming is a continuous bending process for forming sheet metal into desired shapes. The speed of the extrusion process can vary depending on various factors such as the complexity of the profile and the material being extruded. It is not necessarily higher or lower than roll forming. Therefore, option 'C' is incorrect.
d) Impact extrusion is quite similar to Hookers process including the flow of metal being in the same direction:
Impact extrusion and Hookers process are two different manufacturing processes. In impact extrusion, a punch strikes a metal slug to force it into a die cavity, forming the desired shape. In Hookers process, a metal billet is pressed through a conical die to form tapered tubes. The flow of metal in impact extrusion is radial, while in Hookers process, it is axial. Therefore, option 'D' is incorrect.
Conclusion:
The correct statement is option 'A' - In the extrusion process, thicker walls can be obtained by increasing the forming pressure.
