Question

1. in which process the cross section of the metal is reduced by forcing it to fiow through
a die under high pressure?
a) Forging
b) Forming
c) Extrusion
d) Welding​

Answer 1

Answer:

C Extrusion

Explanation:

Extrusion is a process that uses a die in order to get a material with a constant cross-sectional cut. The die is what the material is pushed through in order to get the desired shape.

Answer 2

Answer:

Extrusion is a process in which cross section of the metal is reduced by forcing it to flow through a high pressure.

Explanation:

• Using a die, the extrusion process produces a material with a consistent cross-sectional cut. The material is forced through the die to achieve the required form.
• Each product uses a unique die to produce that shape and feature. Materials including plastic, aluminium, and bread are extruded.
• Extrusion is required to form the desired shapes since these items are either too brittle or too soft to be bent or hammered into the desired shapes.
