The metal extrusion process is generally used for producing

A Uniform solid sections
B Uniform hollow sections
C Uniform solid and hollow sections
D Varying solid and hollow sections

Correct Answer: Uniform solid and hollow sections

The metal extrusion process is generally used for producing uniform solid and hollow sections.
Extrusion is a process used to create objects of a fixed cross-sectional profile.
A material is pushed through a die of the desired cross-section.
The extrusion process can be done with the material hot or cold.
