Question

Question-3a: Describe the metal metal extrusion and plastic extrusion (two each) extrusion process. Write some similarities and dissimilarities between mechanical properties of metallic materials; which make some metals suitable for extrusion process alls so that its thickness is reduced by an
Please solve it in easy way easy to understand

Answer 1

Metal extrusion process is a metal forming process in that a work piece, of a certain length and cross section, is made to pass forcefully through a die of a smaller cross sectional area, thus forming the work to the new cross section.

Similarities

1. Both the processes are very capable to produce complex intricate parts.

2. In both processes , the scrap can be recycled reducing waste.

Dissimillarities

1.Cost reduction : Replacing metal parts with plastic can deliver a number of other benefits on top of lower manufacturing costs

2. Ease of coloring : With plastic components, colored polymers are used in place of painting or powder coating, creating significant time savings.

b.) The mechanical properties are as follows:

Good strength, better flowability of metals, Ductility
