Extrusion and Rolling the first year engineer

Basics of Rolling. Let’s move onto rolling. Rolling is a similar mechanism to forging but instead of striking the piece with a press or hammer, the piece is rolled through, well, rolls. Rolls are just cylinders that force the material to become a certain shape. You know what baseball pitching machines look like? It’s basically that.
