Most metals used for industrial purposes are dense and hard. They are mined as ore, melted and refined to remove impurities, and solidified to achieve the hardness required by their intended applications. Sometimes, they are alloyed with other metals to create even stronger and more durable materials. How they are manufactured into bars, sheets, and modified shapes, however, is a completely different process, called metal forming.
Different Metal Forming Methods
Metal forming is the process of shaping metal through mechanical deformation. It doesn’t involve the use of chemicals, only high loads and stresses. There are two main categories: one is compressive forming in which the primary means of deformation is uniaxial or multiaxial compressive loading, and the other is tensile forming, which relies on pulling forces. Some specialized metalworking processes require a combination of both, while others require different versions of the force applied on them, including bending and shearing.
Of the two categories, compressive forming is the more commonly used one, as it can be performed in many ways, including rolling, extrusion, die forming, forging, and indenting. All of these techniques involve pressing metal with a heavy load to turn it into specific shapes. Among these compressive forming techniques, the most unique and particularly efficient is extrusion. Manufacturers in need of high production volumes in the shortest time possible should opt for this option. Read more from this article: http://bit.ly/2EUIXg7
