Metal fabrication is a process in which metals were fabricated in order to create products such as hand tools, bolts, nuts, screws, pipes, and cans. But before achieving this product, the metals have undergone many processes such as molding, cutting, and shaping metal materials in order to create a final product such as machinery. Usually, metal fabrication shops or companies create products from raw materials instead of creating a final product that is assembled from ready-made materials. Upon performing metal fabrication, casting, drawing, folding, forging, machining, punching, welding, and more.
TYPES OF METAL FABRICATION PROCESSES
1. Casting – is a process in which molten metal is poured in a molder. After pouring the molten metal in the molder, the metal fabricator let it cool for a few minutes in order to harden the metal into its desired formation. By reusing the same molder, mass production of metal parts will be easier to create.
2. Cutting – is a type of fabrication process in which cutting of metal workpiece is done in order to turn apart pieces of metals. In the past, sawing was an old method of cutting. But now, modern methods of cutting were used such as plasma arc cutting, water jet cutting, power scissors, and laser cutting.
3. Drawing – is a process in which force is used in order to pull metal into and through a tapered die. The die then stretches the metal into a thinner shape. Drawing is usually performed at room temperature which is referred to as cold drawing. But in order to reduce the required force, the metal workpiece is heated.
4. Folding – is a process of metal fabrication in which the metal was bent through a hammer until it bends to the desired shape that we want. In addition, we could also use a folding machine, called a folder. Through using this machine, the sheet metal was placed to a flat surface and the clamping bar then holds the piece of machine in place. After that, a front panel lifts the metal upward that forces the workpiece to extend.
5. Forging – is a metal fabrication process that uses force in order to shape the metal piece. During this process, a hammer then strikes the metal until the proposed shape is formed. There were three (3) types of forging process. These are the cold forging, warm forging, and hot forging. Cold forging is done when the metal is at a low temperature. Warm forging is performed with the metal heated from high temperature to below temperature recrystallization. Hot forging is when the metal is heated to a high temperature or if it reaches to recrystallization.
6. Machining – is a process of shaping metals by removing unwanted materials from it. This process can be performed in many different ways such as drilling, turning, and milling.
7. Punching – is a process in which turrets that are uniquely shaped on a pressing punch that hits the metal into a molder or through it in order to create holes in it. The final product can be a piece of metal with holes for the purpose of fastening, or maybe removed, and shaping the metal parts which is usually called the blanking.
8. Welding – is a type of fabrication process in which two or more pieces of metals are combined together using heat and pressure.
Nowadays, there were many companies or fabrication shops that exist which offer services like metal fabrication. So if you are engaged in businesses that need machinery or metal products, you can visit the shop of Machining Austin TX and make business deals with them at an affordable price.
