Forging is one of the oldest types of fabrication, with blacksmiths using forging centuries ago. Fab shops may use multiple fabrication processes to create a final product. The term also means a lie. Most solid components, such as gears, bolts, screws and nuts, are machined.

All Rights Reserved. In some cases, a vacuum is also used in this process. The end products of other common types of metalworking, such as machining, metal stamping, forging, and casting, may be similar in shape and function, but those processes are not classified as fabrication. Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. Many metal fabricators specialize in specific processes or metals. COVID-19 Response The sheared edges are usually burred. Fabrication is the process of making something from semi-finished or raw materials rather than from ready-made components. It is a value-added process involving the creation of machines, parts, and structures from various raw materials. Most punch presses are mechanical but smaller and simpler punches can be hand-powered. They may also provide finishing services such as deburring, polishing, coating, and painting, to the product. Cutting may be the first stage in a longer fabrication process or the only process used. For example, if I say “John’s story about the elephant was a fabrication,” I mean that it was a lie. Fabrication comprises or overlaps with various metalworking specialties: Standard metal fabrication materials are: A variety of tools are used to cut raw material. Common custom metal fabrication processes are as follows: 1. Fab shops generally have some machining capability, using metal lathes, mills, drills, and other portable machining tools. Tungsten Inert Gas Welding (TIG), also called Gas Tungsten Arc Welding, uses a tungsten electrode rod that creates a short arc to weld heavier metals, for heavy fabrication. Die cutting is another cutting process that uses a die to slice metal. This process is usually used to shape sheet metal. Terms and Conditions, Start here, where we have over 9,000 Fabricators listed in our Database. Burn tables are CNC (computer-operated) cutting torches, usually powered by natural gas. Fabrication process It is a secondary manufacturing process. Permanent mold casting can create stronger castings than die casting, but they can be difficult to remove from the final product. When enough force is applied to the appropriate metal, it starts to flow into the available shape, much like the movement of viscous liquid. This method is more portable than MIG or Stick welding but can’t be used on thinner metals. Specialized metal fabricators are called fab shops. The drill bit presses against the metal while being rotated very quickly in order to create a circular hole. If a company manufactures a wide range of products that can be modified based on the customers' requirements, then a custom manufacturing process is a good fit. By using this site, you agree to our. Die-casting is when liquid metal is forced into a die instead of a mold, and there the applied pressure keeps it in place until it hardens. After the weldment has cooled, it is generally sandblasted, primed and painted. The shielding gas also creates less welding fumes. The end product can either be the piece of metal with holes for fastening purposes, or it can be the now removed, and shaped metal pieces called the blanking. Some of the most popular metal types available for custom metal fabrication include aluminum, brass, copper, gold, iron, nickel, silver, magnesium, tin, titanium, and various grades of steel.

Common custom metal fabrication processes are as follows: Casting is when molten metal is poured a mold or die and allowed to cool and harden into the desired shape. Drawing 4. Stamping 11. These may include redesigning the piece to require less welding, employing staggered welding, using a stout fixture, covering the weldment in sand as it cools, and post-weld straightening. Manufacturing is the process of converting raw materials into a finished product, by means of large-scale industrial operations. Fabrication is used for both custom and stock products. COVID-19 Response: Source manufacturers & distributors providing COVID-19 medical supplies Some of the work may be sub-contracted out depending on the size and specialized needs of the project. Choosing a custom metal fabrication shop or custom metal manufacturer that will best fulfill a project’s needs is an important decision that can affect the manufacturing rate, production quality, and cost-effectiveness of a given project. One long, straight cut is achieved by combining two tools, with one of the tools above the metal and other one located below for applying pressure. See Flatbed die cutting is used on thicker metal materials and uses a dies on a press to cut out shapes when the die stamps down on the metal. This very common type of fabrication is the cutting of a metal workpiece to split it into smaller sections. Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses an electrode stick that produces an electric current that forms an electric arc when in contact with metal.
