How To Make Laser Cut Metal SignsVIDEO ON THE TOPIC: Evolution EVOSAW355 - First Time User
No worries. Just let me know where to send it takes 5 seconds :. As the global metal fabrication market continues to experience exponential growth in the past couple of years, demand for steel, aluminum, and other metal products in major industries are also expected to increase.
Formed by about 51, companies, the fabricated metal product manufacturing industry in the U. Companies in the U. Metal fabrication is the creation of metal parts, structures, and machines from various raw materials by cutting, bending, and assembling process. Metal fabrication is a crucial step in the manufacturing process. However, it is often a misunderstood trade. Most people think it is the same as welding fabrication, which is only one of the many methods fabrication shops use.
Most mass-produced fabricated metal items like cans, pipes, bolts, and cutlery have a wider tolerance for error. This means each product may vary in minute details from the original design but still acceptable and functional. Sheet metal fabrication uses sheet metal to build structures and machines.
Businesses specializing in sheet metal fabrication are often called fabrication shops, or fab shops for short. Some tools used in sheet metal fabrication may include a rolling machine, plasma machine, band saw, hydraulic brake, and sandblasting machine, among many others. Precision sheet metal fabrication is the process of forming sheet metals into finished products. Medical, aerospace, automobile, electronics, and military industries all depend on precision sheet metal fabrication. Precision sheet metal fabrication subjects a sheet metal into annealing, bending, mechanical working, press forming, or roll forming to create the desired shape.
To make that into a finished product, the shaped sheet metal goes through cutting, drilling, sawing, shearing, or stamping to achieve the finished product. Finishing processes of precision sheet metal fabrication include deburring, painting the product, or sanding. Some of the most common products of precision sheet metal fabrication include storage enclosures, mobile carts, tanks, and ventilation systems. Sheet metal ductwork fabrication involves building ducts, usually for HVAC systems. Some tools to create sheet metal ducts include a plasma machine, lock former machine, hydraulic notching machine, power break machine, hand brake machine, and cleat former machine.
Products of sheet metal ductwork fabrication include plenum boxes, drain pans, duct mate, straight ducts, grease ducts, and trunk ducts. HVAC sheet metal fabrication is a subcategory of precision sheet metal fabrication. It is imperative to meet all industry standards, particularly for industry ductwork. This is because ductwork may carry huge amounts of boiling or dusty air throughout the HVAC system. This air may reach temperatures as high as 1, degrees Fahrenheit degrees Celsius.
Having quality ductwork ensures that the air reaches its destination in the safest way possible. Sheet metal duct fabrication for indoor air distribution use varying gauges. But mostly they are rectangular or circular in shape. Trunk ducts carry the conditioned air from the air handler out to the plenum from which branch ducts distribute to individual air distribution outlets.
The sheet metal thickness for trunk ducts varies in gauges, either 26, 28, or Plenum ducts serve as a collector box that is directly attached to the supply outlet of an HVAC system. Plenum ducts vary in sizes. Overall, sheet metal ducts usually come in 3-feet lengths for easy handling. One end of each piece is crimped to fit well with consecutive joints. The seams are mostly formed on a snap-lock machine to make it easy to assemble. Custom metal fabrication often involves stock metal components, such as sheet metal, metal bars, metal billets, and metal rods, to create a new product.
For instance, a metal billet may be fabricated into a curve metal tube by using extrusion and folding the tube. Some of the most popular types of metal used in custom metal fabrication include steel, aluminum, brass, copper, and titanium.
Before a finished custom sheet metal fabrication product is handed over to the customer, it has to go through a series of sheet metal fabrication processes and tools, depending on the application it serves. The goal is to convert a metal sheet into a workable item. The custom sheet metal fabrication process includes blanking, bending and forming, assembly, or finishing.
Some tools used in custom sheet metal fabrication include a turret press, water jet cutting machine, folding machines, press brakes, stamping units, and fiber optic laser cutting machine. Metal fabrication is too broad of a term that refers to any process involving cutting, shaping, and molding.
There are so many processes involved in metal fabrication, and they vary in mechanism and tools to use. But, at the end of the goal, the goal is the same—to produce parts or assemble components to make a finished product. To learn more about the processes in metal fabrication, here are 12 of the most common techniques used to fabricate a metal product.
Cutting is the most common metal fabrication process where sheets of metal are cut into smaller parts. In most applications, the metal being cut is freshly manufactured and has yet to be made into anything in particular. In other applications, pre-shaped metals like panels and bars are subjected to cutting.
Some cutting machines include lasers and plasma torches, power scissors, waterjet cutting machines, and CNC machines, among others. Drawing requires tensile force to pull metal into and through a tapered die. The die expands the metals into a thinner shape. The drawn metal can be heated to lessen the required force. The process is called deep drawing when the finished product has a depth that is equal to or greater than its radius. For instance, hollow cylindrical or box-shaped vessels drawn from a sheet of metal.
Forging employs compressive force to shape metal and often achieved using a hammer or die. Forging is one of the oldest forms of metal fabrication which has been used for centuries.
Metal forging can either be done at room temperature cold forging , above room temperature to below the recrystallization temperature warm forging or above recrystallization temperature hot forging. Folding is a complicated metal fabrication process whereby the metal surface is manipulated to bend at a certain angle using folding. It can be done using a brake press, hammer, or the folder machine.
Welding fabrication is another popular metal fabrication techniques. This process involves joining or cutting two metal parts using a welding machine. The metal parts could be metal sheets, panels, bars, or whatnots.
Extrusion uses force through and around an open or closed die to reduce the diameter of the metal piece to the cross-section of the die. When pressed around a die, the metal piece gets a cavity within. Extrusion uses a metal slug billet as the workpiece and a ram to strike it. The finished product is often used for wiring or piping. It can be long or short pieces. Cold extrusion is done at room temperature, and it is often used for steel fabrication, including stainless steel fabrication.
On the other hand, hot extrusion is done at high room temperature to prevent the metal from hardening. Hot extrusion is often used for copper fabrication. Machining is used to remove parts from a piece of metal.
It is usually performed on a lathe. In other machining applications, a hole or set of holes are formed directly through the metal surface. Machining can be done by drilling, turning, and milling. Drilling uses a rotary cutting tool called drill bit to punch a hole. Turning uses a lathe to rotate the metal while a cutting tool moves in a linear motion to remove metal along the diameter, making a cylindrical shape.
Lastly, milling uses rotating multi-point cutting tools to remove materials from the workpiece until the desired shape is achieved. Punching creates holes in a workpiece by placing it under a die and punching it through using a drill. A CNC punch press is a common tool used here. Shearing involves long cuts. In most applications, the sheet is loaded through a metal-cutting machine. In other applications, the sheet is cut using a cutting tool. Shearing is often applied to trim down the edges of a metal sheet.
Stamping is the process of making tiny humps protruding on the metal sheet. Like punching, it uses a die, except that the punching process does not penetrate to avoid making a hole.
Metal stamping is often seen on coins. Casting is another ancient process of metal fabrication. It involves molten metal poured into a mold to form something. The most common metals used in casting include steel, iron, gold, copper, silver, and magnesium. Techniques for metal fabrication vary in complexity with respect to the desired qualities of the finished product and the composition of the materials in use.
Hardness, strength, conductivity, and resistance to corrosion are all commonly sought after qualities. Through different methods in cutting, bending, and welding, these metals can be used in a multitude of products ranging from toys and appliances to larger structures like ductwork, furnaces, and heavy machinery. In this section, let us explore the different types of metal fabrication according to the materials used, including steel fabrication and aluminum fabrication.
Steel fabrication involves the use of steel—an alloy of iron and carbon—and is the most common material used in metal fabrication. Its endless range of products includes construction materials, weaponry, and machinery.
Steel is most difficult to cut and so it requires a fairly extensive fabrication process.
