Knowing the Different Stages of Metal Fabrication

Feb 6

Steel is unquestionably one of the most widely used building and manufacturing alloys on the planet. It's a multifunctional product that combines durability, cost-effectiveness, and workability. Metal structures are created by cutting, manipulating, and assembling metal elements. Metal fabrication is used to manufacture automobile frames, building panels, roofing, and plane fuselage panels, among other things. Seek the services of a sheet metal fabrication firm if you require parts for a machine or other product. These organizations can shape metal sheets into parts that are customized to your specifications using a variety of ways.

What is Metal Fabrication?

The process of fabricating metal pieces or structures from raw metal resources is known as metal fabrication. In the overall production process of metal items, a variety of fabrication processes such as cutting, punching, bending, and welding are used. Metal fabrication is used by virtually every business to run efficiently, make tools, develop goods, and so on. As you can see, it is a very large industry that contributes to the smooth operation of the entire world. It's good to know what kind of processes are involved with metal fabrication. Let's find out together below! 


Engineers frequently create drawings or blueprints of the item to be created before beginning the metal fabrication process. This is a critical stage in the manufacturing process since it allows engineers to discover any issues with the product design and make any necessary changes before using materials. While some fabricators still utilize hand-drawn designs, which might be suitable for simple tasks, most modern engineers use CAD (computer-aided design) software like AutoCAD. As they design and test models to exact specifications, CAD enables higher complexity and perfect precision. Metal laser cutting often necessitates the use of digital CAD files. 


After the design has been formalized, the programming phase converts the designs into a language that the machinery that creates the products can understand. Parts are sketched and then "layered in 2D form onto a metal sheet in order to maximize material utilization.


Plate and sheet metal can be cut in a variety of ways. Precision cuts for all types of metal can be achieved via laser cutting, mechanical shearing, or water jet cutting. Any metalworking project has a very limited tolerance for mistakes, therefore picking the proper procedure for cutting plate and sheet metal is crucial. Shearing is the best way to cut a huge sheet into smaller rectangles. The shearing machine, which looks like a big pair of scissors, has a long blade that produces a straight cut through the sheet. We frequently use laser cutting to cut out more complex shapes.


Metal fabrication companies must bend raw metal after cutting it. After cutting metal, there are a variety of techniques to bend it. Metal sheets or sections are hammered into the desired shape by some metal fabrication companies. Hammering can be done manually or with the help of a machine (power hammering). Many metal fabrication companies, however, have recently started using press brakes to bend their metal. When this massive industrial machine is turned on, it automatically forms metal sheets and pieces into a precise shape. It clamps the metal between two punch dies and forces it into the required shape. Sheet metal can be strengthened by bending, and it can also be used to reduce sharp edges. It can sometimes result in metal thinning, but this is not always the case.


Assembling is the third and last step in the metal production process. This procedure entails assembling the metal sheet or parts into the desired completed product, as the name implies. After the metal parts have been shaped into the correct shape, the finished product must be assembled into the proper arrangement. The individual parts are assembled and held in place by clamps until they are fused together. The parts are then bonded, screwed, riveted, or, most commonly, welded together.


Most fabrications are finished after they have been assembled or joined. Protective coatings, such as rust-resistant paint, colour, or glazes, are applied in the last process, either by painting or powder coating. This includes everything from cleaning welds to polishing them to a mirror shine (like truck bumpers.) There are a variety of painting and coating possibilities in between those two extremes. These normally serve two purposes: to protect the fabrication against corrosion and to produce the desired completed appearance.
