What is metal fabrication?
Before explaining about aluminium fabrication, lets first discuss metal fabrication. Metal fabrication is the creation of machines and metal structures from raw metal materials. This process is carried out by cutting, burning, welding, machining, forming and assembly to create the final product.
Everything from hand railings to heavy equipment and machinery production all come under metal fabrication. Other subset features include cutlery and hand tools, structural and architectural, hardware manufacturing, wire and spring manufacturing, forging, stamping and bolt construction.
Types of Fabrication
Metal fabrication is done for a wide range of industries and applications. Metal fabricated parts include everything from car parts, aircraft components, boat propellers, holding tanks, shark cages, weapons, and much much more.
Everything you see around, from safety pins to high build machines are all done by manipulating one thing to something else, i.e. metal fabrication.
There a wide range of industrial applications and several fabrication processes such as
The first stage of fabrication is cutting, and the saw does the traditional cutting, modern cutting techniques include laser, plasma and waterjet cutting, numerical control, chiselling, and shearing. To implement which method to use depends on complexity and cost.
Press Brake is being used for the folding process. Metal parts need to be bent accordingly to create individual steel sections, and this is done through press brake. Press brake has a set of dies which compresses the metal to produce a fold. Programming software is now implemented to make press brakes more efficient. Usage of press brake is infrequent, and it depends on the shape of dies and shape of the part.
Machining is the process of shaping of materials to obtain required shape demanded by the customer, i.e. removal of unwanted substances from the metal. This process is done on a lathe or drill and involves various other sub-processes. In case of a lathe, the material revolves against the cutting tool, and if it is drill, the rotating mechanism is moved in multiple ways against the fixed piece.
Punching is the process where the metal is punched to create a hole in it. Punching process uses a punch and a die. Punch and die must be of same size and shape as the required hole. Holes are made for the idea of fastening, or that removed portion might be the required product called blanking.
Shearing is also known as die-cutting is the process used to cut straight lines on the flat metal sheet. This process is done with an upper and lower blade made to pass each other with a space between them determined by the desired offset.
The stamping process is similar to the operation of punching, except that in stamping no cut is made. The die is moulded in a way that causes the material to be raised instead of penetrating the metal.
Welding is the process of connecting two metals to form the desired steel section or build a massive structure. There are various welding methods used for different applications such as laser beam welding, and commonly used weldings are MIG, TIG, Stick and Flux-Coredd arc welding.
Aluminium is the third most abundant element on this planet. Therefore, there is an enormous availability of aluminium. Aluminium also contains many other features such as
- Aluminium is a Lightweight metal with 2.7 g/cm
- Aluminium can blend well with other metals.
- Aluminium is an excellent conductor of heat and electricity, and it is not at all affected by magnetic fields.
- Aluminium is also an excellent sound absorber, thus used in house construction and in automobiles to absorb sound.
Thus Aluminium increases the malleability, strength and corrosion resistance and so on.Nowadays, Aluminium fabrication is used in a wide array of industries. Aluminium metal is preferred for its superb properties which are mentioned above, such as excellent strength, durability, non-ferric metal and ability to blend with other metals combined with lightness. Aluminium fabrication is the manipulation of aluminium metal into another element. And aluminium fabrication process involves the above-mentioned process such as cutting, bending, assembly and welding. Aluminium fabrication does not include moulding and metal melting.Thus, aluminium fabrication is used for the production of all kinds of support structures such as doors, windows, rails, partitions, scaffolds and architectural accents. Various accessories and fittings such as Locks, ladders are also made from it, since aluminium is a light material which in turn assemble quickly and also for its weather resistance and ability to not scratch or band. The fabricated items are durable, light and reliable. Since aluminium shows high resistance to water and ultraviolet radiation, this feature is highly valued. This metal is the approved choice for the manufacture of automobiles and aircraft, in particular, as it provides for lighter weight and the reaching of higher speed. At present, there are even all-aluminium automobiles accessible to the general public.
