Metal is an element that is a good conductor of electricity and heat. Manufacturing metal that is formed into flat pieces is called sheet metal fabrication. These metal sheets can be bent into any shape that you desire and can be used in the manufacturing of several items. A metal sheet that is very thin (below 6mm) is called a foil or leaf. Anything thicker than 6mm is called a plate. United Global Sourcing specializes in sourcing fabricate sheet metal components. This process can convert Nickel, Aluminum, Brass, Bronze, Copper, Magnesium, Stainless Steel, Steel, Tin, Titanium, and Zinc to metal sheets.
Cutting, bending, and assembling metal is called metal sheet fabrication. The process for sheet metal fabrication includes:
a) Utilizing saws, shears or chisels for cutting the manufacturing metal. Both the manual as well as the powered variants can be used. Oxy-fuel torches or plasma torches or other similar torches may be used for the torching process. CNC cutters (using a laser, mill bits, torch, or water jet) are also used.
b) Manual as well as powered hammers are used for bending the metal. Press brakes can also be used for metal bending purposes.
c) After the pieces are cut and bent, they need to be assembled. This is done by welding, binding with adhesives, riveting and threaded fasteners. Typically for starting material for fabrication, structural steel or sheet metals are used. These are used in conjunction with welding wire, flux and fasteners. This process is done by our production facilities across Asia. What results from this process is called a fabrication.
The sheet metal fabrication process could be one of two categories.
- The forming process is one where the applied force causes the material to deform but not fail. This bends the sheet into the desired shape.
- The cutting process is one where the force causes the material to fail and separate, and it allows the material to be cut. In the process called shearing, shearing force is needed to cut the metal. Other cutting processes remove material by using heat or abrasion, instead of shearing forces.
Forming, Bending, Roll forming, Spinning, Deep Drawing, Stretch forming, Cutting with shear, Shearing, Blanking, Punching, Cutting without shear, Laser beam cutting, Plasma cutting and Water jet cutting are various types of methods we use in the process of fabrication.
Sheet metal fabrication involves cutting and burning the metal sheet using machines such as band saws to cut the sheet metal. These saws have special hardened blades and are capable of feeding the sheet metal to ensure that the cutting is even and consistent.
Hydraulic breaks are also used in the process of sheet metal fabrication. This creates bends at predetermined angles, thus simplifying the process of fabrication process.
After the metal parts are formed, they will need to be welded into place using one of many welding processes. These include using a stout fixture, welding in a staggered manner, and covering the metal with sand during the cooling process.
During the final step in the fabrication process, the metal is sand blasted, primed and then painted. Finishing touches are placed according to your specifications. The piece then goes through a rigorous inspection and is then prepared for shipment.
There are many advantages to the fabrication process. It helps in forming complex shapes. This allows for the use of several types of metals, thus leading to high production rates. Both lead time and labor cost is significantly lowered.
