What is Sheet Metal Fabrication?
Sheet Metal Fabrication is a manufacturing method that involves cutting and bending sheets of metal to form different shapes. It is more cost-effective than CNC machining when it comes to metal components with uniform wall thickness.
Sheet Metal Fabrication Processes
1.Cutting
1)Laser cutting:
Applies a laser-focused light beam to cut through metal sheets. It can also be used for engraving sheet metals.
Allowable Sheet thickness: 1-10mm (depending on material)
2)Water jet cutting:
A high-velocity process that directs abrasive-concentrated streams of water at the sheet to cut into the material.
3)Plasma:
Plasma cutting uses heat-compressed ionized gases that travel at high speed and conduct electricity to direct cuts at a metal sheet.
Depending on the type of part to be manufactured, the complexity of the design and the desired finish, metal sheets may be formed in 3 simple steps namely cutting, forming, and joining (assembly).
2.Forming
Forming is the general umbrella for processes like stamping, stretching, roll-forming, and bending. Unlike cutting where the material is removed from sheet metal, forming simply uses fabrication tools to reshape the part to the desired geometry.
3.Bending
This manufacturing process can be done by hand or brake press, or used dies to produce a U-shape, V-shape or channel shape along a straight axis in ductile materials.
Allowable Sheet thickness: 1-6mm (depending on material)
4.Assembly
Assemble involves processes like riveting, adhesives, brazing, and most popularly, welding.
5.Welding
May be Stick, MIG, or TIG. The process essentially fuses two or more metal sheets by using a flame to melt them together in the presence of a filler.
6.Riveting
Joins sheet metals together by embedding small metal parts through both sheets.
