Sheet Metal

The manufacturing method that involves cutting and bending sheets of metal to form different shapes, popularity material is aluminum

More cost-effective than CNC machining when it comes to metal parts with uniform wall thickness

Sheet Metal Fabricate Service

Sheet metal can be deformed in many ways, i.e. it can be welded, bend, punched or cut. Besides, a wide variety of shapes can be made from sheet metal. 

In fact, sheet metal fabrication is more cost-effective choice for metal components with uniform wall thickness. 

Available materials for sheet metal

Generally,sheet metal has a rectangular shape. It is also characteristic that the thickness of a sheet is considerably below that of its length and width.

In addition to steel, numerous other metals such as copper, aluminum and gold as well as brass alloys can be processed into sheet metal. In order to be processed into sheet metal, however, the materials used should have specific characteristics, i.e. a certain toughness and rigidity, and of course be ductile, i.e. formable. These requirements result in restrictions with regard to the materials that can be used. Thus, it is not possible to process very brittle or extremely stiff materials into sheet metal. Below is a list of typical materials for sheet metal fabrication

Carbon steel

Stainless steel

Aluminum

Copper alloys

1018 steel

SUS304

5052

C101

 

SUS316L

5083

 

Available sheet metal fabrication processes

In addition to welding, cutting and bending, the processes of sheet metal processing also include punching, forming, rolling and joining. 

▶  Laser Cutting

Highly accurate, capable of cutting dissimilar thicknesses at the same time, low heat-affected zone, and able to cut hole diameters under half a material thickness.

▶  Bending

Forms generally uniform-thickness material to a specific shape or angle along a straight axis.

Name

Processing

Allowable sheet thickness

Laser cutting

Uses a high-power laser beam to cut a material sheet.

< 10mm (depending on material)

Bending

Uses dies to produce a U-shape,
V- shape or channel shape along
a straight axis in ductile materials.

< 10mm (depending on material)

Sheet Metal Surface Treatment

Different methods can be used to carry out a surface treatment in sheet metal processing. The surface treatments in metalworking are therefore allocated to different process classes, which are the following:

  • Surface removal (electropolishing, burnishing)
  • Surface coating (chrome plating, powder coating, painting)
  • Mechanical surface treatment (shot peening, polishing, grinding)
  • Chemical surface treatment (pickling, degreasing, cleaning)

Polishing

Powder Coating

Anodizing

Chrome plating

Sandblasting

Brushed(Burnishing)

Electropolishing
