Forming Sheet Metal
During the manufacturing process, sheet metal is typically first
punched and cut using various methods, followed by a forming
process to create a near-finished product. Entire product chassis
can also be completed this way.
Forming metal not only makes processing easier but also increases
the strength and rigidity of the assembled component.
Sheet Metal Stamping
Stamping is a complex process that combines cutting and forming,
leveraging existing shearing, bending, and drawing techniques. It
can even employ complex die connections to create complex parts in
a short operating time.
Occasionally, this process can be a progressive stamping process,
involving multiple stamping stations that gradually cut or form the
final part. This allows for the efficient production of complex
metal parts.
Punching and Threading
Punching holes in sheet metal can be accomplished using some of the
processes mentioned previously, including laser cutting and
stamping, but there are other methods that will be mentioned here.
Hole punching can be done using a CNC milling machine, a drill
press, or a hand drill. CNC machines are the most precise of these
options, while hand drills are generally the least precise. Each of
these different punching methods has its own advantages and
disadvantages, making them suitable for different applications.
Commonly Used Materials for Sheet Metal Fabrication
This section provides a performance comparison of the various
grades of standard sheet metal fabrication materials offered by
Hongsinn, including aluminum, stainless steel, mild steel, and
copper. More general descriptions of these metals can be found on
this materials page.
| Material + grade | Elongation at break | Machinability | Weldability | Corrosion res | Tensile strength | Cost |
|---|
| Aluminum 5052* | 7 - 27 % | Fair | Good | Excellent | 195 – 290 MPa | $ |
| Aluminum 5754* | 10 - 15 % | Good | Excellent | Excellent | 160 - 200 MPa | $ |
| Stainless Steel 304 | 45 - 60 % | Excellent | Excellent | Good | 480 - 620 MPa | $$$ |
| Stainless Steel 316L | 30 - 50 % | Good | Excellent | Excellent | 480 - 620 MPa | $$$$ |
| Mild Steel 1018 | 17 - 27 % | Good | Excellent | Poor | 190 - 440 MPa | $$ |
| Copper 110 | 15 - 50 % | Poor | Moderate to Poor | Good | 220 - 230 MPa | $$ |
Aluminum series 5xxx is more suitable for sheet metal processing
than aluminum series 6xxx and is often used for CNC machined parts.
This is because aluminum series 5xxx is more ductile and less
likely to tear when bent.
