The role of our sheet metal workshop, the capabilities of our metal laser cutting services, and the complexity of precision sheet metal fabrication combine to provide high-quality, custom solutions for industries such as aerospace, automotive, medical, and electronics.

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.

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.
