Creating intricate patterns and curves in sheet metal requires bending and forming. Precision sheet metal bending and forming employ several techniques, including:

  • Press brake forming: A press brake is employed to bend the sheet metal into the desired shape.
  • Roll forming: The sheet metal is moved through a set of rollers to get the desired shape.
  • Stretch forming: The sheet metal is stretched over a die to produce the desired shape.

Joining is the process of fusing two or more sheets of metal. Precision sheet metal joining involves some processes, including:

  • Welding: The process of joining two or more metal sheets together under pressure and heat.
  • In brazing, a filler metal melts at a higher temperature than the sheet metal joins two or more pieces.
  • With a low-melting-point metal alloy, two or more sheets of metal are connected by soldering.

Enhancing the sheet metal’s durability and aesthetic appeal is the process of finishing. Precision sheet metal finishing uses a variety of processes, such as:

  • Polishing: The sheet metal is polished to produce a shiny, reflective surface.
  • Painting: A coat of paint is applied to prevent corrosion and improve the sheet metal’s look.
  • Powder coating: To generate a long-lasting, protective coating, a dry powder is put to the sheet metal and cured in an oven.
  • Anodizing: A procedure that coats sheet metal with a protective oxide layer to increase its corrosion resistance.
