What is Sheet metal fabrication?

Sheet metal fabrication is the process of forming parts from sheet metal. The 3D CAD files are converted into machine code that controls the machine to precisely cut and form the sheets into the final part. Typical molding tools are brakes, punches, and dies, which can form angular bends and features. Installing inserts, such as the PEM  inserts, is standard practice for welding and finishing services. Sheet metal parts are known for their durability, which makes them ideal for end-use. Because of the large initial setup and material costs, parts for  low volume prototypes and high volume production are most cost-effective.

Our custom sheet metal service provides you with a cost-effective on-demand solution for your manufacturing needs. Processing services range from low volume prototyping to mass production, which can save a lot of cost.

How Does Sheet Metal Fabrication Work?

There are 3 common stages in the sheet metal fabrication process, all of which can be completed with various types of fabrication tools.

  • Material Removal: During this stage, the raw workpiece is cut to the desired shape. There are many types of tools and machining processes which can remove metal from the workpiece.
  • Material Deformation (forming): The raw metal piece is bent or formed into a 3D shape without removing any material. There are many types of processes which can shape the workpiece.
  • Assembling: The completed product may be assembled from several processed workpieces.

Many facilities offer finishing services as well. Finishing processes are usually necessary before a sheet metal-derived product is ready for market.
