What Is Sheet Metal Fabrication?

Sheet metal fabrication is a subtractive manufacturing process that forms parts from thin metal sheets. Engineers often choose sheet metal parts for their high precision and durability, especially for end-use applications like chassis, enclosures, and brackets.

Xometry’s sheet metal fabrication services provide a fast and cost-effective solution for any parts that need to be made from 3D CAD files or engineering drawings. Xometry offers a range of sheet metal materials, including aluminum, copper, steel, and stainless steel, as well as assembly services like installing PEM inserts, welding, and finishing services. With a network of domestic and overseas fabricators, Xometry can supply any quantity of parts from low-volume, high-mix prototypes to high-volume production runs. Xometry offers competitive sheet metal prices for low volume prototypes and cost savings for high volume production runs.

    How Xometry Sheet Metal Fabrication Works

    Xometry's metal fabrication services utilize the top sheet metal fabricators in the US and globally. Sheet metal fabricators first convert CAD and drawing data into machine code. A laser cutting, waterjet, or plasma cutting machine will then precisely remove sheet metal material. The raw material is formed into angular bends and features using brakes, punches, and dies. If any assembly or post-processing is required, our sheet metal manufacturers will weld, add inserts, or finish the part.

    The efficiency and high precision of metal fabrication, coupled with Xometry’s variety of materials, range of sheet metal fabricators, and post-processing options means you can get parts for any application. Sheet metal applications include aerospace, defense, automotive, energy, industrial, medical, dental, and consumer products.

      Minimal post-processing or treatment on parts is done.

      Bead Blast

      The part surface is left with a smooth, matte appearance.

      Anodize (Type II Or Type III)

      Type II (MIL-A-8625, Type II) creates a corrosion-resistant finish. Sheet metal parts can be anodized in different colors—clear, black, red, and gold are most common—and are usually associated with aluminum. Type III (MIL-A-8625, Type III, Class 1/2 "hardcoat") is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.

      Chem Film (Chromate Conversion Coating)

      This sheet metal finish provides corrosion resistance and good conductivity properties. Chem film can be used as a base for paint and can leave surfaces yellow or gold. Adds very little thickness, about 0.00001”-0.00004.” Chem film will conform to MIL-DTL-5541, TYPE I/II.

      Powder Coat

      This is a process where powdered paint is sprayed onto a part that is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.

      Electroless Nickel Plating

      Provides uniform nickel coating which offers protection from corrosion, oxidation, and wear on irregular surfaces. The finished part will be brighter. Thickness starts at .0001” and this finish conforms to MIL-C-26074.

      Gold Plating

      Gold Plating provides good corrosion and tarnish resistance with excellent solderability. Default application specification is MIL-G-45204 & ASTM B488, CLASS 00, 0, OR 1 (Thickness 0.00002" - 0.00005").

      Silver Plating

      Silver offers high solderability and electrical conductivity but is susceptible to tarnish on sheet metal parts. Conforms to AMS QQ-S-365D. Thickness is about 0.00002”- 0.0003.”

      Applications and Advantages of Sheet Metal Fabrication

      Laser cutting metal sheet

      Rapid Tooling

      Sheet metal can be quickly cut into 2D profile shapes and formed out of a variety of high-strength materials, making it perfect for rapid tooling.

      Sheet Metal

      Rapid Prototyping

      With lead times starting at 3 days, no minimum order volumes, and low-per-unit costs, rapid sheet metal is a great option for prototyping.
