Guide to Rapid Sheet Metal Services

Sheet metal fabrication is a subtractive manufacturing technique that uses thin metal sheets to create parts. Sheet metal parts are popular because they are versatile and durable. With advances in technology, it is possible to complete sheet metal fabrication projects faster than ever before. In fact, sheet metal is often used for rapid prototyping because of its versatility and efficiency.

What is Rapid Sheet Metal Fabrication

Sheet metal fabrication refers to a collection of operations that use sheet metal to construct parts or finished products. Sheet metal fabrication is extremely versatile and can be used with many techniques and kinds of sheet metal. Rapid sheet metal services enable a quick turnaround on sheet metal projects and are often used to create rapid sheet metal prototypes.

What is Rapid Prototyping

The rapid manufacture of a physical item, model or assembly utilizing 3D computer aided design (CAD) is known as rapid prototyping.

Rapid prototyping has a variety of advantages, including the ability to get a more full view of how a product will look or perform early in the design and production cycle, allowing adjustments or upgrades to be incorporated sooner.

Rapid Sheet Metal Services

Sheet metal is a versatile material that can be fabricated using many techniques, including…

  • Laser Cutting and Punching

    Laser cutters work by concentrating light energy into a laser beam and augmenting it with gas to cut sheet metal. Unlike punches, the sheet remains fixed as the laser head moves in the X, Y and Z axes. Lasers can also be used to etch part numbers and labelling. Laser cutters are more accurate and produce a smoother edge.

    Punching is a machining method for scrap metal removal from a sheet of raw metal. A punch press is used to squeeze a tool through a sheet of raw metal. Punching is often less expensive and faster than laser cutting.

  • Material Graining

    Graining gives sheet metal pieces a consistent surface finish by grinding the metal with a belt grinder.

  • Drilling, Countersinking and Tapping

    Drilling creates higher-quality holes that can be used in thicker materials. Thread-tapping and countersinking are frequently done after that. Thread tapping creates threads inside the drilled hole, allowing for the eventual creation of a bolted link. Countersinking a drilled hole removes the sharp edge and creates a bevel as well as a recess (deep bevel) for a blind bolt head.

  • Forming and Bending

    Cold working activities such as metal bending and shaping allow the sheet metal to be shaped to configurations that allow for creation of the optimal parts.

  • Hardware Insertion

    Sheet metal pieces with hardware insertions provide higher depth for load bearing threads. Hardware insertion uses existing holes generated by high-precision tools such as a laser cutter or a waterjet cutter, which improves fastener placement accuracy.

  • Mechanical Assembly

    Describes the process of assembling sheet metal project components on an assembly line, as well as the end result.

  • TIG, MIG, Spot Welding and Weld Grinding

    Welding is a fabrication method that involves fusing two or more pieces of sheet metal together using heat, pressure, or both to join them as the pieces cool. MIG welding is the fastest option, but the results do not appear as smooth as TIG welding.
    Spot welding is a method of joining two or more pieces of sheet metal by applying pressure and heat to the weld region using an electric current. Weld grinding is a crucial step in many sheet metal production processes that entails removing excess weld metal in a clean and effective manner.

  • Welded Assemblies and Frames

    Sheet metal can be used to create complete welded assemblies and frames for large rapid sheet metal fabrication projects.

The best techniques to use will depend on the specific details of your rapid sheet metal project. Rapid sheet metal prototyping often requires the use of more than one technique.

Common Rapid Sheet Metal Finishing Services

Sheet metal can be finished with different techniques and materials depending on the aesthetic and functional needs of your project.

  • Powder Coating

    Powder coating is a dry coating procedure that is mostly used as a metal finish. Not all materials can withstand powder coating, but most sheet metals can. An electrostatic method is used to apply the powder coating as a dry powder, which is subsequently cured using heat. Powder coating is possible on aluminum, bronze, copper, brass, titanium and steel (including stainless, galvanized, anodized and e-coat).

  • Painting

    Painting is a good option for materials that can’t withstand heat and projects that don’t need to be as durable. There is also a wider color selection available with paint. It may also be less expensive and result in a thinner coating.

  • Chemical Agent Resistant Coating

    Chemical Agent Resistant Coating is a type of paint used to defend military vehicles from chemical and biological weapons.

  • Silk Screening

    Silk-screening (also known as serigraphy) involves applying paint to a specially prepared portion of metal using fine polyester mesh and a squeegee or blade.

  • Laser Engraving

    A laser is used to engrave the sheet metal with a design or identifying mark for manufacturing.

  • Chem Film

    Alodine, often known as chem film, is a chemical conversion coating intended to protect aluminum sheet metal from corrosion.

  • Anodizing

    Anodizing is an electrochemical technique that involves immersing aluminum in a liquid bath and passing an electric current through it. This causes a chemical reaction, thickening the oxide layer on the aluminum’s surface.

  • Black Oxide

    Black Oxide, often known as blackening, is the process of chemically changing the top layer of a sheet metal made of ferrous substance, turning it black and adding durability.

  • Bead Blasting

    Bead blasting is the process of impacting a round spherical material against a part’s surface to provide a more consistent finish caused by the sphere hitting the surface.

  • Tumbling

    Tumble finishing is a method of smoothing and polishing a rough surface on small parts.
