Guide to Prototek Sheet Metal Fab
Sheet metal fab, a common shortened term for “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. As a sheet metal fab shop, we employ multiple specialists and have a variety of machines for different purposes. During sheet metal fabrication, we often use multiple techniques simultaneously to create a finalized part.
What is Sheet Metal Fab?
Sheet metal fab is a group of processes that involve the use of sheet metal to create parts or completed products. Sheet metal manufacturing is incredibly adaptable, and it can be employed with a variety of processes and sheet metal types.
Services Offered at Our Sheet Metal Fab Shop
Because of sheet metal’s versatility, we use a variety of techniques to reach a final product. Some of those sheet metal fab services include the following:
Laser Cutting and Punching
This involves cutting sheet metal by focusing light energy into a laser beam and supplementing it with gas. The sheet remains fixed when the laser head travels in the X, Y and Z axes, unlike punches. Part numbers and labeling can also be etched with lasers. Laser cutters are more precise and generate a smoother edge than traditional cutters.
Punching is a machining technique for removing scrap metal from a raw metal sheet. To squeeze a tool through a sheet of raw metal, a punch press is utilized. Punching is frequently less expensive and more efficient than laser cutting.
Graining is the process of grinding sheet metal components with a belt grinder to achieve a consistent surface polish.
Drilling, Countersinking and Tapping
Drilling produces holes of superior quality that can be used in thicker materials. Following that, thread-tapping and countersinking are usually performed. Thread tapping establishes a thread inside the drilled hole, which allows a bolted link to be created afterwards. A countersink removes the sharp edge of a drilled hole and generates a bevel as well as a recess (deep bevel) for a blind bolt head.
Forming and Bending
Forming and bending are cold-working techniques to change the shape of sheet metal. The metal must be stretched beyond its elastic limit without cracking or splitting.
Higher depth for load bearing threads is provided by sheet metal components with hardware insertions. Fastener placement accuracy is improved by using existing holes created by high-precision instruments such as a laser cutter or a waterjet cutter.
Mechanical assembly involves assembling sheet metal fab components together to complete the final part or product.
TIG, MIG, Spot Welding and Weld Grinding
Welding is a fabrication technique which involves joining two or more sheets of metal together by heat, pressure, or both while they cool. The fastest alternative is MIG welding, although the results are not as smooth as TIG welding.
Spot welding is a method of uniting two or more pieces of sheet metal using an electric current to impart pressure and heat to the weld zone.
Weld grinding is an important stage in many sheet metal fabrication processes because it involves removing extra weld metal in a safe and efficient manner.
Welded Assemblies and Frames Offered
For big quick sheet metal fabrication projects, sheet metal can be used to build full welded assemblies and frames.
The best techniques to use will depend on the specific details of your sheet metal fab project. As a sheet metal fab shop, we can help you determine the best strategy for your particular needs.
Finishes Available for Our Sheet Metal Fab
Sheet metal fab can be finished with different materials and methods depending on the aesthetic and functional needs of your project. Those include:
Powder coating is a dry coating process that is mostly used to finish metal. Powder coating is not suitable for all sheet metal fab materials; however, it is suitable for most sheet metals. The powder coating is applied as a dry powder using an electrostatic process and then cured with heat.
Painting is a good alternative for sheet metal fab projects that involve heat-sensitive materials and tasks that don’t require a lot of durability. With paint, you can choose from a greater range of colors.
Chemical Agent Resistant Coating
Chemical Agent Resistant Coating is a form of paint that is used to protect military vehicles against chemical and biological weapons.
Silk-screening involves using thin polyester mesh and a squeegee or blade to apply paint on a properly prepared area of metal.
In sheet metal fab, a laser is sometimes used to engrave a design or an identifying mark on the project after completion.
Alodine, often known as chem film, is a corrosion-resistant chemical conversion coating for aluminum sheet metal.
Anodizing is an electrochemical process in which aluminum is immersed in a liquid bath and an electric current is passed through it. The oxide layer on the aluminum’s surface thickens as a result of the chemical process.
Black Oxide 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 is the process of striking a round spherical substance against a sheet metal project’s surface to provide a more consistent finish.
Tumble finishing is a method of smoothing and polishing a rough surface on small parts made of sheet metal.
