Sheet metal is the general term covering thin sheets of metal stock within the range of 0.006 and 0.25 inches of thickness. Sheet Metal Fabrication is a modern manufacturing technique that involves the use of metal sheets to form parts. Sheet metal processing starts with a 3D Computer-aided-design (CAD) file that is converted to a set of languages/instructions readable by a machine (code). These codes direct the machine tools on how to cut the metal sheets for forming the final part.
With an average lead-time of 24 hours per project and over 25,000 parts fabricated each month, First Part sheet metal fabrication service is your one-stop-shop for making metal prototypes, custom assemblies, low and high-volume sheet metal parts in a matter of hours.
Unlike conventional sheet metal workshops, our digital capabilities, cross-manufacturing technology, instant quoting system, and robust material selection means you can cut down on production time and become market-ready in a matter of days!
· Low-volume manufacturing
Sheet metal fabrication id ideal for making small volumes of a part without incurring expensive tooling costs. Because of the affordability of the process compared to CNC machining and 3D printing, processing small units of part with sheet metal fabrication is usually cost-effective.
For sheet metal fabrication, brakes, dies, punches and presses represent the majority of the forming tools. These tools can compress the metal sheets into angular bends, complex geometries, and detailed features. Sheet metals can be processed by bending, curling, punching, shearing, hydroforming, spinning, laser cutting, and ironing. Once certain features/fragments of the part are made, they are neatly joined together by welding and improved for visual and cosmetic aesthetics with an array of finishing services.
Sheet metal parts are mostly manufactured for use as chassis, enclosures, and other high-durability purposes. Due to the material and setup costs, sheet metal fabrication is utilized for high volume production and low-volume prototyping for cost-effectiveness. At First Part, our sheet metal fabrication services are well-tailored for our client's needs, representing the perfect opportunity for quick prototyping, robust testing, and faster market entry.
Cutting operations in sheet metal processing may be done with/without shear.
The shear cutting processes are blanking, cutting, and shearing. Non-shear processes are more precise and tailored for high-accuracy industrial end products.
Water jet cutting:
A high-velocity process that directs abrasive-concentrated streams of water at the sheet to cut into the material.
Can be conventional or CNC-based. This process involves the use of a tool (drill bits or lathe blades) to systemically remove pieces of material from a part. CNC milling, spinning, and turning are some of the most popular processes.
Forming is the general umbrella for processes like stamping, stretching, roll-forming, and bending. Unlike cutting where the material is removed from sheet metal, forming simply uses fabrication tools to reshape the part to the desired geometry.
A forming technique involves the use of two dies to press the metal into the desired shape.
Contours a sheet metal, and can be done by hand or brake press, while roll-forming uses a pair of rolls to process an entire length of sheet metal into a coil.
Joining is usually but not necessarily the final process in sheet metal fabrication. It involves processes like riveting, adhesives, brazing, and most popularly, welding.
Depending on the type of part to be manufactured, the complexity of the design and the desired finish, metal sheets may be formed in 3 simple steps namely cutting, forming, and joining. (assembly)
Non-shear processes include laser beam cutting, water jet cutting, plasma cutting, and machining. They are more suitable for industrial use in automotive and aerospace, robotics, and sometimes engineering.

First Part Sheet Metal parts can be used for:
· High-functional end-part production
Sheet metals are very machinable, making them processable into just about any shape, angle, and size. This makes it an excellent choice for making high-precision and functional end parts with tight tolerances
· Rapid Prototyping
Sheet metal techniques can be used with CNC machining to create and test high-fidelity prototypes made in production-grade materials.
· Enclosures, Brackets, and Chassis
Thin metal parts are easily made into functional enclosures, brackets, and chassis through sheet metal processing. Sheet metal fabrication is a feasible method of making device panels, chassis, brackets, boxes, and enclosures of all styles to fit electronics and consoles.
All parts are made to critical dimensions, allowing for proper placement of internal components, hardware, and fasteners.
Aluminum has an excellent strength/weight ratio. It can also withstand lower temperatures, making it suitable for use in aerospace and cooling technologies.
Copper has great electrical conductivity. It is ductile, malleable, and well suited for corrosion-resistant components.
Excellent for applications that favor strength and durability.
Magnesium sheet metals have low density. They are for applications where stiffness is desired.
Brass is lightweight and corrosion-resistant. It is well suited for making fittings and components as well as parts that need acoustic properties.
Bronze boasts of higher strength than copper. It has a low melting point, making it suitable for use in turbines and cookware.
The above materials are the most common stock material options. If your desired material is not listed above, please contact our team here. You may learn more about our other options and custom material applications by clicking here to go to our materials page.
Molded parts can be finished in many ways that may cover purely aesthetic finishes or offer some form of protection to the part. Finishes should beautify and enhance the sophistication and functionality of any part. At First Part, our Injection-molded parts may be finished in any of the following options:
· As manufactured
Sheet metal fabricated parts are left as manufactured. There will be visible tooling marks on the part.
· Bead blasting
A surface smoothing operation that involves the direction of fine glass beads at a part’s surface under high pressure. Bead blasting creates a smooth, uniform surface finish on the part.
An electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of the part. This can be used for decorative, anti-corrosion or surface hardness treatments. Anodizing is most common with aluminium parts.
· Powder coating
Electrically conductive sheet metal parts may be coated with colored powder paint after fabrication to deliver a dry, melted and hardened finish to a part. Very suitable for workpieces that need textures that may not be achievable using wet painting.
This involves the deposition of a thin chromium layer onto a metal part through an electroplating process. The chromium layer may serve decorative functions, make the part anti-corrosion or improve the surface hardness.
An array of custom finishes are also available for your part depending on material and purpose of the end-use part.
