What is Sheet Metal Fabrication?

 

Sheet metal fabrication is the umbrella term for many processing methods used to transform flat and thin sheets of metals into high-quality end-use parts. Sheet metals refer to thin sheets of metal stocks that are no more than 0.25 inches thick.
The process begins with a CAD file – a digital copy of the final design intended for the part. Depending on the fabrication process, the sheet metals may be cut with a laser cutting machine that uses pre-programmed instructions to direct the cutting tool paths. Alternatively, the parts are fabricated through one or a combination of laser cutting, milling, forming, bending, punching, cutting, or stamping processes. Sheet metal parts can have simple or complex geometries. The affordability, scalability, and range of material selection make sheet metal fabrication popular across several industries. It is popularly used in making part enclosures, brackets, and chassis.
At Premium Parts, our sheet metal fabrication can be used for quick prototyping, low-volume production, and mass production.

Our Sheet Metal Fabrication Processes


There are several forming processes for making sheet metal parts. The fabrication method usually depends on the size of the part, the complexity of the design, and the finish type. At Premium Parts, we offer the most popular metal fabrication operations covering cutting, forming, and joining processes. Some of our techniques include:

Metal deformation 
      o Bending 
      Contouring of sheet metals into several shapes with hand or brake press 
      o Stamping 
      Use of two dies to press and “stamp” the metal till the desired shape is achieved 
      o Spinning 
      Rotation of sheet metal at high speed by lathing machine to form an axially symmetric part

Metal forming/assembly 
      o Assembly 
      Using rivets or weld to assemble and put sheet metal parts together as one final component 
      o Roll forming 
      Processing of flat sheet metals into a coil with the use of rolls
      o Welding
      Infusion of two or more sheet metal parts with a special flame that melts parts together in the presence of a filler. 
      o Riveting 
      Joining of two metal sheets together by embedding small metal parts through the sheets. 
      o Brazing
      Infusion of two or more sheet metal parts with a special flame that melts the filler to join the pieces.


• Material removal 

     o Laser cutting

     Laser-focused light beam for precision cuts into sheet metals.

     o Punching

     A hole-forming process achieved using a punch and a die to force a hole into a metal sheet sandwiched between. The size and shape of the hole depending on the die.

     o Machining

     Use of CNC machines, tool paths, and cutting tools to make highly accurate and precise cuts until the sheet metal is formed into the desired path. CNC milling and spinning are popular for sheet metal applications.

     o Plasma

     High-speed, heat-compressed plasma directed at sheet metal for cutting operations.

     o Waterjet

     High-velocity concentrated water streams for cutting sheet metals.


  


Advantages of Sheet Metal

 

1. Strength/Weight Ratio
Strength/Weight Ratio

Sheet metal parts made from steel, aluminum, and copper have excellent strength-to-weight ratios. This makes them ideal for applications where both high strength and lightweight are vital.




2. Scalability

Scalability

Sheet metal fabrication can make high-quality parts independent of volume. With sheet metal fabrication, you can expect the same quality on ten parts to be consistent with one thousand pieces. This is excellent for rapid prototyping and low-volume manufacturing. 




3. Affordability 

Affordable pricesSheet metal parts can make large volumes of end-parts at a lower cost-per-unit. It is a more effective solution for producing quality end parts.




4. Durability

DurabilitySheet metal produces highly durable metal parts and is well-suited for both functional prototypes and end-use production.




5. End-use product quality

End-use product quality Sheet metal parts are durable for direct application components and as part of other parts. Most sheet metal parts can be used directly to the end-use product after painting or plating.




6. Custom finishes 

Custom FinishSheet metal parts can be painted, anodized, plated, and finished in several ways to beautify and improve your parts' functionality.




Applications of Sheet Metal Fabrications

Sheet metals can be typically used to make the following parts and components: 

Chassis       

Surgical implants       

Chipsets and boards       

Office equipment       

Brackets       

Chassis       

Enclosures       

Culinary, Cutlery, and Kitchenware      

Body panels 

On-demand production 
Sheet metal parts are suitable for on-demand production and mass manufacturing as needed. This is because sheet metals can be easily fabricated into desired angles, forms, and shapes.

Rapid prototyping
Sheet metals can make high-fidelity prototypes in various production-grade materials starting from one unit.

Low-volume manufacturing
Sheet metal fabrication can make low-volume units of your parts without compromising quality and durability. At Premium Parts, you can receive low-volume units of your parts in as fast as seven days or lesser.
