Introduction to Precision Sheet metal fabrication

Precision sheet metal fabrication?

Taking any metal that can be stretched out and manipulated into a metal sheet and finally assembling into a product is known as precision sheet metal fabrication.

Still confused?

We can help you clearly understand by showing the processes involved and the tools used for the same.

Precision Sheet metal fabrication comprises of 5 major processes as listed below:

Step 1:

Design and Development

This is the initial phase where the client will work with the design team to outline the precision sheet metal project in detail. At this stage, the specification including measurements and quality of the sheet metal are discussed. Once the specifications are confirmed the designers develop the design and get the approval from the client.

The development is done in a 3D environment where the clients can see their designs getting a life. This stage of the project is exciting as the client can view the designs as a digitized, provisional perception of the final sheet metal product.

Step 2:


This is a very crucial stage in development because at this stage the client’s thoughts become a tangible reality for the first time. A prototype is created using stainless steel, sheet metal or non-ferrous metal, using the 3d designs in the developmental stage. Prototyping plays a major role in precision sheet metal fabrication.

Step 3:


The lengthiest and most important phase starts here. This stage can be broken into different phases, wherein every phase require different tools and different skilled labor.  The main phases are Shearing, laser cutting, NC Punch press, cleanup, forming, hardware, welding, inspection, ship to an outside process. All these processes finally give a precision sheet metal product.

Step 4:


At this stage, the final sheet metal products are inspected by a quality inspector to make sure they meet the standard precision sheet metal fabrication quality requirements and are defect free.

Step 5:


The final stage of development is shipping. Tools like ERP, MRP and dynamic inventory modeling are mostly used to do this process. At this stage, various packing techniques are used to ensure the safety of the sheet metal parts during the transit.

  1. That’s interesting that when you do a sheet metal project that the customer can see it as a 3D environment before deciding to proceed further. My son mentioned to me about sheet metal cutting projects and how that is what he wants to work with after he graduates college. I wonder what kind of projects you can make with them and how big and small they can be.

  2. I love what you said about prototyping and how it’s a crucial stage of sheet metal fabrication. I think that sheet metal is versatile, especially when it comes to architectural purposes. If I were to need such a product, I would contact a reputable supplier that is known for their fair rates.

  3. I liked how you mentioned quality control and how you have an inspector come in to check everything. I am always curious how this works out with controlling quality of different products. It’s good to know that there is a whole step where this is taken care of.

  4. I love that you said that the manufacturing stage is the lengthiest and most important phase in metal fabrication. Truth be told, sheet metal fabrication is endless. There are a lot of factors needed in the process such as weldability, machinability, and ductility. Thanks for mentioning that clients can actually see in the 3D environment the development if they would still want to push through with the project or not.
