Sheet metal fabrication refers to the processes used to convert flat sheets of metal into three-dimensional objects. This transformation involves a series of techniques, including cutting, bending, and assembling, tailored to produce specific shapes and sizes needed for various applications. Common metals used in this process include aluminum, stainless steel, copper, and carbon steel.
Several key techniques define the sheet metal fabrication process:
1). Laser Cutting: Utilizes a high-powered laser to achieve precision cuts, ideal for complex designs.
2). Water Jet Cutting: Uses high-pressure water mixed with abrasive substances to cut through materials without heat-affected zones.
3).Shearing: A straightforward method that involves slicing the metal along a straight line using blades.
The choice of material is critical in sheet metal fabrication. Common materials include:

Read on to find detailed responses to your metal stamping and fabrication questions. If you don’t see the answer you need, feel free to contact us. We’re happy to help!
Metal stamping can refer to any of a number of metal forming operations—in addition to stamping, bending, pressing, folding, and stretching actions may be used to produce the final part. All metal stamping processes utilize punch presses with custom-made tooling and dies to produce a shape, pattern, or other characteristic a part requires. In general, the stamping process can provide tighter tolerances than metal fabrication. It is a fast and cost-effective way to produce metal parts in large quantities.
Metal fabrication entails the manufacturing of three-dimensional metal parts via cutting, bending, and/or other assembly processes. Fabrication generally requires more specialized equipment, such as CNC laser cutters, CNC press brakes, CNC turret presses, and welding. Metal fabrication is often the more economical way to produce parts in lower quantities, as the tooling associated with stamping can be costly. Fabrication also provides greater design flexibility than stamping, as there is no tooling to change should your part design require alteration.
Tempco offers engineering and prototyping services to help you turn your stamped metal part designs into reality. Our expert engineers can help you optimize your part for the best fit, form, and function, and to make the stamping process faster, easier, and less expensive. Our prototype manufacturing service allows our customers to test-run their parts to ensure that their designs deliver the performance they require. Benefits of prototyping include:
Tempco works with a variety of material in our metal manufacturing processes. Every metal behaves differently in the stamping process, but our experience and expertise enables us to produce all types of metal parts with the same high levels of quality and precision. We can manufacture your metal parts from:
For custom metal stampings, two of the biggest factors that affect price are material type and the tolerances of the part design.
More common or readily available materials are less costly than specialty materials or alloys. To reduce metal cost, consider using an alternative material that provides performance similar to your original material choice. Similarly, materials in “standard” thicknesses cost less than “non-standard” thicknesses. If your parts can be produced from standard thickness materials without significantly altering their fit, form, or function, it is worthwhile to consider this cost-saving option, as well.
Tight-tolerance designs (those requiring tolerances of ± 0.005” or less) generally require more machining operations to hold those tolerances. Tight tolerance parts also often require secondary services , which increases costs, as well. It may be possible to revise your design to reduce certain tolerance requirements or to reduce the need for secondary processing.
The choice between stamping or machining usually comes down to the manufacturability of the part, as well as the quantities required. See “What is the difference between metal stamping and metal fabrication?” (above) for more detailed information on each process.
The metal stamping process generates less material scrap than machining. This helps keep costs down and can be especially important when working with more expensive specialty materials like titanium or tungsten. There are multiple types of stamping operations, including punching, blanking, embossing, flanging, and coining. In general, metal stampings are far lower in price-per-piece than machined parts, even when secondary services are required to meet tolerances.
Metal fabrication is generally used to produce more complex parts that require multiple operations to complete. Whereas metal stamping is often used to create a simple flat (or 2D) part, fabrication is often a better choice for producing 3D parts.
A “progressive die” is a series of punch press tools that have been specially designed to perform all the punching, cutting, coining, and bending required to produce a metal part through a multi-step process. In progressive die stamping, a strip of metal is fed through all stations of the progressive stamping die; each station performs one or more operations until the part is completed.
If you require complex, three-dimensional parts in quantities greater than 15,000 per year, progressive die stamping is an excellent manufacturing solution. Progressive die stamping is fast and efficient, and, for larger quantities, is one of the most cost-effective manufacturing processes available.
At Tempco, we manufacture all of our own tooling, dies, and fixtures. Our state-of-the-art tool and die shop enables us create high precision tooling and dies for even the most complex metal stamping and fabricating projects. We also store, maintain, and replace non-permanent dies at no cost to our customers.
In general, the lead time for tool and die manufacturing depends on the complexity of the punch design, the number of total operations needed to produce your part (for progressive stamping), and the quantity of parts required. Single stage tooling usually takes roughly 4 to 6 weeks to produce; progressive tooling usually takes 8 to 10 weeks.
With U.S.-based manufacturing, you can count on better quality parts and components, reliable two-way communication, and on-time delivery. American manufacturers are the best in the world, producing the highest quality, tightest tolerance parts. Domestic manufacturing allows for faster turnaround times and more dependable deliveries. For top quality parts delivered on your schedule, there’s no substitute for American manufacturing.
