Sheet metal fabrication transforms flat metal sheets into a finished product through cutting, forming, and joining. Custom sheet metal fabrication is widely used in various industries, such as automotive, construction, electronics, and aerospace. This technique is essential to many manufacturing processes and can create everything from automobile parts to electronic enclosures. In this blog, we will see the best techniques for custom sheet metal fabrication, how to choose the proper technique for your needs, the typical applications of sheet metal fabrication, and the benefits of using this process.
Techniques for Sheet Metal Fabrication
Several techniques are used in custom sheet metal fabrication, each with benefits and limitations. Here are some of the most commonly used techniques for cutting, forming, and joining sheet metal.
- Laser Cutting – A high-powered laser beam accurately cuts through the metal sheet. This technique suits various materials, including stainless steel, aluminum, and copper.
- Waterjet Cutting – A high-pressure stream of water mixed with abrasive particles cuts through the metal sheet. This technique is best suited for materials that are sensitive to high temperatures.
- Plasma Cutting – A high-temperature plasma torch melts through the metal sheet. This technique is suitable for cutting thicker sheets of metal quickly.
- Bending – The metal sheet is bent to a desired angle using a bending machine. This technique is commonly used to produce sheet metal parts with complex shapes.
- Rolling – The metal sheet is rolled into a cylinder shape using a rolling machine. This technique produces pipes, tubes, and other cylindrical structures.
- Stamping – The metal sheet is pressed into a desired shape using a stamping machine. This technique is commonly used to produce high-accuracy and precision metal parts.
- Welding – Two or more metal sheets are joined together by melting, allowing them to cool and solidify. This technique is suitable for joining sheets of the same material.
- Riveting – A metal fastener joins two or more sheets of metal together. This technique is suitable for joining sheets of different materials.
- Adhesive bonding – A specialized adhesive joins two or more metal sheets together. This technique is suitable for joining sheets of different materials and provides a solid and durable bond.
Combining these cutting, forming, and joining techniques allows custom sheet metal fabrication to produce various parts and products.
Choosing the Right Technique
When choosing a custom sheet metal fabrication technique, there are several factors to consider, including material type, material thickness, precision requirements, and production volume. Here are some things to remember when selecting the proper technique for your needs.
- Material type – Different sheet metal materials require different cutting and joining techniques. For example, stainless steel may require laser cutting, while aluminum may be best cut with waterjet cutting.
- Material thickness – The thickness of the sheet metal also affects the choice of cutting technique. Laser cutting suits thinner sheets, while plasma cutting is better suited for thicker sheets.
- Precision requirements – Some applications require high levels of accuracy and precision, such as those in the electronics industry. Stamping and bending techniques can produce parts with high accuracy and repeatability.
- Production volume – The production volume of parts can affect the choice of cutting technique. For high-volume production, stamping and bending may be more efficient, while for low-volume production, laser or waterjet cutting may be more cost-effective.
- Considering these factors, you can choose the correct sheet metal fabrication technique for your application, producing high-quality parts and products.
Common Applications of Sheet Metal Fabrication
Sheet metal fabrication is used in various applications across different industries. Here are some common examples of where custom sheet metal fabrication is used:
- Automotive Industry – Sheet metal fabrication is used to manufacture various parts of automobiles, including body panels, exhaust systems, and chassis components.
