Sheet metal bending is a manufacturing process in which you will use various bending techniques to bend sheet metal materials to achieve certain geometries or shapes. With bending sheet metal, you will need to use sheet metal materials with certain malleable qualities, as you need them to bend without breaking.
In this guide, you will learn all about sheet metal bending, which includes its applications, key benefits, and how you can use it in your manufacturing activities.
Understanding about Sheet Metal Bending in Manufacturing and How It Works
Just like with any other manufacturing processes, bending sheet metal requires you to use a certain equipment to bend the metal sheets into the shapes you would like to get. Then, you will also need to use the CNC or laser cutting method to complement the primary bending process. To understand it further, let’s delve deeper into how sheet metal bending works.
Here’s the way sheet metal bending works in manufacturing:
- Creating the design for your sheet metal components. First, you will need to prepare the design you will use for your sheet metal components, which includes the shapes, geometries, holes, and many other aspects of the hardware parts. You will follow this design blueprint later.
- Preparing the sheet metal materials. Depending on the parts and components you would like to produce, you will need to prepare the sheet metal materials suitable for your final products. There are various available sheet metal materials, such as alloy steel, aluminum, carbon steel, and so on. Each material will have its own characteristics, such as malleability and durability.
- Preparing the bending equipment. Next, you will need to prepare the bending equipment you will use for the sheet metal. This equipment will make it easy for you to bend the sheet metals according to your specific configurations. The bending equipment will allow you to perform the bending sheet metal process at certain angles or at any other configurations, such as bend radius, bend allowance, over bending, and so on.
- Determining the bending radius and bend allowance. You will also need to determine the bend radius and bend length of the sheet metal to get the shape you need. Depending on the sheet material type, you can create some room for the sheet metals to bend at a certain angle or at a certain radius to allow additional manufacturing steps later.
- Using CNC machining or laser cutting for additional processes. CNC machining or laser cutting methods will be useful to cut the sheet metals or to add holes and other intricate shapes for the sheet metals.
Key Benefits of Sheet Metal Bending in Manufacturing
In manufacturing, sheet metal bending is a process that can give you various key benefits, such as little to no tooling requirements, lightweight materials, superior accuracy, and cost-effectiveness. You can use this manufacturing method to create prototypes, parts, and components with complex geometries.
Here are some key benefits of sheet metal bending in manufacturing:
- No tooling required. Unlike plastic molding and other manufacturing processes, you don’t need to create any tooling for the bending sheet metal process. Yes, you can use some tooling in some cases, but sheet metal bending is a manufacturing process that requires little to no tooling. You just bend the sheet metal materials to create various geometric shapes that you need to use to build your hardware parts and components.
- Lightweight. Sheet metals are lightweight materials that you can use in various applications. However, even though it is lightweight, sheet metals still offer you the sturdiness and durability to create the best quality parts and components for any industry.
- Best accuracy and measurement. It is very easy for you to use sheet metal materials to create accurate parts and components, especially if you use the CNC cutting methods that you can program for the best accuracy. In some cases, it’s easier for you to work with sheet metals compared to any other manufacturing methods in terms of creating precision and accuracy in the part’s measurements.
- Cost and production efficiency. Sheet metal materials are much more cost-effective than the materials you are using for other methods. The easier production process can also lead to easier production for the parts and components you produce. Bending the sheet metals also doesn't require you to use expensive equipment to do so, and the process is also simple and easy to perform.
- Quick production speed with minimal post processing. Sheet metal bending is a programmable manufacturing process that you can set and configure based on your requirements. So, you will have a fast production speed when you use this process. This manufacturing method also doesn’t require too much post processing, as the produced part will be ready for you to use after the bending metal sheet process is complete. You don’t need to polish or apply additional heat treatments to the materials just to make them ready for use.
Sheet Metal Bending Applications in Various Industries
Not all parts and components can be produced with plastic mold injection or DIY injection molding. There are some parts and components in various industries that can be produced in better ways by using sheet metal bending. By using the bending sheet metal equipment, you can apply force to the sheet metal materials to bend them and create shapes that you want to get.
Sheet metal bending has been used in various manufacturing industries, such as automotive, aerospace, and construction industries. In the automotive industry, the applications of sheet metal bending include the production of exhaust systems, hoods, fenders, and many others. In the aerospace industry, you can find bending sheet metal to be a preferable manufacturing method to produce airplane wings, fuselage, and various parts of the airplane body. Then, in the construction industry, sheet metal bending is useful to produce building roofs and metal frames.
How to Use Sheet Metal Bending in Your Manufacturing Activities
Do you need to use sheet metal bending in your manufacturing activities? Be sure to do it the right way. These are some tips you can follow to get the best result when using sheet metal bending in your manufacturing activities:
- You need to consider the malleability of the sheet metals and match them with the bending requirements to produce your parts or components.
- It’s best to avoid bending sharp corners, because it will often make you stuck and make it difficult for you to follow the manufacturing process further.
- Protecting the sheet metal surface might be a good idea during the bending process, as it can provide you with the best result in your sheet metal bending.
- Bending heavy materials might require you to use additional heat to smooth the process, which is required if you would like to produce durable parts and components.
- To avoid any waves or unintended bends, you can use a brake to make the bending process much cleaner and softer, while avoiding any bad results for your sheet metal materials.
Sheet metal bending is one of the quick manufacturing methods manufacturers can use to create hardware parts, prototypes, and components with little to no tooling. You just need to prepare the sheet metals that meet your requirements and are suitable for your project, and then use the bending equipment to bend them according to your specific configurations.
With the wide range of applications of bending sheet metal, you can use this method to produce quick parts and components for various industries, whether it is automotive, construction, aerospace, or any other industries.
