It’s no doubt that sheet metal is the essential material in applications for numerous industries and fields. Before such a sheet metal being processed to become the finished products with a variety of shapes and forms, it’s generally a thin sheet or panel in a flat form as the original material for convenient transportation and storage. So for the industries using such a type of material, sheet metal forming and other fabrication processes are the common and important parts, and how to do the sheet metal forming and shaping is determined by the application on request.
Sheet metal comes with tensility, ductility, and formability, these features are suitable and beneficial for fabrication processes, so it’s extensively used. Sheet metal is malleable for flexibly manipulation, and it’s durable enough to preserve well structural integrity. Sheet metal shaping is achieved by multiple methods and different types of facilities. In this article, we will discuss some sheet metal forming processes and some other relative information about it.
6 Types Of Sheet Metal Forming Processes
For a large amount of purposes of sheet metal, there are a wide range of processes for forming stainless steel sheet and aluminium sheet sheet metal that can be applied by using machines and mechanical tools, which are driven by electricity, manual power, pneumatics or hydraulics. The forming options mainly depends on the the desired qualities and applications. And what processing methods to be applied are also determined by the cost and order quantity, and other determining factors. Here are several common process methods of sheet metal forming for you to know which is the proper one for your requirements.
What Is Sheet Metal Forming
Sheet metal forming includes a series of metal processes in which force is used to pieces of flat metal sheet, such as bending, folding, curling, stamping, and other forming methods, the flat sheet can deform into a variety of shapes and forms. However, sheet metal forming changes the shape and adds some properties and values for specified applications and purposes, this process can be applied to make a wide range of different metal products such as decorative metal panels, appliance enclosures, furniture parts, and components and parts for many industries.
Sheet metal forming is a high-speed process, which provides efficiency that is higher than other material types, so it’s very suitable for large batch production. Generally speaking, components or products made of fabricated sheet metal come with precision and dimensional stability as the thickness of metal sheet essentially has no change, or the slight change is acceptable in most applications or cases. So fabricated sheet metal products commonly have precise tolerance, clear surface, and durability.
Which Industries Use Sheet Metal Shaping
In the forming process and application, there are a difference between sheet metal and plate metal. The thickness of sheet metal is between 0.5mm and 6mm, and plate metal are the thicker metal piece that is more than 6mm. Sheet metal is usually applied for decorative metal products, and components and parts for furniture, appliances, machines, cars, trans, cans, etc. And plate metal is commonly used for large or oversize parts and components such as turbines, boilers, ships, aircraft, bridge, and construction.
Benefits of Using Sheet Metal Forming
There are some benefits of sheet metal shaping when you are using that to make your own products. It can help you achieve to various purposes and some practical utilities, as metal is extremely flexible for manufacturing, it can allow you to get various options of different shapes and styles. No matter which methods of process is used, all the things they do are to change the shapes and forms get improvements of properties and value, and there no loss or waste on process, as metal is a recyclable material, so it’s widely used in most industries.
What To Consider When Forming Sheet Metal
When sheet metal is formed and shaped, the force is used evenly and selectively. Rounding bending machines, press brakes and embossing machines can achieve different types of shapes, The deformation degree is determined by the forming force degree. In the press brake, the sheet metal is pressed with a certain force. A force with an even strength is used in the opposite direction. The interaction force between two parts need to be strong enough, so that the metal sheet is permanently formed. For this, the force used have to be stronger than the degree of resilience force. The degree of force has to be applied to the extent that the metal sheet can withstand.
The metal type and its tensile strength also need to be taken into consideration. The forming force need to be controlled under the tensile strength to prevent breakage and crack to the metallic material. To analyze the forming force required, you need to have an idea about the edging length, which increases proportionally to the applied length. Additionally, the bending angle, the rolling direction, the sheet thickness and some factors required need to be considered. The bending radius required depends on the thickness of metal sheet. If the tool is lower than the minimum bending radius, the sheet can crack to be damaged.
