4 common metal stamping process
Depending on the shape of the part or product, metal stamping involves a variety of different processes, each different. These processes are used to achieve complex and detailed designs of parts and products in industries including aerospace, consumer products, automotive, aviation, electronics, food and beverage, and more. It is generally not possible to manufacture a part with one metal stamping method, as each process involves making a specific design.
Many stamping technologies involve processes such as extrusion, stretching, and bead pressing. Each technique involves a mix of various processes to achieve the desired part. All of these methods are performed at room temperature and usually involve minimal or zero heat. Metal stamping is a typical cold forming manufacturing process that involves the use of several tools and equipment, such as stamping machines (punch presses), dies, etc., to create complex shapes and appearances.
Punching is a common metal stamping process. A sheet of metal is fixed in one place, or more precisely, a work surface. Using different tools and machines, a hole is made in the sheet metal and a series of different hollow areas are created in the sheet. Punching is a bit different because after punching a hole in a metal sheet, the part with the hole is removed and is no longer used. To ensure that the sheet metal is not deformed, punching must be a continuous process. The area around the punching hole must be precisely designed. The machines used in this metal stamping process are made of high carbon steel and must be thoroughly maintained so that there are no areas of passivation or passivation that have the potential to deform the shape of the sheet metal.
Metal deep drawing, which basically involves firmly holding both ends (opposite ends) of a metal sheet. The next step is to place the metal plate on top of a mold with a cross-sectional shape. Through a powerful punching process, the die creates a punch that pushes the sheet onto the machine. This helps develop the cross-sectional shape of the machine, deforming the sheet metal enough to meet the requirements. The drawing method can also be divided into two other processes called deep drawing and shallow drawing. These are all similar processes to achieve the desired depth on the sheet metal. For example, in a shallow drawing process, the radius of the main sheet metal will always correspond to the depth of the drawing, which means it will be equal. Deep drawing, on the other hand, is basically a cup cut in sheet metal to form different products. During deep drawing, the overall radius of the sheet metal is much smaller compared to the depth to which it will be carried out.
Metal extrusion is a typical process used by manufacturers to make products and parts in extruded shapes. The extrusion method involves a “closed die” manufacturing technique. In this case, the sheet metal is used as a whole, or extruded into parts. The process involves two separate dies that are positioned gradually at each end of the sheet metal to form a coin shape. One of the biggest benefits of the extrusion method is that it is very efficient in making a variety of metal parts and products with different quantity tolerances. It is also a relatively straightforward technique that can quickly and reliably create deformations (usually permanent) on a product. This essentially makes the part or product highly resistant to deep physical wear and strong impact.
Sheet metal beading is another unique technique for designing raised surfaces in specific areas of sheet metal. Studs can be created using two different methods – through a die set or a machine. The beading method is primarily used to create parts and assemblies for a variety of different applications, depending on the complexity of the desired design and its form. For example, some of the best examples of components that use beading include metal coverings, hoods, engine casings, door frames, checkerboard steel plates, and the like.Beading techniques can be used on different metal surfaces, however, the most popular type of metal for this process is aluminum. This is mainly because the metal is very easy to work. Additionally, the material is durable and lightweight, two great features that help make the beading process more efficient and effective.
Metal stamping techniques are very useful when it comes to metal fabrication. That being the case, each process is mentioned in terms of technical complexity. For example, quick and straightforward processes such as blanking, or punching, are often referred to as the initial level of any project. These processes are then followed by other processes to form the finished product. All in all, metal stamping is an extremely important, future-oriented process that is vital to many industries. The process is used to make everyday consumer products, as well as larger components and parts used to make vehicles and other things.
