Sheet Metal Stamping Process
The process of turning sheets of metal into a useful part or component is called sheet metal stamping. The metal is fed into a press, where the stamping tool, also known as a die, creates the desired shape. The die is pressed into or through the metal with tremendous force. The force used in the process is measured in tons.
Except for some specialized processes, sheet metal stamping doesn’t use heat. Instead, it is done with a cold-forming technique. Even though no heat is used, the part can come out hot because of the friction that’s created between the metal and the die from the force of the press.
There are basically only three components to sheet metal stamping—the sheet metal, die, and press machine—but any single part can require multiple steps to arrive at its final form. The following guide explains a few common processes that might occur during metal stamping.
Forming: Forming describes the process of transforming the flat metal into another shape by applying force. It is accomplished in one of several ways, depending on the design specifications for the part. With a series of operations, the metal can be altered from a relatively simple shape into a complex one.
Blanking: Blanking is the most basic technique and initiates when the sheet or blank is fed into the press where the die cuts out the desired shape. The resulting piece is called a blank. The blank may be the desired part, also known as a fully finished blank, or it may continue to the subsequent step of forming.
Drawing: Drawing is a more complicated operation and is how vessels or deep depressions are formed. Tension is used to carefully draw the material into a cavity to change its shape. Though the material might stretch while it’s drawn, technicians try to avoid stretching as much as possible to keep the material intact. Sinks, cooking equipment, and oil pans for vehicles are usually made with drawing.
Piercing: Piercing is almost the opposite of blanking, but instead of saving the blanks, technicians use the material around the outside of the punched area. As an example, think of cutting biscuits from a rolled-out circle of dough. During blanking, the biscuits are saved; during piercing, on the other hand, the biscuits are discarded, and the hole-riddled remains are the desired outcome.
In the stamping process, sheet metal is transformed into complex parts using highly specialized computer-aided drafting and manufacturing programs. Sheet metal stamping produces superior, resilient, heavy-duty parts quickly and efficiently. The results are so precise, they’re typically more reliable and consistent than manual machining.
The following industries use components that are created via sheet metal stamping:
Automotive
Renewable energy
Medical
Industrial
Aerospace
Hardware
Home improvement
This list is by no means exhaustive. There is a considerable demand for sheet metal stamping, and the range of industries that depend on it is vast.
What is Electrical Fitting & How it Works
Maybe you never thought about this issue seriously, but what happens if we don't have fittings?
(1) Easy to Connecting Conduit & Running Wire
If you don't have a bend or reducer on hand,you will be crazy.
We can't arrange the pipes and wires in a straight line for the whole house which is determined by the geometry.In most cases,it is necessary to turn at the corner and to arrange the wire under or on the wall such as ceiling lamp installed.
However,you need to repair part of the tube sometimes for it is damaged,but you can not replace all of them instead of repair part of a pipe.So the fittings can help you to do this.
(2) Protect Wires
Good quality conduit can be kept safe of your wire,but it need to match with nice quality fittings too.For example, If you encounter a 90° corner, there is no bend or related fitting on hand.When we run the wire directly and through the pipe, this may cause additional bending and pressure on the wire insulation layer,resulting in whitening of the insulation layer and faster aging.Once the insulating layer fails, there may be a risk of electric shock.
Moreover,a well-sealed conduit will reduce the probability of water and dust entering,which not only keeps the pipe clean, but also protects the safety of the wires.
(3) Easy to Pull the Wires
If you need to modify the direction or position of the previous wiring for some reason,and we supposed you do not have any special tools.It is the wrong way to pull the wire directly from the right-angle wire tube because this will damage the insulation layer of the wire during the process of pulling the wire,which may cause danger in some cases.Moreover, pulling the wire in this way is easy to get stuck and increasing in construction time.
But if you add fitting when you layout the wires in the early stage,it will be different.The inner wall of the high-quality fitting is smooth and will not damage the wire insulation. More importantly,fittings can make the wires have a certain angle inside, which makes it easier to pull out the wires.
We know that people may not pay much attention to the quality of fittings in most cases, especially when it comes to replacement and maintenance at home.
Considering the amount is very small,so you just go to the nearest mall or store to buy a replacement.Therefore,we recommend buy branded products and pay attention to the specifications.So that you will not worry about used for save your time and money.If you want to learn more about the manufacturing process and process of electrical conduit,we mentioned in the previous post, you can read the post named ‘How to Make an Electrical Conduit’ to learn about the manufacturing process of electrical conduit and how to quickly identify the quality of PVC conduit.As for fittings, because most of them are injection molding processes, the identification method is similar.
