Have you ever wondered how shapes of metal are manufactured? It is called sheet metal press machine. This accounts for pressing flat metals through a die with a unique machine to achieve different shapes and sizes. It does this by bending and forging the metal into a desired shape that we need. Nadun has special type of machines to produce accurate parts to multiple industry segments of automobile, aviation & buildings.
Forming shapes out of flat pieces of metal requires a great deal of skill and practice. When working with metal, we have a team of experts trained in a variety of methods to ensure the best results possible—this is what we do at Nadun. One of the major techniques of our training is known as air bending. This method simply uses a die, which is a contoured shape, and presses the metal into the die to form a bend. Air bending provides the opportunity to be flexible in our designs while still being accurate and true to the design. What I mean by this is that we can edit if necessary because the shape does not lose quality.
Other ways we utilize are through bottoming. In comparison, this method produces a tighter angle, or tighter bend, of the metal. But it is not as flexible regarding design changes as air bending. We also utilize a concept called coining. Coining is a very intensive process that deforms the metal utilizing lots of stress to ensure the shape is as desired. And, lastly, we have curling, which is bending the metal round, much the same way that you curl a piece of paper. As all the methods have their pros and cons therefore we have to select one of them very cautiously before starting a new project.
Just a slight difference in how the part operates can even lead to failure because being precise is crucial during sheet metal press forming process. At Nadun, we are using smart tools and unique computer programs to ensure everything is perfect from day one. We will design on the WriteOn, a computer model before we can make it. This is to help us program the machine so we can build a sample part for us to test it against. After we create this sample part we will measure this sample part with special tools to verify that it is correct and within all of our tolerances. When the sample is confirmed, full production will begin, which we supervise closely to ensure the right and accurate matters are done properly in every step.
Sheet metal has characteristics that we must keep in mind to form it into shapes. These are properties that describe how the metal tends to respond when pushed and pulled. Things such as the thickness, hardness, and ductility (stretchability) of the metal will affect how the press forming process operates. At Nadun we carefully check and monitor these properties of each piece of metal for desired outcome. For each project we conduct many tests and experiments to ensure we learn the best way to form the metals. That allows us to take advantage of the metal’s characteristics, assisting us in making robust and sustainable components that are functional as well.
We can apply a lot of designs and shapes on sheet metal press forming. This is a process we use at Nadun to help our clients brainstorm fresh design concepts. Using our numerous accurate processes (air bending, bottoming, coining, curling, etc) we can create distinctive shapes that satisfy the needs of our clients and meet them. We also utilize new software and tools to discover new design ideas that we weren’t able to do in the past. This helps us explore the limits of what we can do, giving us the ability to create unique parts.
