Deep drawing is one of the most widely used processes in sheet metal forming. It is a production technique which uses flat material and converts this through several deep drawing steps into a 3D shape. In this blog we will provide a more in-depth explanation of deep drawing.
The basics
So, let’s start with a simple explanation of what deep drawing actually is. During the sheet metal forming process, a sheet metal blank is radially drawn into a forming die. This might sound a bit abstract, so in order to provide a bit more clarity we will first explain the concept of a forming die. A forming die is a manufacturing tool that presses materials into specific shapes, much like an industrial-size stencil. In short, deep drawing can thus be explained as a shape transformation process with material retention. Fun fact, the process is considered "deep" drawing when the depth of the drawn part exceeds its diameter. This is achieved by redrawing the part through a series of dies.
Advantages
This technique offers several advantages. It is, for example, equally suitable for industrial small-series and mass production. However, the biggest advantage might be that less material is needed compared to a solid base volume. Therefore, it is often also lighter in terms of weight. Now you may wonder, what exactly can be created by deep drawing? Cylindrical parts are obvious examples, but it is also possible to create other shapes. You might not realize it, but many everyday objects contain deep-drawn parts, some examples are items including batteries and electrical motors such as hospital beds and relaxing chairs. The cases covering the batteries and electrical motors are usually made out of deep drawn materials, so this technique is less abstract than you might think!
More information?
At KeyTec we provide this technology in single step processing or progressive dies processing for large volumes. A wide range of materials can be deepdrawn by us such as a variety of copper alloys, stainless steel alloys, specific Kovar alloys and Molybdenium. Interested to find out more about our services?
