Size Deep

The Sheet Metal Deep Drawn Stamping Process is definitely a very challenging one

Today, one of the most challenging processes of manufacturing is Sheet Metal Deep Drawing.

Many factors that determine the success

There are many factors that go to determining the success of deep drawn stamping process. These include different aspects like: sizes, shapes and thickness. Thus, in order to be able to calculate the best manufacturing method, it is very important that individual variables should be evaluated carefully.

But irrespective of the factors that contribute to the draw quality, the most important aspect to this entire process is the smoothness of sheet metal flow.

Key elements affecting metal flow

During this process there are certain key elements that need to be considered. These are as follows:

The type of material that will be used and the thickness of the material: This process calls for the use of materials that are thicker. This is because such materials are stiffer and they can be better gripped in the process. Plus, materials that are thick have more volume and thus they can stretch longer distances during the process

The surface of the tool and the lubricant that will be used in the process: It is important to make use of die surface finishes and lubricants as these help in reducing the friction that exists between tool surfaces and the metal being drawn. This way, the materials can flow through the tools much more easily.

Blank size and shape: Metal flow can be restricted by shapes that are very large and blank sizes. Also, the ability of the metal to flow can be greatly affected by the geometry of the parts.

The punching speed must not be forgotten: It is very important to have the right punching speed as this is what will allow the materials to flow through the tool. If the speed is too fast, then this will result in corner cracking.

Draw Radii has to be of the right size: If the radius on the draw die is too big for the material to flow through, then this will result in crinkling and if it is too small, it will result in cracking.

Draw Ratio: This is the ability that the material has to flow or draw and this can affect the draw depth and size of any single draw.

Thus, it can be clearly seen that there are many factors that go to determine the Sheet Metal Deep Drawn  Stampings process.

Metal stamping manufacturers are noticing metal stamping  and pressings markets increasingly unforeseeable. The  metal pressing industry has received wild swings both up and down -- sometimes these swings happening within a calendar month. The variations in these industry  have been compounded by the uncertainty in the world  economy over the past three years.
