Deep Drawing

Deep drawing is a common metal manufacturing method used to produce products from flat metal sheets.

This method is efficient when the depth of the produced part is significantly greater than the diameter of the metal sheet, hence its name.

Through deep drawing, a flat metal sheet can be transformed into a circular or three-dimensional product, depending on the desired shape and purpose of the product.

Metal processing is done at room temperature (without heating the material) and by applying pressure. In other words, a press machine is used to apply pressure to the metal sheet into a mold, giving the metal its desired shape.

The applied pressure can be hydraulic or mechanical. Hydraulic pressure has the advantage of maximum control over the metal sheet, allowing for simultaneous separate punching, while mechanical pressure provides a faster production rate.

Deep drawing enables extensive, high-speed, and precise manufacturing. However, it requires considerable skill because the applied pressure on the metal can lead to defects such as wrinkles or material fractures. Expertise in manufacturing ensures optimal pressure application, often in conjunction with the use of lubricants or other materials, to achieve accurate and high-quality products.

Applications:

Deep drawing is widely used for manufacturing a variety of products such as automotive parts, bomb casings, sinks, cans, pans, and more. The applications of this method continue to grow.
