A Deeper Look at Deep Drawn Stamping

Deep drawn stamping is a unique approach to sheet metal forming that involves drawing flat sheet metal into a die in a circular motion to create a variety of metal components. The name “deep draw”  refers to the unique metal components produced, which are generally wider and have more depth.

These depths are formed by redrawing the component through a series of dies, which reduces the width even further while increasing length. It is also common for components to be deep drawn partially to create various diameters throughout the part. This process is much more affordable in comparison to turned parts, which require more materials.

The tool and die industry relies on deep drawn components manufacturers to help them with the ability to create various shapes for the automotive, aerospace, and electrical appliance industries. With so many unique components and custom applications, several methods need to be applied to create the right deep drawn metal stamped product.

  1. Deep Draw Stamping by Beading and Threading

Beads often help to reduce material consumption in deep drawing operations. A step bead, or offset bead, works to force the deep drawn metal stamp to bend and unbend before the metal enters the draw die cavity. The main advantage of using step beads is the reduction in the material used, making it an economical and environmentally friendly process.

Conventional half-round beads are placed farther away from the deep drawn cavity than step beads, simply because the draw bead portion can become thin and weak if it is placed close to the draw punch cavity. This weak area can break during production and damage the die. To prevent metal from pulling off the draw beads during the deep drawing process, more metal is used to obtain the finished part geometry. This is a secure, proven method of deep drawn stamping, especially when performed by a reliable metal stamping manufacturer.

2. Piercing Processes for Deep Draw Stamping

When you need to produce long and thin components, forming threads into the component with a wheel and arbor is an easy task thanks to deep draw metal stamping. Every diameter thin and wide is possible with the piercing technique.

Bottom piercing is the process of cutting a round or shaped section of metal out from the drawn component. The ability to puncture metal creates more shaping opportunities for the tool and die industry, partnered with the process of coining, which includes displacing the leftover pierced metal for the formation of specific shapes in the component.

Side piercing places holes in the sidewall of the drawn metal component and allows for shape-changing, depending on the deep drawn component’s specifications. The possibilities with piercing are endlessly customizable when you work with deep drawn metal stamping professionals.

3. Deep Drawn Stamping with Curling

The curling process allows for metal to be rolled under a curling die to form a rolled edge on the component. This is the perfect method for creating a beveled edge. Once a pilot hole is created, a punch with a large diameter pushes through and increases the length of the metal component, and folds it underneath.

4. Reducing Excess Material with Deep Draw Stamping

When you need deep drawn components with more customized thinner walls, there are plenty of options available from trusted deep draw metal stamping manufacturers. Ironing, thinning the walls of the components, or necking, reducing a section of the component to a smaller diameter than the rest of the part. Being able to adjust the diameter of your metal stamped components walls allows for more options for customization.

Deep drawn stamping manufacturers also must be able to cut away metal that is necessary for drawing the part from the finished component. The ability to trim components with deep draw stamping is also an effective method to be applied.

5. Notches and Rib Forming | Deep Draw Stamping

When you need to create an inward protrusion in your deep drawn component, there’s yet another specific metal stamping method to be applied. The process of notching involves cutting a notch. For creating an outward or inward protruding rib on the deep drawn component, the appropriately named process of rib forming fills this need.
