Deep draw metal 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 components involved, which are generally wider and have more depth.
These depths are created by redrawing the component through a series of dies, reducing 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 reduces costs in comparison to turned parts, which need 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 product.
Deep Draw Stamping with Beading and Threading
Beads often help to reduce material consumption in drawing operations.
A step bead, or offset bead, works to force the metal to bend and unbend before the metal enters the draw die cavity. The main advantage of using step beads is the reduced material consumption they can offer.
Conventional half-round beads are typically placed farther away from the deep draw stamping cavity than step beads. This is 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 manufacturer.
Piercing Processes for Deep Draw Stamping
When long thin components are needed, forming threads into the component with a wheel and arbor is an easy task thanks to deep draw metal stamping. Everything from the widest to the thinnest diameter is possible with this product.
Bottom piercing refers to cutting a round or shaped section of metal out from the drawn component. The ability to puncture creates more shaping opportunities for the tool and die industry and partners with coining, which includes displacing the metal for the formation of specific shapes in the component.
Side piercing places holes in the sidewall of the drawn component and allows for shape-changing, depending on the deep draw component’s specifications. The possibilities with piercing are endlessly customizable when you work with the right deep draw metal stamping professionals.
Deep Draw Metal Stamping with The Curling Method
Curling allows for metal to be rolled under a curling die to form a rolled edge on the component.
This is perfect for creating a beveled edge. Once a pilot hole is created, a punch with a large diameter pushes through and causes the metal to increase in length.
Deep Draw Stamping Methods for Reducing Material
When you need a component with a more customized thinner wall, 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 stamping components walls allows for more customization.
Deep draw stamping manufacturers also need to be able cut away metal that is necessary for drawing the part from the finished component. The ability to trim with deep draw stamping is another effective method.
Notches and Rib Forming
Creating inward protrusions is another common need in deep draw stamping.
The process of notching involves cutting a notch. For creating an outward or inward protruding rib on the part, the appropriately named process of rib forming fills this exact need.
