Definition of Aluminum Stamping

Aluminum stamping refers to one of the processes in metal manufacturing that uses dies to create shapes and patterns on aluminum sheets and is often used to transform standard aluminum products into smaller parts.
Aluminum stamping is a flexible metal manufacturing process with a variety of available technologies. These technologies allow you to form aluminum sheets into any desired shape.

Types of Aluminum Stamping
Punching Aluminum
Punching is the process of making holes or notches in aluminum sheets using a punch and a die. It can accurately shape the desired shape on the blank aluminum sheet with high dimensional accuracy.

Embossed Aluminum
Embossed is another aluminum bending process where the metal sheet is placed between a punch and a die. The aluminum can be pressed into an L, V, or U shape. The embossing method is also categorized as an aluminum stamping method.

Aluminum Deep Drawing
Deep drawing is a process where tension is applied to create deep indentations in the surface of aluminum. This method presses aluminum into a cavity to create a deeper shape. Stretching can be a challenging process, so expertise is required to minimize deformation.

Embossed Aluminum
In the embossing process, you can create high or low profiles on aluminum. The tooling system stamps the desired design onto the metal. Embossing provides a high level of detail in the pattern/design creation.

Flanging Aluminum
Flanging involves using a tool to place a flange or flare onto the aluminum surface. This process is used to develop structural elements in stamped parts and/or to create undercuts.

Details to look out for in aluminum stamping
Stucking
Stucking is a common problem in aluminum stamping. Stucking is when the aluminum sticks to the stamping tool, causing defects on the part surface. Therefore, it is important to use the right grease and contamination-free tools. Other coatings such as titanium nitride can also be used on the tool to minimize the adhesion of aluminum to the surface.
Springback
Aluminum also has a higher springback rate than other metals when bending forces are applied to it. The part fails to retain the intended shape. To avoid this, you need to exercise a lot of control during the stamping process.
Wrinkling
Wrinkling is a major problem in the stamping process, especially during deep stamping. Wrinkling occurs due to compressive stress acting on the aluminum sheet. Wrinkling can be reduced by controlling the blanking pressure and optimizing the die design. In addition, wrinkling can be prevented by ensuring that the material is evenly distributed during the stamping process.
Tearing
Tearing is a splitting problem. It usually happens to aluminum sheets when the material is overstressed during the stamping process. To prevent this, the rate at which the material deforms must be well controlled. In addition, it is important to choose an aluminum grade with good elongation. You can also try to optimize the tool design to minimize tearing.
Tool Wear
Aluminum is a hard material that easily wears the tools used for processing. It shortens the life of the stamping tool. Using high-quality tool materials and applying a protective layer on the tool can avoid tool wear.

Application Scope of Aluminum Stamping
Aluminum stamping parts have the advantages of easy handling, light weight, and high mechanical strength, which are very suitable for aerospace, aircraft parts.
