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.
Medical equipment, building and construction, automotive industry,
electronics industry, and many more.
