At Verdugo Tool & Engineering, we specialize in precision sheet metal stamping for customers in a variety of industries ranging from aerospace to defense to medical to food and beverage. We work with many materials, including aluminum, stainless steel, steel, and many alloys. Our third-generation, family-owned business is ISO 9001:2015-certified and ITAR-compliant.
Embossing is one of many stamping operations we perform. Learn more about it, our embossing process, and some of the benefits and applications for this widely-used operation.
About Embossing Sheet Metal
Embossing is a metal stamping operation performed with a punch and die to create a sunken or raised feature where both sides of the material are offset. In an embossing operation, the thickness of the material is not affected.
Embossed components can serve functional or aesthetic purposes. Functional applications improve the performance of the part such as increased stiffness, providing a mating surface, or marking weld points, etc. Additionally, logos or messages can be embossed into a part for marking, marketing, or aesthetic purposes.
What Is the Embossing Process in Sheet Metal Stamping?
Metal embossing is performed with a stamping press and specialized tooling. A piece of sheet metal is fed between upper tooling and lower dies. As the press closes, the upper and lower components move together with force, leaving an embossed impression on the material. This process can be used to add texture, functional finishes, or alter the visual effect of a piece.
Our embossing process follows these general steps:
1. Material Selection and Preparation
Embossing is compatible with many types of sheet metal including but not limited to:
- Aluminum
- Brass
- Copper
- Stainless Steel
Materials are selected based on their malleability and the specifications of the intended application. Before embossing, the metal sheet is cleaned and cut to the desired size.
2. Die Setup
Embossing requires a matched die set (i.e., male and female) that is precision-engineered with the desired texture or pattern. At Verdugo, we design and manufacture all tooling and dies in-house.
3. Pressing/Stamping Operation
The embossed feature is fabricated with the stamping press:
- The metal sheet is fed into the press
- The press closes, compressing the metal between the upper and lower tooling
- The tonnage of the press exerts even pressure on the material, transferring the design to it
Embossed designs can be raised or sunken (also called debossed). Even pressure is critical to prevent tearing or warping of the workpiece.
4. Post-Processing (Optional)
Embossing is often one of several stamping operations used to create parts and part features. Once the piece is complete, the following finishing operations may be used to enhance durability or appearance, if specified:
- Anodizing
- Surface Coating
- Trimming
5. Inspection and Quality Control
Finished components are inspected to make sure they meet the requirements for dimensional accuracy, tolerances, and surface finishes.
The Benefits of Embossing Sheet Metal for Stamped Components
Embossing, and metal stamping in general, is an efficient and highly repeatable process which is ideal for medium to high-volume production. Here are some of the key benefits:
- Cost-effective. Once dies are created, they can be used for mass production for many orders.
- Durability. Embossed metal components are durable, and the recessed or raised design is permanent.
- Low material waste. Stamping uses material efficiently to create as many parts as possible from a single piece, which reduces scrap.
- High strength-to-weight ratio. Embossed aluminum parts retain the strength of the base material and are often used in aerospace applications, where weight reduction is critical.
- Precision. Stamping dies form the same part features on each cycle with minimal variation. It is an excellent way to manufacture high-precision components efficiently.
- Versatility. Stamping and embossing are compatible with many types of metal including aluminum, copper, brass, titanium, stainless steel, and others.
- Functionality. Embossed features add dimension and texture that can be purely decorative for functional (i.e., improving strength). It can also be used to add traceability markings and adding manufacturer’s logos to products. Deforming the metal with embossing also causes it to harden (i.e., work hardening), so embossing can also be used to reinforce or add rigidity to components.
Applications of Embossed Sheet Metal
- Aerospace. Used for metal plates and tags on aircraft, marks on panels or other components.
- Automotive industry. Used to mark identification numbers, visual elements, and other vehicle or part information on components and metal tags.
- Electronics. Can be used to create permanent markings on internal components and brackets inside devices, as well as decorative or informational markings on enclosures.
- Industrial applications. Permanent markings on equipment parts and tags can be embossed, along with adding texturized grips or knurled finishes. Embossing can also be used to strengthen brackets, clips, and other part features.
