Metal stamping has experienced a significant rise in recent years, especially in automotive, aerospace, defense, and personal electronics, to meet the increasing demand for intricate metal components in manufacturing. Practically, a compound annual growth rate of 2.8% is expected by 2027.
What is metal stamping? This article will explain metal stamping’s common methods and applications.
What is Metal Stamping?
Metal stamping is a process in the manufacturing industry that shapes flat metal sheets by blanking, punching, bending, piercing, coining, embossing, or flanging.
Before coming to this process, stamping technicians must design the tooling using CAD or CAM engineering technology. Precise designs will ensure clear punches and bends and optimal part quality. In addition, the design process of a 3D model undergoes complex and time-consuming experience due to including hundreds of parts.
With a completed tool design, manufacturers can then apply different machining, grinding, or wire EDM to finish their production.
What are the Different Methods of Metal Stamping?
To achieve different shapes in metal stamping manufacturing processes, we have different methods of metal stamping. Take a look at these methods that can serve the demands of complex designs in various industries, including consumer goods, automotive manufacturing, aviation, electronics, telecommunications, or food and beverage.
Progressive stamping
Progressive stamping is an automated metal stamping process for high volumes that can make complex parts with consistency and precision. This method uses various stations to perform different operations on the metal as it moves through the press.
A continuous feed of material moves through the press, with each press stroke accomplishing several operations simultaneously. Different stations are equipped with specialized die and punch combinations, each designed to carry out particular cutting, bending, or shaping processes.
Transfer stamping
Transfer stamping works quite similarly to progressive stamping, but it moves parts from one station to another by mechanical arms or robots. In addition, transfer stamping initially punches the material from the strip or sheet and then transfers it to the next station. This method of metal stamping is widely used in producing more complex and large parts that cannot be workable in single-station progressive presses.
Deep drawing
We employ deep drawing to shape sheet metal blanks into three-dimensional forms, normally cylindrical components like cups. This method is common in manufacturing automotive parts, kitchen sinks, and metal containers.
In this process, we place the sheet metal blank over a die and use a punch to draw the metal into the cavity. As the drawn part is deeper than its diameter, it is a deep-drawn component.
Compound die stamping
A compound die works as a stamping die in cutting and forming in a single press stroke. It can combine blanking, piercing, and bending into a single die set, suitable for making medium-complexity parts requiring medium-complexity level and reasonable precision.
Blanking
This essential metal stamping operation cuts sheet metal stock into a flat shape. Blanking requires a die and punch with sharp cutting edges to shear the metal into the expected shape. The parts that are blanked will be further processed in other stamping operations.
Punching
Punching helps create holes and cutouts in sheet metals. This process uses a specialized punch tool to force the metal into a die based on the desired cutout shape or hole. Punching is normally a part of progressive or transfer stamping, but it could be a standalone operation.
Coining
Coining metal stamping processes can create highly detailed features or patterns on the surface of a part with precision. This process compresses the metal between the punch and the die to shape an intricate design. Coining has various applications in adding logos or trademarks to metal stamping components.
Embossing
The technique of embossing involves raising an area on the surface of sheet metal using a machine or a die set. Embossing can be done on steel and other types of metals, but aluminum is the most popular material due to its high machinability, lightweight, and durability.
Embossing is applied in various industries, including car hoods, plates, engine housings, door frames, metal coverings, checkered steel plates, and the like.
What are the Benefits of Metal Stamping?
When working on customized components, lead time is also a considerable factor in addition to the quality. The advanced metal stamping technology can help you with these requirements, bringing you various benefits of getting your components.
Metal stamping is popular in various industries thanks to its quick production of both specialized precision components and single industrial parts.
- High Precision: Metal stamping ensures accurate parts with extremely tight tolerances.
- Process Control: The conceptualization of your component through finishing will control the whole process to generate assembly-ready upon completion.
- Cost Savings: Die used in metal stamping are cheaper to produce and maintain than those in other processes. Moreover, with a high production volume, metal stamping uses less machinery and requires fewer labors, thus reducing overall expenses.
- Production Volume: With a created die, metal stamping can work on high-volume production quickly and efficiently.
- Versatility: This technology will help you create various shapes and sizes for your components, from micro-stamped components to engine housings.
- Longer Runs: The progressive die stamping process employs continuous material feed, allowing long runs between material changes and tooling adjustments. This advantage enables the production of mechanical parts in a much shorter time.
- Fast Setup: The setup time for multiple processes in traditional fabrication and machining can be much less for the progressive stamping process that can be performed in one operation.
- Less Scrap: Progressive stamping encompasses different ways of modifying metal, including punching, coining, bending, and others, to make the desired end part shape. Most materials are used while minimizing scrap.
- Repeatability: The hard tooling die designs facilitate a high volume with no die degradation, ensuring part quality and fewer failed parts.
What are Metal Stamping Applications?
Because of its versatility, cost-effectiveness, and ability to work on large quantities of precise components, metal stamping is widely applied across various industries, including:
- Automotive Industry: The automotive sector uses metal stamping to manufacture brackets, hinges, body panels, chassis parts, and engine parts.
- Appliance Manufacturing: Washing machines, refrigerators, and ovens use metal-stamped parts for their panels, frames, and structural components.
- Electronics: Electronic devices and electrical equipment components that use metal stamping include connectors, terminals, contact springs, heat sinks, and various electronic housing parts.
- Power Generation: Important components for power generation equipment, including electrical contacts, transformer components, and generator parts.
- Construction: Essential to produce brackets, fasteners, hinges, and structural supports.
- Telecommunications: Telecommunications equipment, including connectors, and antenna brackets, use metal stamping in their manufacturing.
- Consumer Goods: Metal stamping helps in producing consumer goods like toys, decorative items, and kitchenware.
- Medical and Healthcare: Metal stamping’s ability to produce precise and sterile parts makes it ideal for manufacturing surgical instruments, medical devices, and implantable components in the medical industry.
- Energy and Renewable Energy: Metal stamping techniques are essential for renewable energy systems like solar panels and wind turbines.
