How EVs Are Changing the Stamping Industry

Posted by tmswebsiteadmin on | Leave a Comment

Increasing demand for electric vehicles necessitates the development of more complex and precise techniques for manufacturing battery components and other specific parts. For instance, the need for precision and uniformity requires the use of sophisticated stamping methods and equipment.

Another significant change is the increased demand for lightweight materials and components. EVs have a greater range due to lighter battery packs and body parts. This leads to the exploration of new materials and alloys — including aluminum and high-strength steel — that can be stamped into lightweight yet durable parts.

Lastly, the rise of EVs encourages more environmentally friendly production methods. This transition to electric power in vehicles reduces the transportation sector’s environmental impact. In addition, metal stamping companies are always looking for ways to reduce waste and energy consumption.

Metal Stamping EV Battery Parts

In response to the increasing demand for electric vehicles (EVs), metal stamping has taken on a larger role in vehicle manufacturing. It is utilized primarily in producing EV battery components and allows the precise production of these vital and intricate components. This is essential for the widespread adoption of EVs and the transition to a more sustainable transport system.

Metal stamping presents several advantages compared to other manufacturing techniques. These include cost-effectiveness, flexibility, repeatability, sustainability, and automation capability.

In this article, we will walk through the process of using metal stamping to create EV battery components.

EV Parts and Components for Metal Stamping

Metal stamping is a versatile fabrication process that can produce various EV parts and components, including structural, electrical, and body parts. Here are some examples:

  • Battery trays and brackets
  • Body and exterior parts (fenders, doors, hoods, and deck lids)
  • Chassis components (cross members, side members, and floor panels)
  • Electrical components (contactors, busbars, and terminals)
  • Motor and drivetrain components (gear blanks, cooling fins, and rotor and stator laminations)

Stamping Methods

Various metal stamping techniques have emerged over time, resulting in greater versatility and a broader range of applications. The most commonly used methods are as follows:

Progressive Die Stamping

Progressive die stamping involves a series of stations that perform specific operations on a metal coil, resulting in a finished part. This cost-effective, efficient, and precise method is used to create complex EV battery components like trays and brackets.

Transfer Die Stamping

Transfer die stamping works by separating the workpiece from the strip and transferring it mechanically between operation stations. This method is ideal for large-scale production runs because it allows the high-speed, high-volume production of EV components with tight tolerances.

In-Die Tapping

In-die tapping is a metal stamping technique that enables the formation of threads within the die itself instead of as a separate operation. This method can create threads on EV battery components like terminals and connectors.
