3 key benefits of metal stamping for electronics components

January 9, 2023

Metal stamping is a fabrication process that involves using dies and presses to form the material into desired shapes. It’s a commonly utilized practice at companies that make electronic components. Here are some of the many reasons for its popularity in such applications.

1. Suitability for popular products containing electronics
Today’s society features an ever-growing number of consumer electronics. Whether those products are smart home devices or video game consoles, most include parts that are or could be made with stamping processes.

A Grandview Research report found that the global market for this fabrication approach exceeded $200 billion in 2020. However, the analysts expect a 3.8% compound annual growth rate from 2021-2025.

One suggested reason for the upcoming growth is the popularity of smartphones in so many regions of the world. The authors clarified that stamping plays a key role in components like antennas, as well as the phone’s frame and camera lens holders. The report also mentions how electronics used in the aerospace industry are often shaped with stamping.

In the automotive industry, the North American and European regions are among the areas most likely to see sustained growth over the forecast period, according to Grandview. Since many vital car parts have electronics in them, including spanning headlights and steering wheels, it makes sense why manufacturers will contribute to global stamping growth.

The versatility of this manufacturing process is undoubtedly a factor that will help it remain popular for the foreseeable future. Besides matching the needs of current products, it will encourage pioneering makers to think outside the box with bold innovations.

2. Compatibility with various client requirements
Another notable advantage is the flexibility to meet precise client needs. CEP Technologies handles metal stamping on carbon, stainless steel, aluminum and copper. Many of its electronic components go to the automotive industry. Some of those products must maintain a ±1/4 degree on a bend. The company stamps more than half a billion parts every year, despite having less than 75 employees.

The company’s president, Ken Kaufmann Jr., said CEP Technologies did not always have a significant segment of its business devoted to electronic components. However, that’s changing, especially with the transition to electric vehicles.

“We currently make a heat sink that is assembled on an infotainment unit that provides in-car Wi-Fi,” he said. “Our most recent project is a stamped component for switches in large-truck applications.” As cars evolve he expects the electrical componentry segment of CEP to grow.They will require battery contacts, shielding products, press-fit pins and customized precision metal stampings.

CEP is currently making a battery contact for a multinational OEM’s key fobs and a set of components for another automaker’s door-entry systems. “Keyless ignition systems that allow you to start your car from a distance just by pressing a button on your key fob are sensor-driven and need contacts and precision metal stampings in different forms,” he noted. “For one current project, we produce approximately 3.5 million units annually for door-entry systems.”

The assortment of projects helps illustrate how metal stamping is often a viable solution for projects that must adhere to exact specifications. That’s especially true if a client opts for custom metal stamping. Catalog parts come in predetermined shapes and sizes. However, custom-made parts can meet highly specific tolerances that standard versions may not.
