Laser Wire Marking vs. Hot Stamping: What’s the Difference?

There are many different methods for marking products, but only some are suitable for wire-marking applications. For instance, engraving machines wouldn’t work well since the process destroys materials, which could damage the wires. However, there are two methods of marking that are very successful with wires—laser wire marking and hot stamping. Read on to learn more about the differences between these two processes.

HOT STAMPING

Hot stamping is a marking method that uses heat to transfer dried inks or foils onto a specific surface. A pre-engraved die or mold is heated by a hot stamping machine, then pressed down onto the object. The mold is highly detailed, allowing for accurate markings with clean edges.

Hot stamping with foils typically consists of three layers—a color layer, a release layer, and an adherence base. This combination of foils helps carefully decorate and mark various products. While hot stamping is usually used for decorating and personalizing products, it is sometimes suitable for wire marking applications.

UV LASER MARKING

UV laser marking machines utilize a concentrated beam that alters the surface of a specific material, creating a highly durable, indelible marking. Unlike an engraving or hot stamp, laser markings do not protrude or sink into the material; rather, the material surface remains flat.

This accurate and reliable method for marking is commonly used for wire-marking applications. Specifically, it’s a helpful marking process for industrial sectors where wires are exposed to extreme conditions, such as aerospace, defense, automotive, and more.

WHICH METHOD IS RIGHT FOR YOU?

As you can see, these two marking methods are quite different. Hot stamping adds imagery to material through heat transfer, while laser marking physically alters surfaces, producing indelible markings. Even though hot stamping is suitable for wire-marking applications, the durability of hot-stamped markings makes them a poor choice for certain industries. Therefore, if you require a marking method for sensitive wires in extreme environments, UV laser wire marking is the best process for you.
