Surface preparation is essential to ensure the success of adhesive bonding. It involves optimizing the surface of the substrate for a stronger bond with the adhesive. There are three primary aspects to surface preparation: removing contaminants, roughening the surface, and modifying the chemical composition.
The rotor transfers power from the batteries to the wheels of an electric vehicle. Manufacturing rotors with the latest technologies improves the motor’s efficiency in many ways.
Fiber laser welding is a welding process that uses a laser beam as the heat source. As non-contact tools, fiber lasers are low maintenance and offer fast welding speeds. The laser beam is highly precise and has a low heat input, which minimizes damage to the material
To ensure that e-motors preserve their efficiency over time, manufacturers protect conductive parts from contaminants with epoxy coating. Laser cleaning can be used to remove epoxy before laser welding and to remove contaminants before applying epoxy, ensuring a clean surface in both cases
Laser welding needs to be controlled to detect bad welds and ensure quality. Ensuring good weld quality is getting more challenging, as laser welding is increasingly used for micro welding applications that demand more precision, like battery tab welding in the automotive industry.
We often think of the electrification of the industry as a movement away from fossil fuels to reduce global emissions. But there are other, less obvious implications that are affecting electric motor manufacturers and consumers.
Canadian company Laserax solidifies its presence in the European automotive industry by moving its German office from Bremen to Bad Krozingen.
The advantages brought by hairpin motors are making electric vehicles more competitive not only with previous generations of EVs, but also with combustion engines. They are more efficient, have a higher power density and thermal performance, and are simpler to manufacture.
Laser spot welding is a welding process that uses the power of a laser beam to join two metal surfaces at a single spot. Laser seam welding is when surfaces are welded over a long, continuous surface.
Wire bonding machines are widely used in the aerospace, semiconductor, solar cells, microelectronics, and EV battery industries. In this article, we’ll go over the types of wire bonders, discuss their limitations, and present how laser welding is used to overcome these challenges in the automotive industry.
In metal manufacturing, laser structuring is increasingly used to prepare surfaces for adhesive bonding and thermal spray coating, creating a surface texture that improves adhesion while removing contaminants that could interfere with it.
A wide range of surface processes are used in manufacturing to improve part surfaces. They can add material layers to a surface, remove undesired materials from a surface, reshape a surface, or modify the properties of a surface. In this article, we’ll go over different types of surface processes and technologies to learn which one is good for what application.
