Challenges in underbody applications:
The underbody is the base structure for other vehicle modules such as chassis or engine. Structural parts have to be securely joined using a mix of materials and technologies. The right application type is mandatory for a healthy work environment especially when combining technologies in body-in-white, for example when spot welding and adhesive dispensing are used. At Atlas Copco we have the technologies and competence to simplify the complexity of joining multi-material designs.
The optimization of the car body for stiffness and crash resistance is called structural bonding. In body shops, high viscosity adhesives are used to achieve those safe and reliable joints. Read more to find out which kind of application types the SCA product line is offering for structural bonding in body-in-white.
Most car manufacturers usually choose standard beads for traditional underbody applications. This is a preferred solution to achieve secure and reliable joints with adhesive when doing structural bonding. To achieve consistent beads and joints a combination of high repeatable accuracy and high productivity is needed – one that our SCA product line can provide.
Stitch bead application
Interrupted applications are very important when working with multiple technologies. In the underbody, spot welding or self-pierce riveting and adhesives are often used on the same part. By interrupting the application precisely, you can reduce issues like toxic fumes and waste of material. This is why stitch beads are popular among the OEM’s. SCA products offer meters and applicators that can do the fast switching and precise interrupting necessary to achieve a perfectly interrupted application.
