In body-in-white sheet metal is joined to form the chassis of a car. The applied adhesive fulfills several functions, such as increasing crash performance, vehicle stiffness, and resistance against corrosion in hem flange areas. The requirements for body-in-white include ensuring optimal function, enhancing safety standards, minimizing noise, vibration, and harshness (NVH), and guaranteeing long-term durability. Depending on the joining task, there are several methods available to meet these stringent requirements. Atlas Copco is your perfect partner for high-quality and effective adhesive joining solutions in body-in-white.
- Roof structures
Roof structures are designed to meet high aesthetic and functional standards, including noise reduction and insulation. Made from materials like aluminum, steel, plastic, or carbon, each with unique properties, the challenge is to ensure a stable, durable, and high-performance structure.
- Framing
Framing joins the side walls with the roof frame and underbody, focusing on crash safety, lightweight design, and short production times. Customized bonding solutions enhance crash safety while minimizing weight.
- Closure parts
Closure parts like doors, hoods, and bumpers create stable connections between components, optimizing crash safety, vehicle rigidity, and corrosion protection. Seam bonding is a complex technique used in this process.
- Underbody
The underbody forms the basis for key vehicle components like the chassis and engine, requiring a strong structure. This is achieved by joining different materials using techniques like bonding and spot welding. Ensuring a safe and healthy working environment is crucial.

- Sealing applications
- Hem flange bonding
- Anti-flutter applications
Structural bonding applications in body shop
Challenges in structural bonding applications:
Structural bonding connects load-bearing car parts using adhesives, enabling even load distribution and weight reduction. It increases rigidity and crash safety by absorbing impact energy, crucial for modern lightweight automotive constructions. Applications include underbody protection, framing, and bonding of add-on parts.
Our application solutions:
Bead application: Adhesives are applied in even, elongated beads for precise, controlled bonds on large surfaces or longer joints, ensuring structural strength and rigidity.
Stitch bead application: Adhesives are applied selectively or in intervals, reducing adhesive use while ensuring strong bonds at critical points. This method improves curing and bond flexibility under dynamic loads.
Swirl application: Adhesives are applied in a circular or spiral pattern, ideal for covering larger areas quickly and ensuring a uniform layer. This method is useful for bonding surfaces with irregular shapes, providing strong and consistent bonds.
Multi-Dot application: Adhesives are applied in small dots across the surface, allowing precise control over placement and quantity. This technique reduces waste and ensures strong bonds at critical points, ideal for high-precision applications.
