The final assembly process involves various dispensing applications, each with unique requirements. Key requirements include precision and control, material compatibility, adherence to safety standards, efficiency, environmental resistance, and rigorous quality control. Glazing, for example, needs precise adhesive application for secure glass integration. Trim parts require flexible adhesives for a perfect fit and finish.
A diverse dispensing portfolio with the right system options is essential for high application quality. At Atlas Copco, we collaborate with OEMs and Tier suppliers to develop customized solutions, ensuring we meet the specific demands of each application and enhance efficiency and quality in the final assembly process.
- Glazing
Glazing involves the installation of windows and windshields, which must meet high standards for clarity, strength, and sealing. The adhesive application ensures a secure fit, weather resistance, and contributes to the vehicle's structural integrity.
- Sun roof
The sun roof installation requires precise adhesive application to ensure a watertight seal and smooth operation. It must also meet aesthetic standards and integrate seamlessly with the vehicle's design, providing both functionality and style.
- Trim parts
Trim parts, including moldings, badges, and decorative elements, require accurate adhesive application to ensure they remain securely attached under various conditions. This process enhances the vehicle's appearance and contributes to its overall durability and quality.

Shaped bead application with RTVision.3d in final assembly
Our vision solutions support you with high quality shaped bead applications
Glazing applications in final assembly
Challenges in glazing applications:
The increasing size and quantity of windows demand secure glazing applications. The bonded joint must protect against water, absorb vibrations, and add strength to the car structure. Atlas Copco provides technology for reliable triangular bead shapes.
Our application solutions:
Shaped bead: Ensures even adhesion and 100% sealing to prevent water leakage. Used with 1K, 1K accelerated, or 2K adhesives.
One component (1K): Suitable for consistent ambient conditions, ensuring fast curing and reproducibility.
1K accelerated: Faster curing with an additional acceleration paste, reducing the time the module needs to be fixed to the car body.
Two components (2K): Reduces cycle time with high dynamic application, adjusting material flow for fast production.
Shaped bead for glazing and sunroof applications
Sunroof applications in final assembly
Challenges in sunroof applications:
Sunroof applications require well-sealed joints to prevent water leakage and corrosion. Atlas Copco provides technology for reliable, strong joints with consistent quality, and fast switches between 1K and 2K applications to extend uptime and lower costs.
Our application solutions:
Shaped bead application: The glass panel is mounted to a module frame using an accelerated polyurethane shaped bead, ensuring even adhesion and 100% sealing to avoid water leakage. Our SCA product line offers dynamically adjustable mixing ratios to lower process costs.
Mounting of the sunroof into the car body: The finished sunroof module is mounted to the car body using the same material for a reliable structural bond. Our SCA product line’s piston meter technology ensures high speed, repeatability, and continuous quality.
Application on a car antenna
Trim part solutions in final assembly
Challenges in trim part applications:
Trim parts like spoilers, bumpers, front ends, tailgates, and antennas are often thin plastic but must be mounted solidly to withstand vibrations and adversities.
Our application solution:
Creating reliable and invisible joints is crucial. Thin plastic parts are sensitive to temperature and can easily deform. Atlas Copco’s SCA product line offers dynamic mixers for perfect 2K adhesive mixing, reducing material consumption and increasing process speed and safety. Using 2K adhesives requires controlled material flow and precise mixing ratios to prevent unwanted curing. Our flexible metering system controls each component's flow, and our hybrid peltier technology with water-cooled hoses ensures consistent quality, even in hot climates.
