Dispensing Technology for Bonding Components

In industrial bonding, components are joined together permanently, flexibly or functionally. Depending on the application, different adhesives are used, such as epoxy resins, polyurethanes, silicones, UV adhesives or cyanoacrylates. The dispensing process must be precisely matched to the material, component geometry and required bonding area.

With suitable dispensing technology, adhesives can be applied as dots, lines, beads or over larger areas. Uniform material quantities, clean application, the appropriate dispensing tip, the right dispensing valve and reliable repeatability are essential. For two-component adhesives, mixing quality, mixing ratio and pot life are additional important factors. Depending on the process, bonding can be carried out manually, semi-automatically or automatically using a dispensing robot.

Automated dispensing of one component adhesive

Shown in the video

Automated adhesive dispensing onto a plastic frame for bonding to transparent acrylic glass. The cartridge is mounted on an adjustable cross-slide on the WRA-500 dispensing robot, allowing the dispensing position to be easily adjusted manually. Material dispensing is controlled by an IG-1500D dispensing controller connected to the cartridge. This ensures controlled and repeatable adhesive application along the defined contour.

FAQ - Frequently asked questions about industrial bonding

A wide range of adhesives can be dispensed, including epoxy resins, polyurethanes, silicones, UV adhesives, cyanoacrylates and MMA adhesives. The appropriate dispensing technology depends on viscosity, reaction behavior, dispensing volume and the application.

For simple applications, dispensing controllers with cartridges and dispensing tips are suitable. For applications with higher requirements for repeatability, dispensing patterns or automation, dispensing valves, material pressure vessels, 2K dispensing systems or dispensing robots can be used.

A controlled dispensing volume ensures a uniform adhesive joint and a reliable bond. Too little adhesive can impair adhesion, while too much material can overflow, contaminate components or require additional cleaning.

Yes, two-component adhesives can be processed automatically using suitable mixing and dispensing technology. For example, the 2K-DOS mixing and dispensing system can be combined with a dispensing robot. This allows the mixing ratio, dispensing volume and dispensing path to be precisely matched to the respective bonding process.

A dispensing robot is useful when adhesive needs to be applied repeatably to defined positions, lines or contours. Particularly in series production, with complex dispensing paths or consistent components, a robot improves process reliability.

The quality of an adhesive bond depends on factors such as adhesive selection, clean surfaces, low-bubble material processing, dispensing volume, bond-line geometry and curing. Suitable dispensing technology ensures that the adhesive is applied evenly, cleanly and reproducibly.
