Advanced Dispensing and Sealing Robots and Cobots

GLOBAL builds robotic cells that dispense seam sealers, structural adhesives, RTV silicones, formed-in-place gasketing (FIPFG), polyurethane foam, cavity wax, sound-dampening materials, hem-flange sealers, and underbody coatings. The delivery method is engineered around each material's flow characteristics and viscosity, the required bead geometry, the cure process, and the part surfaces involved. Sharing the material and where it goes on the part lets GLOBAL match the dispense approach to the application.

Both single-component (1K) and two-component (2K) materials can be dispensed, with 2K applications requiring metering, mixing, and ratio control to combine the components correctly before they reach the bead. GLOBAL integrates the dispense equipment itself, including pumps, heated hoses, meter-mix units, and applicators, typically sourced from specialty dispense-equipment suppliers and tied into the robot and controls. The team can work with a customer-preferred or specified dispense supplier or recommend an appropriate system for the material and cycle time.

Bead consistency comes from coordinating robot speed with material flow along programmed 3D paths, with pressure and flow control tuned so the bead stays uniform through corners and contours. This repeatable, path-controlled application reduces the variation common in manual dispensing on complex parts. GLOBAL develops and validates the paths through simulation and process trials so the production cell reproduces an agreed bead rather than relying on operator technique.

Fixtures are engineered to locate each part securely and repeatably so the programmed dispense paths land in the same place every cycle. Presentation depends on part size and volume and can use dedicated nests, indexing tables, or conveyors, often with part-in-place checks that confirm a part is present and correctly positioned before the cycle begins. GLOBAL reviews part geometry and access early so the fixturing suits the surfaces and joints that need sealing.

Dispense systems need routine care to stay reliable, so the cell is designed with purge cycles, tip and nozzle cleaning, anti-drool control, and straightforward material changeover and refill. For 2K materials, keeping the meter-mix system purged and maintained is especially important to avoid cured material in the lines. GLOBAL sets these maintenance points during process development so upkeep fits predictably into the production routine between scheduled maintenance windows.

A dispensing cell can run as a stand-alone station or be integrated into an existing line, with GLOBAL handling controls, guarding, part flow, and any handoff to inspection. Where verification is required, GLOBAL frames it as a downstream vision check, a separate station that confirms bead presence, location, and continuity after application rather than a claim that the dispensing robot inspects its own work as it goes. The right inspection approach, camera, and lighting are determined during system design.

After installation and validation, GLOBAL trains operators and maintenance staff on running the cell, loading programs, clearing faults, and caring for the dispense system, and can recommend a spare-parts list covering applicators, tips, seals, and wear items. Because the company also provides automation staffing, manufacturers can access controls engineers, robot programmers, and technicians when deeper resources are needed. Ongoing support is available for troubleshooting, adjustments, and adding parts or materials to the cell later.
