Potting thousands of small components with a 2-part silicone required an automated adhesive dispensing system integrated with a table-top robot.

The complexity of the dispensing required multiple passes at different flow rates then a final pass to level the adhesive.

The adhesive dispensing system used was a GP8O  gear metering system with vacuum degas capability in the reservoirs. The gear metering provided accurate ratio while the vacuum degas stripped air from the adhesive in the tanks.

When metering two adhesives at the design ratio it is important the two fluids react the same to the applied force. If compression occurs in the metering the ratio will not be accurate.

Programming of the robot is intuitive and done with a teach pendant. No actual code or dimensions are needed.

Almost any potting application can be automated with the wide range of tables available. Either gear metering or piston metering systems can be incorporated into a complete, automated dispensing system.

The versatility of the system permits the potting of different products.
