Adhesive beading in the electronics industry

Dispensing 1K adhesive sealant DOWSIL™ 7091 with needle dispensing valves

In greenhouses, the temperature and humidity are usually high. Special LED luminaires are often used there. They have to cope with these ambient conditions. Therefore, it is important to reliably bond the housing of the luminaires to protect the electronics inside. 

DOPAG has configured an automated dispensing system especially for this application for a leading manufacturer. An XYZ robot was equipped with three needle dispensing valves from DOPAG. This allows the 1K adhesive DOWSIL™ 7091 to be applied to three enclosures simultaneously in bead form. The company thus benefits from high accuracy and reproducibility as well as reliable bonding with a long service life. Last but not least, this solution allows higher quantities to be produced in less time.
