marco technologies in focus: DotJet

DotJet stands for classic dot dispensing. The marco DotJet valve jets one or more drops onto the substrate at the desired position, guaranteed to be reproducible in weight, shape and volume. The dispensing is generated solely by the movement of the needle. Through a controlled opening and closing curve of our valve unit, high- or low-viscosity drops (dots) are formed precisely in the right quantity, at the right time, at the right temperature. Precision - reproducible - at any time, repeated millions of times.

The geometry of the valve seat and nozzle is adapted to the respective dosing material and the task. Larger quantities, even lines, are created by successive dots. Our system keeps the distance between the dots constant at variable speed of the robot. Once again, this makes the small but subtle difference.
