Support for adhesives of different viscosity properties

A piezoelectric jet controller accurately controls piezoelectric components by means of voltage change. Therefore, users can change the parameters of the controller CPU to adjust the open/close speed of the valve to adjust the obtained desired dispensing condition.
Adjusting the valve’s open/close cycle (time) based on the viscosity property of adhesive materials can resolve problems that cannot be solved by mechanical dispensers. Through parameter setup, users can reduce bubbling and sputtering.
In general, as adhesive materials of lower viscosity diffuse (sputter) more easily, users can reduce ejection strength (voltage waveform) to inhibit diffusion. By contrast, users can increase torque as the screw releases to eject adhesive at one time for adhesive materials of higher viscosity.
This piezoelectric jet provides optimal cycle combinations based on adhesive properties. From low viscosity to high viscosity (including paste), it can realize one machine for all.
In addition, to inhibit bubbling, it is necessary to program the up and down linkage motions individually in order to minimize air intake when the linkage rises. This piezoelectric jet offers optimal programming based on adhesive properties. From low viscosity to high viscosity (including paste), it can realize one machine for all.pic_v2k.jpg
