ACCURATE DISPENSING OF ADHESIVES IN QUANTITY

Now available from Intertronics, applications are envisaged within micro-electronics, medical optics, LCD/LED/OLED, bio-science and a wide range of general industry where processes call for exact quantities of even fragile materials to be metered, mixed and dispensed. Genuine volumetric, low shear dosing is achieved which is viscosity and primary pressure independent, in a pressure tight system without the need for a control valve. This enables a controllable dosing flow with suck back effect to ensure a clean cut-off and prevent post-dripping effects. The product features easy to clean continuous piston technology with precision drive rotor/stator for great accuracy and control to produce shot sizes from 0.03ml and with flow rates of 0.6 to 32ml per minute. The dual format set up pairs two pumps connected to one static mixing nozzle and may be linked for control purposes. This enables a wide range of applications to be addressed with control over dosing, dispensing time and mixing ratio – which can be adjusted from 1:1 up to 5:1. Operation of the controller is via an intuitive user guidance graphical interface plus an integral data exchange capability via USB connection. It accepts 0-20 bar input to produce 0-40 bar blended output with an accuracy of ± 1% and greater than 99% repeatability.
