Comprehensive range of liquid dispensing equipment from Intertronics

Intertronics have a range of benchtop robots which can be configured for automated dispensing, pick and place, screw-driving, track cutting, curing and the like. They can configure and customize those robots with benches, enclosures, conveyors and integration.

In conjunction with their technology partners Fisnar, Intertronics offer true leadership in benchtop robots. These are small robots with footprints approximately A4 in size and working areas of 200 x 200mm have all the functionality of large machines. Bigger versions cover 800 x 600mm with a Z-axis of 200mm. They are robust, fit for shop floor use and programming is simple, with dedicated dispensing software.

They are especially valuable in dispensing applications where adhesives, sealants, encapsulants, potting compounds, coatings, inks, paints, greases, oils, solder pastes etc may be accurately metered onto workpieces - dispensed from barrels or cartridges mounted on the machine z-axis, or remotely located and fed through a robot mounted dispensing valve. Beads, coatings or micro-dots are common. Metering and mixing equipment can be interfaced to dispense two part systems.

One popular application is the dispensing of form-in-place (FIP) gaskets onto a component, which then cures into a soft, sealing gasket. The bead must be the same diameter over its entire length, and so the dispense needle travel-speed must match the FIP gasket flow rate, even around corners in three dimensions. A robot can be programmed to do this, whereas a human would find it impossible. Entry cost is around £4,000 on the smallest – with larger equipment running right up to 800mm x 600mm machines.

Quick, accurate, reliable dispensing of micro-dot quantities of adhesives, greases, inks and oils is now literally “at hand” with the Tridak Micro-Dot™ from Intertronics which features a positive displacement thumb operated action with simple stroke adjustment for volume setting from about 0.003ml to 0.200ml enabling indefinite repetition with great accuracy, with a wide range of low-to-high viscosity fluids using Intertronics’ standard 10ml syringe barrels and smooth flow tapered dispensing tips to suit individual situations.

The latest development in dispensing valves is the Fisnar DV509. Intended primarily for medical applications this is a lightweight diaphragm valve designed for precise flow control of low to medium viscosity liquids on a continuous 24/7 basis. The PTFE diaphragm separates the wetted parts from the air supply and therefore it is ideal for dispensing cyanoacrylates, reagents, UV adhesives, paints, inks, solvents, glues, electrolytes, alcohol and other volatile substances. Variants with stainless steel and UHMW bodies/diaphragm are also available.
