Adhesive bonding systems experience
offered
Through its experience of many different servo driven and hydraulic systems an adhesives bonding system supplier has is able to maximise reliability and reduce line downtime.
Bead Technologies said that the next generation of heated application machinery for dispensing difficult glues is now becoming commonplace in the automotive and packaging industries The company said too that most adhesives are viscous enough that they move through machinery in turbulent flow motion, rather than the laminar flow of water or oil

Inverter power sources serve robotic MIG welders
ABB has developed ARCITEC II, a new generation of IGBT inverter power sources designed specifically for the robotic MIG/MAG welding of all materials used in metal fabrication.
Flexible robotic welding cell takes larger pieces
A new modular, flexible robotic arc welding system is designed to accommodate larger workpieces, which can be welded in a fixed position.
Given that many of the common hot melt adhesives are also compressible materials, any metering technology that puts the glue under pressure must consider both these factors.
Bead Technologies has been involved in the installation of many such systems within automotive manufacturers.
The company told manufacturingtalk.com that through its experience of many different servo driven and hydraulic systems it has built up an extensive knowledge of flow control techniques to maximise reliability and reduce the downtime of most major brands of equipment.

A powerful software tool that gives robot welding engineers full 'off-line' control of the MIG/MAG process provides efficient 'off-line' welding process tuning to predict a wide range of results.
Self-clinching nut is 40% closer in thin metal
Now there is a self-clinching nut that can be installed in thin steel sheet down to 0.63mm and it can be mounted up to 40% closer to the edge of sheet metal than existing clinch nuts.
* practical viewpoint - in an example of a heated hose typically used with a polyurethane adhesive at temperatures approaching 100 deg C, most hoses consist of a high pressure outer with an insert of PTFE to prevent moisture ingress.
In a typical 1/2in hose the nominal bore would be 12mm, and the nominal bore of the inner liner would then be 9mm.
This reduces the cross sectional area to (PI x r x r) = 254.5mm instead of 530.9mm.
The area available for turbulent flow material is almost double, which in turn means that the pressure needed by the whole system can be reduced significantly.
If less pressure is required then less power is used, leading to lower energy costs, longer wear life on all the pressure resistive components such as seals and valves, and best of all a cheaper and more reliable process for the operator.
This detailed approach carries on through the whole machine, so whether Bead is providing a simple dispense valve for a packaging system or a whole pump system with robot and programming control, the company really does look at the whole system 'from the ground up'.
In some cases, GBP 8-10 on changing a fitting can be all that is needed to cure a system that has given problems for years.
A recent problem on the new Jaguar XF was cured in a matter of minutes by Bead Technologies, which tracked the fault down to a simple valve change.
Imagine what Bead Technologies could do for you.
If you have any adhesive dispensing equipment, why not ask Bead Technologies to have a look over it, free of charge, to see if there are any ways to improve your production uptime.
