LIQUIDYN
are specialists manufacturers of Non-Contact
Micro Dispensing Systems, designed for applications where accurate
and repetitive volumes of material need to be dispensed in volumes
ranging from 10 nanolitres and up either as repetitive micro dots, beads or
fixed volumes.
The high quality micro
dispense valves can dispense a large variety of
low to high viscosity materials including SMT Adhesives, Anaerobic
Adhesives, Super Glues, 1 and 2 part Epoxies, UV Adhesives, Lacquers,
Silicones, Greases, Oils, Soldering Fluxes, Weak Acids & Alkalis and
Ethers to name a few.
The LIQUIDYN Non-Contact
P-Dot Micro Dot Dispensing Valve for instance, is capable of delivering up
to an astounding 360,000 micro dots per hour with consistent results.
Anaerobic adhesives such as LOCTITE
648 can now be precisely deposited without contacting the part as a
result of a newly developed P-Dot AN Micro Dot Dispensing Valve. The new
valve applies the adhesive by projecting a small drop over a distance of
up to several millimetres (Jetting) between nozzle exit and work piece
creating uniform and repeatable micro dots of adhesive on the part with
no splatter.
The main problem in the past, when jet dispensing anaerobic adhesives
(i.e. Super Glues), was the fact, that when an anaerobic adhesive comes
into contact with metallic valve components in the anaerobic conditions
found inside the valve, this would lead to the rapid hardening of the
adhesive in the valve rendering it useless. With clever material
selection for all wetted parts and careful design of all dynamic parts,
LIQUIDYN has managed to overcome the natural tendency of the adhesive in
this situation to cure. The P-Dot AN has an industry proven service life
of in excess of 100 million cycles.
LIQUIDYN Micro Dispense Valves can be heated for use with viscosity
sensitive materials to aid consistency in the dispensed end product and
closed loop sensors can be added to detect the drop being ejected to
verify the dispense has been carried out.
With and ever increasing demand for rapid micro dispensing across all
industries, LIQUIDYN have created a niche product which actually works
and is more cost effective than more complicated competing systems.
Apart from dispensing anaerobic adhesives, LIQUIDYN dispensers can also
dispense high viscosity media such as filled epoxy resins, silicones,
fluxes, lacquers and greases, as well as low viscous media such as
instant glues, solvents etc…
