Perfecdos precision micro dispensing systems


Precision Micro Dispensing Systems

Perfecdos GmbH
is a technologically leading company from the Bavarian town of Oberhaching located just 15km south of Munich. Perfecdos specialises in solving individual and highly demanding dosing tasks by developing & manufacturing innovative high-performance micro dispensing systems that are used in all forms of industry for the application and filling of liquids of all kinds inline with clients exacting requirements and processes.

The cornerstone of the company is the PDos X dispense valve series - an electro-pneumatically driven jet metering dispense valve which, thanks to a special ventilation process, has a very harmonious, precise and above all, fast switching characteristics enabling the metering of low to high viscosity liquids in the low nanolitre range (from 1 nanolitre).

The development involved more than 17 years experience with designing electro-pneumatically and piezo-electrically driven jet valve metering systems. Our customers receive an uncompromisingly optimised product in terms of performance, reliability and usability.

The company's particular strengths lie in solving even the most demanding dosing/dispensing tasks without problems associated with alternative dosing systems available in the market, with their multitude of system components and inherent reliability issues. Perfecdos systems are designed with modest simplicity, user-friendliness and most importantly....reliability.

The product portfolio is constantly evolving to ensure we are always one step ahead of the constantly ever-demanding requirements of industry due to the progressive miniaturisation of production processes.

Our clients benefit from a total of over 30 years of experience in application consulting and find out how you can make your dosing process reliable and economical in the long term.

Our extensive know-how allows us to offer knowledge transfer as a service. We offer on-site specialist training for your employees.

We also offer a repair service for users of the Liquidyn P-Jet CT electro-pneumatic jet dispensing valve now owned & supplied by Nordson EFD. We can factory repair the valve to as new working condition at a considerable cost saving on replacement.

Perfecdos PDos X1 Micro Dispense Valve


Perfecdos VC1 Micro Dispenser Controller

Multiple Applications

The high quality micro dispense valves can dispense a large variety of low to high viscosity materials including SMT Adhesives, Anaerobic Adhesives, Super Glues, Cyanoacrylate Adhesives, 1 and 2 part Epoxies, UV Adhesives, Lacquers, Silicones, Greases, Oils, Weak Acids & Alkalis and Ethers to name a few.

The Perfecdos Non-Contact PDos X1 Micro Dispense Valve for instance, is capable of delivering up to an astounding 300 micro dots per second with consistent results.

Dispensing Anaerobic Adhesives

Anaerobic adhesives such as LOCTITE 648 can now be precisely deposited without contacting the part as a result of the newly developed PDos X1 AN Micro 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, Perfecdos has managed to overcome the natural tendency of the adhesive in this situation to cure. The PDos X1 AN has an industry proven service life of in excess of 100 million cycles.

Consistent Results in Summer & Winter

Perfecdos 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.  Heating also ensures that you get consistent results regardless of the ambient temperature - set the heating just above maximum ambient temperature in the summer and get consistent results all year round.

Easily Adaptable Technology

With and ever increasing demand for rapid micro dispensing across all industries, Perfecdos have created a niche product which actually works and is more cost effective than more complicated competing systems. Apart from micro dispensers for anaerobic adhesives, Perfecdos micro dispensers can also dispense high viscosity media such as filled epoxy resins, silicones, lacquers and greases, as well as low viscous media such as instant glues, solvents etc…

Benefits of using Perfecdos Dispense Valves over Piezo Dispensing Systems

Perfecdos systems utilise a simpler technology compared to Piezo Dispensing Systems, which means that…..

Perfecdos Micro Dispense Valves are much easier & simpler to use

Perfecdos Micro Dispense Valves are extremely cost efficient compared to Piezo Dispensing Systems

Perfecdos Micro Dispense Valves are more flexible to use (i.e. easy for the customer to adapt the valve himself to the process)

Perfecdos Micro Dispense Valves are more robust than Piezo Valves – The more complicated, the more things that can go wrong !!

Perfecdos Micro Dispense Valves are easier to trigger yourself - they can be triggered directly from a suitable PLC or through our own VC1 controller.

For all these reasons the Perfecdos is a more cost effective and optimised solution for precision micro dispensing application.
