Product Portfolio
  • Dispensing Systems

  • The dispensing procedure is one of the most complex tasks of the dispensing process and belongs to our core competence.

    We don't commit to just one dispensing method. We use dispensing systems considering material and dispensing tasks; always the best fitting volume!
      • Volumetric Piston Dispenser Dos P

      • Piston Metering Systems – precise, robust, durable

        The Dos P piston dispensers are volumetric dispensing systems designed to work with 1C and 2C materials. These dispensing systems are extremely accurate and offer a constant mixing ratio, which guarantees highest process reliability. The systems of the Dos P series are all based on a robust mechanical engineering principle and are available in different sizes and models. Their metering cylinders are perfectly dimensioned with regards to the required volume and mixing ratio. An added benefit for even higher process reliability is the fact that metering accuracy does not depend on temperature, pressure or viscosity of the casting resin. When 2C materials are used, the mixing ratio is kept constant by discharging both cylinders absolutely simultaneously into the mixing tube. As a result, reaction time, or pot life, starts at this very moment. The two components are mixed inside of the static mixing tube until they are absolutely homogeneous. The seal and the cylinder inside walls are cleaned with a rinsing liquid each time the piston strikes, which removes aggressive product residues. This effectively minimises soiling and wear and tear of machine parts. At the same time, the adverse effects of atmospheric moisture are kept at bay. A Dos P dispensing system is the best choice with regards to reliability and service life no matter which material is used, but particularly when applying abrasive dispensing media.

         Dos P: The Tried and Tested Classic

        The Dos P in its basic configuration already covers a wide spectrum of requirements and additionally offers several configurations for different volumes. Thanks to optional features such as valve monitoring, mixing tube heating, dispenser heating and the models "Alternating" and "Multi-Nozzle" this system can be adapted flexibly to any new requirement.


        Typical applications of piston dispensers:

        • Potting
        • Filling
        • Applying
        • Sealing
        • Bonding
        • Fastening
        • Coating
        • Protection against moisture, dust, mechanical 
          stress, heat management in the production of 
          electrical or electronic components, solar 
          photovoltaics, medical engineering, etc.


        Features of this model line:

        • Lifting mechanism with stepper motor and linear guide
        • Pneumatic control of input and outlet valve opening
        • Monitoring sensor for input and outlet valves
        • Monitoring sensor for cylinder filling
        • Inspection glass to check the rinsing liquid level
        • 100 % airtight design
        • Fast and easy maintenance
        • Unrivalled resistance to wear and tear
      • Alternating Piston Dispenser Dos P-A

      • Uninterrupted Large Quantity Dispensing

        The Dos P-A is the system of choice if large quantities have to be applied quickly. In this design, one cylinder pair is loaded while the other is discharged. This allows the output of large quantities of dispensing material in very short times. Filling time is no longer an issue. Therefore, this system is ideal for filling large quantities or applying long beads of sealants or adhesives (continuous dispensing).

        Typical applications of piston dispensers:

        • Potting
        • Filling
        • Applying
        • Sealing
        • Bonding
        • Fastening

        • Unrivalled resistance to wear and tear
      • Small-Quantity Dispenser Dos PM

      • High precision for small and micro quantities

        Dos PM, the metering and dispensing system for small quantities, includes all performance features of the Dos P model line, but is optimised for dispensing quantities between 0.005 and 0.04 ml, using 1C media. It is used for applying dots or beads, for filling, for dam&fill applications, and for encapsulating, e.g. chips on a smartcard leadframe.
      • Dispensers for Small and Micro Quantities Dos JetPMU | Dos Jet

      • Contact-free – Electropneumatic: Dos Jet
        Miniaturisation requirements also impact the metering and dispensing technology. As a result, we included the Dos Dot and Dos Jet metering and dispensing systems for smallest quantities in the nanolitre range into our portfolio. They deliver extremely high metering and dispensing accuracy and speed, offering contact-free application of casting resins. Opening and closing of the valves is controlled electropneumatically. To keep change-over times as short as possible, a plug&play principle is applied. The advantages of this system are clearly in the area of handling easy-to-process dispensing media at low shot frequencies.

        Contact-free – Piezo Controlled: Dos PMU
        For higher small and micro quantity dispensing frequencies or more forceful dispensing than the electropneumatically driven tappet can deliver, the Dos PMU dispenser is recommended. Like Dos Dot and Dos Jet it offers extremely high metering and dispensing accuracy and speed. Opening and closing of the valves in this case is controlled piezoelectrically. To keep change-over times as short as possible, the plug&play principle is applied here as well. Harder-to-process dispensing media are easy to handle for the piezoelectrically powered tappet. The permissible higher forces allow processing of dispensing media beyond the limits of electropneumatically controlled tappet drives.

        Dos Jet
        Typical applications of electropneumatic dispensers:

        • 1C potting and gluing in the nanolitre range
        • Dispensing quantity 1 to 500 nl (= 0.000001 - 0.0005 ml)
        • Dispensing frequencies of up to 280 Hz
        • Handles viscosities up to 2,000,000 mPas


        Features of this model line:

        • Direct valve control in 24 V DC
        • Adjustable piston dynamics
        • Interchangeable dispensing pistons
        • Designed for demanding industrial environments
        • Easy use and maintenance



        Dos PMU
        Typical applications of piezo controlled dispensers:

        • 1C potting and gluing in the nanolitre range
        • Dispensing quantity 1 to 500 nl (= 0.000001 - 0.0005 ml)
        • Dispensing frequencies of up to 3000 Hz
        • Handles viscosities up to 2,000,000 mPas


        Features of this model line:

        • Controlled via control unit or from a serial interface
        • Piezoelectrically controlled tappet
        • Designed for demanding industrial environments
        • Easy use and maintenance
      • Gear Pump Dispenser Dos GP

      • Gear Pump Dispensers – for special dispensing tasks;
        absolutely unbeatable


        The Dos GP systems are the first choice for applications requiring 1C, highly viscous, but non-abrasive and unfilled dispensing materials. As a result, these systems are the best for applying continuous beads. Their gear pumps operate on the principle of rotating volumetric displacement. The geometry of the gear and the number of cogs determine the metering output. The rotating speed precisely controls the metering output. This renders the dispensing process absolutely continuous and constant. These systems work fast and accurately – even on complex geometries of the workpiece component.

        Dos GP: Robust, fast, continuous, and constant, even with highinlet pressure

        Typical applications of gear pump dispensers:

        • 1C bead application
        • 1C sealing and bonding
        • Variable quantities, freely selectable
        • High flow rate


        Features of this model line:

        • Drive with position feedback
        • Inspection glass to check the rinsing liquid level
        • Pressure monitoring – inlet pressure
        • Pressure relief
        • Swivel needle
    • Material Preparation and Feeding

    • The formulations and characteristics of resins have a wide range. For proper handling of these materials and for best production quality, customized systems specifically tailored for the material handling are required. The Scheugenpflug AG product range offers an adequate solution for each one- or two-component dispensing material at viscosities ranging from 50 mPa to 1,000,000 mPa and more.
        • A90 C | A90 B | A90 T automated material feeding

        • Small, Compact and Space-Saving

          The models of the A90 family provide an entry into automated material feeding. These systems are also suitable for applications with a very low material consumption and for dispensing materials that do not place high demands on homogenisation, heating and evacuation. Suitable models and versions are available for various requirements. Where material is fed from standard cartridges, the A90 C system is the right choice. These systems work with compressed air, which presses onto the cartridge and feeds the dispensing material from the cartridge into the metering and dispensing system. At the same time, the piston of the pneumatic cylinder moves, which ensures smooth dispensing of the material. The operator is notified when the cartridge filling level drops below a defined minimum value and when it is empty. These systems provide a reliable, trouble-free supply of material at an affordable price.

           
        • A220 rugged material feeding units

        • Docking – Reliable, Clean and Free From Bubbles

          The rugged material feeding units A280 and A220 are used for highly viscous and – depending on the pump model – non- or highly abrasive dispensing media. The drum (hobbock, pail) is positioned on the hobbock drawer. After closing the safety door, the operator initiates docking via the controls. This lowers the vacuum barrel follower plate into the drum, where the follower plate attaches itself to the material surface quickly and of its own accord (< 5 min.) and without air inclusions. The material feed starts fully automatically. When the barrel is nearly or completely empty, a filling level sensor alerts the operator. The empty drum, complete with the disposable follower plate is discarded. This avoids the risk of introducing residual material into the drum when docking onto the next barrel with a new vacuum follower plate, as often happens when conventional rubber follower plates are used incorrectly. Two models are available: the A220 for highly-viscous, non-abrasive dispensing media, and the A280 for highly viscous and abrasive materials. The difference between the two lies in their feed pumps.

          A220: The reciprocating pump allows a continuous feed of nonfilled, non-abrasive, paste-like media. It pumps material at both its up and its down stroke, making the system simple and cost-effective.

          Equipment details:

          • SCP200 controller
          • Rugged and durable reciprocating pump
          • Patented vacuum barrel follower plate or conventional rubber plate
          • Vacuum system for barrel follower plate
          • Filling level monitoring with linear measurement system
          • Use of 20 l single-use drums or barrels
          • Safety door
          • Rack on castors
          • Ergonomic hobbock drawer with barrel centring unit

          Optional Equipment:

          • Models for 1C and 2C casting resins
          • Barcode scanner for barrel tracking
          • Air conditioner
        • A280 rugged material feeding units

        • Docking – Reliable, Clean and Free From Bubbles

          The rugged material feeding units A280 and A220 are used for highly viscous and – depending on the pump model – non- or highly abrasive dispensing media.

           A280: Only one side of the tried-and-tested piston pump comes into contact with material; the reverse side contains a flushing liquid to prevent abrasive fillers adhering to the seals. This gives the system an unsurpassed service life when feeding highly abrasive, paste-like media.

          Equipment details:

          • SCP200 controller
          • Rugged and durable double piston pump
          • Patented vacuum barrel follower plate or conventional rubber plate

        • A310 Self-Levelling Dispensing Materials

        • Homogenous and Bubble-Free – 
          Superior Quality for Self-Levelling Dispensing Materials


          The all-round system A310 simultaneously prepares and feeds the dispensing material, while temperature control helps optimise its viscosity. Evacuation removes any air trapped in the material already during preparation to ensure bubble-free dispensing. Circulation of the dispensing medium prevents sedimentation of filler materials to maintain the consistency of the dispensing material’s properties. The agitation and circulation intensity in these systems can be adapted to the material. A range of models and optional equipment provides the ideal features and equipment level for each application. Especially with highly-filled abrasive media, our systems offer an unsurpassed service life. With the Scheugenpflug SCP200, this system features a self-explanatory, by touch screen display easy to operate control unit.

           Typical applications of the A310:

          • Ideal for moisture-sensitive dispensing media or materials that must be processed under vacuum
          • Also suitable for chemically ultra-pure casting resins


          Model A310 60/20:  Ideal for a High Throughput

          With 60 l and/or 20 l tanks and one or two 250 cm³ piston pumps per component, the A310 60/20 meets the requirements for higher preparation and feeding volumes. Hose line routing, rugged pumps and simple pump replacement reduce maintenance requirements. For the most demanding vacuum dispensing applications, such as ignition coil potting, fast degassing and a fine vacuum system are available.
        • A310 TP 05L/01L For Small Quantities and Highly Viscous Material

        • For Small Quantities and Highly Viscous Material

          For dispensing and/or providing only small quantities (for example highly sensitive and/or expensive dispensing materials), the model A310 TP05/TP01 is the right choice. Vacuum generation here is by a diaphragm pump; in every other respect the system has the same performance features and equipment options as its bigger counterparts.

          Features of this model line:

          • Vacuum generated by diaphragm pump in
            the performance range up to 5 mbar final pressure
          • Material circulation
          • Correct heating of the material tank and of all
            machine parts in contact with dispensing material
          • Tank agitator for 5 l
          • Tank sizes 5 l and 1 l Top Tank
        • A310 TP Power for Higher ViscosityFor materials

        • Power for Higher Viscosity

          For materials that are too viscous to flow or fill the large 250 cm³ piston pump efficiently, the Top Pump version is the answer. Here the feed pump is integrated in the material tank. This configuration assists the pump in feeding the highly viscous dispensing material with its limited flowability into the dispenser after it has been evacuated or prepared. Also for lower preparation and feeding volumes, this model is a good choice.

          Model A310 TP20/TP05: Optional equipment of the series:

          • Vacuum generated by rotary vane pump in the 
            performance range up to 5 mbar final pressure
          • Material circulation
          • Correct heating of the material tank and of all 
            machine parts in contact with dispensing material
          • Tank agitator
          • Tank sizes 20 l and 5 l Top Tank

           
        • Barrel Agitator Station

        • Moisture and Bubbles in Large Drums – no longer an issue.

          Barrel agitator stations are used in applications with a high material consumption and – in combination with the material preparation and feeding system A310 – ensure a homogenous dispensing material with the right temperature. The electrically powered agitator station is equipped with a lifting unit, a filling level monitor and an optional vacuum controller and is ideally suited for stirring and heating liquid dispensing media. The 200 l barrel can be fully evacuated, allowing a comprehensive preparation of materials that are sensitive to moisture also from large barrels. Loss of material through damage from moisture in 200 l barrels – for example PUR – is therefore a thing of the past. The barrel agitator station, including agitation and filling times, is controlled directly through the A310. Where several functions are required, the barrel agitator station can also be operated as a stand-alone system with its own SCP200 controller. 

          Equipment, depending on model:

          • SCP200 controller
          • Vacuum
          • Lifting unit
          • Filling-level sensor
          • Two-hand safety control
          • Automatic stop of agitator motor
          • Regulator to infinitely set stirring speed
          • Mobile collecting tray (200 l)
          • Inspection glass with lighting

        • Vacuum Barrel Follower Plate for A220/A280

        • Ideal for Highly Viscous Materials

          The patented vacuum barrel follower plate has been developed especially for feeding highly viscous dispensing materials from a hobbock or pail. It is used in the A220 and A280. This patented synthetic plate ensures a fast barrel changeover through clean, bubble-free docking. Emptying the barrel almost down to the last drop, this follower plate also has an economic benefit.

          The vacuum follower plate is made of polypropylene (PP), which guarantees sliding and manufacturing characteristics that are convincingly supportive to the production process. In addition, PP has a superior surface compatibility with the most frequently used dispensing media. Unlike conventional barrel follower plate systems, it prevents air being trapped during docking, smooths the surface and ensures a constant material flow. Because the plate is a single-use item that is disposed of with the empty pail, the new material is not contaminated with dried material residue. This prevents flaws already at the beginning of the process chain. No expensive vacuum chamber is needed to evacuate the pail/hobbock and no manual venting is required. Should a container of the required size or material not be available, A280 and A220 systems can also be equipped with a conventional rubber follower plate.

          • VDS B Vacuum dispensing systems

          • Ultimate Economic Efficiency and Quality to Suit the Specific Requirements

            The vacuum dispensing systems from Scheugenpflug are equipped with a metering unit for 1C or 2C media and have been developed for economic volume production at ultimate quality levels. Process reliability in this case matters most, which is ensured through reliable dispensing and repeatability. To ensure bubble-free feeding of the dispensing medium one of the A310 preparation and feeding units is used. Powerful vacuum pumps evacuate the entire space around the component or components. This guarantees bubble-free and homogenous filling of the components to ensure the required dispensing quality even in the case of difficult dispensing tasks. In vacuum dispensing, the cycle time relative to the total volume to be evacuated – which is defined by the components – plays an important role. To meet this requirement in all types of dispensing tasks, a range of different models of vacuum dispenisng systems is available, both as stand-alone versions and for integration in a production line.

            The VDS systems are typically used for:

          • The Allrounder for a Broad Range of Requirements

            In electronics manufacture, flexibility is the domain of universal systems, which allow a quick reaction to product changes. The vacuum dispensing system Universal is ideally suited for flexible volume production of medium-sized and large workpieces. Whether you are facing demanding component geometries, complex dispensing programs or a wide range of different workpieces, with this system you are prepared for everything. The VDS U is usually equipped with three motion axes and an automatic cup position. The VDS U uses the UVISneo control unit.

            The VDS systems are typically used for:

            • Processing self-levelling casting resins such as 
              polyurethane, silicone, epoxy resin, oils, etc.

          • Power to make Time less of a Limitation

            Time can be a limiting factor for many reasons. This problem can be easily overcome with the vacuum dispensing system VDS P(ower), which is usually equipped with three motion axes, an automatic cup position and a multi-piston metering system (2- to 8-nozzles, depending on required performance; other sizes on request). In a single evacuation cycle, as many components as possible are processed at the same time. They are arranged in an even grid, so that one dispensing stroke processes several workpieces at once. This system is the perfect solution for potting or filling medium-sized or small components at very high production volumes – rapidly and at high quality. The control unit used in the VDS P is the UVISneo.

            The VDS systems are typically used for:

              The Dos manual work stations consist of modules of various performance scopes, which can be easily adapted to the process requirements and can be flexibly extended. Combining material preparation units and feeding systems with metering and dispensing systems is possible without limitations. The result is always an integrated high-performance dispensing work station. A perfectly tuned system is more efficient than stand-alone solutions, because in this case material preparation, mixing, metering and dispensing are all perfectly matched both to one another and to the medium. Basic models include a material preparation or feeding unit and a metering and dispensing unit on a stand. Controls for the dispensing system are already fully integrated. The preparation, feeding and dispensing processes are end-to-end designed by a single provider. At manual work places the entire system is conveniently started with a foot switch.
            • DesktopCell

            • Compact and optimised for simple gluing and dispensing tasks

              The DesktopCell is a compact, integrated solution for small to medium-sized batches and for prototype production. It unites all the advantages of a fully fledged dispensing cell and a small footprint. The functionalities of the SCP 200+ control unit are extensive, allowing to intuitively control the cell via touch screen. All information about the different metering and dispensing programs is directly programmed on the unit and stored there as well. The control unit communicates with the material feeding unit and controls both the dispenser and the high-precision 3-axis system with precision spindles. No matter what the application, be it dot dispensing, applying of lines or beads, or filling processes, all metering and dispensing tasks are perfectly reproducible. If there are more complex tasks to handle and the compact desktop system is still big enough for the job, it is possible to switch to a CNC-enabled Beckhoff control unit with UVISnano visualisation.

              The dispensing cell is typically used for:

              • Simple dispensing tasks
              • Dot and line dispensing, filling of work pieces under atmospheric pressure

            • Processes

                • Atmospheric-Pressure Dispensing

                • Dispensing, or filling, is the discharge of low-viscosity material into a substrate, such as e.g. a component housing.
                   
                  Filling is used when sensitive electronic components must be protected from external chemical, corrosive or mechanical influences. The dispensing media used for filling are the so-called low-viscosity casting resins based on polyurethane, silicone or epoxy.

                  The goal is to extend the assembly’s service life and to optimise its functionality.

                  Conformal Coating:
                  Instead of filling, conformal coating is often used to cover a surface with a thin layer of casting resin. This dispensing variant not only protects the element from external influences, but also increases the stability of delicate assembly parts.
                • Pre-Treatment

                • 1. Plasma Pre-Treatment
                  Plasma pre-treatment means cleaning and activating the surface of the substrate to provide optimised conditions for dispensing.
                  Goal : Correction of inadequate physical or chemical substrate surface conditions to guarantee optimised bonding between surfaces and casting resin.

                  2. Chemical Cleaning
                  Cleaning of electronic assemblies increases the durability of afterwards applied sealing beads or protective coatings. It helps to completely remove resin or activator residues, which would otherwise cause insufficient bonding or poor coating with resulting corrosion or functional failures.

                  3. Pre-Heating
                  Pre-heating is recommended for two reasons.
                  Firstly, the assembly is dried, which removes all moisture (e.g. condensated water).
                  Secondly, heating allows controlling the dispensing material’s viscosity. For example, viscosity can be kept low for longer.

                  4. Drying
                  Drying by heating or by applying compressed air removes condensation from the assembly. If moisture were to remain on the component, it might react unfavourably with the dispensing material (e.g. start foaming). Or, enclosed by the dispensing material, residual moisture can lead to corrosion and a resulting failure of the electronic component.
                • Vacuum Dispensing

                • Vacuum dispensing means metering and dispensing with self-leveling casting resins in a chamber with sub-atmospheric pressure (approx. 1mbar).

                  Application: The goal of the vacuum dispensing process is to eliminate any air and humidity present in the component before the dispensing process, so that hollow spaces can be completely filled with casting material. The dispensing media used are the so-called low-viscosity casting resins based on polyurethane, silicone or epoxy.

                  Goal: Bubble-free and consistent filling of components for safeguarding a very high dispensing quality and a brilliant high-voltage and insulating resistance.
                • Dabbing

                • The term dabbing is used for the application of high-viscosity media onto a component in single dots or lines (beads).

                  Dabbing is used when highly viscous pastes or adhesives must be applied onto the surface of a substrate. The dispensing media used are the so-called high-viscosity casting resins based on polyurethane, silicone or epoxy. They may contain fillers or additives.
                • Heat Dissipation

                • „Heat dissipation“ describes the application onto substrates of filled, thermally conductive dispensing media in dots or beads. They are placed between the heat generating electronic component and the heat dissipating housing or heat sink.

                  Thermally conductive pastes are used for electronic components which generate much heat. The dispensing material has special properties which help to channel the heat generated by the assembly into a heat sink (e.g. a housing with a large surface area).
                  The dispensing media used are the so-called high-viscosity thermally conductive pastes or adhesives based on polyurethane, silicone or epoxy. They often contain hard filler materials with jagged edges, which make them highly abrasive when used.

                  The goal is to effectively dissipate the heat from the electronic component in order to avoid its overheating.
                • Damming

                • „Damming“ describes the application of a bead of highly-viscous dispensing media onto one half of a substrate. The dispensing material in this case serves as either a sealant or a connector between the two halves of the component.

                  Damming with viscous sealants is used where electronic components must be protected from external chemical, corrosive or mechanical influences. For example, in housings of automotive control elements or in photovoltaic equipment. The dispensing media used are the so-called high-viscosity casting resins based on polyurethane, silicone or epoxy.

                  The goal is to extend the assembly’s service life and to optimise its functionality.
                • Vacuum Bonding

                • High-Quality Bonding of Delicate Electronic Assemblies Without Mechanical Stress.

                  The ever increasing miniaturisation requirements for electronic components need processing methods that exert the least possible amount of mechanical stress to prevent delicate parts from getting damaged during production. In recognition of this development, Scheugenpflug has developed its patented vacuum bonding process.
                  Thermal management is also becoming a key factor during production. When a heat generating electrical component or assembly is glued to a heat sink it is essential to prevent air bubbles from getting trapped in-between, as they would block effective heat dissipation. The thermally conductive adhesives must be spread evenly and without any gaps between the energy source and the cooler.
                  The fully automated vacuum bonding process developed by Scheugenpflug guarantees the seamless distribution of the dispensing medium across the surface of the part. Conventional methods use pressure pins to join the parts, which often damages e.g. the PCB. Vacuum bonding applies no local pressure at all to the component. Unnecessary stress is completely avoided. As a result, this production method causes almost no rejects at all.
                • Curing

                • The chemical reaction of the dispensing material is called cross-linking, hardening or curing. Polymers crosslink due to their inherent properties or by means of an added agent (hardener). The cross-linking process changes the consistence of the material.

                  Curing is involved
                  in all applications of the metering and dispensing technology. The most common curing methods use heat, ultra-violet light, moisture, oxygen (aerobic hardening) or simply the chemical reaction catalysed by an additive (hardener).

                  The goal, on the one hand, is to establish the ideal curing stage where all required properties are obtained (e.g. protection, adhesion, etc.). On the other hand, the aim is to optimise production cycles and cycle times.
                • Gluing

                • Gluing joins two or more parts to form a material bond. Gluing essentially comprises two work steps. Firstly, the application of the adhesive, then the joining of the parts (e.g. housing and cover).

                  Gluing is used when two parts need to be joined more or less permanently. The dispensing media used are the so-called high-viscosity casting resins based on polyurethane, silicone or epoxy.

                  The goal is to establish a resistant and durable bonding between two parts.
