Precision Metering and Mixing Dispensing

DOPAG is one of the leading manufacturers of metering and mixing systems for multi-component media such as polymers and epoxy resins as well as single-component media such as silicone, greases, oils or adhesives. The high-quality standards of DOPAG products guarantee maximum precision and repeatability of results – even in highly automated processes. With the capabilities to offer a variety of application techniques – Shot, spray, continuous, or dot.

DOPAG’s 1K metering systems precisely deliver media such as adhesives, sealants, greases, and oils from their original containers to the application spot, where the material is then applied to the workpiece either shotwise or in a continuous bead shape. One-component media may be delivered via either a material pressure vessel, in case of a flowable or low-viscosity medium, or a drum pump installed on a double pump station for middle to high-viscosity media. The application is carried out manually or automatically.

The weight reduction and versatility of new adhesives are two of the major reasons bonding has become so popular in various industries for joining otherwise disparate materials and for the improvement in sealing techniques. DOPAG has been able to assume a leading position on the market because of its constant optimization of its systems. They apply adhesives both precisely and in the correct amount. This saves a lot of otherwise wasted adhesive or sealant and also provides an optimal visual result.

DOPAG’s 2K metering and mixing systems are capable of processing multi-component media such as epoxy resins, polyurethanes and silicones. Different basic configurations featuring a modular design are available and may be configured specifically to your demands. Homogenous mixing of the components becomes extremely important when processing multi-component materials. Wide differences in media viscosity, short pot life, components that are difficult to mix, and so forth require different mixing systems.

DOPAG offers dynamic mixing systems, static mixing systems, a static-dynamic mixing system as well as mixer element monitoring for static-dynamic mixing systems. DOPAG is the system provider for gasketing, bonding, sealing, potting, and automating. The dynamicLine is based on the newly developed dynamic mixing head with its innovative valve technology. With this technology, DOPAG has raised the bar and set a new benchmark regarding ease of use, accuracy, and reliability for dynamic mixing. The high-performance mixing head is based on 40 years of experience with two-component low pressure metering and impresses with its unique valve technology with booster. The variability of its DOPAG’s potting systems means they achieve all requirements for a precise mixing, metering and application of resins, always aligned to the individual requirements of customers.

DOPAG’s systems will deliver on all your mixing and metering needs no matter your market: automotive, aerospace, transportation, glazing, wind power, white goods, LED, construction, or electronics. Moreover, they will save on time, effort, and materials, and will help increase your ROI.

1K metering systems

Dopag 1K metering systems handle precision industrial applications of adhesives, sealants, lubricants or silicone with ease.

Dopag Coredis


Coredis, a gear metering system, processes special, low-density 1K epoxies filled with micro hollow spheres. The unique challenge in this case is that we are dealing with a reactive medium that remains in the material contacting systems after processing and that can be subjected to a curing reaction. In order to prevent the stored medium from unintentionally curing, Coredis features a specially developed structure.

Dopag Modis


A highly dynamic, speed-proportional gear meatering system, Modis controls the flow rate of single component adhesive applications in the automotive industry, as well as in the automotive supply industry. Modis covers a wide range of flow rates with just four different construction sizes.

Dopag Vectodis


Vectodis, a single action-acting piston pump, is also known as a “differential piston pump.” The modular construction of Vectodis enables a wide range of use. This product line is especially recommended for materials that need to be applied in a highly precise and repeatable manner. The material can be processed by either shot dispensing or continuous flow.

Consider the the various automotive components the 1K systems will lubricate:

  • Engine, gearbox, interior, body, exterior, chassis, powertrain, parts
  • Drum pumps, pressure vessels, transfer pumps
  • Pressure regulators
  • Dispensing valves, metering valves
  • Control units

Additionally, the 1K system bonds and seals the following areas:

  • Engine, gearbox, clutch
  • Dosing system with drum pump
  • Gear pump system
  • Gear and piston metering system

2K metering systems

DOPAG’s 2K system, which processes multi-component media, utilizes several systems. Four of the most popular are Eldomix, Vectomix, and Variomix, and Volumix.

Dopag Eldomix


The Eldomix 100/600 models of metering and mixing systems are compact, solvent free, and gear-pump driven. They are used to apply low to medium viscosity multiple component materials such as epoxies, polyurethanes and silicones.

Dopag Vectomix


Vectomix, a piston metering system, handles multi-component materials and is especially recommended for materials that need to be applied in a highly precise and repeatable way. Its modular construction enables a wide range of use.

Dopag Variomix


Variomix, a pneumatic-driven piston pump-type metering and mixing system, handles low to high viscosity multi-component media such as epoxy resins, polyurethanes or silicones.

These three systems can be used in the automotive industry for a number of purposes:

  • Encapsulating electronics and stators
  • Sealing electronic and cable housing
  • Bonding lightweight components, sheet metal, and battery housings
  • Processing thermally conductive materials, stator encapsulation

They also produce Automatic Dynamic Mixing for:

  • Gasketing, potting and bonding for battery of e-mobility, door panels, and loudspeakers
  • Dynamic mixing heads
  • Linear robots/industry robots

Automated Dispense Applications for Aerospace

Dopag Volumix

Finally, Volumix is suitable for automated applications of light polysulphides in the aerospace industry and can be used to seal virtually all aircraft components. The applications for sealants are many and varied.

  • To fill gaps in the assembly process
  • To protect against corrosion, e.g. Sealing of rivets
  • To seal fuel tanks and wings
  • As aerodynamic seals, e.g. on the outer skin and window frames
  • To seal edges (to avoid the annealing effect in fuel tanks)
