The lamination of fiber composite woven fabrics is a key shaping and joining process used in aviation, yacht construction and the manufacture of drones. Of central importance here is the reliable metering, mixing and application of the polyurethane and epoxy resins required to consolidate the fabric films. The 2C processing systems of the MDM series from TARTLER have been specifically developed for this task. Depending on the design, they are suitable for the manual or semi-automated production of laminated lightweight components for ultralight aircraft, boat hulls and drone bodies.
In addition to the growing demand for small wind turbines, the boom in yacht building, the soaring popularity of ultra-light aircraft and the rapidly increasing demand for drones are opening up many new applications for laminating technology. The shaping and joining process is a crucial prerequisite for the production of lightweight fiber composite components for boat hulls, aircraft bodies, drone housings and rotor blades. Highly accurate and homogeneous metering, mixing and application of the polyurethane and epoxy resins required for impregnating and consolidating fiber composite fabric films is essential for the reliable and economical application of laminating technology. TARTLER has developed the devices and machines of the MDM series with the aim of enabling manufacturers and plastics processors to produce high-quality floor and deck laminates. These two-component systems, which are designed for small-volume applications, are currently available in four variants and offer a wealth of options for optimizing processes in manual and semi-automated laminating technology.
With the MDM 3, TARTLER provides the perfect entry-level system for equipment-assisted laminating technology. This compact dosing and mixing system already has an electric dosing pump and container connections for easy integration of the original containers supplied by the material manufacturers. Designed for the efficient processing of liquid 2-component synthetic resins, it achieves a material output of up to 0.7 l/min at a mixing ratio of 100:100. In practical operation, the output quantity depends on the viscosities, the mixing ratios and the hose lengths (1.5 – 5.0 m). Only a 220 V connection is required for commissioning the MDM 3; an external compressed air supply is not provided.
The compact MDM 4 tabletop unit allows the user to take the step from manual to mechanical dosing, mixing and application. The system can be adjusted to output rates from 50 to 800 ml/min by using different pump combinations and depending on the mixing ratio and viscosity of the components. It is suitable for the realization of dosing ratios from 100:10 to 10:100, whereby the output can be adjusted via a potentiometer. The MDM 4 uses a compact LC 0/2 from TARTLER as mixing head. Its rotating one-way mixer is driven by a frequency-controlled electric motor via a flexible shaft. For the containers for the A and B components, the user can choose between containers with volumes of 0.5 to 100 liters The MDM 4 also requires only a 220 V connection for commissioning.
For plastics processors who require variable output rates of 0.05 to 1.5 l/min in lamination technology and want more equipment functions, TARTLER recommends its MDM 5. This system can be used both stationary and mobile and allows the liquid polyurethane and epoxy resins to be applied by pouring, spraying or foaming. The Siemens Logo control offers numerous practical features such as pre-selection of the firing time, a pot life alarm and much more. The MDM 5 can also be equipped with different sized containers, electric agitators and various heaters for containers, hoses and mixing head. Also of special note: It can be equipped with different mixing heads from the large TARTLER range! In addition to the 220 V mains connection, the MDM 5 requires a compressed air connection (6-8 bar).
The MDM 6 is the top model in TARTLER’s compact system series. It can also be used both stationary and mobile, and is designed for outputs of up to 3.5 l/min. In addition to numerous other features and functions, its control system also offers the possibility of performing small and large recirculation of the components. The MDM 6 is also suitable for pouring, spraying and foaming. It can be operated with containers with volumes from 3.0 l to 100 l.
With the systems of its MDM series, TARTLER offers four innovative solutions for dosing, mixing and applying small quantities of liquid polyurethane and epoxy resins in the context of laminating technology. Since all units are also integrated into the modular range of the German plant manufacturer, they can be optimally adapted to changing requirements with numerous add-on components – for example, with chassis, refill kits, and heating and degassing systems. In addition, TARTLER supports its customers through the entire journey to next level of mechanical and finally automated resin processing.
