All users who work with small quantities of liquid two-component synthetic resins need to take a look at plant manufacturer TARTLER’s current portfo- lio. And that is because with the LC-DCM dispenser attachment and the product differentiation of the MDM series you will find four innovative solutions for the efficient dosing and mixing of epoxy resins, poly- urethanes and silicone resins. Typical areas of appli- cation are prototyping, electro casting, adhesive ap- plication, as well as product development and RIM applications.
Last year in Au- tumn, plant manufacturer TARTLER brought its range of system solutions for the processing of small quantities of low-viscosity 2K plastics up to the latest standards with the re-engineering of its dosing and mixing system MDM 4. The new model in the table machine series MDM serves as an entry into mechanical synthetic resin processing. TART- LER thus now offers a total of four systems that are predestined for use in development departments, testing laboratories and in maintenance, repair and servicing workshops.
The dispenser attachment LC-DCM is equipped with a universal connection point for a number of ma- nual cartridge systems commonly available on the market. For all those minimal-quantity users who want to move away from hand mixing or who pro- cess cast resins or adhesives primarily for repairs, reworks or optimising surfaces with pneumatic dis- pensers, this represents a real innovation. And that is because it enables – and this is by no means a given – the dynamic mixing of resin and hardener. In practical terms, this means the LC-DCM TARTLER offers small-quantity users the quality ad- vantages of the dynamic 2K dosing/mixing technology known from in- dustrial series production.
This means that anyone who uses the multi-component or double-car- tridge pistols from Sulzer, Nordson, Ritter or other manufacturers and docks on the LC-DCM to mix resin and hardener can now look forward to homogenous mixing and impressi- ve output. Depending on the materi- al combination, the LC-DCM achieves a volume discharge up to 80 percent higher than when using one of the static mixers offered by the cartrid- ge or material manufacturer at the same configuration and pressure. TARTLER’s dispenser attachment was developed specially for extreme mixing ratios and high-viscosity dif- ferences in the materials. As a result, it yields significant benefits for all synthetic resin and adhesive proces- sors who need to apply small quan- tities in even volume flows and need to use the same materials in reworks as in series production while achie- ving optimal mixing quality.
Just a few weeks ago, TARTLER released its new, overhauled MDM 4 for all small-quantity proces- sors who want to move from manual to mechanical dosing and mixing of liquid polyurethanes and epo- xy resin. This successful model from the pioneering era of the company’s history received a thorough re-engineering and in the MDM line now embodies the entry-level solution for mechanical synthetic resin processing. The table device was designed in such a manner that the combination of the pumps allows output levels from 0.05 to 1.5 l/min to be configured – depending on the viscosity and mixing ratio of the components. The output is controlled by a potentiometer and dosing ratios from 100:10 to 10:100 are possible. The mixing head is a slim LC 0/2 from TARTLER’s portfolio with a rotating dispo- sable mixer that is driven by a flexible shaft. The drive technology centrepiece of the MDM 4 is a fre- quency-controlled electro motor. When selecting the containers for the A and B components, the user can choose between containers of 0.5 to 100 l. A 220 V connection is all that is required to put it into operation.
The next biggest sister model is the MDM 5, which can be designed with an output level of 0.05 to 1.5 l/min. It offers more features and a Siemens Logo control system with useful features such as shot time pre-selection and a pot time alarm. Small-quantity users can use this table machine for casting, spraying and foaming. In addition to a 220 V connection, a compressed air supply (6-8 bar) is also required to put it into operation. The machi- ne can be equipped with various container sizes, electrical stirrers, as well as heating units for con- tainers, hoses and the mixing head. The selection from various mixing heads in TARTLER’s product range provides a great deal of freedom in terms of the needs-oriented optimisation of the machine.
Finally, the top-of-the-range model in TARTLER’S compact machine range – the MDM 6 – offers even more functions. It is designed for maximum out- puts of 3.5 l/min, can be equipped with containers with a volume from 3.0 l to 100 l, and can equally be used for casting, spraying and foaming. It also offers additional functions – for example, a small and large recirculation of the components.
With the LC-DCM cartridge mixer and its MDM pro- duct range, TARTLER offers system solutions that cover almost all tasks that arise when dosing and mixing small quantities of liquid polyurethane and epoxy resins. The plant manufacturer thus bridges the gap for many users to the next higher dimen- sion of synthetic resin processing: While the LC- DCM is the perfect replacement for hand mixing, the MDM 4 represents the entry to mechanical 2K dosing and mixing technology. Building upon this foundation, the MDM 5 and the MDM 6 in parti- cular bridge the gap to the large multi-component systems of TARTLER’s NODOPUR series, which can also be equipped with volume flow control and ot- her options.
