Compact, mobile, reliable and easy to operate

The mobile workstation for processing and dispensing of highly filled, abrasive and highly viscous LOCTITE 2K epoxy structural adhesives

 

The DM 80 STATIC MIX is designed to be used in various industrial sectors, such as aircraft construction, car body construction, commercial and special vehicles, agricultural machinery, defence, railway and mobile homes, to name a few.

Flexible today and tomorrow

The compact design of the DM 80 STATIC MIX fulfills all the technical and quality requirements of suppliers for aircraft construction and other industrial applications, where precise processing and dispensing of 2K materials, automation of manual processes as well as traceability of process sequences are crucial to the quality of component bonding.

Guaranteed quality

With the launch of the DM 80 STATIC MIX, we guarantee the quality you require.

The DM 80 STATIC MIX enables efficient material consump- tion and shorter production times, as well as higher quality, consistency and reliability in mixing and dosing. Additionally, it incorporates Industry 4.0 functionalities, a worldwide service network, and offers the possibility of integrating into your automation systems.

 

 

Simple processing and space-saving use

The DM 80 STATIC MIX is designed so that the operating personnel can fulfill the most diverse tasks easily and safely. Operation and visualization are carried out via a
15.6“ touchscreen.

A further feature is the process data logging, in which material pressures, pump torques, weighing data, correc- tion factors and alarm data are recorded and saved. In addition parameters for the discharge quantity, mixing ratio and the dosing time can be set. Particularly note- worthy is the interactive, menu-guided calibration and dosing process, which is permanently monitored and checked by a precision scale.

The dosing machine is mounted on a rollable chassis.

Spare mixing elements, separator for calibration, gloves and filling cups are within easy reach. The easy accessibility of the machine makes it quick and easy to carry out main- tenance and servicing work.

Mixing head with pressure monitoring
and flow-optimised material dosing

 

 

The servomotor-driven 2K precision mixing head MK 34 in stainless steel design and with integrated heating function is intended for pressure-monitored, static mixing of the material components for discharge rates from 1.0 to 2.5 g/s, although other discharge rates can also be configured. The mixing head has an optimized installation space which ensures flow-optimized material dosing.

The mixing ratio is infinitely variable from 10:1 to 1:1, but this depends on the pump size and material viscosity. Mixing is carried out by the ME 13/24 static mixer with low back pressure and high flow rate.

The automatic, pressure-controlled material feed to the mixing head is carried out by servo-driven precision eccentric screw pumps in sizes of 8.2 (A-comp.) and 1.8 (B-comp.) ccm/rev. For this purpose, pressure sensors are installed for process monitoring with reduced interference contours.
