Equipment Used to Increase Process and Dosing Accuracy
Additional equipment options can be ordered for the DM 50x dosing machine series which further increase the process and dosing accuracy. The use of patented technology for high-pressure water rinsing of the mixing chamber results in a number of advantages in quality and economy. The use of tap water in high-pressure water rinsing, which in most cases may simply be discharged into a standard wastewater system after use, saves costs in contrast to the disposal of solvents that results from conventional solvent-based cleaning.
The pneumatic AIR-CLEAN nozzle cleaning system ensures that the mixing head dosing nozzle is always clean. The intervals of this cleaning function are freely adjustable in the control system of the mixing and dosing systems.
The NOZZLE-CONTROL nozzle measuring unit uses two laser sensors positioned at right angles to check the presence and the exact positioning of the mixing head nozzle, as well as whether material is adhering to the nozzle. If the nozzle lies outside the tolerances, a signal tone accompanied by an error message is emitted. In such cases, the operator checks the dosing nozzle and cleans it if necessary.
By means of the WEIGHT-CONTROL dosing system with a calibrated electronic scale, the constant discharge quantity of the mixing head dosing process is compared to the target value in the dosing program. The repeatedly accurate application rate is an important criterion for dosing accuracy.
The component identification sensor mounted on the mixing head detects the presence of the component and transmits the information to the control system. The combination of high process and dosing accuracy, a constant travel speed of the mixing head, and precise control of the repeatedly accurate start and end of the dosing process ensures high seal quality.
