Tool cleaning
Cleaning of 2 different tools at KraussMaffei
Reference project KraussMaffei Technical Centre
Task
- Cleaning the cooling circuits of older molds before startup
- Individual sewer cleaning to document flow and debris.
System structure
MCU-20 + decompression box:
Here designed as a mobile unit with integrated water tank, feed pump. In the return flow is the screen deck to accommodate filter fleeces (Fig.1)
Technical data
- To clean: Large tool (Fig. 2) | Small tool (Fig. 3)
- Type and quantity of deposits unknown
- Cleaning equipment
- MCU-20 (the optimized successor model is ToolClean, control panel with pressure and dosing unit)
- Decompression box (successor model is ConnectBox) for wastewater-saving cleaning with recirculation
- Filter fleece: retains solids and prevents backflow of discharged particles into the system
Cleaning with the comprex® process
Implementation
For illustration purposes, the cooling channels were cleaned individually and the discharge was documented in each case with a new filter fleece. Fig. 4 shows the respective discharge in the fliter fleece for 6 separate cooling circuits.
Advantages for the operator
- Energy saving, free lines-less pump capacity
- Reduced water consumption, up to 70%
- Mechanical cleaning without the addition of chemicals, thus reduced disposal costs
- Reduced plant downtime, approx. 10% compared to conventional cleaning processes
- Stability and reproducibility in the cooling processes
- Less scrap
- Successful solution to meet legal requirements, e.g. sustainability CO2, energy management EN 50001

Cleaning with the comprex® process
Summary
The cleaning of the two-part injection mold showed that the loads on individual cooling channels can vary greatly, as indicated by the deposits on the filter fleeces and the measured pressure losses. This has fatal consequences for production operations. Coatings and deposits have an insulating effect and reduce the heat exchange, which leads to longer cooling times and thus cycle times in the plant. Inevitably, this reduces production output. Also associated with this is the quality of the manufactured products, deviations in heat exchange are immediately reflected in the dimensional stability and surface.
