Cleaning with the Comprex® process
Implementation
To illustrate this, 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 pipes – less pump capacity
- Reduced water consumption, up to 70%
- Mechanical cleaning without the addition of chemicals, thus reducing disposal costs
- Reduced system downtime, approx. 10% compared to conventional cleaning processes
- Stability and reproducibility in the cooling processes
- Fewer rejects
- Successful solution for compliance with legal regulations, e.g. CO 2 sustainability, energy management EN 50001
Cleaning with the Comprex® process
Summary
The cleaning of the two-part injection mold has shown that the loads on individual cooling channels can vary greatly, as evidenced by the deposits on the filter fleece and the measured pressure losses. This has fatal consequences for production operations; deposits and deposits have an insulating effect and reduce heat exchange, which leads to longer cooling times and thus cycle times in the system. This inevitably reduces production output. This also affects the quality of the manufactured products; deviations in the heat exchange are immediately reflected in the dimensional stability and the surface.
