Para minimizar los riesgos asociados a la disminución de la eficacia de la refrigeración, la limpieza periódica de los canales de refrigeración debe incorporarse al mantenimiento rutinario de los moldes. Estas son algunas de las mejores prácticas para mantener los canales de refrigeración limpios y operativos:
- Regular Preventive Cleaning: Establish a cleaning schedule based on the mold’s usage frequency and the type of coolant circulating in the system. Regular diagnostics and short preventive cleaning sessions effectively prevent contaminant buildup before it leads to more significant issues that impact the process.
- Flow Monitoring: Implement systems to monitor the flow of the cooling medium through the channels. Early detection of flow reductions or increases in the delta T (the temperature difference between inlet and outlet) can indicate blockages or the accumulation of scale or rust.
- Documenting Maintenance Activities: Maintain detailed records of all maintenance activities, including cleaning dates/times and flow rates recorded for individual channels. This documentation helps track cooling efficiency declines over time and can guide future decisions regarding tool maintenance.
- Choosing the Right Tool: Ensure that the cleaning device has features that allow for efficient and thorough cleaning, as well as monitoring the performance of each cooling circuit in the tool. It’s beneficial if the device also has data logging capabilities, enabling you to review and reference the data in future cleaning sessions.
