On days May 20-23, 2025 welcome to booth A14, hall 4 during the fair PLASTPOL in Kielce. For the first time, we will present our new CoolingCare machine feature: automatic unclogging of completely clogged cooling channels - without dismantling the mold.

This is the result of more than 8 years of development of cavitation cleaning technology. The new feature is based on an extensive automated algorithm and sequence of operations using the phenomenon of hydraulic hammer and cavitation, effectively breaking through obstructions from hard deposits and corrosion products.

What do you gain?

No need to disassemble the mold
Lower operating costs
Save time and eliminate downtime

See for yourself - booth A14, hall 4. See you in Kielce!

To minimize the risks associated with declining cooling efficiency, regular cleaning of cooling channels must be incorporated into routine mold maintenance. Here are some best practices to help keep cooling channels clean and operational:

1. 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.
2. 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.
3. 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.
4. 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.

To minimize the risks associated with declining cooling performance, it is essential to include regular cooling duct cleaning in your mold service routine. Here are some best practices to help keep cooling channels clean and efficient:

1. Regular preventive cleaning: Set a cleaning schedule based on the frequency of mold use and the type of coolant circulating in the system. Regular diagnostics and short preventive cleaning sessions are effective in preventing the buildup of contaminants before they cause more serious problems that reflect on the process.
2. Flow monitoring: Implementing systems to monitor the flow of the cooling medium through the ducts allows early detection of decreases in flow or increases in delta T (the difference in inlet and outlet temperatures), which can indicate blockage or scale/rust buildup.
3. Documenting maintenance activities: Keep detailed records of all maintenance activities, including cleaning dates/times and recorded flow expenditures for individual channels. These records help track the decline in cooling performance over time and can guide future decisions on tool maintenance activities.
4. Selecting the right tool: Make sure the device dedicated to cleaning has features that will allow you to clean effectively and efficiently as well as monitor the performance of individual tool cooling circuits. It's a good idea if the device also has a function to save the data with the ability to play it back and refer to it in subsequent cleaning sessions.

Neglecting regular cleaning of cooling channels can have serious consequences for both the mold and the production process. As contaminants accumulate, the flow of water becomes restricted, reducing the efficiency of the cooling system. Lower heat dissipation due to a layer of low thermal conductivity insulation, combined with restricted flow, can cause localized overheating in the mold (known as hot spots). This leads to uneven cooling and unstable part quality. As a result, the percentage of defective parts increases, production costs rise, and more frequent mold repairs or even replacements become necessary. In critical cases, the cooling channels may become completely clogged, forcing a mold shutdown, disassembly, and mechanical drilling of the blockage, which generates enormous costs. This not only increases operational expenses but also negatively affects the ability to meet production deadlines. In times when customer quality requirements are so demanding, maintaining stable part quality with the shortest possible cycle time is crucial.

Potential Problems Arising from Tool Thermal Disturbances:

1. Extended Cycle Times: Contaminated cooling channels result in slower heat transfer, meaning the mold requires more time to cool. This leads to longer production cycles, reducing overall process efficiency and increasing operational costs.
2. Part Defects: Uneven cooling can affect part quality. Defects such as warping, sink marks, and dimensional deviations become more common, leading to a higher rejection rate by quality control. Additionally, uneven cooling can create internal stresses, reducing the strength of the product and causing it to crack under load.
3. Faster Mold Wear: Reduced cooling efficiency forces the mold to operate at higher temperatures for longer periods, accelerating the wear of mold components. This can shorten the tool's lifespan and require more frequent repairs and refurbishments.
4. Higher Energy Consumption: An inefficient cooling system requires more energy to maintain the mold's proper temperature, leading to increased energy costs and a greater environmental impact.

Neglecting to regularly clean cooling channels can have serious consequences for both the mold and the production process. As contaminants accumulate, water flow is reduced, which lowers the cooling system's capacity. Lower heat removal capacity as a result of a layer of insulation with low thermal conductivity, combined with throttled flow, can cause localized overheating in the mold (known as hot spots), leading to uneven cooling and unstable part quality. As a result, the percentage of defective parts increases, production costs rise, and more frequent mold repairs or even mold replacement becomes necessary. In critical cases, cooling channels can become completely clogged, forcing mold downtime, the need to dismantle the mold and mechanically reaming out the blockage, which generates huge costs. This not only increases operating costs, but also negatively affects the ability to meet production deadlines. At a time when customers' quality requirements are so exorbitant, maintaining stable molding quality with the shortest possible cycle time is crucial.

Potential problems arising from tool thermal disturbances:

1. Extended cycle times: Clogged cooling channels result in slower heat transfer, which means the mold takes longer to cool. This leads to longer production cycles, reducing overall process efficiency and increasing operating costs.
2. Disadvantages of molding: Uneven cooling can affect part quality. Defects such as deformations, sink marks and dimensional deviations become more common, leading to more rejections by the quality control department. In addition, the uneven cooling process of the workpiece can lead to stresses, reduced product strength and cracking under load.
3. Faster mold wear: Low cooling efficiency forces the mold to operate at higher temperatures for longer periods, accelerating wear on mold components. This can shorten tool life and require more frequent repairs and reconditioning.
4. Higher energy consumption: An inefficient cooling system requires more energy to maintain the proper mold temperature, leading to increased energy costs and greater environmental impact.

The mineral deposits are primarily composed of calcium and magnesium carbonates. Carbonates, which are generally insoluble, are precipitated by heating water containing soluble calcium and magnesium bicarbonates. Bicarbonate is thermally unstable and will decompose to form carbonates and thus limescale when heated.

Factors influencing scale deposition:

- The higher the (temporary) water hardness, the more scale will form.

- The higher the pH (alkaline pH) of the water, the greater the tendency to scale

- The higher the temperature to which the water is heated, the more scale build-up will be present.

Precipitation and scaling on channel walls increases dramatically when the water temperature exceeds 60 degrees Celsius. It also depends on the hardness of water, so in some areas the problems caused by limescale are greater than in others. To counteract limescale problems, most injection molders deploy some form of water treatment to minimize the risk of mineral-based deposits such as calcium or magnesium.

The DS2 cleaner is recommended to remove limescale from calcium and magnesium deposits.

Another type of deposit is formed during the corrosion process. These can be solid, water-insoluble deposits (such as incrustations during the microbial corrosion process) or scale - a layer of solid corrosion products or hard iron oxides. Like other deposits, they are dangerous to the ducts, restrict the flow and reduce the efficiency of heat removal.

Rust-based scale in the channels of water-cooled molds will typically have a high concentration of iron oxides / corrosion by-products. This is mainly because companies use "closed-loop" water systems where the concentration of iron oxide is up to seven times higher than in regular tap water. Another reason for the formation of deposits from the corrosion process may be the water left in the channels after the cleaning process. The dissolved oxygen in the water reacts with steel causing corrosion.

The DS1 cleaner is recommended for descaling with a high concentration of iron oxides.

Mineral deposits originally consist of calcium and magnesium carbonates. Carbonates, which are generally insoluble, are precipitated by heating water containing soluble calcium and magnesium bicarbonates. Bicarbonates are thermally unstable and break down to form carbonates and thus scale when heated.

Factors affecting scale deposition:

• The higher the (temporary) hardness of the water, the more scale will precipitate.
• The higher the pH (alkaline pH) of the water, the greater the tendency to scaling
• The higher the temperature to which the water is heated, the more scale will precipitate.

Scale precipitation and deposition on sewer walls increases dramatically when water temperatures exceed 60 degrees Celsius. It also depends on the hardness of the water, so in some areas the problems caused by scale are greater than others. To counter scale problems, most injection molding plants use some form of water treatment to minimize the risk of deposits based on minerals such as calcium or magnesium.w

For descaling of calcium and magnesium deposits, it is advisable to use DS2 cleaner.

Like other deposits, they are dangerous to the ducts, restricting flow and reducing the efficiency of heat extraction.

Scale in water-cooled mold ducts will usually have a high concentration of iron oxides/corrosion by-products. This is mainly because companies use "closed loop" water supply systems where the concentration of iron oxide is up to seven times higher than in ordinary tap water. Another reason for the formation of deposits as a result of the corrosion process may be water left in the sewers after the cleaning process. Oxygen dissolved in the water reacts with the steel, causing corrosion.

To remove scale with a high concentration of iron oxides, it is advisable to use DS1 cleaner.

We see this type of connections most often in larger molds that have a large number of cooling channels. It is impractical to connect cooling to each of the channels separately, so they are usually bundled into one manifold, the purpose of which is to supply the cooling media to the individual cooling circuits in the mold. Of course, this type of solution is not perfect. We must remember that the parallel connection of channels will typically generate various pressure drops (these drops may result from large disproportions in diameters, lengths or distances of the channels from each other, forcing them to be connected to the manifold with hoses of different length) which inevitably translate into uneven distribution of the cooling liquid to individual circuits, even if a manifold with an appropriate pressure-balancing volume is used. This solution should be treated as a compromise, as we should always try to connect channels in such a way that the risk of uneven distribution of the coolant is as low as possible. In a situation where one of the circuits is partially or completely blocked, a parallel connection will prevent the cleaning liquid from reaching this channel, because the solution will always try to find the path of least flow resistance.

However, it should be remembered that the process of cleaning the channels is not a process of cooling. This is a common misconception that people who bridge channels for cleaning use, arguing that the mold is connected in the same way during production. If we want to effectively clean the circuits connected to each other by means of a manifold, we must use a feed pump with a much higher capacity, that is able to overcome pressure drops generated by the cooling system, while maintaining the appropriate dynamics, which will guarantee the effectiveness of cleaning in the shortest possible time. The effectiveness of devices equipped with single pumps with a higher flow rate depends primarily on the number of liters of pumped liquid in a given time, which is never the most effective solution. That is why it is worth looking for solutions using hybrid systems, such as the patented, two-stage hydromechanical cleaning process in CoolingCare machines, in which two cooperating pumps for each of the cleaning sections are used. This approach gives much more flexibility and significantly reduces cleaning time.
