Best Practices for Effective Cooling Channel Cleaning
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:
Consequences of Neglecting Cooling Channel Cleaning
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 […]
Types of sediments and scale deposits
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 […]
A few words about parallel connections…
We see this type of connections most often in bigger 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 […]
Do you control the performance of your injection molds?
The purpose of the efficient cooling system of the mold is to guarantee an even distribution of temperatures on individual molding cavities, which translates into appropriate dimensional tolerances and the quality of injected parts. Any temperature deviations caused by flow disturbances and / or the inability of the channels to effectively take away the heat […]
Factors influencing the decrease in cooling efficiency
Every year, companies around the world unknowingly lose hundreds of thousands of Euros due to the gradual decline in cooling efficiency in their tools and machines. Lower mold efficiency, longer cycle time due necessity of counteracting dimensional deviations of plastic parts, longer mold downtimes, maintenance and servicing – all these factors increase operating costs and […]
The most expensive machine is the one you don’t use, because it will never pay off. Don’t buy a pig in a poke.
When talking to customers, we always try to convince them to test the device they are interested in. We believe that before making an investment decision, the effectiveness of the solution should always be verified, especially when we are not dealing with a product that directly boosts a company’s productivity (like an additional injection molding […]
