Injection Molding Machine Is “Feverish”? 90% Ignore These 5 Cooling Water Facts!
Is your injection molding machineFrequent oil leaks, rapid rise in oil temperature, blockage in the cooling channel of the feed inlet.The problem may lie in cooling water management! According to Arburg officials, 90% of equipment failures are related to cooling water. The following five points can help you save huge repair costs!
The water temperature must be "just right," with cooling water ideally at 25°C! If it's too high, cooling fails; if too low, condensation occurs, leading to water accumulation in the electrical box causing short circuits and emulsification of hydraulic oil, resulting in internal damage to the machine.

2️⃣ The optimal water pressure difference is ≥1.5 bar.
The pressure difference between inlet and outlet water is too small, the oil temperature soars above 55°C, seals aging accelerates, and hydraulic components wear doubles!
3️⃣ Water quality = Equipment lifespan
Mud impurities can clog the cooler and damage the seals. It is recommended to install a filter, regularly clean the water tank, and soften the water quality. Don’t let "dirty water" ruin your valuable equipment!
The Impact of Impure Water on Cooling Water Control Valves
4️⃣ Don't overlook key areas
In addition to hydraulic oil, it is also necessary to cool the feeding port, servo motor, and frequency converter.
The feeding port will form clumps if overheated and accumulate water if too cold, affecting production continuity.

Prevention is better than repair.
Regularly check water temperature, water pressure, and water quality, and clean the cooler; it saves more money than emergency repairs! Arburg recommends checking once a month and performing a deep maintenance once a year.
Cooling water management is the core of preventive maintenance! Do these five things well.Equipment lifespan extended by 30%, failure rate reduced by 50%.
