The hydraulic system is the backbone of industrial, construction, and agricultural machines. Its high-power density and efficiency execution make it the preferred choice for high-energy applications. This manuscript presents the evidence against the statement, Whenever the system runs to its full capacity, hydraulic oil heats up more as compared to partial loads.“ Our experimental study on Injection Molding Machine (IMM) hydraulic system tries to reshape the above statement by presenting the fact where we came across that lower system loading case is causing higher hydraulic oil temperatures than full loading.” The concern started when the machine at lower speeds results in frequent shutdowns due to increasing operating temperature high alarm!“ This article presents the study to resolve the stated issue completely. For the design evolution, a systematic diagnostic approach is displayed based on the six-sigma and the associated mathematical model. Our study concludes with an approach to find the self-balancing system for the case where the temperature increase is must be due to the higher rate of heat addition than the rate of heat rejection. Presented learning can be equally extended for the other fields of interest, as care should be taken to understand the passive system losses, which can result in elevated temperatures due to lower cooling capabilities.

液压系统是工业，建筑和农业机械的基础。其高功率密度和高效率执行使其成为高能量应用的首选。该手稿提供了反对该陈述的证据，“每当系统满负荷运行时，与部分负荷相比，液压油就会发热更多。”我们对注射成型机（IMM）液压系统的实验研究试图通过提出上述陈述来重塑上述陈述。我们遇到的情况是，系统负载较低，导致液压油温度高于满负荷。” 当机器在较低速度下由于工作温度升高而导致频繁停机时，就开始担心了！”本文提出了一项研究，以彻底解决上述问题。为了设计演变，基于六西格码和相关的数学模型，系统地显示了一种诊断方法。我们的研究以一种找到自平衡系统的方法作为结论，该方法用于温度升高必须归因于热量添加速率高于散热速率的情况。可以将学习的范围同样地扩展到其他感兴趣的领域，因为应注意了解无源系统的损耗，该损耗可能由于较低的冷却能力而导致温度升高。
