Synthetic Ester-Based Hydraulic Fluids: The Smart Choice for Efficiency and Sustainability

Hydraulic systems are integral to plastic injection and blow moulding machines, providing the necessary force to mould materials into desired shapes and control over movements such as clamping, injection, and ejection. A crucial component for these systems to ensure precision, efficiency, and longevity in production processes, is hydraulic fluid.

The choice of hydraulic fluid directly impacts the machine's performance and reliability, as well as heavily influencing operational factors such as maintenance frequency, repairs, energy usage, and fluid consumption.​

Traditionally, mineral oil-based hydraulic fluids have been the go-to choice for many systems, providing adequate lubrication for general applications. However, the high-temperature, high-output demands of plastic moulding is a harsher environment. By their nature, mineral oil-based fluids are increasingly susceptible to oxidation, sludge formation, and varnishing.

On the other hand, saturated synthetic ester-based fluids, like Mi240 HYDRAULIC, offer a modern alternative. These fluids are engineered to provide superior performance, boasting excellent oxidation resistance, biodegradability, and a higher viscosity index. This means they maintain optimal performance across a wider temperature range, reducing the risk of thermal degradation and extending the fluid's service life.​

Mi240 HYDRAULIC stands out in the realm of hydraulic fluids by offering a range of advantages that address common operational challenges while promoting environmental sustainability:

Enhanced Oxidation Resistance

One of the primary issues with conventional mineral oil-based fluids is their tendency to oxidise, leading to the formation of varnish and sludge, which severely compromises system performance. Mi240 HYDRAULIC exhibits exceptional resistance to oxidation and varnish, effectively minimising these problems and ensuring improved system operation over an extended period.

Biodegradability

As environmental considerations become increasingly important in industrial applications, Mi240 HYDRAULIC offers a sustainable solution. Classified as "readily biodegradable," it provides a more environmentally friendly alternative to traditional mineral oils, reducing environmental impact without compromising performance.

Improved Operational Efficiency

Field trials have shown that hydraulic systems using Mi240 HYDRAULIC operate with greater efficiency, achieving energy savings of approximately 8%. This enhanced efficiency not only lowers operational costs but also contributes to reducing the overall carbon footprint, aligning with sustainability goals.

Extended Service Intervals and Reduced Maintenance

Due to its superior stability and resistance to degradation, Mi240 HYDRAULIC requires fewer fluid changes compared to conventional fluids. This extended service life reduces maintenance downtime and associated costs, enhancing overall operational productivity.

Seamless Compatibility and Easy Transition

Switching to Mi240 HYDRAULIC is a straightforward process that requires minimal effort. A simple flushing procedure to remove existing fluids is all that’s needed before refilling with Mi240. This ease of transition makes it a cost-effective and hassle-free upgrade for operators looking to improve system performance and sustainability.

Plastic injection and blow moulding present environmental challenges due to energy consumption, reliance on fossil fuels, and plastic waste generation. Therefore, the optimum choice of hydraulic fluid is essential, as it plays a pivotal role in determining machine performance, operational efficiency, and environmental impact. While mineral oil-based fluids have served the industry for many years, advancements in fluid technology offer manufacturers an opportunity to enhance their operations. With benefits like improved oxidation resistance, biodegradability, energy efficiency, and extended service intervals, Mi240 HYDRAULIC presents a compelling case for those looking to optimise their hydraulic systems.

“Early adopters of Mi240 HYDRAULIC have experienced numerous benefits to date. One plastics manufacturer has been using Mi240 HYDRAULIC fluid in their machinery since February 2021 and laboratory reports indicate that the product has arrested the wear particles previously generated. Additionally, no signs of oxidation have been reported.”
