Hydraulic oil properties in die casting machines ensure smooth operation with proper viscosity and anti-wear additives for longevity.

Hydraulic oil is a critical component in die casting machines, ensuring smooth operation and efficient performance. It serves multiple functions, including lubrication, heat transfer, and power transmission. This article will explore the key properties of hydraulic oil and their significance in die casting operations.
Hydraulic oil properties in die casting machines

1. Viscosity
Viscosity is a measure of a fluid’s resistance to flow. In die casting machines, hydraulic oil must have the appropriate viscosity to ensure efficient lubrication and power transmission. High – viscosity oils provide better lubrication but may increase energy consumption, while low – viscosity oils offer easier flow but may not provide sufficient lubrication. HAICHEN recommends using hydraulic oils with a viscosity grade suitable for the specific operating conditions of the machine.
2. Thermal Stability
Thermal stability is crucial for hydraulic oil in die casting machines, which operate at high temperatures. The oil must be able to withstand these temperatures without breaking down or forming sludge. Thermal degradation can lead to increased viscosity, reduced lubrication, and potential damage to the machine.
3. Oxidation Resistance
Oxidation resistance is another important property of hydraulic oil. It can cause the oil to thicken and form deposits, leading to reduced efficiency and potential machine failure. Hydraulic oils with good oxidation resistance help maintain the oil’s properties over time, reducing the need for frequent oil changes and maintenance.
4. Water Resistance
Water contamination can be a significant issue in hydraulic systems, leading to corrosion and reduced oil performance. Hydraulic oils with good water resistance help prevent these issues by repelling water and maintaining their properties even in the presence of moisture. HAICHEN’s machines are designed to work with hydraulic oils that have excellent water resistance, ensuring reliable performance in various operating conditions.
5. Compatibility with Machine Components
The hydraulic oil must be compatible with all components of the die casting machine, including seals, hoses, and pumps. Incompatibility can lead to leaks, wear, and damage to these components. HAICHEN ensures that its machines are compatible with a wide range of hydraulic oils, providing detailed recommendations to ensure optimal performance and longevity.
