L-HM68 Lifting Injection Molding Excavator

Updated: 2026-07-29

Overview

L-HM68 hydraulic oil is a specialized lubricant formulated for use in hydraulic systems of lifting and injection molding excavators. It is designed to meet the demanding requirements of high-pressure hydraulic systems, providing reliable performance under extreme conditions. This oil is part of the HM (Hydraulic Medium) series, which is known for its anti-wear additives and superior thermal stability. L-HM68 hydraulic oil is widely used in construction and industrial machinery due to its ability to reduce friction, prevent corrosion, and extend the lifespan of hydraulic components. Its formulation ensures smooth operation even under heavy loads and varying temperatures, making it a preferred choice for excavators and other heavy-duty equipment.

Physical and Chemical Properties

L-HM68 hydraulic oil exhibits a clear, amber-colored appearance and has a density ranging from 0.86 to 0.89 g/cm³ at 20°C. It is insoluble in water but mixes well with other mineral-based hydraulic oils. The oil's high viscosity index ensures consistent performance across a wide temperature range, from -20°C to 80°C. Key chemical properties include excellent thermal stability, which prevents breakdown under high temperatures, and oxidation resistance, which minimizes sludge formation. The oil also contains anti-wear additives that protect metal surfaces from wear and tear, ensuring long-term reliability of hydraulic systems.

Main Applications

L-HM68 hydraulic oil is primarily used in hydraulic systems of lifting and injection molding excavators, where it ensures smooth operation and minimizes wear on moving parts. It is also suitable for other construction machinery, such as loaders, bulldozers, and cranes, as well as industrial equipment requiring high-performance hydraulic fluids. In addition to excavators, L-HM68 is used in manufacturing plants for injection molding machines, where precise hydraulic control is critical. Its ability to maintain viscosity under pressure and temperature variations makes it ideal for applications demanding consistent performance and reliability.

Safety and Storage

When handling L-HM68 hydraulic oil, it is essential to follow safety precautions to avoid health risks. Avoid direct contact with skin and eyes, as prolonged exposure may cause irritation. Use protective gloves and goggles when handling the oil, and ensure adequate ventilation in storage and working areas. Store the oil in a cool, dry place away from direct sunlight and moisture. Keep containers tightly sealed to prevent contamination and evaporation. Dispose of used oil and empty containers according to local environmental regulations to minimize environmental impact.

B2B Procurement Guide

When procuring L-HM68 hydraulic oil, it is crucial to verify its compatibility with your equipment specifications. Check the manufacturer's recommendations to ensure the oil meets the required viscosity and performance standards. Purchase from reputable suppliers who provide certificates of analysis and quality assurance. Consider buying in bulk to reduce costs, but ensure proper storage conditions to maintain oil quality. Compare prices from multiple suppliers, but prioritize quality over cost savings. Establish long-term relationships with reliable suppliers to ensure consistent supply and technical support.
