In the field of precision casting, die casting machines are crucial production equipment, and their performance and lifespan largely depend on a well-designed lubrication system. Effective lubrication not only reduces energy consumption and wear but also ensures production stability and product quality. Let’s explore the lubrication methods used in die casting machines and their significant role in improving equipment efficiency and extending its lifespan.

1、Centralized Lubrication System:

A centralized lubrication system delivers lubricating oil to various lubrication points in the machine through a central pump. This system facilitates management and allows precise lubrication of multiple points at scheduled intervals, making it suitable for large-scale or multi-site die casting machine maintenance.

2、Decentralized Lubrication System:

In contrast to centralized lubrication, the decentralized lubrication system consists of independent oil tanks and pumps for each lubrication point. This approach offers more flexibility and allows personalized settings and maintenance based on the specific needs of different machine parts.

3、Manual Lubrication:

Manual lubrication is the most traditional method where operators use oil guns or oil cups to manually lubricate friction points at regular intervals. While simple, this method is time-consuming, labor-intensive, and prone to uneven lubrication or missed lubrication points.

4、Spray Lubrication:

Spray lubrication involves spraying oil mist onto lubrication points using compressed air or specialized spray pumps, forming a thin oil film. This method is suitable for high-speed rotating components or hard-to-reach areas.

5、Circulating Lubrication:

In the circulating lubrication system, lubricating oil circulates in a closed loop, passing through friction points before returning to the oil tank and being reused after filtration. This method reduces lubricating oil consumption while maintaining consistent lubrication effectiveness.

6、Solid Lubrication:

In certain special operating conditions, solid lubricants such as graphite or molybdenum materials are used in specific parts of die casting machines. They provide stable lubrication protection in high-temperature and high-pressure environments, especially in areas with frequent metal flow.

7、Oil-Air Mixture Lubrication:

Oil-air mixture lubrication combines the advantages of both oil and air by delivering a mixture of oil and air to achieve lubrication. This method effectively cools lubrication points and removes wear particles.

8、Automatic Lubrication:

Automatic lubrication systems utilize electronic control units to automatically control the timing and quantity of lubricating oil supply, ensuring precise and consistent lubrication while reducing lubrication issues caused by human factors.

9、Environmentally Friendly Lubrication:

With increasingly stringent environmental regulations, the demand for biodegradable lubricants and non-toxic lubricating oils is on the rise. These lubricants aim to minimize the impact on the environment and the health of operators.

10、Customized Lubrication Solutions:

For specific die casting applications, customized lubrication solutions may be necessary, including tailor-made lubricant formulations and specialized lubrication system designs to meet specific process requirements.


Choosing the appropriate lubrication method is crucial for ensuring the performance and improving the production efficiency of die casting machines. Different lubrication methods are suitable for various production conditions and equipment requirements, while proper lubrication management is key to ensuring the smooth operation of die casting machines. With technological advancements, new lubrication systems and materials continue to emerge, providing the die casting industry with more efficient and reliable choices.
