Professional Guide for Selecting Lubricants for Die Casting Machines

In the manufacturing industry, die casting machines are essential equipment for casting precision parts. Just as the ancient saying goes, “To do a good job, one must first sharpen one’s tools.” Selecting the right lubricant is crucial for ensuring the efficient operation and extended lifespan of die casting machines. Lubricants play multiple roles in die casting machines, such as reducing wear, dissipating heat, and preventing corrosion. Let’s discuss how to choose the right lubricant for die casting machines.

When selecting lubricants for die casting machines, several key factors need to be considered:

1、Temperature resistance: During the die casting process, the machine generates high temperatures. Therefore, the lubricant must have excellent high-temperature stability. It should maintain its viscosity and lubricating properties at high temperatures to prevent oil degradation and failure.

2、Anti-wear protection: Die casting machines endure high pressures and wear during operation. Lubricants need to have excellent extreme pressure performance to form a strong lubricating film under high pressure and high-speed friction conditions. This film reduces direct contact between mechanical components and minimizes wear.

3、Oxidation stability: Lubricants constantly come into contact with air during use, making them susceptible to oxidation. Choosing lubricants with good oxidation stability can resist oxidation and prolong the oil change interval.

4、Compatibility: Lubricants should be compatible with other materials used in die casting machines, such as seals and plastics, to prevent corrosion or other adverse reactions. Additionally, lubricants should not react with the casting materials and affect the quality of the castings.

5、Environmental friendliness: With increasingly stringent environmental regulations, selecting environmentally friendly lubricants has become more important. Environmentally friendly lubricants are not only harmless to human health but also reduce environmental pollution.

6、Safety performance: In certain situations, lubricants may come into contact with hot metals, so they need to have good fire resistance to minimize the risk of fire.

In practical applications, the selection of lubricants also needs to be based on the specific model of the die casting machine and the recommendations provided in the user manual. Different die casting machines may have different lubricant requirements. Therefore, when choosing lubricants, it is important to carefully read the manufacturer’s suggestions.

Furthermore, the use and maintenance of lubricants are also crucial.

Regularly inspecting the condition of lubricants and promptly replacing aged or contaminated lubricants can effectively prevent mechanical failures and ensure production stability. Additionally, proper lubrication management can reduce energy consumption and improve energy efficiency.

In conclusion

selecting the appropriate lubricant for die casting machines is a comprehensive decision-making process that considers multiple factors. Through scientific analysis and rational selection, we can ensure that die casting machines operate in their optimal condition, bringing greater economic benefits to enterprises.
