Die casting machines are important equipment in the manufacturing industry for the production of various precision metal parts. In order to ensure the long-term stable operation of the machine and maintain efficient production, lubrication management is a link that cannot be ignored. A good lubrication system can not only reduce machine wear, extend the service life of the equipment, but also improve product quality and production efficiency. We will explore in depth how to optimize the performance of die casting machines by regularly checking and replenishing lubricants, and provide practical maintenance advice.

1、Importance of lubricating oil

Lubricating oil plays multiple roles in a die casting machine. First, it forms an oil film between the moving parts of the machine, reducing direct contact and thus reducing wear. Secondly, the lubricating oil helps to dissipate heat, transferring the heat generated by the movement to prevent the machine from overheating. In addition, the lubricant cleans the internal components and prevents the buildup of dirt and metal shavings, which can cause damage or failure of the components.

2、Check lubricating oil regularly

In order to ensure that the lubricant performs its role, regular inspection is key. Here are some check steps and suggestions:

Develop an inspection plan: According to the strength of the die casting machine and the manufacturer’s recommendation, develop a regular inspection plan. For example, check lightly used equipment once a week and high-load operating equipment once a day.

Check the oil level: Make sure the oil level is within the manufacturer’s recommended range. Too low an oil level may result in insufficient lubrication, while too high an oil level may result in bubbling or overflow.

Check oil quality: Lubricating oil should be kept clean and transparent. If the oil becomes cloudy or there are metal shavings, it may indicate that the internal parts are worn, and the lubricating oil needs to be replaced in time and the relevant parts need to be checked.

Check for leaks: Check the lubrication system regularly for signs of leaks. Any leaks should be repaired immediately to prevent inadequate lubrication and potential environmental contamination.

When the inspection finds that the lubricating oil is insufficient or the quality is decreased, it should be supplemented in time. The following are the steps and precautions for filling lubricating oil:

Choose the right oil: Use the lubricant recommended by the manufacturer to ensure that the oil meets the requirements of the machine. The wrong lubricating oil may damage the machine or reduce lubrication effectiveness.

Clean the oil filler: Before filling the oil, clean the oil filler to prevent dirt and impurities from entering the lubrication system.

Gradually add oil: Add oil slowly while observing the oil level to avoid excess. Excess lubricating oil may cause sealing problems or foaming.

Record maintenance activities: Record the date, time, type of oil and amount added for each inspection and refueling. This helps track maintenance history and identify potential problems in a timely manner.

4、Practical case

Assuming that a die casting shop has multiple die casting machines, by implementing a regular lubricant inspection and replenishment program, the shop management has seen a significant reduction in machine failure rates. In one quarter, they recorded machine operation data before and after the lubricant change, including the number of breakdowns and repair costs. According to the data, after the implementation of regular lubrication management, the failure rate is reduced by 30% and the maintenance cost is reduced by 25%.

5、conclusion

Lubrication management for die casting machines is a simple but extremely effective maintenance strategy that can significantly improve the reliability and productivity of your equipment. By regularly checking and replenishing lubricating oil, wear can be reduced, equipment life can be extended, and product quality can be maintained. Combined with accurate recording and analysis, maintenance schedules can be further optimized to achieve both cost savings and productivity gains.
