1、 Introduction

Aluminum die casting, as an important metal forming process, has a wide range of applications in many industrial fields. The selection and maintenance of aluminum die-casting equipment play an important role in ensuring production efficiency, product quality, and the service life of the equipment. Correctly selecting appropriate equipment and conducting scientific maintenance can bring stable production and good economic benefits to enterprises.

2、 Key points for selecting aluminum die-casting equipment

（1） Production demand assessment

Firstly, the specifications and performance of the equipment should be determined based on the production scale, product type, and quality requirements of the enterprise. For example, for enterprises engaged in large-scale production with high precision requirements, they should choose equipment with high automation, large clamping force, and precise and stable injection systems. For enterprises producing small castings or diverse product types, they may require equipment with more flexible parameter adjustment functions.

（2） Equipment quality and brand

Choosing well-known brands and reliable equipment is key. High quality equipment ensures better manufacturing processes, component quality, and overall performance, reducing equipment failures and maintenance costs. You can learn about the quality and brand reputation of equipment by consulting industry information, consulting peer companies, and conducting on-site inspections of equipment manufacturers.

（3） Technical parameter matching

Pay attention to the technical parameters of the equipment, such as mold clamping force, injection force, injection speed, and pouring volume, to ensure that these parameters match the size, weight, and complexity of the aluminum castings produced. For example, for thin-walled castings, a higher injection speed is required to ensure complete filling; For large castings, larger mold clamping force and pouring volume are required.

（4） Degree of automation

With the increase in labor costs and the demand for production efficiency, the degree of automation is also an important factor to consider when selecting. Automated equipment can achieve functions such as automatic pouring, picking up parts, and spraying release agents, which not only improves production efficiency but also reduces errors and safety risks caused by manual operations.

3、 Key maintenance points for aluminum die-casting equipment

（1） Daily cleaning

Regularly clean the equipment, including the body, mold, hydraulic system, cooling system, and other parts of the die-casting machine. Remove aluminum shavings, oil stains, dust, and other debris from the surface of the equipment to prevent them from entering the interior and affecting the normal operation of the equipment and the service life of its components.

（2） Lubrication and maintenance

Reasonable lubrication is the key to the normal operation of equipment. According to the requirements of the equipment manual, regularly lubricate various moving parts, such as the guide rails and sliders of the mold closing mechanism, and the piston rods of the injection mechanism. Choose the appropriate lubricant and pay attention to the amount and replacement cycle of the lubricant to ensure good lubrication of the equipment and reduce wear.

（3） Hydraulic system maintenance

Check the oil quantity, quality, and temperature of the hydraulic oil, and regularly replace the hydraulic oil and filter. Ensure the sealing of the hydraulic system to prevent oil leakage. At the same time, pay attention to checking the working status of hydraulic components such as hydraulic pumps, hydraulic cylinders, and hydraulic valves. If there are any abnormalities, repair or replace them in a timely manner.

（4） Cooling system management

The cooling system is crucial for controlling the temperature of equipment. Regularly check whether the cooling water pipeline is unobstructed and whether there is any leakage. Clean up impurities in the cooling water tank to ensure the quality of the cooling water. According to the production situation, adjust the cooling water volume and temperature reasonably to ensure that the equipment operates within the appropriate temperature range.

（5） Mold maintenance

Mold is the core component of aluminum die-casting production, and its maintenance directly affects product quality and mold life. After each use, the mold should be cleaned and rust proofed. Regularly check the wear of the mold, such as changes in the size of the core and cavity, and whether the movement of the slider and ejector pin is smooth. For severely worn parts, repair or replace them in a timely manner.

（6） Regular inspection and maintenance

Develop a regular inspection plan for equipment, including daily, weekly, monthly, and annual inspections. Conduct a comprehensive inspection of the mechanical structure, electrical system, hydraulic system, etc. of the equipment, promptly identify potential problems, and carry out repairs. At the same time, record the operation and maintenance history of the equipment to provide reference for subsequent maintenance and management.

4、 Conclusion

Choosing aluminum die-casting equipment correctly and doing a good job in maintenance is an important measure for enterprises to ensure smooth production, improve product quality, and reduce costs. When selecting, factors such as production demand, equipment quality, technical parameters, and automation level should be fully considered; During the maintenance process, attention should be paid to daily cleaning, lubrication maintenance, management of hydraulic and cooling systems, and maintenance of molds. Only in this way can aluminum die-casting equipment maintain good operating conditions and create greater value for the enterprise.
