In this article, we will explore the maintenance practices that can help extend the life of the injection unit and ensure consistent performance.
Injection Unit of die casting maintenance–Regular Inspection
Regular inspection of the injection unit is the first step in maintenance. This should include checking for any signs of wear, leaks, or damage to the components. Look for cracks in the cylinder, wear on the plunger, and any misalignment of the injection mechanism. These issues can affect the accuracy and consistency of the injection process, leading to defects in the final product.

Lubrication
Lubrication is key to the smooth operation of the injection unit. All moving parts, such as the plunger and the injection cylinder, should be regularly lubricated with the appropriate type of lubricant. This reduces friction and wear, preventing premature failure of the components. Be sure to follow the manufacturer’s recommendations for lubrication intervals and types of lubricants to use.

Injection Unit of die casting maintenance–Cleaning
Keep the injection unit clean to prevent the buildup of metal residues and other contaminants. After each production run, clean the unit to remove any leftover metal or debris. You can do this using a combination of brushing, wiping, and, if necessary, a cleaning solvent. Ensure that all cleaning materials are compatible with the materials of the injection unit to avoid damage.
Calibration
Calibration of the injection unit is necessary to ensure that it operates within the specified parameters. This includes checking the injection speed, pressure, and volume settings. Any deviations from the set parameters can lead to inconsistent casting quality. Regular calibration helps to maintain the precision of the injection process and ensures that the machine produces parts that meet the required specifications.
Training
Proper training of the machine operators is crucial for the maintenance of the injection unit. Operators should be familiar with the machine’s operation, maintenance procedures, and safety protocols. They should be able to identify potential issues early and take appropriate corrective actions. Regular training sessions can help to keep the operators’ skills up to date and ensure that the machine is operated and maintained correctly.
