An injection molding machine is a modern, highly efficient piece of machinery equipment that demands significant investment, operates on a large scale, consumes substantial resources, and delivers high output. Due to the machine’s fully automated operation and exceptionally high efficiency, its components experience considerable wear and tear. Under such demanding working conditions, even the failure of a single part can lead to a complete shutdown of the entire machine, disrupting production and severely reducing overall efficiency. That’s why regular maintenance and upkeep of injection molding machines are essential for ensuring smooth, uninterrupted production.

I. Contents of Injection Molding Machine Maintenance

Although injection molding machines are easy to operate, their high level of automation means they come equipped with highly specialized mechanical, hydraulic, electrical components—and dedicated auxiliary systems—requiring precise operational coordination. As a result, routine maintenance tasks for these machines cover a wide range of areas.

Daily maintenance for injection molding machines primarily includes the following tasks: checking each component for wear, ensuring lubricants are properly applied, and verifying the cleanliness and integrity of oil-lubricated parts or mechanisms; inspecting ventilation in the IQT unit and electrical control boxes; confirming that wiring and voltage levels are functioning correctly; assessing the cooling system’s performance and checking for any blockages in the material feed tubes; examining the mold assembly to ensure all components are operating smoothly; verifying that screws and connections are securely tightened; monitoring whether hydraulic and nitrogen pressures—as well as other pressure settings—are within normal ranges; and checking the cleanliness of the drive discs, among other things.

II. Standardizing and Institutionalizing Daily Maintenance for Injection Molding Machines

The maintenance of injection molding machines should be thoroughly planned on a daily, quarterly, and annual basis. Each stage should clearly outline the specific items that require inspection and servicing, organized into a checklist and systematically recorded for easy reference and to ensure nothing is overlooked in the future.

Establishing a comprehensive troubleshooting system is also essential. Each time workers complete a fault repair, they should document the details and compile monthly summaries into "Repair Record Forms." These forms will serve as a foundation for future fault statistics, organization, and analysis, enabling teams to better understand the root causes and frequency of issues, strengthen troubleshooting efforts, and ultimately boost overall production efficiency.

In social production, every piece of production equipment requires regular maintenance and upkeep, as prolonged, high-intensity operation inevitably leads to wear and tear. To prevent accidents and boost productivity, routine maintenance is absolutely essential.
