Restoring Long-Dormant Injection Molding Machines: A Comprehensive Guide
The downtime of an injection molding machine can be a significant setback for manufacturers. However, with the right steps and procedures, you can effectively restore the machine and get it back to production seamlessly. This guide will provide you with essential tips and best practices to ensure you address any issues efficiently.
Seeking Manufacturer Support
If the manufacturer offers after-sales service, it is advisable to leverage their expertise. Their experienced technicians can guide you through the troubleshooting process and ensure that the machine is restored to optimal working condition. If the manufacturer is no longer available, consider consulting other reputable injection molding machine manufacturers for assistance. They are likely to offer the necessary guidance and support.
Basic Precautions and Safety Measures
1. Before commencing any repairs or mold cleaning procedures that last longer than 10 minutes, it is essential to move the injection seat back and disengage the nozzle from the mold. Ensure the motor is turned off in this process. Maintenance personnel must not be left unattended.
2. It is strictly forbidden to start the machine or motor while dealing with it or the mold. Always ensure the power supply is cut off whenever the body needs to enter the machine tool or the mold is being opened.
3. Take care not to hit the mold with the injection seat when it is open to prevent accidental mold detachment.
Operational Best Practices
1. Generally, avoid injecting the material for more than 5 seconds each time. If the machine fails to move for two consecutive times, inform a nearby colleague to stay alert for potential safety hazards.
2. When cleaning rubber heads at the nozzle, avoid handling with bare hands. Use iron forceps or other tools to prevent burns or other injuries.
3. The injection molding process involves high temperatures, high pressures, and high power, making it imperative to avoid walking, climbing, or placing any objects on the glue tube. This action can lead to accidents such as scalding, electric shocks, and fire hazards.
Prevention and Safety Checks
1. In the event of an empty hopper, avoid using metal bars, rods, or any rough poking tools to probe the hopper. Such actions can lead to damage to the split screens, screen covers, and magnetic frames within the hopper. Additionally, the presence of metal objects in the barrel can cause serious damage and accidents.
2. If any abnormal sounds, peculiar odors, sparks, oil leakage, or other unusual conditions are detected during operation, immediately halt the machine and report to relevant personnel. Explain the observed fault and provide possible causes to facilitate quicker resolution.
Conclusion
By adhering to these guidelines and maintaining a safe working environment, you can successfully restore a long-dormant injection molding machine and ensure its operation is smooth and efficient. Leveraging the resources and expertise of your manufacturer or consulting with other professionals can provide additional support and guidance to keep your production processes running smoothly.
