Maintenance Tips for Injection Molding Machines During Ramadan
Hello, everyone! The Ramadan of 2025 is approaching. As we all know, Ramadan is a special period. During the day, employees fast, which can lead to a decrease in physical strength. Moreover, logistics may also be slower. These factors can potentially affect the normal operation of our injection molding machines. But don't worry! Today, we bring you a super practical maintenance guide for injection molding machines during Ramadan to help you ensure the efficient and stable operation of your machines. And here's some great news: Haijiang Injection Molding Machines are more energy-efficient! They offer lower operating costs and great value for money!
I. Core Maintenance Tips for Injection Molding Machines During Ramadan
1. Adjust Injection Molding Machine Maintenance Schedule
First, we need to avoid the high-temperature periods. During the day, employees fast and their physical strength is not as good as usual. If we still ask employees to work on maintenance under the scorching sun, it's too tough on them and the efficiency will be low. Therefore, key maintenance tasks should be scheduled in the early morning or evening when the temperature is lower and employees can work more comfortably.
If your factory is also working overtime at night to increase production, then we need to pay attention. The frequency of lubrication checks should be increased. Every two hours, check and record the oil pressure and temperature. This way, we can identify problems in time and prevent machine failures.
Another very important point is to prepare spare parts in advance. Logistics during Ramadan may be delayed. If we wait until the machine breaks down and then look for parts, it will be too late. So, for easily damaged parts like heating rings, hydraulic seals, and screw heads, we must purchase them in advance and keep them in the warehouse as a backup.
2. Focus on Key Maintenance Areas
The hydraulic system is a key area. We must check the oil temperature, which should be controlled below 55°C. When replacing the filter, don't forget to record the pressure difference. If you find that the oil is turbid, don't hesitate. Stop the machine immediately and change the oil.
The electrical system must not be neglected either. You can use an infrared thermal imager to check the terminal connections to see if there are any abnormal temperature rise points. If there are, mark them and deal with them in time. Also, the cooling vents of the servo motor should be cleaned every day. Don't let dust block them.
Mold fitting is also very important. The frequency of ejector pin lubrication should be increased. It is recommended to lubricate three times per shift. The water circuit of the mold temperature machine should be acid washed to remove scale every month. If you find that the flow rate has decreased by 15%, you must deal with it immediately. Don't let scale affect the temperature control of the mold.
II. Staged Maintenance Plan (Special Edition for Ramadan)

The mold locking mechanism needs to be checked. Measure the thickness of the lubricating grease film on the crosshead, which should be at least 0.1 mm. If there are scratches on the guide rail and the depth exceeds 0.5 mm, don't force it. Stop the machine immediately for repair.
The injection unit also needs attention. Record the fluctuation range of the screw retraction time. Under normal circumstances, it should be ±0.3 seconds. If you find any abnormalities, it may be due to wear of the check ring, and you should check it immediately.
And the emergency stop test, this is a matter of safety. When each shift is handed over, simulate the air cut-off and power cut-off to check the response time of the safety door, which must be controlled within 0.5 seconds to ensure the safety of workers.

The oil circuit is a special focus. Use a particle size detector to monitor the NAS grade of hydraulic oil, which should be controlled within grade 8. If it exceeds the standard, change the oil immediately.
The heating power also needs to be calibrated. Use a clamp meter to measure the current of each section of the heater. If the deviation exceeds 5%, the heating ring needs to be replaced.
The transmission system cannot be taken lightly either. The belt tension should be checked. The standard deflection is 10-15 mm, and if the gear clearance of the synchronous wheel exceeds 0.8 mm, it should be adjusted.

The servo system needs to be diagnosed. Through the HMI, retrieve the motor load curve. If the peak exceeds 120% of the rated value, the bearings may have problems and need to be checked.
The parallelism of the mold plate also needs to be checked. Use a laser alignment instrument to measure. If the deviation of the four corners exceeds 0.05 mm/m, the shims need to be adjusted to ensure the parallelism of the mold plate.
Energy consumption optimization is also very important. Calculate the electricity consumption per ton of product. If it increases by 5% compared to the benchmark value, check for mechanical resistance points to see if there are any areas for optimization.
III. Special Precautions for Production During Ramadan
Personnel Scheduling
Implement a dual-post mutual inspection system, with A and B roles for key positions. This way, we can avoid missed inspections due to fatigue. Everyone can help each other, ensuring safety and efficiency.
Environmental Control
The humidity in the workshop should be controlled between 40% and 60%. If the humidity is too high, place some desiccants in the control cabinet of the injection molding machine to prevent short circuits caused by dampness in the electrical circuits.
Emergency Plan
Keep an emergency power supply for two hours, such as an accumulator for pressure maintenance. In case of a power outage, the machine can still operate normally for a while. Also, compile a quick reference guide for common fault codes and place it in a conspicuous location in the workshop for everyone to quickly look up and deal with problems.
IV. Recommended Digital Management Tools
Predictive Maintenance System
Install vibration sensors, such as SKF @ptitude. This device can automatically warn of bearing failures up to two weeks in advance with an accuracy rate of 90%. Knowing in advance that the machine is about to fail allows us to prepare in advance and avoid production interruptions.
Electronic Inspection System
Use DingTalk Yida to build a maintenance process. Scan the code to check in and generate maintenance reports automatically. This way, we can clearly see what maintenance work has been done each time and whether there are any omissions.
Remote Assistance
Agree with the equipment manufacturer on a video technical support period during Ramadan, such as from 8 p.m. to 10 p.m. every day. If we encounter problems that cannot be solved, we can contact the manufacturer in time and get remote guidance through video to solve the problem quickly.
V. Cost Control Tips
Recycling Lubricating Oil
Use a three-stage filtration system (20μm→10μm→5μm) to recycle guide rail oil. This not only saves costs but also reduces the pollution of waste oil to the environment, killing two birds with one stone.
Mold Optimization
Complete the mold flow analysis before Ramadan and shorten the cooling time by 8%-12%. In this way, not only can we increase daily production capacity, but we can also reduce energy consumption and use it more energy-efficiently.
Off-Peak Electricity Use
Apply for time-of-use electricity rates and adjust low-power processes such as pressure maintenance to the off-peak period. This way, we can save a lot of electricity bills. In the long run, the cost advantage will be very obvious.
Summary: Haijiang Injection Molding Machines Are More Energy-Efficient and Offer Great Value
Everyone, through the above targeted measures, we can completely ensure that the overall equipment efficiency (OEE) of the injection molding machine during Ramadan is maintained above 85%, while reducing the unexpected failure rate by 40%. It is recommended to complete a comprehensive preventive maintenance two weeks before Ramadan and organize three emergency drills. This way, we can be fully prepared.
Finally, let me emphasize again that Haijiang Injection Molding Machines are not only reliable in quality but also more energy-efficient. They offer lower operating costs and great value for money. During the special period of Ramadan, choosing Haijiang Injection Molding Machines can not only ensure production efficiency but also reduce operating costs. It is definitely a wise choice for you!
