Many factory maintenance teams only lubricate ball screws when abnormal noise appears. This passive maintenance method is the main reason for precision attenuation and shortened service life. Unlike ordinary automation equipment, injection molding ball screws face high temperature, dust pollution, and frequent impact loads, requiring fixed-cycle professional maintenance systems.
1. Why Injection Machine Screws Need Strict Fixed-Cycle Maintenance
-
High-temperature radiation causes grease carbonization and failure
-
High-frequency impact leads to loose preload and structural fatigue
2. Standard Maintenance Cycle (Factory Universal Standard)
-
Check for abnormal noise and vibration during operation
-
Confirm no dust accumulation and oil leakage
-
Clean surface floating dust with air gun
-
Check the tightness of sealing parts
-
Clean residual carbonized old grease inside the nut
2.4 Quarterly Precision Calibration (Every 3 Months)
-
Re-calibrate preload and eliminate minor backlash
3. Critical Maintenance Rules That Cannot Be Violated
-
Never use ordinary butter: Only dedicated high-temperature and high-load grease is allowed
-
Avoid long-term full-load standby: Continuous static pressure causes metal fatigue
After maintenance, the screw should achieve smooth operation, uniform oil film, no abnormal noise, no jitter during reversing, and stable repeated positioning accuracy. If hot-state drift still exists, it indicates incomplete cleaning or insufficient lubrication.

4. How to Judge Whether Maintenance Is Qualified
Conclusion: Precision and service life rely 50% on product quality and 50% on standardized maintenance. Strictly following the injection molding ball screw maintenance cycle can maintain long-term stable yield and avoid unnecessary replacement costs.
