The following are detailed maintenance steps:

1. Daily maintenance includes cleaning the mold, screw and machine head to prevent plastic residue accumulation from affecting production. Check the lubrication system to ensure that moving parts such as guides and chains are well lubricated. Monitor the air pressure and hydraulic system, keep the pressure stable and replace the hydraulic oil regularly. In addition, key components such as electric eyes and sensors need to be checked to avoid dust interference.

2. Regular deep maintenance involves more comprehensive inspections, such as disassembling the mold to clean the mold cavity and vent holes, checking the wear of the screw and barrel, and calibrating the temperature and pressure control system. Replace the hydraulic oil, check the seals, and adjust the parallelism of the mold every quarter or every year to prevent product defects. Through system maintenance, the failure rate can be reduced, the life of the blow molding machine can be extended, and the production efficiency and product quality can be ensured to be stable.

3. Standardized use of operators is also an important part of maintaining plastic blowing machine. Operators should be trained regularly to ensure that they are familiar with equipment parameter settings, correct mold loading methods, and abnormal situation handling procedures. Avoid overload operation during production, pay attention to abnormal phenomena such as equipment vibration and noise, and stop the machine in time for inspection.

4. At the same time, recommended to establish complete plastic blow molding machine file to record the time, content and replaced parts of each maintenance, so as to analyze the fault pattern and optimize the maintenance plan. Only by combining standardized operation with scientific maintenance can the performance of the blow molding machine be maximized and the maintenance cost be reduced.
