Reduce plastic injection molding machine failure some preventive measures

To do a good job of injection molding machine fault management and prevention, we must master the reasons for the occurrence of injection molding machine faults, accumulate information and data of frequent faults and typical faults, carry out fault analysis, pay attention to the study of fault laws and fault mechanisms, and strengthen daily maintenance, inspection, and pre-repair. The unfolding procedure of fault management has the following 8 aspects.

1. Do a good job of propaganda and education, so that the operation workers and maintenance workers consciously record, count, and analyze the injection molding machine failures carefully and put forward rationalization suggestions.

2. Closely combine the actual injection production and the characteristics of the condition of injection molding machines, and divide the in-use injection molding machines into three categories, A, B, and C, in order to determine the focus of fault management.

3. Adopt monitoring instruments to monitor the key parts of key injection molding machines in a planned manner, so as to discover the signs of failure and information of deterioration in time.

The general injection molding machine should also be inspected by human senses and general inspection tools, such as daily point inspection, tour inspection, periodic inspection (including accuracy inspection), and intactness inspection, etc., so as to grasp information on the technical status and abnormalities of parts, mechanisms, and components that are prone to failures. At the same time, inspection standards should be formulated to determine the boundaries of normal, abnormal, and fault of the injection molding machine.

4. Carry out fault analysis and train injection molding machine maintenance workers to master fault analysis methods.

5. Fault record is the basic information to achieve the fault management of injection molding machine and is the original basis for fault analysis and processing, the record must be complete and correct. After the inspection and fault repair, the injection molding machine maintenance workers should fill in the content of the "injection molding machine fault repair sheet" carefully, and the workshop mechanic should analyze and submit the monthly statistics to the supervisor of injection molding machine management.

6. In addition to mastering the daily fault situation, the workshop injection molding machine maintenance worker should gather the "fault repair order" and maintenance records on a monthly basis. Through the statistics, collation, and analysis of the breakdown data, the breakdown frequency and average breakdown interval of each type of injection molding machine can be calculated, the breakdown dynamics of a single injection molding machine and the causes of key breakdowns can be analyzed to find out the occurrence pattern of breakdowns so that countermeasures can be taken by highlighting the key points, and the breakdown information can be fed back to the planning department for arranging preventive repair or improvement measures, and can also be used as the basis for modifying the regular inspection interval, inspection content, and standards. It can also be used as the basis for revising the interval of periodic inspection, inspection content, and standards.

According to the statistical information, statistical analysis charts can be drawn, such as the single injection molding machine fault dynamic statistical analysis table is an effective way for the maintenance team to visually manage the faults and others, which not only facilitates the management and maintenance workers to grasp the situation of faults occurring in each type of injection molding machine in time, but also provides a clear target in determining the maintenance countermeasures.

7. Through the daily inspection tour of injection molding machine maintenance workers and the status inspection of the injection molding machine, the status information and fault signs obtained, as well as the relevant records and analysis data, the workshop injection molding machine maintenance personnel or repair team leader for each type of injection molding machine problems, timely arrangement of daily maintenance, making full use of production gap time or holidays, to achieve prevention in advance, in order to control and reduce the occurrence of faults. For certain signs of failure, hidden problems, daily maintenance can not afford, then feedback to the planning department to arrange the planned repair.
