Ten Recommendations For Fault Management And Prevention Of
Workshop Injection Molding Machines
Written By Jasmine HL
To do a good job in the management and prevention of injection molding machine failures, it is
necessary to grasp the causes of the injection molding machine failures, accumulate data and
data of frequent and typical failures, carry out failure analysis, attach importance to the study of
failure laws and failure mechanisms, and strengthen daily maintenance and inspection And
preparatory.
The fault management deployment process has the following aspects:
① Do a good job of propaganda and education, so that the operators and maintenance workers
consciously record, statistics, and analyze the failures of the injection molding machine, and put
forward reasonable suggestions.
② Closely combine the actual situation of injection production and the characteristics of
injection molding machine and divide the injection molding machines in use into A, B, and C
categories to determine the focus of fault management.
③ Use monitoring instruments to carry out planned monitoring on key parts of key injection
molding machines, and timely find signs of failure and deterioration information.
④ General injection molding machines also need to carry out daily inspections, roving
inspections, periodic inspections (including accuracy inspections), and intact condition
inspections through human senses and general inspection tools, focusing on mastering the
technical status of parts, mechanisms, and parts that are prone to failure. Information on
anomalies. At the same time, inspection standards should be formulated to determine the limits
of normal, abnormal, and faulty injection molding machines.
⑤ Carry out failure analysis and train maintenance personnel of injection molding machines to

master failure analysis methods.
⑥ Fault records are the basic data for fault management of injection molding machines and the
original basis for fault analysis and processing. The records must be complete and correct.
After the injection molding machine maintenance workers carry out inspections and fault repairs
at the site, they should carefully fill in according to the "Injection Molding Machine Fault Repair
Sheet", and the shop mechanics analyze and report to the injection molding machine
management supervisor monthly.
⑦ In addition to the daily maintenance of the breakdown situation of the injection molding
machine maintenance personnel in the workshop, the "failure repair list" and maintenance
records should be compiled monthly.
Through the statistics, sorting, and analysis of the fault data, calculate the fault frequency and
average fault interval of various injection molding machines, analyze the fault dynamics and
major fault causes of a single injection molding machine, and find out the fault occurrence rules
in order to highlight the key measures Countermeasures, feedback and analysis of failure
information to the planning department in order to arrange preventive repair or improvement
measures plan, can also be used as a basis for modifying the periodic inspection interval,
inspection content, and standards.
⑧ According to the statistically organized data, statistical analysis charts can be drawn. For
example, a single injection machine failure dynamic statistical analysis table is an effective
method for maintenance teams to visually manage faults and other problems. It is convenient for
management personnel and maintenance workers to grasp various types in time. In the case of
failure of the injection molding machine, it can also have a clear goal when determining the
maintenance countermeasures.
⑨ Through routine inspections of injection molding machine maintenance workers and injection
molding machine status inspections, the status information and failure symptoms obtained, as
well as relevant records and analysis data, the workshop injection molding machine maintenance
staff or the repair team leader, has problems with various types of injection molding machines.
Schedule routine maintenance in a timely manner;
Make full use of production gap time or holidays to prevent in advance to control and reduce
failures. For some failure symptoms and hidden dangers, the daily maintenance cannot afford,
then feedback to the planning department to arrange planned repairs.
⑩ Develop a flowchart of fault information management.
