1. Carefully check the working status of each control unit during operation to prevent abnormalities in the auxiliary system. Maintenance of the heating and control system is especially important for hot runner molds. At the end of each production cycle, the mother-in-law measuring rod heater, band heater and thermocouple should be used and compared with the technical description of the ABS injection mold to ensure that the function is intact. At the same time, the control loop can be tested with an ammeter installed in the loop. The oil in the hydraulic cylinder used for core pulling is discharged as much as possible, and the nozzle is sealed to prevent the hydraulic oil from leaking or contaminating the surrounding environment during storage and transportation.
2. If you hear any abnormal sounds or other abnormal conditions during the production process, you should stop the inspection immediately. The mold maintenance personnel should inspect the molds in the normal operation of the workshop. When an abnormality is found, it should be handled in time.

Third, when the operator is at the handover level, in addition to delivering the production, the process is critical to the critical record and the use of the mold must be specified.
4. When the mold completes the production quantity of the product, when it is necessary to replace other molds, the mold cavity should be coated with anti-rust agent, and the accessories of the mold should be sent to the ABS injection mold maintenance personnel. The final mold can be used to produce qualified products. These pieces are sent together to the maintenance staff. In addition, you should also send a mold use list, fill in the machine using the mold, the number of products produced in a month of the year, and whether the mold is now good. If there is a problem with the mold, it is necessary to fill in the mold on the board, propose specific requirements for modification and improvement, and submit the unprocessed sample to the custodian and leave it in the mold for repair.
5. A mold library should be established, a special person should be established, and a mold file should be established. If possible, computer management of the mold should be performed. The mold library should be selected for low humidity and ventilation. The temperature should be kept below 70%. If the humidity exceeds 70%, the mold is easily rusted. ABS injection molds should be stored on the shelf, paying attention to corrosion and dust. Mark signs that require repair or repair.
