1. Plasticizing system
The gearbox needs to change oil regularly. Choose 150 (or 220) medium extreme pressure industrial gear oil. Change the oil after 500 hours of use for the new machine, and then change the oil every 3000 hours. When the machine just stops working and the gearbox is still at a high temperature, change the oil. After the old oil is drained, use a small amount of new oil to clean the sediment, clean the lubricating oil pump filter, and then add new oil to 1/2~2/3 of the liquid level window.

2. Maintenance of special hydraulic system for wall thickness control
Regular oil change: The hydraulic system usually recommends using 46# anti-wear hydraulic oil. After 500 hours of use of the new machine, it is recommended to change the oil for the first time, and then change the oil every 3000 hours. Clean all filters (suction filters) while changing the oil. , High pressure filter, oil return filter, servo valve seat filter) and oil tank, the oil volume is 1/2~2/3 of the level gauge.

3. hydraulic system
Regular oil change: The hydraulic system usually recommends using 46# anti-wear hydraulic oil. After 500 hours of use of the new machine, it is recommended to change the oil for the first time, and then change the oil every year (the oil quality is different, and the oil change interval may be different) , Clean the filter and oil tank while changing the oil, the oil volume is 1/2~2/3 of the level gauge

4.add extreme pressure grease regularly
The mold-moving and mold-opening and closing mechanisms are frequent and fast, so they are equipped with automatic or manual lubrication devices, but the lubricating device should be regularly checked and filled with grease. This can increase and extend the service life of the machine, and bring you better economic benefits. Refueling the slide block of the moving mold rail separately, once a week; other parts once every shift.

5. Waterway
The downtime is long. When the temperature is low, the mold waterway, machine cooler, barrel cooling, die head cooling water and other waterway cooling parts should be cooled. The cooling water should be cleaned up to prevent long-term structure or freeze cracking.
