How to extend the service life of the mold

1. Regularly clean the oil

Friends who have processed wood pellets know that after the end of production every day, oil must be used to replace wood chips left in the die hole. Here I would like to remind everyone that if the mold is not used for more than a month, it is recommended to take out the oil in the mold. Therefore, the oil will gradually harden during long-term storage, which will make it difficult to remove when it is used next time, which will seriously affect the follow-up of the mold. use.

2. It is not necessary to clean the mold for a long time

If the mold and pressure roller will not be used for a long time, it is recommended to remove the mold and clean it before storing. It mainly cleans the particles inside the mold and the sawdust attached to the surface of the mold. In this way, on the one hand, it prevents the hardening of the particles due to long-term storage and is difficult to remove. On the other hand, due to the water absorption of the sawdust, if the sawdust on the surface is not removed, the corrosion of the mold surface may be accelerated.

3. The mold should be stored in a dry and ventilated place

Most of the molds of the wood pellet machine are made of alloy steel. If they are kept in a humid place for a long time, the surface of the mold may be damaged due to air corrosion, which will greatly reduce its service life.

4. the handling process should be careful

The mold of the sawdust pellet machine is a high-precision accessory. The mold holes are carefully processed according to the compression ratio of the mold. If the structure of the inner wall of the mold hole is damaged during the handling process, it may cause molding during the processing of the pellets. low rate and short service life.

5. Filling with oil

After the daily particle processing, it is necessary to use oil to grind for a period of time to ensure that all the oil is left in the die hole, which is of great benefit to the work of the next day and is also conducive to the long-term use of the mold. The oil can be made by mixing waste engine oil and sawdust, which can be made once and recycled.
