For the newly-purchased mold, it should be well protected from being damaged or scraped by materials. When it refers to the changes or dismantlement of mold, you should be careful and not damage the surface. What’s more, you should lubricate the surface of newly changed mold with oil.
For installing the mold, you should not make it deviated. If not doing so, you will confront the consequences like serious wear of mold, strong vibration of wood pellet machine and low output of biomass pellets. Besides, you should not use the steel hammer to dismantle the mold. Or else, the mold would be much easier to be damaged.
Screws for fastening the mold should be suitable in length. If they are too long or too short, mold will be damaged. For these screws, they should be qualified in torque and clean without dust inside. For the marks of mold, they should not be stamped or polished. Besides, new ring die should work with new mold. It is not allowed to use the new ring die and old mold together.
