1. Mold Heating: Before installing the preform mold, it needs to be heated to improve plastic flow and reduce the probability of mold damage.
2. Mold Cleaning: Before use, the mold surface must be thoroughly cleaned to ensure that no dust or other impurities remain inside, which could affect the quality of the preform.
3. Mold Maintenance: After use, necessary maintenance is required, such as timely replacement of worn parts and regular lubrication. This will effectively extend the mold's lifespan.
