Precautions For Use And Maintenance Of Graphite Molds

Precautions for use
Before use in a high temperature environment, preheating should be carried out and heating should be carried out gradually to avoid thermal shock and cracks caused by sudden temperature changes. During transportation and installation, be careful to avoid mechanical damage caused by impact and falling, and prevent damage to the mold surface.
The mold surface should be kept clean before and after use to avoid dust, impurities and oxides from adhering, which may affect the performance and molding effect of the mold.
Use appropriate lubricants when necessary to reduce friction and wear, but avoid using lubricants that will chemically react with graphite.
Strictly control the use temperature of the mold to avoid exceeding the temperature resistance range of the graphite material to prevent thermal deformation and performance degradation of the material.
Heat and cool evenly to avoid local overheating or uneven cooling, which may cause thermal stress concentration in the mold, causing cracks or deformation.
Maintenance recommendations
1. Regularly check the various parts of the mold, especially those that are prone to wear and damage, such as the mold core and mold inserts, and replace damaged parts in time.
2. The mold should be cleaned in time after use to remove residual processing materials and impurities to prevent accumulation and keep the mold surface smooth.
3. After using in a high temperature environment, the mold should be kept away from the air for a long time to prevent oxidation. A protective atmosphere or anti-oxidation coating can be used.
4. When not in use, the mold should be stored in a dry and ventilated environment to avoid moisture and corrosive gas erosion.
5. Regularly carry out professional repairs and maintenance, such as surface polishing and repair, to extend the service life of the mold and ensure molding quality.
6. Establish detailed usage records, record the temperature, time, processing materials and maintenance of each use, which will help to find problems in time and take preventive measures.
