1. The surface of the mold is uneven: if the surface of the mold is uneven, the polished surface of the trademark will be easily worn during mechanical polishing, resulting in poor polishing effect.
2. Inappropriate polishing materials: Different parameters such as hardness, particle size and density of the polishing materials will affect the quality of the polished surface of the trademark. If the hardness of the polishing material used is too high or too low, or the particle size is not suitable, it will lead to problems in the polished surface of the trademark.
3. insufficient or too long polishing time: the polished surface of the trademark cannot be completely polished and smooth due to insufficient polishing time. If the polishing time is too long, the polished surface of the trademark will be excessively polished, resulting in a decrease in surface gloss.
4. Inappropriate polishing machine parameters: The polishing machine parameters, such as rotational speed and pressure, also have an important influence on the quality of the polished surface of the trademark. If the parameter setting is unreasonable, the polished surface of the trademark is prone to problems.
