When plastic pepper ball manufacturers manufacture plastic pepper balls, firstly, the phenomenon that the plastic pepper ball blank ball shrinks cannot occur in the injection molding process, because the plastic pepper ball is small in size, and the blank ball is slightly shrunk, which is difficult for eyes to see. If the blank ball enters the ball grinder for grinding, the precision of the plastic pepper ball cannot be rounded, resulting in the small size of the plastic pepper ball and affecting the precision of the plastic pepper ball.

Therefore, the temperature of the mold must be high when the plastic pepper ball is injected, so that the blank ball will not shrink when the plastic pepper ball is injected. When the plastic pepper ball manufacturer grinds the plastic pepper ball with a ball grinder, it is easy to make a mistake that the upper grinding plate of the ball grinder adds too much pressure. The disadvantage of too much pressure is that the plastic pepper ball will be deformed during the pressing process, and the grinding process will be carried out under the deformed condition. It is easy to cause the precision of plastic small pepper balls to be out of tolerance, which will affect the precision and roundness of plastic small pepper balls. Therefore, when processing plastic small pepper balls, you should not put too much pressure on the ball grinder, and only when the pressure is normal can you process qualified plastic small ball products.
