POM plastic pepper ball has high hardness and good surface smoothness, but its toughness is not as good as PA plastic pepper ball and PP plastic pepper ball. Moreover, if the cooling rate of injection molded plastic pepper ball is too fast, the surface of POM plastic pepper ball will produce fine cracks due to shrinkage, which will affect the quality of POM plastic pepper ball.

When POM plastic pepper balls are processed by injection molding, the mold temperature should be kept below 15℃ and the temperature of the injection molding machine should not exceed 205℃, so that the plastic pepper balls produced under such parameters will not crack due to rapid cooling. When POM plastic pepper balls are processed, the pressure of the ball grinder cannot be adjusted too much, and the plastic pepper balls will be ground in the state of pressure deformation, so it is difficult to have high precision. The above two points are POM plastic pepper balls processing.
