PA plastic pepper ball increases the strength of PA plastic pepper ball by adding glass fiber into the material. Although it can improve the strength and impact resistance of PA plastic pepper ball, the appearance and accuracy of PA plastic pepper ball with glass fiber are better than those without raw materials.

After adding glass fiber to PA plastic, the physical properties of the material have changed, and the glass fiber in the plastic is combined with PA plastic in a physical state. When the plastic PA pepper ball processed by this material is ground in the later stage, because of the existence of glass fiber in the material, the hardness of glass fiber and PA material after grinding is different, and the surface of the ground plastic PA ball is frosted, and the precision will be greatly affected in the rough state. Moreover, the polishing effect of glass fiber PA plastic pepper ball can not reach the production of pure PA material.
