PPA plastic hollow pepper ball, also known as high-temperature resistant plastic hollow pepper ball, has a thermal deformation temperature of over 300 degrees and a long-term use temperature of over 170 degrees. PPA plastic hollow pepper ball has high hardness, good surface finish and excellent oil resistance, and is widely used in automobile field, mechanical equipment and other industries.

PPA plastic hollow pepper balls are mainly produced by laser welding technology. The semi-finished products after welding need to be ground by a special ball grinder for plastic pepper balls, and then polished to obtain the finished PPA plastic hollow pepper balls.
