POM plastic hollow pepper ball has high precision and smooth surface, excellent oil resistance, self-lubricating performance, and POM hollow pepper ball can not be manufactured by blow molding process, but only by die hot pressing technology.

To make POM plastic hollow pepper balls, firstly, two semi-circular hollow pepper balls should be made, then the semi-circular hollow pepper balls should be put into a special fixture, and then the edges of the two hollow pepper balls in the mold should be heated at a temperature of about 180 degrees for about 10 minutes, and then the molds should be pressed together. After the POM plastic hollow pepper balls in the mold are cooled and molded, the molded POM plastic hollow pepper balls should be taken out, and after the air is removed, the POM plastic hollow pepper balls should be put into a grinding ball.
