Because the plastic hollow pepper ball is a hollow structure, it sometimes needs to bear certain pressure and impact. The traditional manufacturing method of plastic hollow pepper ball is blow molding. The biggest disadvantage of plastic hollow pepper ball manufactured by blow molding is that its wall thickness is too thin to bear too much pressure and impact.

Impact-resistant hollow plastic pepper balls are made by hot-pressing molding technology. The hollow plastic pepper balls made by this technology can be made of various plastic raw materials, and the density and thickness of the hollow plastic pepper balls can also be adjusted according to requirements. The hollow plastic pepper balls are made by compression molding technology, and generally, the manufacturing cost will be higher than that of blow molding technology, because the technology is much more complicated and the efficiency is lower than that of blow molding technology. Generally, the hollow plastic pepper balls are improved by increasing the wall thickness of the hollow plastic pepper balls.
