There are several methods for manufacturing plastic hollow pepper balls. The most commonly used method is the plastic hollow pepper balls manufactured by blow molding, but the density of the hollow plastic pepper balls manufactured by blow molding is fixed, and the wall thickness of the plastic hollow pepper balls cannot be adjusted by the process. However, the plastic hollow pepper balls manufactured by welding process can manufacture hollow pepper balls with different wall thicknesses, that is, hollow plastic pepper balls with different densities, according to the requirements of customers.

The plastic hollow pepper ball is made by melting and bonding two plastic hollow pepper ball hemispheres at high temperature. The advantage of this process is that it has high strength, and it can be produced with many kinds of plastic materials, and the wall thickness of the plastic hollow pepper ball can be adjusted according to customers' requirements, so that the density of the plastic hollow pepper ball can be controlled well.
