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

Impact-resistant plastic shell pepper balls are manufactured by mold hot-pressing technology. The plastic shell pepper balls manufactured by this technology can be made from a variety of plastic raw materials, and the density of plastic shell pepper balls and the thickness of plastic shell can also be adjusted according to requirements. The plastic shell pepper balls are manufactured by mold pressing technology. Generally speaking, the manufacturing cost will be higher than that produced by blow molding process, Because the process is much more complex than the blow molding process, and the efficiency is also lower than the blow molding process, the impact strength and compressive strength of the plastic shell pepper ball are generally improved by increasing the wall thickness of the plastic shell pepper ball.
