Ornamental plastic pepper balls, as decorative balls, are often used in ornaments, clothes, etc. Because of the large demand for decorative plastic pepper balls, there are many factories that produce such pepper balls, and the prices are not high. If the perforated pepper balls can not be manufactured by the process of middle holes in the mold injection, the prices of plastic balls are basically not competitive.

The small hole in the middle of the ornament pepper ball is realized by a thimble on the mold. The front mold of each plastic pepper ball will have a thimble that runs through the whole plastic pepper ball. When the front mold and the back mold of the plastic pepper ball are combined, the thimble will just be inserted into the thimble positioning hole of the back mold. When the injection molding is completed, the product will be separated from the mold, and the small hole in the middle of the plastic ball will be formed.
