PP hollow plastic pepper balls are mostly made by blow molding technology. The advantages of blow molding technology are simple mold, low manufacturing cost and low precision. The wall thickness of PP hollow plastic pepper balls is limited and uneven, resulting in insufficient strength of PP hollow plastic pepper balls.

In the manufacturing of PP plastic hollow pepper ball by blow molding process, to solve the problem of accuracy, it is necessary to process high-quality hollow plastic pepper ball mold. Generally, the price of blow-molded plastic pepper ball mold with good quality is more than tens of thousands of yuan, while that of blow-molded plastic pepper ball mold with poor quality is only several thousand yuan, so the quality of mold directly affects the accuracy of blow-molded plastic hollow pepper ball. The best way to solve the precision of plastic hollow pepper balls is to blow mold with good quality plastic hollow pepper balls.
