POM plastic hollow pepper ball has the characteristics of high precision, good surface finish and oil resistance. However, due to the high density of POM plastic, the only way to reduce the density of POM plastic hollow pepper ball is to make the wall thickness of the plastic hollow pepper ball thin. However, POM material is brittle and easy to break.

The manufacturing process of POM plastic hollow pepper ball is made by laser welding. The advantages of laser welding plastic hollow pepper ball are high precision and high strength, but the disadvantages are low manufacturing efficiency and high cost of equipment and tools. Therefore, the price of laser welding plastic hollow pepper ball products is higher than that of ordinary blow molding process.
