Screen Changer

Removing melt impurities is a critical step before the pelletizing process. The screen changer filters out contaminants in the melt, ensuring material purity, stabilizing production, and improving product quality.
Rongpai has independently developed a series of piston screen changers designed for seamless integration with underwater pelletizing systems.
