What Is a Screen Changer?
A screen changer is a critical device in plastic molding and recycling, designed to filter out foreign particles from molten resin. This process safeguards the quality of the final product by ensuring that only pure resin passes through to the molding or recycling stages.
The device operates by passing the molten resin through a series of screens, which can be adjusted for size and shape to capture unwanted particles. A driving mechanism rotates these screens, while a discharge device removes the accumulated foreign particles.
Essential to maintaining high standards in product quality, screen changers consist of a cylindrical screen, a mechanism for rotation, and a system for particle discharge. Their ability to efficiently remove impurities from molten resin not only improves the quality of the output but also increases production efficiency.
