Screenchanger (Melt Filter) for plastic extrusion

Screen changers (Melt Filters) filter contaminants such as foreign particles (metal, wood, black spots, etc.) and unwanted particles such as unmolten material from the melt. The subsequent components, such as melt pumps, coextrusion adapters, and flat dies, are protected from damage due to metal particles; thus, the quality of the melt and, consequently, the end product is improved and kept constant.

By regularly changing the screen, the screen changer ensures continuously high purity and quality of the material. Intelligently controlled screen changers improve the efficiency of the extrusion process by allowing screen changes without interrupting a constant flow.
