EFFICIENT. MATERIAL-CONSERVING. DURABLE

With the CDF melt filter, MAS is setting new standards in the filtration of heavily contaminated plastics. The intelligent, fully process-controlled melt filtration automatically adjusts to the supplied material and reacts in real time to changing degrees of contamination.

The melt filter cleans even heavily contaminated plastics in the polyolefin range, operating continuously and filtering out even the smallest and most lubricating residues, such as dust, stones, and sheet contamination. Discover the efficient, material-saving, and long-lasting solution in melt filtration from MAS for yourself!

HOW ADAPTIVE MELT FILTRATION WORKS

The CDF melt filter from MAS adapts to individual conditions and reacts to the material supplied from the extruder and its degree of contamination. Unlike other filters, the CDF operates continuously and can be precisely controlled to the required process point. The melt pressure (which is kept constant as a result) increases the quality of the filtered material, ensures less waste, and—thanks to various screens and blades—impresses with low-maintenance durability.

All factors in the process of melt filtration can be adjusted at any time via the PLC, either manually or automatically with tracking control regulation. The filter discs, made of high-quality steel, offer a filtration fineness of 90 μm to 1,000 μm and a large active filter surface, ensuring high throughput even at particularly low specific values. The melt pressure also remains low, increasing the service life of the filter discs. Depending on the degree of contamination, the tear-off pressure on the blades is increased or decreased to maintain a constant melt pressure. Similarly, the screw discharge speed adjusts to the degree of contamination of the supplied material. This can also be adjusted via the PLC. There are also different screw geometries for different types and levels of contamination. The result: minimized melt loss and exceptional production efficiency.

Thanks to this adaptable, material-friendly performance, the melt filtration system can remove even heavy contaminants from polyolefins that would clog the filter holes in conventional melt filters. This results in a high quality of filtered material.
