Polymer Filtration Market

The plastics and polymer industry requires many different filters to insure a clean melt stream. Our metal polymer filtration screens are engineered to fit all styles and types of melt pumps and screen changers. The end goal of our product is to insure the final quality of your product.

The most common screen changers for melt filtration use single or multilayer wire cloth extruder screens. We produce these in round discs, rectangular or kidney shaped screens. The construction of the screen pack is critical to process performance and final product quality. Mesh combinations are carefully chosen to achieve a high strength pack that provides desired filtration levels and optimal throughput. To assist in the production of sensitive or high value polymers we offer frame pack screens for superior sealing and control.

Many screen changers (for example… virgin resin or film production) use cylindrical wire cloth filters of different complexities. For the separation and removal of small particles or gels from the melt stream, we produce cylindrical filter elements of sintered wire cloth or pleated metal fiber felt from 1-75 micron.

For plastics recycling we produce inexpensive food grade stainless steel and carbon steel filters for the extrusion process. Strong wire cloth belts with special weave patterns and edge treatments are commonly used in continuous screen changers.
