Melt filters, laser filters and screen discs for extrusion and recycling plants – Precise filtration for maximum plastic quality
Melt filters, laser filters and screen discs – essential filter elements in plastics processing
Melt filters, laser filters, and screen discs are central components in modern extrusion, compounding, and plastics recycling plants. They ensure that impurities are reliably removed from the plastic melt and contribute significantly to consistently high product quality, trouble-free production processes, and a long service life for the systems.
Whether in the production of virgin material or the reprocessing of plastic recyclates – high-quality filter systems ensure a clean plastic melt and protect downstream machine components from damage. MSV GmbH supplies high-quality melt filters, laser filters and screen discs for numerous machine manufacturers and a wide range of applications in the plastics industry.
What are melt filters?
Melt filters are used directly in the melt stream of extrusion and recycling plants. As the molten plastic mass flows through the filter, foreign substances such as metal particles, paper, wood, rubber, glass fibres or other impurities are reliably retained. This ensures that only purified plastic melt enters the subsequent production process.
Efficient melt filtration improves the quality of the end product, reduces rejects and protects extruders, dies and other machine components from premature wear.
What are laser filters?
Laser filters are particularly precisely manufactured filter elements whose filter openings are produced using state-of-the-art laser technology. Compared to conventional filter plates or wire meshes, they are characterized by exact hole geometry, a large open filter area and uniform material flow.
Due to their precise manufacturing, laser filters enable reliable removal of the finest impurities with simultaneously low pressure loss. They are particularly suitable for demanding applications in plastic recycling, compounding and high-quality extrusion processes.
What are screen discs?
Screen discs are circular filter discs made of high-quality wire mesh or sintered metal materials that are used in melt filter systems. They filter out the smallest impurities from the plastic melt and are available in various diameters, mesh sizes and material qualities.
Depending on the application, screen discs are used individually or as multi-layer filter packages to achieve optimal filtration performance and a long service life. They are an economical and proven solution for numerous extrusion and recycling processes.
What are the functions of melt filters, laser filters and screen discs?
All three filter elements fulfill a central task within plastics processing: they clean the plastic melt and ensure consistently high quality of the end product.
Their most important functions include:
- Filtration of impurities from the plastic melt
- Protection of extruders, dies and tools
- Improvement of the surface quality of plastic products
- Reduction of rejects and material losses
- Ensuring a constant material flow
- Increase in process reliability
- Extension of the service life of downstream system components
- Optimisation of the economic efficiency of the production process
Applications in the plastics industry
Melt filters, laser filters and screen discs are used in numerous areas of plastics processing and plastics recycling. These include:
- Plastics recycling
- Extrusion lines
- Compounding lines
- Granulation lines
- Film extrusion
- Pipe and profile extrusion
- Masterbatch production
- Processing of technical plastics
- Reprocessing of recyclates
They are suitable for plastics such as polyethylene (PE), polypropylene (PP), PET, PVC, polyamide (PA), ABS, polystyrene (PS) as well as numerous other thermoplastics and compounds.
