Wire mesh Filters are mainly used in plastic recycling machine and plastic extrusion machine in order to remove impurities/particles from molten polymers, which is crucial for ensuring the quality of recycled plastics. It’s widely used in the separation and filtration of petroleum, chemical, pharmaceuticals, food and other industries.
Screen mesh filter is constructed from full stainless steel wires, nickel wires, copper wires, brass wires, Monel wires, Hastelloy wires and other metal wires by using advanced weave technology. The mesh filter screen is a key part on the plastic recycling and plastic granules production. It can automatically replace the filter screen to ensure continuous production. Melt filter screens generally use single or multiple layers of filter mesh as filtration media. The filter mesh ensure the purity of the polymer melt through physical interception. Multi-layer filter screens (such as five-layer stainless steel mesh filter ) are sieved step by step through a gradually changing pore size (large pores on the outer layer → micro-pores on the inner layer), synchronously stabilizing the melt flow pressure (fluctuation <±0.5%), reducing broken strips or uneven weight.
Specification
Polymer extruder screen mesh filter is generally made of plain weave and Dutch weave wire mesh. The plain weave wire mesh features simple structure, economic to process and high cost-effectiveness and can meet the most filtration requirements of plastic products and rubber industries. In a filter, the Dutch weave wire mesh plays the role of fine filtration without requiring a backup filter screen, featuring high strength, high load capacity, simple structure and long service life.

Frequently Asked Questions (FAQ)
What are polymer screen mesh filters mainly used for?
They are primarily used in plastic recycling and plastic extrusion machines to remove impurities and particles from molten polymers, which is essential for ensuring the quality of recycled plastics. They are also used in chemical, petroleum, pharmaceutical, and food industries.
What materials are available for these extruder wire mesh filters?
The filters can be constructed from a wide range of materials, including stainless steel wires (SUS304/316L/904L), nickel wires, copper wires, brass wires, Monel wires, and Hastelloy wires.
How do multi-layer filter screens improve the extrusion process?
Multi-layer filters (like five-layer stainless steel mesh) sieve step by step using gradually changing pore sizes. This design stabilizes the melt flow pressure (fluctuations <±0.5%) and prevents issues like broken strips or uneven product weight.
What is the difference between plain weave and Dutch weave wire mesh?
Plain weave wire mesh offers a simple structure and cost-effectiveness for standard filtration. Dutch weave wire mesh provides fine filtration without needing a backup filter screen, offering higher strength, high load capacity, and a longer service life.
What shapes and temperature ranges can these filters support?
They are available in various shapes including round, oval, square, rectangle, and kidney shapes. They have a wide operating temperature range from -200℃ to 800℃.
