Stainless Steel Extruder Screen-Screen Packs-Filter Screens for Plastic and Polymer Melt

Extruder screens provide a clean and clear extrusion for the melt filtration and plastic extrusion processing machinery. Also called polymer filter screen or melt filter screen. Extruder Screen Mesh are mainly made from high quality SS 316, SS304L meshes ranging from 4 mesh to 500 mesh up to 5 microns, and used for Plastic and Rubber Industry. Edges styles cover spot welded edges and aluminum framing.

Major Types:
Disc / circular screen
Multilayer extruder screen packs
Single layer extruder screen
Mulity layer extruder screen
Rimmed screen
Screen filter belts
Cylindrical screens tubes

Layer: single layer or multilayer.

Material of filter screen/ filter mesh:  SUS304(AISI304), SUS316(AISI316), SUS316L(AISI316L), NO.201, NO.304, NO.316 stainless steel, also nickel alloy, Hastelloy alloy, Monel and Inconel.

Extruder Screen Application

This mesh screen filter is designed to filter out impurities from molten materials like plastics, polymers, rubber, and other compounds. Major application as following:

1, Plastic extrusion to produce clean films, pipes, and profiles;
2, Polymer production to remove unmelted particles;
3, Rubber extrusion;
4, Food and pharmaceutical industries;
5, Recycling plants for melted plastic scrap.

Screen Packs of Metal Materials and Guide for Choosing

Screen pack is extrusion filter screens of multiple layers stacked and welded into one piece used in extrusion processes to filter out impurities from molten materials. Screen packs are made from materials mainly plain steel, stainless steel and nickel alloys.

Stainless steel screen packs are much more resistant to rust than other materials. Screen packs from nickel alloy can be used in corrosive processing environment (such as from sulfuric acid, hydroflouric acid, and salt water). When choose screen packs, the working environment must be taken into consideration. Stainless Steel Extruder Screen Packs are widely applied on  PC, PP, PE, PS, HIPS, PET, PVC and other plastic sheet extruder, the membrane machine, granulator, and nonwoven fabrics, color masterbatch, filler, leather chemical fiber extruder, etc.

Benifits of ss extruder filter screen packs: High filtration finness/precision; High intensity; Easy to clean; Easy to replace; High temperature resistant; Corrosive resistant.

Multi-layer Wire Mesh Extruder Screen Set Spot Welded

Screen packs made from several layer wire meshes of different mesh sizes by welded together. The finest wire screen is in the center of the screen pack, the larger mesh opening wire screen is placed at outer sides for support and protection. The multi-layer extruder screens are arranged in a symmetrical fashion, which prevents the screen pack from accidentally being installed backwards. Multi-layer mesh screen packs are suitable for extrusion processing of plastics, polymers and fibers.

Process: Multi-layer wire mesh extruder screen sets are manufactured with different wire mesh pieces cut to desired shapes and sizes, then assembled properly and spot welded to form multilayer packs.

Welding Spots: Multi-layer mesh discs can be processed with different numbers and arrangement of welding spots according to your specific requirements.

We can produce multi-layer mesh discs with various combinations of materials: plain steel wire mesh and stainless steel wire mesh can be welded together, wire cloth of different specifications can be arranged to achieve ideal filtration.

Features:
Multi-layer extruder screen packs are extra strong, sturdy and convenient for problem free processing;
Can be assembled in proper sequence to eliminate operator error;
Multi layer screen pack can prevent foreign particles in the molten mass from going through the extrusion process;
This type of extruder screen is suitable for fine extrusion, clean and clear.

Multi-layer extruder screen packs common specifications:
Layers :2 , 3 ,4, 5 layers, or other more layers.
Material: Stainless steel(ss302, ss304, ss316, ss316L) woven wire cloth, copper wire cloth, galvanized wire mesh, aluminum alloy, and nickel alloys.
Shapes: Round, circle, disc, square, oval, rectangle, elliptical shape, other special shape
Packs Diameter 20mm - 900mm
Frame style: with or without frame, spot welded

Disc Type Wire Mesh Filter Screen - Circular Screen

Material of filter screen: SUS 301, 302, 304, 304L, 316, 316L stainless steel wire mesh, brass wire mesh, plain steel wire mesh galvanized wire mesh etc.
Diameter of wire mesh discs: from 2 to 30".

Features: Neat and precise filatration; High compressive strength; Heat-resistance and rust-resistance; Wear-resistance; Acid-resistance, alkali-resistcance; Economic cost; Easily installed and replaceable.

Application: Disc filter screen is widely used in filtering of gas and liquid, separating of other medium, fuel filter, vacuum filter,used in the field of petroleum, chemical industry, chemical fiber, rubber, metallurgy, medicine and food.
