Plastic Extruder Screens
Extruder screens provide a clean and clear extrusion for the melt filtration and plastic extrusion processing machinery. This pack screen filter is designed to keep away mixing of foreign particles in finally equipped extrusion product. Also called polymer filter or melt filter screen. Extruder Screen Mesh packs 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. Their edges styles cover spot welded edges and aluminum framing around the spot-welded edges.
According to shape, Extruder Screens can be divided into
- Disc Extruder Screens: Round/circular extruder screens, square/rectangle, toroidal/annulus, kidney shape extruder screens;
- Cylindrical Extruder Screens: Cylinder, drum, bowl, cone, basket shape extruder screens.
According to edge processing, extruder screens can be divided into Single Extruder Screen Filters, Spot Welded Extruder Screen Packs, Rim Extruder Screen Packs.
According to layers structure, extruder screens can be divided into Single layer filter disc and Multilayers extruder filter packs.
Application
Extruder screens are an imperative part of the melt filtration process. It is used in plastic and rubber processing machinery to ensure a clean and viable extrusion. Our wire cloth screen for extruder filtration available in various materials, weaves all with a wide spectrum of micron ratings to suit different filter use.
Single Layer Extruder Screens
Single layer extruder screen is lightweight, economical and it can be designed into round, ring, cylindrical, kidney or customized on demands.
Without rims, single layer extruder discs still don’t have sharp edges and are easy to install and fit your extrusion equipment. Being made into various density levels of screens, extruder screen packs can filter many kinds of materials such as polymer melt, oil, powder, food.
Specifications
- Materials: stainless steel, plain steel, brass, copper
- Filtration grade: From 3 μm up to 10 mm
- Weave: Plain, twill, Dutch weave
- Structure: Single-layer network
- Shape: disc, kidney, ring, etc.
Features
- No burrs and easy to operate.
- Good corrosion resistance.
- Made into a variety of shapes.
Applications
Keep impurity particles out from molten materials, solid powder.
Provide services in petrochemical, plastic industry or pharmaceuticals.
Multilayer Extruder Screen Packs with Spot Welded
Multilayer extruder screens are the different wire meshes cut to desired shapes and sizes, and then assembled properly and spot welded with each other to form multilayer packs.
Multilayer screen packs are extra strong, sturdy and convenient for problem free processing. They are assembled in proper sequence to eliminate operator error. The screen pack even prevents any foreign particles in the molten mass from going through the extrusion process. This type of extruder screen is suitable for fine extrusion, and it makes extrusion cleaner and clearer.
Extruder Screen Mesh packs 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. Their edges styles cover spot welded edges and aluminum framing around the spot-welded edges.
Specification：
- Layers: 2, 3 ,4, 5 layers, or other more layers.
- Material: stainless steel, plain steel, brass, copper.
- Filtration grade: From 3 μm up to 10 mm
- Shapes: round, oval, rectangle, kidney shape.
- Frame style: spot welding.
- Feature: high strain ability, filtration capacity, precise fitting filter elements, optimum cost-performance ratio, long lifespan.
Rim Extruder Screen Packs
These are spot welded packs that have an aluminum or stainless steel rim added to them to give the wire mesh filter extra rigidity and strength.
These are excellent for using where the extruder screen filter is operating at high pressures or if there is a danger of contamination getting around the edge of the breaker plate.
Specification
- Material: stainless steel, plain steel, brass, copper
- Filtration grade: From 3 μm up to 10 mm
- Frame: Aluminum, stainless steel, etc.
- Layers: Single layer or multilayer
- Types: Include solid round discs or annulus discs.
Features
- It is durable and strong that makes the screen more effective for plastic or rubber extrusion;
- No burr, no move wire, long service life;
- It can be cleaned repeatedly and economically.
Applications
Rim Extruder Screen Packs are used in the plastic industries to remove the remaining impurities of extrusion. They are predominantly used in the extruded profiles and blown film industries where the contamination of the raw material is less and there is often lower pressure within the extruder head.
Kidney Shaped Filter Screen
Kidney Shaped Filter Screens also known as Kidney Extruder Screens, Horseshoe Extruder screens, they are made from black wire cloth and stainless steel wire cloth, we can make any shape filter screen for extruder and screen changer.
Specification
- Material: stainless steel, plain steel, brass, copper
- Wire Mesh Types: Black wire cloth or Stainless steel wire cloth
- Weaving Method: Plain weave, plain Dutch weave or twill weave
- Layers: Single layer, multi-layers screen packs spot welded
Feature
- Fine cutting without stripping or moving wire
- Spot welding firmly, uniform
- Filtration is precise and efficient
- It can be produced according to your drawings.
Application
- Extrusion and reclamation of plastic, glass.
- Show its abilities of film coating and filtration in blown film, pharmaceutical, oil industries.
