Focusing on filtration screens
filters, strainers, baskets, cones, cartridges
YMX supplies custom wire mesh filter discs and screen packs for polymer processing, liquid filtration, gas filtration and industrial screening systems. Products are available as single-layer discs, multilayer screen packs, spot-welded packs, framed discs and micron-rated filter elements.
Diameter, shape, mesh specification, filtration accuracy, layer sequence and edge construction can be manufactured according to drawings, samples or equipment dimensions.
Single-layer filter discs are suitable for basic screening and particle retention. They can be manufactured from plain weave, twill weave or Dutch weave wire mesh.
Available options include:
Round, square, oval and custom shapes
Plain-cut or reinforced edges
Custom outside and inside diameters
Different mesh counts and wire diameters
Stainless steel material options
Disposable or reusable designs
Multilayer screen packs combine different mesh layers to achieve the required filtration accuracy and mechanical strength.
A typical structure may include:
Fine filtration mesh
Coarse supporting mesh
Protective outer mesh
Flow-distribution layer
The number and order of layers can be customized according to the flow direction, pressure differential and required filtration performance.
Extruder screen packs are used in plastic and polymer processing equipment to remove contaminants from molten material before extrusion.
Available designs include:
Single extrusion screens
Two-layer screen packs
Multilayer screen packs
Spot-welded screen assemblies
Fine mesh with coarse support layers
Custom screens made to breaker plate dimensions
For quotation, please provide the outside diameter, mesh sequence, number of layers, processed material and required quantity.
Framed filter discs use a metal rim to secure the wire mesh and protect the outer edge. The frame helps maintain dimensional stability during installation, removal and cleaning.
Framed designs are suitable when:
Fine mesh requires edge protection
The disc must maintain a precise diameter
Repeated installation is required
The filter needs to be cleaned and reused
Loose mesh edges may affect sealing
Micron-rated filter discs are manufactured according to the required particle retention level.
The final specification should consider:
Required micron rating
Mesh weave
Wire diameter
Open area
Flow rate
Fluid viscosity
Pressure differential
Supporting structure
A micron rating alone does not define the complete filter. Mesh construction and support requirements must also be confirmed.
Each layer in a multilayer screen pack has a specific function.
Filtration Layer
Captures particles according to the required mesh size or micron rating.
Support Layer
Supports the fine filtration mesh and reduces deformation under pressure.
Protective Layer
Protects the filtration layer during installation, handling and cleaning.
Flow-Distribution Layer
Helps distribute the filtered material across the available surface area.
The layer sequence should follow the operating flow direction. Incorrect layer arrangement may increase pressure loss or damage the fine mesh.
Finer mesh provides improved particle retention but also increases flow resistance. The correct filter disc should balance filtration accuracy with acceptable pressure drop.
Important selection factors include:
Mesh opening
Wire diameter
Weave type
Number of layers
Effective filtration area
Fluid or polymer viscosity
Flow rate
Contamination level
Maximum allowable pressure differential
Applications involving fine filtration or higher pressure may require additional supporting layers.
YMX can customize:
Outside diameter
Inside hole diameter
Disc shape
Mesh count
Micron rating
Wire diameter
Mesh weave
Number of layers
Layer sequence
Supporting mesh
Spot-welding pattern
Frame material
Frame width and thickness
Edge treatment
Packaging quantity
Customers can submit CAD drawings, dimensional sketches or existing samples for technical review.
Filter discs and screen packs can be inspected according to approved drawings and specifications.
Inspection items may include:
Material verification
Mesh count
Wire diameter
Disc dimensions
Inside hole dimensions
Layer quantity
Layer sequence
Flatness
Spot-weld integrity
Frame dimensions
Edge condition
Surface cleanliness
Flow-direction identification
For multilayer packs, the mesh sequence should be checked before packaging.
Samples and small-batch orders can be evaluated for custom filter disc projects. MOQ depends on the material, dimensions, mesh specification, number of layers, frame structure and processing requirements.
Simple single-layer discs generally require less preparation than multilayer, framed or specially shaped products. New designs may require drawing approval and sample verification before batch production.
Sample and production lead times are confirmed after the specifications, processing requirements and order quantity have been reviewed.
