Plastic Mesh Cores & Cages for Filter Elements
Extruded plastic netting in rigid mesh tube form that provides structural support as a center core in filter cartridges. Rigid mesh cages are also used as outer containment sleeves to protect filter media from damage during handling and cleaning.
The ready availability of a wide range of configurations and the minimal tooling costs associated with custom designs make extruded mesh cores a favorite for filter design engineers.
Measurements & Tolerances
Plastic Rigid mesh tubes are extruded and stocked in common lengths with a "rough cut" length tolerance of +/-0.25".
To create more precise custom lengths extruded tubes can be "finished cut". The finished cut tolerance is +/-0.030" for lengths less than 46 inches or +/-0.060" for lengths from 46 to 94 inches.
Tube diameters can slightly differ from lot-to-lot due to shrinkage variability. Inside Diameter (ID) and Outside Diameter (OD) tolerances are typically +/-0.020" for most configurations.
Chose from a wide range of diameters, apertures, and open areas to get the flow characteristics and structural support required for your application. Don’t see what you need below?
We also custom fabricate plastic mesh tubes from a variety of flat mesh or nonwoven products.
