Filter Media – Sintered Metal Fiber Felt
Sintered metal fiber felt is produced by randomly layered metal fibers bonded through high-temperature sintering, forming a three-dimensional porous structure optimized for melt filtration.
Key characteristics:
Uniform pore size distribution
High porosity and permeability
Excellent mechanical stability under high differential pressure
Resistant to deformation and fiber migration
Typical Materials
Melt filter elements are available in the following materials depending on polymer type and operating conditions:
Stainless Steel (304 / 316L / 310S)
Material selection is based on melt temperature, chemical composition, pressure, and cleaning requirements.
Operating Performance
Typical operating temperature:
up to 300–500°C (material-dependent)
Operating pressure:
Suitable for high-pressure melt filtration systems
Filtration rating:
Typically from 1 μm to 100 μm
High contaminant retention capacity with stable pressure increase behavior
Filter Element Designs
Our sintered fiber felt melt filters can be supplied in multiple configurations:
Candle filter elements
Disc filters
Pleated or multi-layer composite structures
Custom geometries based on customer drawings
All elements are designed for direct integration into melt filtration housings.
Cleaning & Regeneration
Sintered metal fiber felt filter elements are fully cleanable and reusable, supporting multiple regeneration cycles by:
Backflushing
Solvent cleaning
Thermal cleaning (burn-off)
Chemical cleaning (material-compatible)
This significantly reduces operating costs compared to disposable filter media.
Typical Applications
Polymer extrusion lines
Plastic film and sheet production
Fiber and nonwoven manufacturing
Compounding and masterbatch processing
Recycling and reprocessing of polymer melt
Key Advantages
Stable melt flow and pressure control
Improved product surface quality
Protection of spinnerets, dies, and downstream equipment
Long service life under continuous operation
Reduced downtime and filter replacement frequency
Customization & Engineering Support
All melt filter elements are engineered-to-order based on:
Polymer type and contamination level
Melt temperature and operating pressure
Required filtration efficiency
Housing interface and installation constraints
Our engineering team supports media selection, structural optimization, and system compatibility to ensure reliable long-term operation.
