RT-135 Stainless steel melt filter filtration cartridge

A stainless steel melt filter filtration cartridge is a highly durable, reusable filter used to purify molten materials in demanding environments like polymer extrusion, injection molding, chemical processing, and plastic recycling. These cartridges are engineered to withstand the extreme temperatures, high pressures, and chemical exposure typical of melt filtration processes, making them essential for maintaining product quality and preventing contamination.

• The primary function of these cartridges is to remove contaminants—such as dirt, gels, degraded polymer particles, and metal fragments—from molten polymer or other high-temperature liquids.

• They are ideal for applications where consistent purity and defect-free end products are crucial, including:

• Polymer Extrusion and Injection Molding: Ensures that molten plastic is contaminant-free, which helps prevent flaws in films, fibers, and molded parts.

• Plastic and Polymer Recycling: Filters out impurities in recycled plastics to produce high-quality, reusable material.

• Chemical Processing: Used for purifying molten chemicals and ensuring the consistency and quality of final chemical products.

• Fiber and Textile Production: In synthetic fiber production, it prevents defects that contaminants could cause in the final fibers.

• Material: Typically constructed from 304, 316, or 316L stainless steel due to its resistance to high temperatures, corrosion, and chemical reactivity.

• Filtration Media:

• Sintered Metal: Sintered stainless steel powder provides a rigid, porous structure, suitable for fine filtration and high-temperature applications.

• Woven Wire Mesh: Layers of stainless steel mesh are precisely woven to achieve specific pore sizes, offering durability and precise contaminant capture.

• Perforated Metal Support: Some cartridges incorporate a perforated metal core for added strength, supporting fine filtration media.

• Multi-layer Structure: The cartridges may have multiple filtration layers, including coarse, medium, and fine layers, to trap contaminants at different stages within the cartridge.

• High Temperature and Pressure Resistance: Capable of withstanding temperatures exceeding 300°C and high-pressure conditions, making them suitable for challenging industrial processes.

• Corrosion and Chemical Resistance: Stainless steel construction provides resistance to corrosive chemicals often encountered in melt processing.

• Structural Integrity: Designed to endure high-pressure differentials without collapsing, ensuring long-term reliability.

• Reusability: Unlike disposable filters, stainless steel cartridges can be cleaned and reused, making them a cost-effective option for high-volume operations.

• Precision Filtration: Available in various micron ratings (1–200 microns) to suit specific purity requirements and achieve precise filtration.

• Depth Filtration: Multi-layer designs allow for depth filtration, where contaminants are captured within the filter media rather than just on the surface, enhancing the filter’s lifespan.

• Low Pressure Drop: Designed to balance high filtration efficiency with minimal impact on melt flow rate, ensuring consistent flow and preventing clogging or interruption.

• High Dirt Holding Capacity: Multi-layer and sintered metal designs provide ample capacity to capture contaminants, reducing the frequency of cleaning or replacement.

• Stainless steel cartridges are typically easy to clean, which makes them reusable and extends their lifespan:

• Backflushing: Reverse flow of fluid dislodges trapped particles.

• Chemical Cleaning: Certain solvents or cleaning agents can dissolve or remove contaminants without damaging the filter.

• Ultrasonic Cleaning: Ultrasonic waves help dislodge fine particles within the pores, particularly effective for finer mesh or sintered metal filters.

• Cleaning and reusing the cartridges save on replacement costs and reduce waste.

• Pore Size and Filtration Rating: Depending on the required melt purity, choose a cartridge with the appropriate micron rating to capture specific contaminants.

• Compatibility: Ensure that the stainless steel grade and design are compatible with the melt’s temperature, pressure, and chemical properties.

• Flow Rate and Pressure Requirements: Select a filter that supports the necessary flow rate without causing excessive pressure drop, which could impact production.

• Cost Efficiency: The reusability and durability of stainless steel cartridges reduce operating costs over time.

• High-Quality Output: Consistently removes contaminants, enhancing the quality and uniformity of the final product.

• Reduced Downtime: Durable construction allows for extended use between maintenance intervals, supporting continuous operation in high-demand applications.

• Environmental Benefit: Reusable design means fewer disposable filters, reducing environmental impact and waste.

• Stainless steel melt filter cartridges are often customizable to fit specific equipment or unique process requirements, with options for different sizes, shapes, and micron ratings.

• Adaptable to various filtration setups, these cartridges can be configured for depth filtration, surface filtration, or hybrid filtration systems.
