High-Temperature Resistant Sintered Melt Filters

       Our sintered melt filter elements are meticulously crafted from premium 316L stainless steel (304 stainless steel is also available at a more affordable price). These filters are manufactured using advanced high-temperature vacuum sintering technology and feature a precise multi-layered mesh structure, specifically designed to meet the stringent requirements of polymer melt filtration in core industrial sectors.

　　Our filters are ideal for plastic extrusion, fiber spinning, plastic granulation, and film production lines, effectively removing contaminants from high-temperature polymer melts. By ensuring superior melt purity, they enable stable, continuous production, guarantee finished product quality, and significantly reduce costs, providing an ideal solution for businesses to optimize efficiency, reduce waste, and increase operating profits.

　　Key Performance Data

　　Temperature Resistance: Stable continuous operation at temperatures up to 350°C, with short-term high-temperature resistance up to 400°C. Even under prolonged exposure to extreme temperatures, the filters maintain stable performance, preventing material degradation or deformation.

　　Pressure Resistance: Withstands operating pressures up to 30 MPa. Even under extreme pressure conditions, the filters remain leak-proof, structurally intact, and will not deform or fail, ensuring safe and stable operation in high-pressure extrusion and spinning systems. Filtration Accuracy: Customizable filtration accuracy, ranging from 1μm to 100μm. Highly uniform pore size distribution with an error rate ≤±5% allows for precise control of impurity retention, meeting diverse application requirements.

　　Impurity Removal Efficiency: Impurity removal rate up to ≥99.5%, effectively capturing gel particles, black spots, carbonized particles, and other harmful impurities in the polymer melt. This directly eliminates surface defects and performance issues in the finished product, thereby improving overall product quality.

　　Lifespan: Lifespan is 6-24 months, with an average lifespan of approximately 12 months under normal operating conditions, far exceeding standard disposable filter products.

　　Reusable and Cleanable: Supports at least 10 cycles of washing and reuse. After each washing, the filtration efficiency remains above 95%, ensuring stable performance after multiple uses and minimizing replacement frequency.

　　Customization Options

　　We offer fully customized solutions, ensuring seamless compatibility with your existing equipment and supporting a wide range of specifications and connection methods:

　　Size Customization: Customizable outer diameter (50mm-200mm) and length (50mm-1200mm) to suit different equipment models and installation spaces.

　　Connection Compatibility: Fully compatible with flange connections, threaded connections, and quick-connect interfaces, meeting the connection standards of 99% of mainstream extrusion, spinning, and granulation equipment on the market.

　　Material Flexibility: 316L stainless steel provides superior corrosion resistance in harsh chemical melt environments; 304 stainless steel offers cost-effective performance under standard industrial conditions.

　　Core Advantages (Data Support)

　　1. Significantly Reduced Costs

　　Compared to traditional disposable filters, replacement frequency is reduced by 80%, directly lowering annual replacement costs. For a company producing 10 tons of plastic pellets per day, this translates to annual savings of over $15,000. 

       1. Beyond Direct Procurement Costs: Reduced replacement frequency minimizes production downtime and maintenance costs, resulting in an overall operating cost reduction of at least 60% annually.

　　2. Unparalleled Production Stability:This filter can operate continuously and stably for ≥8000 hours with minimal performance degradation—filtration efficiency decreases by no more than 5% over its entire service life. This stability significantly reduces unplanned downtime by over 70%, ensuring uninterrupted production. Maintaining stable melt purity also helps reduce defect rates, further improving production efficiency and economic benefits.

　　3. Superior Structural Reliability: The filter features a robust sintered structure with superior mechanical properties: tensile strength ≥350MPa and compressive strength ≥500MPa. Even under extreme pressure fluctuations and high-flow-rate melt scouring, the filter maintains structural integrity, preventing collapse, breakage, or filter media detachment. This eliminates the risk of secondary contamination and ensures long-term reliable operation of production equipment.

　　4. Efficient and reliable delivery:For standard specifications, we maintain a fast delivery cycle to meet urgent production needs. For customized solutions, the entire design, production, and delivery process is completed within 15 days, ensuring zero impact on your production progress and supporting timely equipment maintenance and upgrades.
