Product Overview
What is a Welding Mesh Disc?A welding mesh disc is a precision-engineered filtration component made from one or more layers of wire mesh (usually stainless steel). These layers are cut into circular or custom shapes and securely joined together using advanced spot welding or edge-binding techniques.By welding multiple layers of different mesh counts together, these discs combine high mechanical strength with fine filtration ratings, preventing the mesh from shifting or distorting under high-pressure environments. -
Common Specifications
Key Specifications of Welding Mesh DiscsWhen sourcing welding mesh discs for your machinery, understanding the technical specifications is crucial for ensuring compatibility and performance. We offer fully customizable options tailored to your exact blueprints:1. Material OptionsThe choice of material determines the disc's resistance to corrosion, temperature, and chemicals.Stainless Steel (SS 304, 304L, 316, 316L): The industry standard for excellent corrosion resistance, high-temperature tolerance, and food-grade hygiene.Galvanized Steel: An economical choice for low-corrosion environments.Special Alloys (Inconel, Monel, Hastelloy): For extreme chemical and thermal applications.2. Layer ConfigurationSingle-layer Mesh Discs: Ideal for simple, low-pressure straining and coarse filtration.Multi-layer Welding Mesh Discs (2 to 7+ layers): Combining coarse support mesh with ultra-fine filtration mesh. Spot welding keeps the layers perfectly aligned to handle high pressure.3. Mesh Type & Filtration RatingWoven Wire Mesh: Plain weave, twill weave, or Dutch weave depending on the required micron rating.Filtration Range: From 5 microns up to 1000+ microns, allowing you to capture everything from microscopic particulates to larger debris.4. Dimensions & ShapesDiameter: Ranging from 10 mm to over 1000 mm.Shapes: While circular discs are the most common, they can also be manufactured in oval, rectangular, ring-shaped, or custom geometries to fit specific extruder barrels or filter housings. -
Application Area
Core Applications Across IndustriesThanks to their rigid structure and precise filtration capabilities, welding mesh discs are vital components in several high-demand sectors:1. Plastics and Polymer ExtrusionIn plastic recycling and polymer manufacturing, extruder screen packs (multi-layer welded discs) are used to filter out impurities from molten plastics. The welded design prevents the layers from separating under the immense pressure of the extrusion process.2. Chemical and Petrochemical RefiningUsed in the filtration of aggressive chemicals, oils, and petroleum products. Stainless steel welding mesh discs can withstand harsh chemical reactions and high working temperatures without degrading.3. Water Treatment and DesalinationPerfect for industrial water purification systems, backwash filters, and water softening equipment, acting as a reliable barrier against suspended solids.4. Food, Beverage, and PharmaceuticalsWith food-grade stainless steel (SS316L), these discs are widely used in food processing, beverage straining, and pharmaceutical manufacturing where hygiene and zero contamination are mandatory. -
