•Electroformed Precision Screen | Stress-Free Micron High-Precision Filtration & Screening Nickel Mesh

1. Product Introduction 

Electroformed precision screens are integrally manufactured from high-purity nickel and nickel-cobalt alloy via stress-free photolithography electroforming technology. Breaking the precision limitations of traditional woven and punched screens, they serve as core components for high-end precision screening, filtration and classification. Featuring regular uniform meshes, smooth vertical burr-free hole walls and micron-level accuracy, the screens have no splicing seams or internal stress, resisting deformation and loosening during long-term operation. Custom ultra-micro holes, high-density array holes and special-shaped meshes are available with uniform thickness and superior flatness. With self-cleaning, anti-clogging, acid and alkali resistant and high tensile strength properties, they are widely applied in semiconductor slurry filtration, new energy lithium battery material screening, biopharmaceutical purification, precision chemical industry, food powder classification and precision printing, effectively improving filtration accuracy and material purity for high-end precision mass production.

2. Product Features

• Stress-Free Integrated Molding: Formed entirely by photolithography electroforming without weaving, stamping or welding splicing. No residual internal stress ensures no deformation, mesh loosening or warpage during long-term screening and filtration.

• Ultra-High Mesh Consistency: Micron-level precise hole making ensures highly uniform mesh shape, size and spacing. Vertical smooth burr-free hole walls eliminate edge collapse, delivering far higher classification accuracy than traditional screens.

• Self-Cleaning & Anti-Clogging Structure: Adopts tapered holes narrower at the inlet and wider at the outlet for smooth discharging. Powders and slurries are not easily trapped, providing excellent self-cleaning performance and greatly reducing clogging risks.

• Powerful Customization: Custom ultra-micro holes, special-shaped holes, rectangular and circular arrays and non-standard mesh structures are supported. Thickness, aperture and pitch can be precisely customized to match working conditions.

• High Strength & Corrosion Resistance: Nickel-cobalt alloy substrate features high toughness and tensile strength with excellent resistance to acid, alkali and solvent corrosion. Reusable after repeated cleaning with a longer service life than woven and punched screens.

3. Product Performance

• Ultra-High Dimensional Precision: Precisely controlled aperture tolerance with a minimum aperture of 1μm. Minimal full-area mesh error ensures stable particle classification and filtration interception accuracy without leakage or mis-screening.

• Superior Filtration & Screening Performance: Uniform and open porosity ensures high material passing rate and stable screening efficiency. Uniform classified particle size realizes accurate micro-nano grade separation of powders and slurry impurities.

• Structural Stability: Seamless full-panel structure with high flatness and uniform stress distribution, preventing loosening, deformation and damage under high-pressure filtration and high-frequency vibration conditions.

• Environmental Stability: Excellent oxidation, high/low temperature and acid/alkali resistance adapts to complex media conditions in chemical, pharmaceutical and lithium battery industries with stable long-term performance.

• Cleanliness & Durability: Smooth dead-corner-free surface resists impurity adhesion and withstands ultrasonic and chemical cleaning, meeting high-cleanliness precision manufacturing standards.

4. Application Fields

• Semiconductor & Electronics: Precision filtration of photoresist, electronic slurry and wafer cleaning fluid; micro-particle impurity interception to improve semiconductor production yield.

• New Energy Lithium Battery: Precision screening and filtration of lithium battery positive and negative electrode powder, electrolyte and diaphragm slurry to enhance battery material purity and cycle stability.

• Biopharmaceuticals: Medical liquid filtration, biological reagent purification, pharmaceutical powder classification and sterile screening, complying with high-cleanliness medical production standards.

• Precision Chemical Industry: Filtration and classification of fine chemical powders and catalyst particles for refined material purification.

• Food & Daily Chemicals: Precision filtration and screening of food powder, dairy products and cosmetic raw materials to ensure raw material fineness and product quality.

• Precision Printing: Screen printing, ink filtration and slurry homogenization screening to ensure uniform and smooth printing coating.
