As experienced electroformed mesh manufacturers, Shenzhen Zhuolida delivers onestop custom electroformed mesh solutions based on mature electrochemical deposition technology. Electroformed mesh differs fundamentally from woven mesh and chemically etched mesh. It is manufactured by depositing target metal material onto precision lithographyproduced conductive mandrels. After deposition, the metal sheet is peeled off from the mandrel to obtain an integral mesh structure. This unique manufacturing method delivers smooth burrfree hole walls, highly consistent aperture sizes and stable mechanical and electrical performance, making electroformed mesh irreplaceable for many highend industrial scenarios.

Conventional woven mesh is limited by weaving process, featuring interlaced knots, shifting wires and inconsistent apertures. Chemicaletched mesh suffers from isotropic sideetching, which brings constraints when producing ultrafine microholes. Electroforming breaks through these technical bottlenecks. It supports flexible customization of aperture, web width, mesh thickness, openarea ratio and outer contour according to customer CAD drawings. Available materials include highpurity nickel, nickelcobalt alloy, copper and other electroformable metals. Dimensional tolerance can reach ±12 μm for critical microfeature requirements.

1. Complete Electroforming Production Workflow for Electroformed Mesh

Step 1: DFM Review & Conductive Mandrel Fabrication

Process engineers perform DFM evaluation on customer mesh drawings. Key parameters including aperture, web width, openarea ratio, thickness and panel nesting layout are analysed. Pattern compensation is added for electroforming mandrel according to metal deposition characteristics. Highprecision photolithography produces conductive mandrels with accurate micropatterns. Unrealistic tiny features will be identified and fed back for drawing optimisation. Qualified mandrels are prepared for subsequent electrodeposition.

Step 2: Mandrel Surface PreTreatment

Patterned mandrels go through multistage cleaning, degreasing and surface activation. All surface oil, particles and oxide layers are fully removed. Surface interfacial adhesion is precisely controlled. This ensures deposited metal can be smoothly separated after electroforming without mesh tearing, deformation or partial peeling. Improper pretreatment will trigger local missing patterns and largebatch scrap.

Step 3: Metal ElectroDeposition

Prepared mandrels are immersed in dedicated electroforming bath. Under precisely controlled current density, bath temperature and solution circulation, metal ions deposit uniformly on mandrel surface. Metal layer grows gradually until target mesh thickness is achieved. Realtime parameter adjustment guarantees uniform thickness across the whole mesh surface, avoiding thickness deviation between central area and edges. Material purity is strictly controlled to secure corrosionresistance and electrical performance of finished mesh.

Step 4: Peeling and Preliminary Inspection

Once deposition procedure finishes, electroformed mesh is carefully separated from mandrel. Micropattern is completely transferred onto electroformed metal components. Operators carry out preliminary visual inspection to detect cracks, fractures and local pattern loss. Defective semifinished products are eliminated before posttreatment to reduce followup waste.

Step 5: MultiStep PostTreatment

Posttreatment workflow varies by application scenarios. Standard processes include chemical cleaning, degreasing, stress relief and precision hotair drying. For semiconductorgrade and medicalgrade electroformed mesh, circulating highpurity deionised water cleaning is adopted. Passivation and other surface modification treatments can be implemented upon customer request to enhance antioxidation and anticorrosion performance.

Step 6: Comprehensive Metrology & AOI FullScan Inspection

Multiple testing methods are applied for quality verification. Micrometrology instruments test mesh thickness, aperture tolerance and web dimension. Automatic Optical Inspection performs fullsurface scanning to detect microcracks, pinholes and pattern distortion. For electrodegrade and filtergrade mesh, additional tests such as openarearatio verification and conductivity test are available. All batchrelated process parameters and inspection records are archived for complete traceability. Qualified electroformed mesh products are cut, packed and delivered.

2. Core Advantages of Custom Electroformed Mesh

Excellent dimensional repeatability: Integral electrodeposition forming without weaving joints. Every single hole maintains consistent geometry, delivering stable filtration, separation or currentcollection performance in continuous operation.

Smooth burrfree inner hole wall: No mechanical stamping, cutting or laser melting force during manufacturing. Smooth hole surface reduces particle trapping, greatly lowering clogging risk for precision filtration applications.

High design flexibility: Supports round, square, rectangular, hexagonal and custom irregular hole shapes. Mesh thickness, aperture and openarea ratio can be adjusted independently. Both smallbatch prototype trialrun and largevolume mass production are supported.

Reliable material performance: Multiple electroformable metal options satisfy requirements for electrical conductivity, alkaliresistance, acidresistance and mechanical tensile strength for different working media.

Stable mechanical property: Uniform internal stress distribution. Electroformed mesh shows good tensile strength and antideformation capability under fluid impact and vibration, extending service life compared with traditional woven mesh.

3. Main Industrial Application Fields

 New energy industry: fuelcell electrode mesh, battery current collector, electrolysis reaction functional components  Semiconductor industry: chemical slurry precision filter mesh, particle separation screen  Medical and biotechnology: sterile filtration, biological sample separation components  Chemical industry: electrolysis electrode mesh, corrosive medium filtration screen  Laboratory & precision testing: test sieve mesh, particle size analysis components

4. Process Limitations

Electroformed mesh has relatively higher cost for extralarge simple coarsemesh products. Minimum feature dimension is constrained by electrodeposition technical capacity. Continuous bathsolution maintenance is required during mass production. For lowcost coarsemesh requirements, woven mesh may provide better economic benefit.
