As one of professional nickel mesh electroforming manufacturers, Shenzhen Zhuolida focuses on custommade electroformed nickel mesh relying on mature electrochemical deposition technology. Different from woven nickel mesh and chemicallyetched metal mesh, electroformed nickel mesh is built by depositing highpurity nickel onto precision photolithographic mandrels. The finished mesh features seamless integral structure, burrfree hole walls, consistent aperture dimension and stable electrical conductivity. These superior performances make electroformed nickel mesh widely adopted in newenergy batteries, fuelcell electrodes, semiconductor filtration, medical separation, chemical electrolysis and precision screening fields.

Traditional woven nickel mesh suffers from woven knots, uneven aperture, wire displacement and poor dimensional repeatability. Chemicaletched nickel mesh is subject to isotropic sideetch constraints for ultrafine microholes. Electroforming overcomes these bottlenecks. It can stably produce ultrathin nickel mesh with aperture ranging from several microns to hundreds of microns, controlling dimensional tolerance down to ±12 μm. Openarea ratio, hole shape, mesh thickness and outer contour can be fully customized according to customer CAD specifications.

1. Complete Electroforming Workflow for Nickel Mesh

Step 1: DFM Evaluation & Mandrel Fabrication

Engineers conduct DFM review for nickel mesh drawings, analyse aperture size, web width, openarea ratio, mesh thickness and panel layout. Considering nickel deposition characteristics, pattern compensation is added for electroforming mandrel. Highprecision lithography is implemented to manufacture conductive mandrel with accurate micropattern. Unrealistic microfeatures will be fed back for drawing optimisation.

Step 2: Mandrel Surface PreTreatment

The patterned mandrel goes through multistep cleaning and surface activation. Oil, particles and oxide layers are completely removed. Surface treatment controls interfacial adhesion force, ensuring electrodeposited nickel can be separated smoothly without mesh deformation or tearing after production. Improper pretreatment will cause partial nickel peeling, mesh breakage and batch scrap.

Step 3: Nickel ElectroDeposition

The treated mandrel is placed inside dedicated nickel electroforming bath. Highpurity nickel ions are deposited uniformly under controlled current density, bath temperature and solution circulation. Nickel layer thickness grows steadily to reach target mesh thickness. Current parameters are strictly adjusted to guarantee uniform deposition across the whole mesh area, avoiding thickness deviation between central and edge zones. Highpurity nickel material ensures excellent electrical conductivity and corrosionresistance for final mesh products.

Step 4: Separation & Initial Inspection

After deposition completes, the nickel mesh is carefully peeled off from mandrel. The original micropattern is fully transferred onto nickel components. Preliminary visual inspection checks for cracks, local missing patterns and surface defects. Damaged semifinished parts are eliminated in advance.

Step 5: PostTreatment Process

Posttreatment includes chemical cleaning, degreasing, stressrelief treatment and precision drying. For highend applications such as medical devices and semiconductor filtration, highpurity deionised water circulating cleaning is adopted. Surface modification like passivation can be done upon customer requirements to further enhance oxidationresistance.

Step 6: Metrology & FullArea AOI Quality Testing

Multiple inspection methods are applied: micrometre equipment verifies mesh thickness, aperture tolerance and web width. Automatic Optical Inspection scans full mesh surface to detect tiny cracks, pinholes and pattern defects. For electrodegrade nickel mesh, conductivity test and openarearatio verification are performed. All batch process parameters and inspection records are archived for full traceability. Qualified products are cut, packed and delivered.

2. Core Product Advantages of Electroformed Nickel Mesh

Ultrahigh dimensional consistency: Integral electrodeposition forming, no woven joints. Aperture tolerance can reach ±12 μm. Every hole maintains identical geometry, delivering stable filtration and conductive performance.

Burrfree and smooth hole wall: No mechanical stamping or cutting force during manufacturing. Smooth inner hole surface reduces particle capture, very suitable for precision filtration and electrode currentcollector scenarios.

Highpurity nickel material: Adopt highpurity nickel raw material, featuring outstanding electrical conductivity, alkaliresistance and moderate acidresistance, adaptable to complex electrochemical working conditions.

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

Good mechanical property: Uniform internal stress distribution, excellent tensile strength, not easy to deform under vibration and flow impact, longer service life compared with conventional woven nickel mesh.

3. Typical Application Scenarios

 New energy industry: battery current collectors, fuelcell electrode base mesh, electrolytic reaction electrode components  Semiconductor industry: precision filter mesh for chemical slurry, particle separation mesh  Medical & biotech: sterile filtration, biosample separation mesh  Chemical industry: electrolysis electrode mesh, corrosivemedium filtration screen  Precision testing: laboratory test sieve mesh, particlesizeanalysis components

4. Process Limitations

Electroformed nickel mesh has cost disadvantages for extralarge simplepattern mesh. Minimum feature size is restricted by electrodeposition capability. Strict bathsolution maintenance is required during whole manufacturing procedure. For coarsemesh lowcost requirements, woven nickel mesh may provide more economical solutions.
