Precision Electroforming ServicesShenzhen Zhuolida

Shenzhen Zhuolida is a trusted, experienced manufacturer offering fullrange precision electroforming services for highaccuracy custom micrometal components. By combining highresolution photolithography and additive electrochemical metal deposition technology, we produce burrfree, lowstress metal parts with micronlevel dimensional consistency that is difficult to achieve by stamping, laser cutting, CNC machining or chemical etching. With decadeslong expertise in micrometal fabrication, inhouse production workshops and strict metrological qualitycontrol systems, we provide complete solutions covering design optimization, rapid prototyping, smallbatch trial production and massvolume manufacturing for global clients across medical, newenergy, optical instrumentation, semiconductor, filtration and industrial precisionequipment sectors.

1. Introduction to Our Precision Electroforming Technology

Electroforming is an additive metalgrowing manufacturing process without any mechanical cutting force applied to finished components. At Shenzhen Zhuolida, every electroformed part originates from your 2DCAD drawing or sample specifications. Our engineering team converts your design into a highprecision glass photomask, then transfers micropatterns onto a highly polished conductive mandrel substrate through UVexposure and photoresist development. The patterned mandrel is submerged inside our temperaturecontrolled electrolyte bath. Puremetal ions are reduced and slowly deposited atombyatom on exposed conductive regions, while photoresistcovered zones block metal growth and form clean, sharplydefined apertures and contours.

After reaching the target thickness, the selfsupporting metal component is carefully peeled off the mandrel. Subsequent surfacefinishing, stressrelief heattreatment and multistage microscopic inspection are carried out before final shipment. Since all geometric features are optically fixed before metal deposition, finished parts are completely free from stampinginduced deformation, laser heataffected zones, toolwearrelated drift and burr defects.

Our available electroforming materials mainly include highpurity nickel, nickelcobalt alloy, copper and gold. Different material selections meet customer requirements for electrical conductivity, corrosionresistance, hardness, magnetic performance and biocompatibility. Component thickness can be precisely adjusted within 5 μm200 μm according to application demands.

2. OneStop Electroforming Service Workflow at Shenzhen Zhuolida

We implement fullprocess inhouse manufacturing without outsourcing key procedures, ensuring stable leadtime, consistent quality and flexible customization capability.

Step 1: DFE (Design for Electroforming) Consultation & Manufacturability Review

Once we receive your drawings, our electroforming engineers conduct a thorough technical evaluation. We examine apertureratio limits, minimum webbar width, feature spacing, wallthickness constraints and potential formingrelated risks. Practical designoptimization suggestions are offered to improve production yield, enhance dimensional stability and cut unnecessary manufacturing costs while preserving your functional requirements. Rapid feedback on quotation and sampling schedule will be provided within 12 working days.

Step 2: HighResolution Photomask & Conductive Mandrel Fabrication

After design confirmation, highprecision glass photomasks are produced for pattern transfer. A smooth, defectfree conductive base plate is mechanically polished, chemically degreased and coated with a specialized release agent. This releaseagent layer guarantees clean separation of finished electroformed parts from the mandrel surface after deposition.

Step 3: Photolithography Patterning

Photosensitive liquid photoresist is spincoated onto the mandrel to achieve uniform filmthickness. Ultraviolet light transfers micropatterns from the photomask. Developer solution removes exposed photoresist and reveals precise conductive microzones where metal will grow. Sharp, clean pattern edges created in this lithography phase directly determine final aperture accuracy.

Step 4: ClosedLoop Controlled ElectroDeposition

The patterned mandrel is suspended inside our automated electrolyte tank. Our production technicians strictly monitor and regulate bath temperature, pHvalue, currentdensity, metalion concentration and electrodeposition duration. Slow, stable metalion reduction builds dense, lowstress metal layers. Special anticlogging bellmouth tapered hole profiles, thickened integrated border frames and other customized structures can be formed during this electrogrowth stage.

Step 5: Demoulding & Component Separation

When metal deposition is completed, finished thinmetal components are slowly and evenly peeled away from the mandrel substrate. Our operators follow strict operating procedures to prevent stretching, bending or twisting delicate microfeatures, which would cause permanent dimensional distortion.

Step 6: CustomTailored PostProcessing

A comprehensive selection of secondary finishing services is available upon your request:  Electropolishing to smooth aperture inner walls and flat surfaces  Thermal stressrelief annealing for residualstress elimination  Precision laser edgetrimming  Surface passivation treatment for improved corrosion resistance  Surface plating: gold, silver, blacknickel and other functional coatings  Meshtoframe bonding, assembly into standard testsieve frames or support fixtures  Ultrasonic particlefree final cleaning

Step 7: MultiStage QualityControl & Metrological Inspection

Every batch undergoes our rigorous inhouse inspection workflow. Our qualitycontrol items include aperturedimension measurement, dimensionaltolerance verification, flatness testing, openarearatio validation, highmagnification microscopic defect scanning and surfaceroughness checking. Inspection reports, dimensional test data and certification documents can be supplied for laboratorygrade precision parts.

4. Core Advantages of Choosing Shenzhen Zhuolida as Your Electroforming Partner

1. Outstanding micronlevel dimensional accuracy We can deliver typical dimensional tolerances of ±12 μm. Largearea electroformed mesh sheets maintain extremely consistent aperture geometry, delivering highly repeatable performance for filtration, particletesting and opticalcalibration applications.

2. Monolithic, burrfree and stressfree metal structure Electroformed parts are grown as onepiece metal sheets, without wireintersection knots, punching burrs, laser slag or residual mechanical stress. Smooth hole walls drastically reduce particletrapping risk, improve anticlogging behaviour and simplify repeated cleaning cycles.

3. Highlevel designcustomization flexibility Aperture shape, holesize, webbar width, component thickness and outer contour can all be adjusted independently, free from wovenwirediameter restrictions. Onepiece reinforced border frames can be electroformed together with mesh sections, removing extra welding or assembly costs.

4. Stable material performance and long servicelife Our highpurity electroformed nickel components feature uniform internal microstructure, excellent electrical conductivity and reliable corrosionresistance. Unlike plated metal parts, electrodeposited metal has no risk of surfacecoating peelingoff during longterm operation.

5. Balanced rapid sampling and massproduction capability With independent electroforming production lines, we support fast prototype turnaround for smallbatch custom orders, while maintaining highyield, stable largevolume production for industrial customers.

5. Target Application Industries

 Medical & lifescience: diagnostictesting components, microfluidic chips, nebulizer plates, laboratory precision test sieves  Newenergy industry: hydrogenelectrolysis equipment, lithiumbattery currentcollector mesh, fuelcell auxiliary components  Opticalinstrument manufacturing: optical masks, lightdiffusion screens, laseraperture components  Semiconductor & electronics: precision shielding mesh, testfixture microparts, ultrafine SMT stencils  Industrial filtration & powderprocessing: aerosol sampling screens, ink filters, foodgrade finesieving components

6. Design Guidance & Process Boundary

 Minimum stable aperture: approx. 2 μm  Ultrathin electroformed parts (thickness below 10 μm) are mechanically delicate and may require supporting frames for heavyduty environments  When opening sizes exceed 200 μm, alternative manufacturing technologies such as chemicaletching or stamping usually deliver better costperformance  Adding small inner radii to sharp corners will significantly improve electroforming production yield.

Earlystage DFE consultation with our engineering team can help you avoid costly redesign delays and optimize both part quality and production leadtime.
