Electroformed Perforated Plate Manufacturing and Applications

1. Product Introduction

Electroformed nozzle plates are core precision fluid control components integrally molded with high-purity nickel-cobalt alloy through stress-free photolithography electroforming technology. Different from traditional drilling and etching processes, the whole process involves no mechanical stress or thermal deformation. The product supports micron-level ultra-precision micro-hole array molding with vertical, smooth, burr-free hole walls and extremely high aperture consistency, fundamentally solving industrial problems such as nozzle blockage, uneven flow, atomization deviation and liquid leakage. Featuring uniform thickness, excellent flatness, high pressure resistance, corrosion resistance, erosion resistance and easy cleaning, it supports customization of special-shaped holes, stepped flow channels and high-density array holes. Widely used in industrial inkjet printing, fluid atomization, medical microfluidics, new energy spraying, automotive fuel injection and precision cooling fields, it is an essential core precision part for high-end fluid injection equipment.

2. Product Features

• Stress-Free Integrated Molding: Molded by pure photolithography electroforming without stamping, drilling or laser processing damage. Zero internal stress ensures no warpage or deformation under long-term high-pressure operation.

• Ultra-High Microhole Precision: Micron-level precise hole opening with vertical and clean hole walls, no burrs, edge collapse or taper deviation. Tens of thousands of micro holes on a single plate maintain ultra-high dimensional consistency.

• Excellent Fluid Performance: Smooth hole walls reduce fluid resistance, ensuring uniform liquid output and stable injection with fine and consistent atomized particles, avoiding offset, scattered and intermittent spraying.

• Comprehensive Customization: Custom ultra-thin plates, micro-apertures, special-shaped nozzles, multi-layer stepped flow channels and high-density array structures are available with customized molds.

• Durable & Clog-Resistant: Smooth inner walls without dirt accumulation dead corners resist acid and alkali corrosion as well as high-pressure fluid erosion. Repeated cleaning is allowed, with a far longer service life than traditional nozzle plates.

3. Product Performance

• Dimensional Precision: Microhole aperture tolerance ±0.002mm with accurate hole position. The overall plate flow error is controlled within 3% with excellent batch consistency.

• Fluid Injection Performance: Extremely low hole wall roughness reduces fluid resistance, ensuring stable linear injection and high atomization uniformity to meet high-precision micro-fluid control requirements.

• Structural Stability: High flatness and uniform thickness ensure tight assembly and good sealing performance with no liquid seepage, leakage or pressure relief under high-pressure working conditions.

• Environmental Resistance: Nickel-cobalt alloy substrate features oxidation resistance, acid and alkali resistance, and high and low temperature resistance, adapting to complex fluid media and continuous mass production working conditions.

• Cleanliness & Durability: Dead-corner-free structure prevents impurity accumulation and hole blockage, suitable for high-cleanliness production scenarios with no precision attenuation after repeated cleaning.

4. Application Fields
