Electroformed nickel screens are deposited around a patterned tool to create thin, repeatable aperture fields. They are distinct from stainless woven cloth and photo-etched foil in material and pore profile.

| Parameter | Specification | Notes |
|---|---|---|
| Construction | Electroformed nickel | Nickel deposited on a patterned mandrel and released as a screen |
| Aperture geometry | Round / square / shaped openings | The working-face opening, outlet profile and deposited thickness define the aperture. |
| Edge / connection | Loose screen / framed screen / backed insert | The electroformed sheet defines the aperture field. The frame or backing defines the supported span, locating surfaces and sealing perimeter. |

Metal is grown on a mandrel or patterned substrate, then released as a screen with a controlled hole or slot shape. The process can create smooth, tapered passages for a defined flow direction. Electroformed nickel screens offer controlled round, square or shaped apertures. Deposited thickness, ligament width and a backing frame are selected together for the aperture pattern and supported span.
The drawing identifies the inlet face, outlet profile, deposited thickness, pitch and ligament width as one aperture construction. The solid border provides the mounting and sealing zone; a frame or backing defines the supported span. Specify the liquid or gas, cleaning chemistry and flow direction for the nickel screen and its support.
Measure the opening at the identified face, the pattern pitch, deposited thickness and solid-border dimensions. Inspect unintended pinholes, continuity of the aperture field and edge integrity. Record flatness and the contact area of the frame or backing as separate assembly dimensions.
ISO 3310-3 covers electroformed-sheet test sieves with round or square apertures from 5–500 µm. ASTM E161 addresses electroformed material and test-sieve construction, using nickel or another metal suitable for electrodeposition. A laboratory sieve specification identifies the standard, aperture shape and nominal size, frame and support arrangement. A custom filter screen drawing defines its own working-face opening, deposited thickness, solid border and mounting interface.
| Process | Metal structure | Aperture definition |
|---|---|---|
| Electroformed nickel | Nickel deposited on a patterned mandrel and released as a screen | Working-face opening, deposited thickness and inlet/outlet profile. |
| Woven nickel mesh | Nickel wires interlaced in warp and weft directions | Wire pair, weave and count in each direction. |
| Photo-etched foil | Solid foil patterned and chemically removed at the openings | Foil thickness, etched wall profile and remaining ligaments. |
| Aperture shape | Standard scope | Unit | Standard and application |
