Photo-etched filter discs
Thin photo-etched disc with drawing-defined hole or slot pattern.
Product detailsDrawing-based manufacturing
Etched and electroformed screens
Thin etched-foil and electroformed screens for small apertures and patterned inserts. Etching removes metal from foil; electroforming deposits metal on a tool. Thickness, aperture profile and handling therefore differ.

Select the process around the aperture
- Etched foilLateral etching affects web width and aperture profile. Foil thickness constrains the smallest practical feature; a thickness change needs renewed feasibility assessment.
- ElectroformingMetal is deposited on a patterned mandrel. An electroformed nickel screen differs materially and mechanically from rolled stainless foil.
- IntegrationDefine the carrier frame, working face and sealing land. Specialist media can be incorporated into a component without presenting the source process as an in-house production line.

Etched and electroformed screens
Applications
For compact flow paths with controlled aperture patterns.
Instrument screens
Thin patterned inserts in compact passages.
Fine-aperture discs
Active and sealing areas defined in one foil profile.
Specialist OEM components
Electroformed patterns for applications that call for that material and process.
Inspect without damaging the foil
Optical measurement and protected handling suit fragile screens.
01DimensionsCheck apertures, web width and pattern registration.
02Foil conditionInspect tears, creases, blocked holes and residue.
03MountingCheck support and restraint without crushing or stretching the active area.

Questions before ordering
Is electroformed nickel equivalent to stainless mesh?
No. Material, production route, stiffness, corrosion compatibility and cleaning behavior differ. Use the actual material designation.
Can foil thickness change without affecting the screen?
A change can alter opening feasibility, undercut, stiffness and pressure loss. It is a specification change, not an automatic substitution.
When does a precision foil need a support frame?
Thin etched or electroformed foil can deform in handling or under differential pressure. Specify the free span and fixing method so the backing frame does not cover critical openings.
