Overview

A filter screen etching manufacturer differs from a trading supplier in where the work actually happens. Coating, exposure, development, etching, stripping, finishing and final inspection all sit under one roof, so a drawing goes straight onto a production line instead of being brokered to a third party. Panels are processed on spray-etch lines handling 500 × 1000 mm sheets, and every enquiry is reviewed by a process engineer before quotation, because aperture size, open area and ligament width decide whether a filter screen can be etched at all.

The parts themselves are through-etched sheets with a defined hole field, a solid rim for sealing, and often a taper that widens toward the dirty side of the flow. Stainless steel 304/316L, nickel 200, copper C110 and titanium Gr2 run from 0.03 mm foil to 1.20 mm plate, with apertures from 0.05 mm to 3.0 mm and open area from 15% to 72%. Because the same plant does the photoresist work, the etching and the electropolishing, a filter screen etching manufacturer can hold one tolerance chain and one delivery date instead of passing responsibility between vendors.

Parameter Window

• Available Materials: stainless steel 304/316L, nickel 200, copper C110, titanium Gr2
• Material Thickness Range: 0.03–1.20 mm
• Tolerance: ±0.05 mm on outline and hole position; about ±8% on aperture size
• Minimum Feature: 0.05 mm aperture on 0.03 mm foil, 0.04 mm ligament, open area 15–72%
• Surface Options: electropolishing, passivation, nickel plating, stress-relief annealing, support-ring assembly
• Compliance: ISO 9001 process control, RoHS/REACH material traceability

Manufacturing Process / Workflow (8 Steps)

1. Order & Engineering Review — Check aperture, open area and ligament against stock thickness, flag patterns that cannot be etched cleanly, and issue a process route with the quotation.
2. Incoming Material & Certification — Verify mill certificate, thickness, width, camber and hardness, and record the heat number against the job so the lot stays traceable.
3. Film Generation & Nesting — Build the artwork from the DXF, step and repeat the pattern, and place a test coupon on the same sheet as the production parts.
4. Cleaning & Lamination — Degrease and hot-roll dry film resist, keeping the coating uniform across a large hole field so aperture size does not drift edge to edge.
5. Exposure — Expose through high-resolution film registered to the sheet datum, with exposure energy logged for the lot.
6. Development — Wash out unexposed resist, inspect for incomplete openings, and repair pinholes before the sheet reaches the etchant.
7. Etching — Run conveyor spray etching with chemistry matched to the alloy; endpoint is confirmed on the coupon and by optical aperture measurement, not by time alone.
8. Finishing, Inspection & Packing — Electropolish or passivate, measure aperture, open area, flatness and rim width, then interleave and pack with the inspection record.

Core Advantages

1. No trading markup: the quotation comes from the plant that etches the part, so there is no intermediary layer between drawing and shipment.
2. Engineering review before price: patterns with an impossible aspect ratio or a ligament that will break are caught at quotation, not after the first panel is scrapped.
3. In-house capacity: multiple spray lines and three-shift operation keep scheduled releases on time, including repeat orders that arrive with short notice.
4. Material traceability: mill certificates and heat numbers are filed per lot, which matters for filters used in fuel, hydraulic and medical circuits.
5. One finishing chain: electropolishing, passivation and plating are done in the same plant, so surface finish and aperture are not re-worked by a second supplier.
6. Panel-level consistency: all screens on a panel etch together, so aperture and open area stay within a narrow band; a filter screen etching manufacturer can therefore release a lot against one coupon.

Typical Applications

• Hydraulic and lube-oil filter discs: 304 stainless discs with 0.10–0.30 mm apertures, stacked in a housing with a solid sealing rim.
• Fuel filter screens: fine nickel or stainless mesh inserts that must stay clean under vibration and pressure cycling.
• Polymer melt filter packs: 316L screens with tapered holes that resist clogging and can be back-flushed in place.
• Water treatment discs: large-format etched discs with graded aperture zones for pre-filtration stages.
• Air intake and breather screens: copper or stainless screens that combine airflow with insect and dust exclusion.
• Appliance filter meshes: dishwasher and laundry pump filters with smooth hole walls that release debris when rinsed.

Design Notes & Process Considerations

1. Aspect ratio: keep aperture at 0.8× stock thickness or more for a clean through-hole; tighter ratios need a thinner foil or a different process.
2. Open area versus ligament: state both, since a 70% open area on 0.05 mm foil leaves a ligament that will not survive handling.
3. Hole taper: say which face meets the dirty flow; a taper that opens toward the inlet spreads pressure and slows blinding.
4. Support structure: a coarse support layer or a rolled rim lets a thin screen take differential pressure without a backing plate.
5. Sealing rim: leave at least 3 mm of solid metal at the gasket line, and specify flatness per 100 mm where the screen clamps into a housing.
6. Drawing package: supply DXF, aperture table, open-area target and flow direction; a filter screen etching manufacturer can then quote one route instead of three options.
