Formed Etched Cup Filter is used for filtering at valve, pump and injector inlets with tiny cups deep-drawn from etched metal foil, combining precise etched holes with a cup shape that adds filter area and press-fits into a bore. Photo-chemical machining to drawing (ISO 2768-f) is the reference cited for it on drawings, datasheets and purchase orders.
What Photo-chemical machining to drawing (ISO 2768-f) Means for Formed Etched Cup Filter
The dimensions in the table below are supplied to suit Photo-chemical machining to drawing (ISO 2768-f). Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Formed Etched Cup Filter Dimensions
| Size | Top diameter (mm) | Depth (mm) | Hole diameter (mm) | Thickness (mm) | Use |
|---|---|---|---|---|---|
| Cup 6 | 6 | 4 | 0.08 | 0.05 | Injector inlet |
| Cup 10 | 10 | 8 | 0.10 | 0.08 | Pump inlet |
| Cup 20 | 20 | 15 | 0.15 | 0.10 | Appliance valve |
Specifying Formed Etched Cup Filter Beyond the Standard
- Size: 6–20 mm diameter cups with depth to suit the bore.
- Holes: 0.08–0.15 mm etched holes, laid out so forming does not distort them.
- Material: SS304 or SS316L foil, 0.05–0.1 mm.
When Formed Etched Cup Filter Is Not the Right Choice
Not for high dirt loads; a larger cartridge or basket gives more area.
