Deep-drawn mesh filter cups
Deep-drawn stainless mesh cups with continuous walls, defined bottom radii and plain, rolled or flanged rims.
Product detailsDrawing-based manufacturing
Filter cups and domed screens
Formed metal mesh cups, flanged inserts and domed screens protect compact fluid passages. We match the finished mouth, seating rim and filtration surface to the port geometry, combining the selected mesh with a support layer where the assembly carries a directional flow load.

Deep cups, seating flanges and domed screens
What we need to form a cup
A formed component is quoted from a drawing — the shape, the mesh and the edge construction are decided together.
Diameter, depth and radii
Defines forming severity. Dimension the mating seat as well as the free-standing part.
Mesh, wire diameter and material
Affects formability and final opening. Keep weave, wire diameter and starting aperture together.
Rim and joining details
Controls fit and bypass. Show the clamped, pressed or welded connection in section.
Flow and support direction
Guides layer arrangement. Mark the open end and the supported side with flow arrows.
Finished-part acceptance
Defines inspection after forming. Locate measurements on the mouth, wall, radius and crown.
Mesh media
Specify alloy and weave, then pair mesh count or clear aperture with wire diameter. Woven configurations cover 20–500 mesh, expressed as openings per inch; identify the exact combination for each formed variant.
Define the functional surfaces of a formed screen
| Surface | Drawing input | Assembly function | Finished check |
|---|---|---|---|
| Mouth and rim | Seat diameter, rim width and edge | Locate and retain the cup | Fit, flatness and contained wire ends |
| Wall and radius | Depth, diameter and transition radius | Expose mesh within the cavity | Opening condition and profile |
| Crown or bottom | Height and mating clearance | Complete the filtering boundary | Broken wires and contact clearance |
| Support layer | Layer position and edge fastening | Carry directional flow loading | Layer alignment and secure attachment |
Construction
How a formed component is made
- Cup depthCup depth determines exposed surface and forming geometry. Blank outline, wall height and transition radius are developed together for the specified weave.
- Dome clearanceThe dome positions the screening surface away from the inlet and adjacent parts. Mesh layers and backing carry the specified flow loads through the retained rim.
- Rim conditionA flat, secured rim locates the part and contains cut wire ends. Its seating width, flatness and attachment create the perimeter flow boundary.
- FormingInspect the finished sidewall, transition radius and crown as separate forming zones. Check openings, wire continuity and folds against the specified finished-part requirements.
- Installed rim and supportThe rim provides a positioning or clamping surface; the exposed wall and crown provide filtration. Locate the support layer against the flow load and define how the layers terminate at the rim.

Read the shape from the installed seat
A cup is defined by its mouth, wall, bottom or crown, transition radius and rim. A shallow dome provides a curved surface near the port; a deep cup extends the filtering wall into the available cavity. The seat drawing identifies the space that each surface occupies.
An integral flange locates the part against a shoulder. A folded or rimmed edge contains cut wires, while a separate ring provides a controlled clamping or joining surface. State which surface locates, which surface seals and which portion remains exposed to flow.
Inspect the formed mesh by surface zone
Forming moves wires around the tool profile. The wall, transition radius and crown are inspected as separate zones, with opening condition and broken-wire checks tied to the finished geometry. The starting weave and aperture remain part of the material identification.
A replacement specification includes the open-end orientation, supporting layers, rim fastening and handling method. Protective packing keeps shallow domes and thin rims from being flattened before assembly, while batch labels connect the formed part to its selected mesh.
Filter cups and domed screens
Applications
Formed mesh components go where a flat screen will not fit or will not give enough area.
Nozzle inlets
Domes keep the screen surface clear of the inlet opening.
Valve ports
Flanged cups locate in small removable seats.
Instruments
Formed inserts capture debris upstream of narrow passages.
Vent and breather ports
Mesh caps that let air pass while stopping particulate, protecting tanks, gearboxes and enclosures.
Compact instrument protection
Small formed screens ahead of sensors and analysers where the envelope allows only a cup of a few millimetres.
Documented product examples
Deep-drawn mesh filter cups
Deep-drawn mesh cups add filtering area inside a compact housing while keeping a one-piece formed wall. The finished rim, depth and formed opening must be checked after drawing.
Domed mesh screens
Domed wire-mesh screens create clearance above a flat seat while retaining a defined mesh surface. The dome height, base diameter and edge finish determine installed fit.
Inspect after forming
Check the finished shape and opening together.
Profile
Measure depth, crown radius and rim diameter.
Mesh distortion
Inspect stretched openings, broken wires and folds.
Seating
Check rim flatness, loose wire ends and insertion fit.
Layer retention
Check the attachment between the filter layer, support and rim. Edges remain contained during insertion and withdrawal, and the layers retain their specified position.

Questions before ordering
Does forming change the aperture?
It can. Wires move as cloth is drawn over a tool. Inspect the finished wall and crown rather than assuming the starting aperture is unchanged.
When is a dome preferable to a flat disc?
Where additional clearance or exposed area is needed in a shallow seat. Check contact with the mating part and allowable deformation.
How do I choose the rim construction?
An integral flange locates the cup in a counterbore; a folded edge contains cut wires; a separate ring provides a stronger seating or joining surface. Specify flange OD, seat width, flatness and whether the rim seals or only retains the cup.
How is a replacement cup measured?
Measure mouth diameter, seating diameter, depth, flange width and the transition radius from a consistent datum. Include the mating recess, insertion direction and nearby clearance so that the new cup matches its installed seat.
What does a support layer contribute?
A layer of coarser mesh supports the fine filtering mesh in the specified flow direction. Its position, formed profile and rim attachment are defined with the filtering layer, preserving the exposed area and installation envelope.
