Laser-slotted filter tubes
Metal tube with longitudinal or circumferential laser-defined slots.
Product detailsDrawing-based manufacturing
Laser-perforated and slotted screens
Drawing-defined slotted sheets, cylinders and discs where hole placement or profile makes a standard punched pattern unsuitable. Aperture, thickness and edge quality must be assessed together for the selected cutting route.

Construction
Define the opening on the finished part
- Pattern placementSlots can be positioned around mounting features with solid weld bands instead of an uninterrupted repeated pattern.
- Cut faceEntry and exit openings can differ. Define the controlling surface and acceptance limits for taper, burrs, dross and oxide.
- Specialist processesFine apertures may require a specialist media-production route. Component fabrication does not imply ownership of every micro-cutting process.

| Construction | Application and fit | Confirm first | Find a product |
|---|---|---|---|
| Flat laser-cut screens | The finished screen remains flat and pattern location is critical. | CAD revision, material, thickness, pattern, outline and flatness. | Filter matching products |
| Laser-slotted cylinders | The patterned screen must become a cylindrical component. | Developed blank, diameter, seam, slot orientation and end condition. | Filter matching products |
| Framed laser-cut panels | The thin patterned screen needs a rigid installation interface. | Frame, clear opening, pattern datum, joint, fixing and flatness. | Filter matching products |

Applications
Laser patterns address geometry-specific component requirements.
Cylinders
Slotted surfaces with end bands and controlled seams.
Panels
Apertures arranged around stiffeners and fixings.
Screen inserts
Discs and profiles unsuited to standard punch patterns.
Aperture quality includes both faces
Measure on the face defined by the drawing.
01OpeningCheck slot width, pitch and taper.
02Cut edgeInspect burrs, dross and local heat effects.
03After rollingCheck changes to aperture and cylinder roundness.

Questions before ordering
Can laser slots directly replace wedge wire?
Not automatically. Sheet thickness, aperture taper and support geometry differ from profile wire. Compare cleaning, clogging and pressure loss as well as slot width.
Can any opening smaller than sheet thickness be produced?
No universal ratio applies. Alloy, thickness, process, pattern density and acceptable taper must be considered together.
What drawing files are useful for a laser-cut screen?
A DXF or other agreed CAD file should be accompanied by material, thickness, critical dimensions, tolerance, edge finish and a marked flow or installation direction.
