Laser-Drilled Micro-Hole Filter Disc in 316L Stainless Steel (AISI 316L (1.4404)) is used for controlling flow and holding back fine particles with discs laser-drilled with micron-sized holes in exact positions — for restrictors, nozzles and medical devices. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Where 316L Stainless Steel Laser-Drilled Micro-Hole Filter Disc Is Used
- Medical devices: drug-delivery restrictors, inhaler and IV flow control discs.
- Aerospace & space: propulsion and gas metering orifices.
- Instruments & sensors: pressure snubbers and calibrated leaks.
- Atomization: spray and mist nozzle plates.
Ordering Laser-Drilled Micro-Hole Filter Disc in 316L Stainless Steel
- Hole diameter & tolerance: 20–100 µm holes held to about ±3–5 µm.
- Hole count & layout: From a single orifice to thousands, in any pattern.
- Thickness: 0.1–0.5 mm; thicker discs need tapered or stepped drilling.
Mistakes to Avoid with Laser-Drilled Micro-Hole Filter Disc
- Specifying a hole tolerance tighter than the flow requirement actually needs.
- Skipping recast removal, which partly blocks small holes.
