Precision Etched Filter Mesh, Micro Hole Metal Filter for Medical Devices

Precision Etched Filter Mesh, Micro Hole Metal Filter for Medical Devices

Filter Meshes Overview

Precision etched filter mesh is a thin metal filtration component manufactured by photochemical etching. Unlike conventional woven wire mesh, the filter openings are chemically etched directly into the metal sheet, allowing precise control of aperture size, shape, pitch and pattern.

Xinhaisen's Precision Etched Filter Mesh is manufactured using advanced photo chemical etching technology. It offers superior accuracy, consistency, and design flexibility compared to traditional woven or punched meshes. Ideal for applications requiring precise filtration, shielding, diffusion, or fluid control, our meshes are used in critical industries from medical devices to aerospace.

What is Etching?
Metal etching is a precise, subtractive manufacturing process that uses controlled chemistry to selectively remove material from metal sheets. It produces clean, burr-free parts with complex geometries without heat or mechanical stress, ideal for delicate and high-tolerance parts.

Filter Mesh Features

• Precise & Consistent Apertures: Every opening is identical in size and shape, ensuring predictable and reliable filtration performance.

• Burr-Free & Smooth Surfaces: No loose wires or debris; smooth edges prevent particle trapping and facilitate easy cleaning.

• High Open Area & Strength: Optimized designs provide maximum flow with minimal pressure drop while maintaining structural rigidity.

• Design Flexibility: Any aperture shape (round, square, slot, custom) and pattern layout are easily achievable.

• Material Versatility: Manufactured from stainless steel, copper, titanium, nickel alloys, etc., to suit various chemical and temperature environments.

  • Precision micro-hole and fine-aperture structures
  • Custom aperture size, shape and pitch
  • High dimensional consistency
  • Burr-free etched openings
  • No mechanical cutting force during photochemical etching
  • Suitable for thin metal filtration components
  • Complex patterns can be produced without conventional tooling
  • Custom metal thickness and material options
  • Prototype and mass production available

FAQ

Q1: What is the difference between etched mesh and woven wire mesh?
A: Woven mesh is made by interlacing wires, which can shift under pressure. Etched mesh is created from a solid metal sheet, offering absolute hole position stability, higher flatness, and no risk of wire unraveling. It is ideal for applications requiring rigid, high-precision filtration.

Q2: What is the smallest hole size you can achieve?
A: We can manufacture holes as small as 0.03mm (30 microns) in diameter, depending on the material thickness.

Q3: Can you produce custom shapes (not just round holes)?
A: Yes. We can produce any 2D pattern, including square holes, hexagonal holes, slots, and complex custom logos or designs, without the need for expensive hard tooling.

Q4: Does the etching process leave sharp edges?
A: No. Unlike stamping or machining, our chemical etching process produces a smooth surface with minimal burrs. We can further optimize the process to ensure safe handling and precise flow rates.

Q5: What is your MOQ (Minimum Order Quantity)?
A: We offer low MOQs. We are happy to support small-scale prototyping as well as mass production orders.

Q6: How do you ensure the uniformity of the holes?
A: We utilize high-precision phototools and controlled etching parameters to achieve a uniformity tolerance of ±0.01mm across the entire sheet.

Custom Filter Mesh

The filter opening does not have to be a conventional round hole. Depending on the application, the opening can be designed as round, square, rectangular, slot-shaped or other customized geometries.

Customers can provide CAD drawings, PDF drawings, samples or technical specifications. The filter mesh can then be customized according to material, thickness, aperture, pitch, open area and overall dimensions.
