Photochemical Machining for Metal Filtration & Flow Control

From metal filtration media and mass flow controllers for liquids and gases to ultra-fine meshes and precision grids, performance depends on geometry measured in microns—not compromises imposed by tooling. Photo chemical machining (PCM) enables engineers and designers to produce high-precision metal components with complex apertures, thin cross-sections, and burr-free edges that directly enhance flow control, filtration efficiency, and repeatability.

At Conard, we partner with engineers who need function-first design freedom, tight tolerances, and scalable production—without distortion, tool wear, or secondary finishing. PCM delivers exactly that.

  • Holes as small as .004″ (see conditions)
  • Minimum hole size >= to 110% of metal thickness
  • Minimum ligature between holes >= to metal thickness

Photochemical etching is an ideal process for perforated metal products, such as:
Filtration
  • Grids
  • Screens
  • Meshes
  • Filters
  • Separators
  • Microfilters
  • Grilles
  • Lighting diffusers and more

Unlike mechanical perforating methods such as punching, stamping or laser cutting, photochemical machining of metal leaves the material free of burrs and induced mechanical or thermal stress or deformation.
