Porous Metal Filter’s SinterPore® laminate can be fabricated much like sheet metal, in a number of shapes and sizes from simple discs to complex conical assemblies. PMF has a fully functional fabrication shop in house with state of the art equipment and an experienced and knowledgeable staff, allowing us to service all of your porous media needs. PMF manufactures products to the highest current industry standard, certified to meet ISO 9001.


Sintering:

Laminating capability of 1 to 1500 layers. Standard sheets sizes are 18”x48”, 20”x48”, & 24”x48”. Maximum panel size with no weld is 40”x48”. Maximum width is 120” with welds, and the lengths are unlimited.

Testing:

PMF has a full range of testing capabilities including: Tensile, strauss, Alloy, Permeability, and more.

Shearing/Slitting:

Available up to 500’ in length and up to 60” wide +/- 0.020”


Laser And Water Jet Cutting:

The material can be cut like metal plate to make small runs in a multitude of possible shapes (both 2D and 3D conical structures)

Punching:

Extensive range of punching capabilities, with a large inventory of dies in many shapes and sizes. Custom shapes and sizes available upon request.

Forming:

Capability to form pleated elements, cones, and simple cylinders with diameters ranging from .375” to 20”, and lengths available up to 48” in a single tube, longer lengths available with additional weld joints.


Welding:

Like metal plates, porous metal materials can be welded with resistance, TIG, plasma, and electron-beam welders.

Assembling:

The fittings, end caps and cages must be seamlessly assembled to the filter without any pinholes or gaps between the filter media and the other fittings that would compromise the filtration integrity. All parts are welded together to ensure permanent bonds that will not be compromised by chemical attack and thermal or pressure cycling. Production lot tests, such as bubble point or airflow, will ensure that the filter is properly constructed.

Surface Finishing:

Removes iron from the surface and enhances de chromium/nickel content providing the most superior form of passivation for stainless steel. This process provides a clean and smooth surface that is easier to sterilize. It also improves the surface finish by leveling micro-peaks and valleys.
