Diffusion Bonded / Sintered Metal Filter

SinterPore™ Sintered Metal Filter

Dorstener Wire Tech offers a full line of diffusion bonded sintered wire cloth and sintered wire mesh sintered metal filter products under the brand SinterPore™.

Sintered Metal Mesh is a wire filtering cloth made by pressing multi-layer stainless steel woven wire cloth, then sintered together in a vacuum furnace. This kind of filtering cloth is much better than common metal woven wire mesh with good strength, hardness and good positioning of opening. Its comprehensive property is superior to sintered metal powder and porcelain.

Sheet Sintering or true diffusion bonding, is a process that utilizes time, temperature, pressure and atmosphere to realign and permanently bond the molecular elements of the alloy where they intersect or touch each other. This product is available in single or multiple layer construction. The process produces a stable, secure mesh that can be used for filtering in high pressure applications.

Coil Sintering is a process that utilizes time, temperature, and atmosphere to secure or stick intersections of the wire mesh. The mesh can be calandered prior to heat treating to aid in bonding. The process produces a stable, secure mesh that is ideal for deep drawing and or reducing the risk of loose wire’s loose. This product is only available in single layer options.

SinterPore™ Sintered Metal Mesh provides many additional benefits when compared to traditional wire cloth.
  • Diffusion bonded wire cloth can be fabricated in single or multiple layers. Multiple layer assemblies provide enhanced mechanical properties for filters and harsh environment applications.
  • Sintered wire mesh is stable, making it ideal for mesh with a high percentage of open area or that requires a secure pore size.
  • SinterPore™ sintered mesh is easy to fabricate and produces a stable, strong product. It can be constructed as a depth filter media, providing excellent filtration properties. It is an excellent material to use for products that require controlled permeability.
  • Sintered wire mesh can be cleaned and re-used for many applications.
  • Diffusion bonding locks and secures all wire in the mesh, eliminating loose wires and increasing the stability of the cloth. It can be used for small parts and special shapes without losing shape or loose wires. Traditional wire cloth can become loose and ineffective over time.

SinterPore™ sintered metal filter wire mesh is available in a wide range of micron ratings, mechanical properties and alloys. The standard product is available in 24” x 48” sheets produced from 316LSS stainless steel. Many other alloys are and sizes are available up to 48” x 55”.

Definition of Sintered or Diffusion Bonded Wire Mesh:

Stainless Steel Sintered Wire Mesh is a filtering cloth made by pressing multi-layer woven wire cloth, then sintered together in a vacuum furnace. This kind of filtering cloth is much better than common metal woven wire mesh with good strength, hardness and good positioning of opening. Its comprehensive property is superior to sintered metal powder and porcelain. The major characteristics are: excellent strength, no inner support is required for making filter elements, no material, easily repeated cleaning, long lifespan and good anti-corrosion.

What Are Sintered Mesh Laminates?

Fine woven wire filter mesh provides micron-rated pore size but it is too thin and can be damaged. The best solution is to laminate the fine mesh to a coarser mesh supportive layer to provide increased strength and thickness. The common sintered wire mesh laminates are 5-layer or 6-layer, which is extensively used in filtration.

Diffusion Bonded Filter Elements

DWT produces a wide range of filter elements utilizing sintered wire cloth. Sintered Wire Mesh elements have many advantages over standard filter elements.
