Besides any custom designs, there are several main standard types of wire mesh laminates:

5-Layer Sintered Wire Mesh

Sintering is a process that improves the characteristics of woven wire mesh by bonding the contact points of all the wires together to form a mesh whose wires are securely fused in place. This is achieved through a combination of heat and pressure, and the result is a single layer sintered wire mesh.

 

Sintered Wire Mesh with Perforated Metal

This type of sintered wire mesh laminate is made by taking several layers of woven wire mesh and sintering them to a layer of perforated metal. The woven wire mesh layers consist of a filter layer, a protective layer, and possibly a buffer layer between the fine mesh layer and the perforated plate. The perforated plate is then added as the base and the entire structure is sintered together to form a very strong yet tractable plate.

 

Sintered Square Weave Mesh

This type of sintered wire mesh laminate is made by sintering multiple layers of plain weave square woven wire mesh together. Because of the large open area percentages of the square woven wire mesh layers, this type of sintered wire mesh laminate has good permeability characteristics and low resistance to flow. It can be designed with any number and combination of square plain weave wire mesh layers to achieve particular flow and filtration characteristics.

 

Sintered Dutch Weave Mesh

This type of sintered wire mesh laminate is made by sintering 2 to 3 layers of plain Dutch woven wire mesh together. This type of stainless steel sintered wire mesh laminate has evenly spaced openings and good permeability to flow. It also has very good mechanical strength due to the heavy dutch woven wire mesh layers.

 

Our sintered wire mesh products are manufactured in sheets in standard sizes of 2’x4′, or 4’x4′. These sintered wire mesh laminates can be custom made to meet a thickness requirement, a filtration rating, and/or a certain number of layers. If you have your own custom design, we can sinter just about any combination of wire mesh layers together to form a sintered mesh part.

These can be shipped as flat sheets, or we can cut a variety of custom sized discs or donuts, or cut different sized square and rectangular sheets. These sintered wire mesh laminates can also be rolled into tubes to form cylindrical sintered filters. We specialize in taking your part from initial design to the finished product, from sourcing the wire mesh to sintering the multiple layers to forming and fabricating into the final assembly.

What is Sintering?

Sintering is a process that improves the characteristics of woven wire mesh by bonding the contact points of all the wires together to form a mesh whose wires are securely fused in place. This is achieved through a combination of heat and pressure, and the result is a single layer sintered wire mesh.

Sintered Metal Characteristics

  • High mechanical strength, with the ability to maintain a steady filter rating under high pressure.
  • Easy to clean with a variety of filter cleaning techniques and reuse.
  • Heat and corrosion resistant.
  • Easy to fabricate, weld, punch, shear, or otherwise form into various parts.
  • Wide range of filter ratings.

Can you sinter together multiple layers of wire mesh?

Yes, a more common application of the sintering process involves laminating multiple layers of woven wire mesh together to form a sintered mesh part that compared to a single layer of wire mesh has increased mechanical strength, greater preservation of filter rating under pressure, is easier to clean, and has better structural integrity. A multiple layer sintered wire mesh part can maintain the filtration rating of its finest mesh layer, while also maintaining the mechanical strength of its coarser support layers.
