Sintering Makes Wire Mesh with Finer Filtration Accuracy & Higher Mechanical Strength

Sintered wire meshes are produced through a series of technical processes including pre-calendering, laminating and vacuum sintering. The materials are heated in a vacuum environment until they almost reach their melting point. When heated, the material becomes more compact, resulting in a new material with completely different properties, with a more uniform aperture size and stable apertures compared to the previous one.

Sintering Production Advantages:

• Improve original materials performance and structure
• Make the material composition more stable
• No impurities and no contamination of original materials

Sintering Production

Cutting

Cut the wire mesh to the desired size by laser cutting or EDM cutting process depending on the requirements.

step 1

Pre-Calendering

Pre-Calender the wire mesh evenly so that each layer makes good contact, especially at the intersection of the wire mesh.

step 2

Laminating & Spot Welding

Laminate and spot weld the wire mesh, give it a relatively stable structure and a better performance.

step 3

Sintering

Then, put one or more layers rolled wire mesh in a high-temperature furnace under mechanical pressure. The furnace is filled with a specific inert gas. When the temperature achieves set sintering degree, sintering occurs and a sintered wire mesh is formed.

step 4

Controlled Cooling

Cool wire mesh by controlling the temperature to give it good stiffness. By sintering multiple layers of different wire meshes, it is possible to customize sintered wire meshes with specific thicknesses, diameters, apertures, precision and mechanical strength.

step 5

Calendering

Calender the cooled wire mesh to give the material a more uniform thickness.

step 6

Flattening & Stretching

Wire mesh has memory in the material after processing. Flattening and stretching it to stabilize the mesh and improve its overall quality.

step 7

Cleaning & Drying

After processing, we can clean dirt and oil off the mesh and package it to prevent contamination during shipping and storage, ensuring that the wire mesh product is clean for use in production.

Sintering Mesh Advantages

Sintered mesh has a uniform and ideal filtration structure with interlocking apertures in each layer. It overcomes the shortcomings of low strength, poor stiffness and unstable aperture shape of common metal wire mesh. By reasonably matching and designing the aperture size, permeability and strength characteristics of the material, it has excellent filtration precision, filtration resistance, mechanical strength, wear resistance, heat resistance and processability. Its comprehensive performance is significantly better than other types of filter materials such as metal powder sintered mesh, ceramics and metal mesh.
