Woven Wire Mesh VS Sintered Mesh

Both of woven wire mesh and sintered wire mesh play an important role in filtration among a wide range of applications like oil & gas filtration. It is known that sintered wire mesh is a kind of diffusion-bonded woven wire mesh, or that sintered wire mesh is woven wire mesh experienced heat-treating process, which will improve a lot of original properties. Our company has rich experience in manufacturing those meshes and will produce professional advice to help you select the suitable filter mesh. To know better woven wire mesh & sintered mesh, let's start from the concept of woven wire mesh.

• What is woven wire mesh?
  Woven wire mesh is typically woven with wires running in two vertical directions - warp & shute, and are manufactured in rolls. Standard mesh roll size would be 36" or 48" wide × 100 ft long. The wires running the full length are called "warp" wires while those running across the width are called "weft", "fill" or "shute" wires. See the Fig-1, you will find the four frequently-used weave styles. Sometimes depending on our customers' special requirements, bespoke type will be available. Commonly, twilled dutch weave is for finest meshes while plain & dutch weaves for relatively coarse mesh.

• What is sintering or diffusion bonding?
  Sintering or diffusion bonding is a thermal process that fuses tangent metal surfaces without the additional filler metals or bonding agents.

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

• What are the advantages of sintered mesh?
  1. Adds stability & strength.
  2. Back-washed & cleaned.
  3. Stable pore structure.
