Introduce

Knitted wire mesh gasket is a composite gasket made of knitted wire mesh and elastic material. Compared with woven wire mesh gasket, the metal wire of knitted wire mesh gasket is woven by special knitting technology, which has different structural characteristics and performance advantages. It is widely used in industries that require high sealing, strong electromagnetic shielding effect or conductive function, providing excellent sealing, shock absorption and anti-interference performance.

Features:

Electromagnetic shielding: effectively resist external electromagnetic interference (EMI) and radio frequency interference (RFI), protecting the normal operation of sensitive equipment.

Sealing performance: elastomeric materials provide reliable sealing effect to prevent leakage of liquid, gas or particles.

Conductivity: metal wire mesh ensures good conductivity and protects electronic equipment from static damage.

Anti-vibration and shock absorption: effectively reduce the damage of vibration to equipment and extend the service life of equipment.

High temperature and corrosion resistance: using high temperature resistant, stainless steel and other materials, it can work stably and long-term under extreme conditions.

Manufacturing process

1. Selection and treatment of metal wire

First, select suitable metal wire materials. Common materials include stainless steel, copper, beryllium copper, nickel and other metals, which have excellent conductivity, high temperature resistance and corrosion resistance. The diameter, strength, conductivity and other properties of the metal wire need to be determined according to the functional requirements of the final gasket.

Surface treatment: In order to improve the corrosion resistance and durability of the metal wire, the metal wire is usually surface treated (such as nickel plating, chrome plating, passivation, etc.) to ensure its stability in long-term use.

2. Knitting and weaving of metal wire

The metal wire is interwoven into a mesh through a knitting process. Knitting is tighter and more structurally stable than traditional weaving processes, which can enhance the overall strength and durability of the metal wire mesh. The weaving methods of knitted metal wire mesh usually include plain weave and twill weave, etc., and the appropriate weaving method is selected according to the specific application requirements of the product.

Weaving process: On the knitting machine, the metal wire is interwoven into a mesh through the needles and yarn frames of the knitting machine to form a mesh structure of different specifications. Knitted metal wire mesh usually has good tensile strength and tear resistance, and is suitable for environments with high pressure or high temperature.

High temperature pressing: The wire mesh is combined with the elastomer material through high temperature heating and pressure to ensure that the two are firmly bonded to form a composite structure.

Bonding process: You can also use strong glue or special adhesives to connect the wire mesh with the elastomer material to ensure its long-term stability and sealing effect.

3. Vulcanization or curing treatment

For rubber elastomer materials, vulcanization treatment is usually required. The vulcanization process cross-links the molecular chains of the rubber through heating and chemical reactions, enhancing elasticity and high temperature and wear resistance.

Curing: Vulcanization treatment or other curing processes make the elastomer have good sealing, pressure resistance and heat resistance, and improve the comprehensive performance of the gasket.

4. Cutting and forming

Cut the knitted wire mesh gasket that has been combined into the required size and shape. This step usually requires the use of precision cutting tools to ensure that the product size is accurate, the edges are smooth, and it can meet the installation requirements of different equipment.

Precision cutting: Use laser cutting or mold cutting to ensure the cutting quality of each gasket and avoid damage to the wire mesh or elastomer during the cutting process.
