Metal mesh discs is an industrial filter component made of stainless steel, aluminum foil and other metal materials as the base material through weaving, stamping, sintering or wave-shaped lamination. It has the characteristics of high temperature resistance, corrosion resistance, high strength and easy cleaning. It is widely used in petrochemical, air purification, food processing, machinery manufacturing and other fields.
1. Material and classification
Classification by material
Stainless steel filter mesh: Made of stainless steel wire mesh as raw material, it is made through weaving, stamping or sintering process. It has excellent corrosion resistance and mechanical strength and is suitable for strong acid, strong alkali or high temperature environment.
Aluminum foil filter mesh: It uses multi-layer expanded aluminum foil mesh to form a wavy structure through rolling. The filtration efficiency is improved by cross-lamination. It has the characteristics of large ventilation volume, low initial resistance and strong fire resistance.
Other metal mesh: including copper mesh, mat mesh, galvanized square mesh, metal plate mesh, etc., and the material can be selected according to different needs.
Classification by process
Woven type: The metal wire is woven into a mesh structure through a loom, and then cut, stamped and other processes are made. The pore size is uniform and the air permeability is good.
Stamping type: Use a punch to punch regular holes on the metal plate to form a plate-shaped filter structure with strong ventilation and low cost.
Sintering type: Multi-layer metal wire mesh is sintered at high temperature to form a porous structure with high strength and good rigidity. It is suitable for high temperature, high pressure or highly corrosive environment.
Wave-shaped overlapping type: Aluminum foil mesh or stainless steel mesh is used as the base material, and it is rolled into a wavy shape. Multiple layers are cross-overlapped to improve the filtration efficiency by changing the direction of the fluid.
2. Characteristics and advantages
Structural characteristics
Multi-layer wavy design: Aluminum foil or stainless steel mesh is rolled into a wavy shape, and multiple layers are cross-overlapped, so that the fluid changes direction many times when passing through, significantly improving the particle capture efficiency.
Density gradient arrangement: The mesh is arranged from coarse to fine, the dust holding capacity is increased by about 40%, and the initial resistance is reduced by 15%-20%.
High temperature and corrosion resistance: The metal material ensures corrosion resistance and mechanical strength, and the service life can reach 2-3 times that of conventional filters.
Strong fire resistance: It has passed the GB/T 5169 standard certification and has excellent fire retardant properties.
Functional advantages
High-efficiency filtration: The multi-layer structure significantly improves the particle capture efficiency and is suitable for precision filtration scenarios.
Strong durability: The metal material is wear-resistant and aging-resistant, and can operate stably for a long time.
Easy to clean and maintain: The plate structure is lightweight, supports user-independent replacement, and has low operating costs.
Flexible customization: Supports non-standard size customization, and the outer frame can be selected as a galvanized frame, aluminum alloy frame, etc. to meet diverse needs.
3. Application scenarios
Industrial filtration
Petrochemical: Used for separation, purification and concentration of gas or liquid, such as distillation, absorption, evaporation and other processes.
Food processing: Filter impurities in liquid or gas to ensure product purity.

Electronic technology: filter clean workshop air to ensure dust-free production environment.
Medical and health: used for ventilation filtration in the biological products, food and beverage industries, in line with hygiene standards.
5. Manufacturing process
Weaving process: stainless steel wire is woven into a mesh structure through a loom, and then heat treated to enhance strength and hardness.
Punching process: use a punch to punch regular holes on the metal plate to form a plate-like filter structure.
Sintering process: multi-layer metal wire mesh is sintered at high temperature to form a porous structure to improve strength and corrosion resistance.
Wave-shaped overlapping process: aluminum foil or stainless steel mesh is rolled to form a wave shape, and multiple layers are cross-laminated and fixed to the frame.
Surface treatment: electroplating, painting or spraying the metal mesh to improve corrosion resistance and aesthetics.
