1. Product Classification: Meet Diverse Industrial Needs

Metal fiber felt and metal fiber cloth are classified according to material, production process and application scenarios, covering a full range of products to adapt to different working conditions. The detailed classification is as follows:

1.1 Classification by Material

The material of metal fiber products directly determines their high-temperature resistance, corrosion resistance and service life, and the main materials we provide include:

• Stainless Steel Fiber Felt/Cloth: The most widely used type, mainly including 316L and 310S stainless steel. 316L stainless steel fiber products have excellent corrosion resistance and temperature resistance up to 650℃, suitable for medium-temperature scenarios; 310S stainless steel fiber products have enhanced high-temperature resistance, with long-term service temperature up to 800℃, which is the core material for high-temperature working conditions such as automotive glass heating zones.

• FeCrAl Fiber Felt/Cloth: With outstanding high-temperature oxidation resistance, the long-term service temperature can reach 900-1000℃, and the maximum temperature can reach 1100℃. It is specially designed for ultra-high temperature scenarios such as automotive glass bending and tempering furnaces, photovoltaic glass production and high-temperature filtration, and has a longer service life in harsh environments.

• Special Alloy Fiber Felt/Cloth: Including nickel-based alloy, titanium, copper and other materials. Nickel-based alloy fiber products have strong corrosion resistance, suitable for petrochemical and marine fields; titanium fiber products have excellent biocompatibility and corrosion resistance, used in new energy and biomedical fields; copper fiber products have good electrical and thermal conductivity, suitable for electromagnetic shielding and electronic components.

1.2 Classification by Production Process

Different production processes determine the structure, hardness and functional characteristics of metal fiber products, mainly divided into two categories:

• Needled Metal Fiber Felt: Formed by physical needle-punching entanglement process, it is soft, fluffy and elastic, with good buffering performance. It is mainly used for roller cover wrapping, soft contact protection and thermal insulation in automotive glass production. The surface is delicate and free of burrs, which can effectively avoid scratching high-temperature glass blanks. It is available in rolls or cut sheets, and can be customized according to size.

• Sintered Metal Fiber Felt: Formed by high-temperature sintering and welding in a vacuum furnace, the fiber contact points are melted and bonded to form a stable three-dimensional porous structure. It is stiff and has high strength, pressure resistance and high filtration precision. It is mainly used for high-temperature fluid filtration, gas purification and catalyst carriers in industrial fields. It can be cleaned and reused, reducing production costs.

• Metal Fiber Cloth: Divided into woven and knitted types, with high strength and uniform structure. Woven metal fiber cloth is wear-resistant and suitable for industrial protection and electromagnetic shielding; knitted metal fiber cloth is flexible and conformable, especially suitable for mold covering in automotive glass bending, ensuring the optical quality of glass products.

1.3 Classification by Application Scenarios

Combined with the needs of different industries, our products are divided into targeted series, focusing on the automotive glass industry, and covering multiple fields:

• Automotive Glass Special Series: Including metal fiber roller covers, needled felt for glass forming, high-temperature resistant cloth for heating zones, etc., which are specially used in heating, bending, tempering, annealing and conveying links of automotive glass production, realizing soft contact, scratch prevention and high-temperature protection, and meeting the production requirements of Fuyao, Asahi Glass and other mainstream automotive glass manufacturers.

• High-Temperature Filtration Series: Including sintered metal fiber felt, filtration elements (filter cartridges, filter discs), etc., used in high-temperature flue gas filtration in power plants, waste incineration, petrochemical fluid purification and other scenarios, with high filtration efficiency and stable performance.

• Thermal Insulation and Sealing Series: Including soft needled felt, special-shaped gaskets, etc., used for thermal insulation and sealing of high-temperature equipment, pipelines and instruments, with good thermal insulation performance and high-temperature resistance.

2. Core Features: Outstanding Performance, Stable and Reliable

Our metal fiber felt and metal fiber cloth integrate multiple advantages, which are better than traditional industrial materials, and can adapt to various harsh working conditions. The core features are as follows:

• Excellent High-Temperature Resistance: Different materials have different temperature resistance ranges (316L: ≤650℃, 310S: ≤800℃, FeCrAl: 900-1100℃), which can withstand repeated heating and cooling without embrittlement or damage, and are suitable for long-term use in high-temperature environments such as glass tempering furnaces and industrial combustion equipment.

• Soft Contact and Scratch Prevention: Needled metal fiber felt and knitted metal fiber cloth are soft and delicate, which can avoid direct contact between hard equipment and high-temperature glass blanks, effectively preventing scratches, indentations and edge chipping of glass products, and improving the qualification rate of finished products. This feature is particularly critical in automotive glass bending and forming links.

• High Strength and Durability: Sintered metal fiber felt has high rigidity and tensile strength, which can bear high pressure and impact without deformation; needled felt is treated with anti-shedding technology, which does not shed silk or slag, and has a long service life, reducing the frequency of product replacement and maintenance costs.

• Corrosion and Wear Resistance: Stainless steel, FeCrAl and special alloy materials have excellent corrosion resistance, which can resist the erosion of acids, alkalis and organic solvents; the surface of the product is treated with wear resistance, which can adapt to the continuous friction in the conveying link and ensure stable performance during long-term operation.

• Customizable and Versatile: All products can be customized according to the customer's requirements for thickness, density, size, shape and material, and can be processed into roller covers, filter elements, special-shaped gaskets and other finished products, adapting to the personalized needs of different industries and production lines. The porosity can be controlled between 60%-90%, and the filtration precision can be adjusted from 0.1-300μm.

• Eco-Friendly and Reusable: The product is made of high-quality metal fibers, which is non-toxic, harmless and pollution-free; sintered metal fiber felt can be cleaned and reused, which is in line with the concept of green and energy-saving production, and reduces the waste of resources.
