In the mining and metallurgy sectors, concentrate dewatering, tailings treatment, and hydrometallurgical leachate filtration are critical steps in the production process. Recently, with the expansion of mining capacity in South America (Brazil), Southeast Asia, and the Middle East, as well as the improvement of water recycling rates in mineral processing, the market demand for high-wear-resistant and high-strength filtration consumables has significantly increased.
Industry experts note that mining working conditions are highly complex; the particle size, temperature, and pH of the slurry directly affect the filtration efficiency and service life of the filter cloth. Currently, an increasing number of mining enterprises prefer to cooperate directly with source filter cloth factories. By providing filter press models and on-site working condition parameters, they can obtain tailored filter cloth (e.g., custom width, sewing structure, and air permeability) to achieve higher filtration capacity and lower consumable replacement frequency.
As global environmental and hazardous waste treatment standards for the chemical industry become increasingly stringent, chemical enterprises face higher filtration requirements in processes such as calcination, crystal slurry pressing, and sludge dewatering. Traditional filter cloth often suffers from short lifespan and easy damage when handling highly corrosive mother liquors and high-temperature materials, driving the growing market demand for high-performance industrial filter cloth.
Industry analysis indicates that woven filter cloth featuring excellent chemical corrosion resistance, high tensile strength, and precise opening rates is becoming the preferred choice for chemical buyers. Furthermore, providing customized filter cloth selection and PTFE membrane treatment based on the characteristics of different materials—such as titanium dioxide, dyes, and inorganic salts—can effectively improve solid-liquid separation efficiency and reduce overall operational costs.
Zhejiang Aiye Filtering Cloth Co., Ltd. has successfully passed the annual review of the ISO9001 Quality Management System, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System. As a National High-Tech Enterprise and a Zhejiang Provincial "Specialized, Refined, Distinctive and Innovative" SME, Aiye always prioritizes product quality and production standards.
In daily production, Aiye implements strict incoming material inspection, in-process quality control, and final product inspection. Each batch of filter cloth undergoes sampling tests for weight, thickness, warp and weft tensile strength, air permeability, and temperature/chemical resistance. The company is equipped with a full set of filter material testing instruments and can provide third-party test reports such as RoHS and REACH upon request, ensuring that products exported to Europe, Southeast Asia, and South America meet local environmental and industrial standards.
Zhejiang Aiye Filtering Cloth Co., Ltd. has recently announced the completion of a new round of production capacity upgrades. Currently, 38 Belgian Picanol looms, along with 24 non-woven production lines and complete post-treatment equipment, are fully operational in the factory. Following this upgrade, the company's monthly capacity for woven filter cloth has reached 400,000 m², with an annual capacity exceeding 4.8 million m², and an annual capacity of 1.98 million dust filter bags.
Picanol looms offer significant advantages in warp and weft density control, fabric surface flatness, and batch-to-batch consistency. Combined with Aiye's comprehensive post-treatment processes—including weaving, needle punching, heat setting, singeing, calendering, and acid/alkali resistant impregnation—the company can provide stable and high-precision industrial filter cloth products for global mining, chemical, and metallurgical customers. Aiye stated that it will continue to invest in advanced equipment to ensure the stable delivery of large and customized orders.
Zhejiang Aiye Filtering Cloth Co., Ltd. has recently completed a customized PP (Polypropylene) filter cloth order for the Indonesian mining market. Addressing the client's challenges with fluctuating pH levels in the slurry and strict requirements for filter cake moisture, Aiye's technical team selected PP filter material with excellent acid and alkali resistance and customized the width and cutting sizes according to their filter press equipment.
From working condition communication, solution design, and sample testing to mass production and customized export packaging, Aiye completed sample approval within 12 days and delivered the bulk order on schedule. With stable quality and professional foreign trade services, the client has established a long-term partnership with Aiye, purchasing approximately 450,000 m² of filter cloth annually. This fully demonstrates global customers' recognition of Aiye's customization and delivery capabilities.
