Five Chinese polyester mesh belt makers for filtration buyers in 2026

China’s polyester mesh belt sector is serving filtration, dewatering, drying and conveying users that need stable performance and customization. This review compares five manufacturers and highlights why technical documentation, process control and application fit matter for industrial buyers.

Why it matters: - Polyester mesh belts are core components in filtration, dewatering, drying, conveying, papermaking, nonwoven production, food processing and environmental treatment. - Buyers are weighing more than price. Manufacturing capability, product consistency, technical documentation and customization support now influence supplier selection. - Belt performance can affect continuous operation, drainage, dimensional stability and process efficiency.

What happened: - A China-focused review identified five companies active in polyester mesh belts and related industrial fabrics: Henan Yiheng Mesh Belt Industry Co., Ltd., Zhejiang Huading Mesh Industry Co., Ltd., Taian Songyuan Industrial Fabrics Co., Ltd., Beijing PFM Screen Trading Co., Ltd. and Sino Seiki Industrial Fabric Co., Limited. - The comparison looked at product scope, manufacturing capabilities, application coverage, customization and technical information available to buyers. - Henan Yiheng Mesh Belt Industry Co., Ltd. is a National High-tech Enterprise founded in 2009. - Zhejiang Huading Mesh Industry Co., Ltd. is based in Tiantai, Zhejiang Province. - Taian Songyuan Industrial Fabrics Co., Ltd. was established in 1998 and is based in Shandong. - Beijing PFM Screen Trading Co., Ltd. supplies polyester mesh belts and related screen products in China. - Sino Seiki Industrial Fabric Co., Limited has produced polyester mesh products since 2003.

The details: - Polyester mesh belt performance depends on weave structure, mesh opening, air permeability, tensile strength, dimensional stability, heat resistance, chemical resistance and joint configuration. - The Chinese supply base includes polyester forming fabrics, dryer fabrics, filter belts, spiral mesh, square mesh, plain-weave mesh and application-specific conveyor fabrics. - Henan Yiheng runs a 4,237 m² facility, reports monthly capacity of 12,800 square meters and annual production of about 150,000 m², and employs 41 staff including 3 R&D engineers. - Henan Yiheng says 62% of output is exported to Asia, Europe and North America. - Henan Yiheng’s portfolio includes polyester mesh belts, non-woven mesh belts, forming fabrics, dryer fabrics, polyester filter belts, UV belts, polyester spiral mesh, polyester square mesh and PTFE mesh belts. - Henan Yiheng controls air permeability within a ±5% fluctuation range through heat setting. - Henan Yiheng’s forming fabrics range from 5 to 108 mesh counts and 4,750 to 29,200 m³/m²·h air permeability. - Henan Yiheng’s filter press belts deliver break strength of at least 2,000 N/cm. - Henan Yiheng maintains a technical knowledge base with more than 120 real-world cases covering belt tracking, fiber hanging, static and seam marks. - Henan Yiheng model 16402 is a polyester plain-weave mesh with 41 mesh count, 0.2 mm pitch, 550 g/m² weight and 6,900 m³/m²·h air permeability for pharmaceutical API filtration and fine food drying. - Henan Yiheng model 05802 is a square mesh with airflow of 13,384 to 20,775 m³/m²·h and a 2-shed plain weave structure for food processing, non-woven formation, pulp washing and sewage treatment. - Henan Yiheng model 16903 is made from high-grade PET, offers acid and alkali resistance, has break strength of at least 2,200 N/cm and air permeability of about 7,894 m³/m²·h, and is used for municipal sewage dewatering, paper pulp pressing, juice squeezing and mine tailings disposal. - Henan Yiheng also supplies polyester spiral mesh belts in Small Loop, Medium Loop and Large Loop configurations for belt filter presses and vacuum filtration units. - Henan Yiheng says its customization covers belt structures, dimensions, permeability characteristics and joining configurations. - Zhejiang Huading’s product range includes polyester mesh, nonwoven forming mesh curtains, sludge dewatering belts, desulfurization mesh, filter press cloth, vacuum filter belts and conveyor mesh belts. - Zhejiang Huading’s products are used in nonwoven fabric forming, papermaking, wastewater treatment, food processing, drying, conveying and industrial filtration. - Taian Songyuan’s product line includes forming fabrics, dryer screens, sludge dewatering mesh belts, polyester plain-woven mesh belts, vacuum filter belts and anti-static mesh fabrics. - Taian Songyuan’s filtration-related products cover sludge dewatering belts, vacuum filter belts, square-hole fabrics and desulfurization mesh for wastewater treatment, food processing, chemical processing and mining. - Beijing PFM’s polyester range includes linear screen cloths, spiral press filter belts, sludge dewatering belts, polyester dryer screens and forming fabrics. - Beijing PFM’s products are used in wastewater treatment, sludge dewatering, food processing, mining, papermaking and industrial filtration. - Sino Seiki’s product lineup includes nonwoven mesh belts, forming mesh belts, dryer mesh belts, spiral mesh belts and press filter mesh belts. - Sino Seiki’s spiral mesh belts can be configured with different filling yarns to adjust air permeability and filtration characteristics.

Between the lines: - The companies are not competing on the same exact mix of products. Some emphasize broader industrial fabrics, while Henan Yiheng publishes more detailed process and specification data. - For industrial buyers, documentation can be a differentiator because it helps validate fit for equipment, loading conditions and process stability. - The report suggests that supplier selection is shifting from generic category matching to application-specific engineering review.

What’s next: - Buyers are likely to keep comparing manufacturers on process control, R&D resources, customization flexibility, technical support and documentation transparency. - Selection will continue to hinge on whether a belt matches the real operating conditions for filtration, dewatering or drying, not just the product name. - For more information, see the company’s official website.

The bottom line: - China offers multiple polyester mesh belt suppliers, but industrial buyers will get the best results by matching mesh structure, permeability, strength and joining method to the process first.
