Its product portfolio covers five major categories: air filters, oil filters, air-oil separators and more, with over 3,000 models. These products are widely used in air compressors, construction machinery, commercial vehicles and other industries, covering more than 40 large, medium and small cities in China and exporting to over 80 countries and regions worldwide.Since its establishment, the company has upheld the core value of “Technology Leads Sales, Quality Wins the Market”. It has been successively awarded honors such as National Science and Technology Small and Medium-sized Enterprise and Municipal Technology Innovation Center. Its independently patented self-cleaning filter technology has filled many gaps in the industry, making Jiangxi Sange a benchmark enterprise in China’s filter manufacturing industry.
As a core strategic partner of Jiangxi Sange, Hollingsworth & Vose (HV) is a global leader in filtration materials with a history of nearly 200 years. Headquartered in Hatzfeld, Hesse, Germany, HV operates 15 major R&D and production bases across North America, Europe and Asia, serving customers worldwide. Since its founding, HV has focused on the R&D and production of high-end filter paper, battery separators, industrial non-woven fabrics and other advanced materials. With top-tier technical strength, strict quality standards and continuous innovation, HV has become the preferred supplier for many renowned global filter manufacturers.HV filter paper features high filtration efficiency, excellent air permeability, long service life and strong corrosion resistance, making it ideal for industrial high-load and high-precision filtration scenarios. This aligns perfectly with Jiangxi Sange’s product positioning of targeting the high-end market and pursuing ultimate quality. At present, most filter elements of Jiangxi Sange adopt HV filter paper. Based on shared quality values, the two parties have established a long-term, stable, mutually trusting and win-win in-depth partnership to provide high-quality filtration solutions for global customers.
On the morning of the visit, the HV delegation, accompanied by Chairman Han Shengjun and the core management team, visited the company’s product exhibition area, R&D and testing center, raw material warehouse and production workshop.In the product exhibition area, a full range of exquisitely crafted filters were neatly displayed, covering various application scenarios from large industrial air filters to precision oil filters and air-oil separators. The HV team carefully inspected each product, inquired about R&D design, performance parameters, production processes and market applications, and spoke highly of Jiangxi Sange’s rich product categories, stable quality and refined craftsmanship. They particularly recognized the company’s achievements in realizing domestic substitution of key components and reaching advanced industry standards.
The delegation then entered the R&D and testing center, the core hub for technological innovation. Equipped with industry-leading testing equipment—including filtration efficiency testers, air permeability detectors and durability testers—the center conducts full-process quality inspection and performance verification on raw materials, semi-finished products and finished products, providing strong support for product R&D innovation and quality stability.HV technical engineers observed key testing processes such as filter paper performance testing and filter element filtration efficiency inspection on site, carefully reviewed quality inspection reports, and conducted in-depth exchanges with Jiangxi Sange’s technical team on filter paper selection, testing standards and quality control points. They provided professional guidance on technical details and parameter optimization during testing, helping the company further improve its quality control system and enhance testing accuracy.
In the production workshop, the delegation inspected the semi-automatic production process including filter paper cutting, folding, bonding, assembly, inspection and packaging. The clean and orderly production environment, advanced and efficient production equipment, standardized operation procedures and strict quality control left a deep impression on the HV team.During the tour, HV technical engineers focused on the application of HV filter paper in production, inquiring about key aspects such as storage conditions, cutting process adaptability and folding precision control. They provided on-site guidance to optimize operation details to ensure the superior performance of HV filter paper is fully reflected in finished products, guaranteeing filtration accuracy, air permeability and service life from the source.HV’s procurement manager also held in-depth communication with Jiangxi Sange’s procurement team on supply chain management, raw material delivery and quality feedback mechanisms, reaching consensus on further optimizing procurement processes, ensuring stable supply of raw materials and improving cooperation efficiency.
Since its establishment, Jiangxi Sange has always regarded quality as the lifeblood of enterprise development. As a world-leading filter paper supplier, HV’s high-quality products and professional technical services have been a crucial guarantee for the steady improvement of Jiangxi Sange’s product quality. Over the years, the two sides have worked side by side to carry out all-round cooperation in technology R&D, quality control and market expansion, jointly overcoming multiple technical challenges and promoting continuous upgrading of product quality, winning wide recognition from global customers.This visit by the HV team provided a valuable learning opportunity for Jiangxi Sange. Both sides expressed hope to take this exchange as an opportunity to further deepen technical collaboration and resource sharing, explore more cooperation areas, and jointly promote the high-quality development of the filtration industry. They also agreed to strengthen the frequency of technical exchanges, establish a regular communication mechanism, timely share cutting-edge technologies, market trends and quality control experience, and jointly address industry challenges to create a new situation of mutual benefit and win-win results.In response to technical difficulties encountered by Jiangxi Sange’s technical team in filter paper application, HV engineers patiently provided practical solutions and optimization suggestions, offering important references for the company’s subsequent technical improvement and product upgrading. Both parties also conducted in-depth discussions on cooperation directions such as joint R&D of new filtration materials, co-formulation of industry quality standards and expansion of overseas high-end markets, reaching many preliminary consensuses and laying a solid foundation for deeper and broader cooperation in the future.
