【Summary Description】
Hebei Sienuo Achieves Mass Production of DIN 61200 Standard Industrial Wool Felt
Hebei Sienuo continues to advance the standardized production of industrial felt and has realized stable mass production of German DIN 61200 standard industrial wool felt. All technical indicators of the products, including hardness, density and thickness tolerance, are fully benchmarked against the German DIN 61200 standard. The company can provide European customers with industrial wool felt plates, strips and custom die-cut shaped parts that comply with German standards, further strengthening its supply capacity for European and American markets including Germany and the Czech Republic.
DIN 61200 is an authoritative and widely adopted German standard for industrial wool felt, which mainly regulates the hardness grading, bulk density and tolerance range of felt products. It is extensively applied in industrial scenarios such as mechanical sealing, shock absorption and buffering, oil absorption and filtration, hardware polishing, as well as heat insulation and noise reduction, serving as a core quality evaluation criterion for European equipment purchasers. The standard sets stringent requirements on felt density uniformity, compression and resilience performance, and thickness deviation control, raising high thresholds for the entire process including raw material selection, felting technology and finished product testing.
Leveraging the industrial cluster advantages of Nangong felt industry, Sienuo has optimized the complete production process covering raw material screening, wet felting shaping and precision post-processing, and built supporting testing stations. Each batch of DIN 61200 felt is subject to sampling inspection on density, hardness and thickness, with strict tolerance control for multiple hardness grades from W2 to W5. This ensures consistent product performance across different batches. The company provides diversified deep-processed products including felt rolls, plates and strips, as well as die-cutting and turning processing parts, catering to diverse application scenarios of European mechanical equipment, hardware polishing, sealing and shock absorption industries.
According to the company’s foreign trade team, DIN 61200 standard industrial wool felt has been exported to the EU in bulk and can be matched with DIN 61206 series products to meet the procurement demands of overseas customers under different working conditions. A complete traceable quality record system has been established covering raw material warehousing, production process control and finished product inspection and delivery, facilitating factory audits by overseas customers and supporting the provision of corresponding test data documents.
The scaled production of DIN 61200 standard felt marks a key milestone for Hebei Sienuo’s in-depth layout in the European industrial consumables market. Moving forward, the company will continue to benchmark against German industrial standards, continuously optimize production techniques and quality inspection systems, and advance the dual development of industrial felt and children’s felt products. With consistent and reliable product quality, Sienuo will further expand overseas markets and empower domestic felt products to integrate into the European industrial supply chain.
