SummaryJulu County Hengfeng Seal Factory is a privately owned Chinese manufacturer established in 2020, with 11 employees and a 1,500 m² plant in Hebei. It produces asbestos-free and other industrial gaskets, sealing rings, packing pads, cushions, and related products. The supplier states that product dimensions, materials, and surface colors can be customized, and that production follows ministerial and national standards. It also claims more than 20 years of production experience, although this is not fully reconciled with the stated establishment date. A BV audit is recorded for the period from October 16, 2024 to October 15, 2025, but the audit result is listed as “0” without interpretation. Export activity began in 2023, with 21%–30% of total sales reportedly from exports and exports conducted partly through agents. Evidence is insufficient to verify financial credibility, innovation systems, customer cases, detailed quality controls, or formal certifications.

Production capacityThe supplier reports a 1,500 m² manufacturing plant, 11 employees, production of multiple gasket and sealing-product categories, and production organized according to ministerial and national standards.
