Flocked Swabs Manufacturing Conditions and Certification

As a professional manufacturer of flocked swabs, Huachenyang (Shenzhen) Technology Co., Ltd. has always controlled every production link with strict standards, adhered to the bottom line of compliance, and built a solid safety line for product quality with professional strength. Flocked swabs are widely used in key scenarios such as medical testing, nucleic acid sampling and scientific research experiments, and their quality is directly related to the accuracy of test results and the safety of users. Therefore, the standardization of production conditions and the completeness of certification qualifications are the core commitments of our company to customers and the rigid requirements for industry access.

In terms of production conditions, we have built a full-process standardized control system, and every step from production environment, process equipment to raw material selection follows the highest industry standards. The production workshop is built in strict accordance with medical device production specifications. The core production area meets ISO Class 7 (10,000-class) clean standards, and some key processes are upgraded to ISO Class 8 (100,000-class) clean environment. It adopts full closed management, equipped with high-efficiency air purification system and automatic temperature and humidity control system, which stabilizes the temperature at 18-28℃ and the relative humidity at 50-65%, ensuring that the number of particles ≥0.5μm in the air is not more than 3500 per liter, and eliminating pollution such as dust and microorganisms from the source. The workshop is more than 500 meters away from pollution sources, with no water accumulation or weeds around, fully complying with the requirements of the “Hygienic Standards for Disinfection Product Manufacturing Enterprises”, providing a clean and safe environmental foundation for the production of flocked swabs.

Process equipment and process control are the core guarantee of product quality. We have introduced imported automatic flocking production lines and adopted electrostatic flocking technology to accurately control parameters such as voltage and fiber jet speed, ensuring that more than 3000 nylon fibers with a diameter of 7-12 microns are evenly distributed per square millimeter, and the deviation of fiber perpendicularity is controlled within ±5°, so as to ensure the sampling efficiency and sample release rate of the swab tip. The whole production process is automated, from swab rod forming, flocking, cutting to packaging and sterilization, reducing the pollution risk caused by manual contact. At the same time, a strict in-process quality inspection mechanism is established. Each batch of products is randomly sampled and tested, focusing on checking physical indicators such as the firmness of the swab tip, fluffing and connection strength, ensuring that the number of fiber chips of the dry swab tip is no more than 3, no fiber falls off in the wet state, and the connection strength at the breaking point is ≥2N, fully complying with relevant technical requirements. With the unique jet-type nylon fiber implantation technology, our flocked swabs greatly improve the sample collection and release capacity, and the sample release rate is as high as 95% or more.

Raw material selection is the first pass of product safety. We strictly select raw materials that meet medical standards. The swab tip is made of medical-grade nylon fiber or polyester fiber, without fluorescent whitening agents or irritating odors, and complies with ISO 10993 biocompatibility standards; the swab rod is made of polymer materials such as PE, PP or ABS, without harmful components such as wood and bamboo, with strong toughness and not easy to break, and is equipped with a clear breaking point for easy operation after sampling. The adhesive adopts medical-grade thermosetting epoxy resin, which is non-toxic and residue-free, and has passed cytotoxicity and sensitization tests to ensure that it will not pollute the sample or cause skin or mucosal irritation to users. All raw materials are from regular suppliers, and complete certificates of conformity must be provided before entering the factory, which can be put into production only after passing the inspection. Our flocked swabs are free of DNA enzymes, RNA enzymes and endotoxins, avoiding sample degradation or pollution.

In terms of certification qualifications, we have comprehensively laid out dual domestic and international certifications to ensure the compliant circulation of products and gain wide market recognition. In terms of domestic certification, we have obtained the “Medical Device Production License” and “Medical Device Registration Certificate”, clarifying the compliant identity of flocked swabs as Class II medical devices, and strictly following national standards such as YY/T 1739-2020 “General Technical Requirements for Medical Swabs” and YY/T 0911-2013 “General Technical Conditions for Medical Sampling Swabs” to ensure that product performance meets the standards and can be legally used in domestic medical, disease control and other fields.

In terms of international certification, we have passed the ISO 13485 medical device quality management system certification, covering the whole process of R&D, production, inspection and sales, ensuring the stable and controllable quality of each batch of products; we have also obtained international authoritative certifications such as EU CE certification, US FDA certification and Australian TGA certification, complying with international market access standards, and our products can be exported to many countries and regions around the world. In addition, our sterilization process has passed strict verification, using ethylene oxide or gamma ray sterilization to ensure that the sterility assurance level (SAL) of the product is ≤10⁻⁶, and the residual amount of ethylene oxide is ≤10μg/g, complying with relevant standards such as GB/T 14233.1-2008. Each batch of products is provided with a complete inspection certificate and CoA report, which can be inspected by customers and regulatory authorities at any time. Our products also have CE 0826 and CE 0197 certifications, meeting the export requirements of the European market.

As a responsible manufacturer, Huachenyang (Shenzhen) Technology Co., Ltd. always puts product quality and safety in the first place, strictly follows production standards, continuously improves the certification system, and provides customers with reliable flocked swab products with transparent production processes and complete certification qualifications. We are willing to take the initiative to show the production workshop, testing process and certification documents to every customer, accept the supervision and inspection of customers, and guard the accuracy and safety of every sampling and testing with professionalism, compliance and integrity. Our company is located at the 8th Floor, No. 4 Workshop, No. 128 Shangnan East Road, Huangpu Community, Xinqiao Street, Bao’an District, Shenzhen, and we welcome customers from all over the world to consult and cooperate.
