AI-Powered supplier vetting
SummaryWenzhou Qianfeng Machinery Co., Ltd. is a China-based limited company in Zhejiang, identified as a combined business entity. The supplier states it has 28 years of expertise, over 40 patents, ISO-certified quality, and more than 2,000 clients worldwide; however, its stated establishment date is February 26, 2025, creating an unresolved inconsistency regarding organizational history. Its product portfolio focuses on PP/PE woven-bag production equipment, including automatic cutting and sewing, printing, gusseting, and baling machinery. Reported annual productivity is 200 sets each for two machine categories. An SGS audit record is provided and is valid from March 28, 2025 to March 27, 2026, but supplier-management certification is listed as NIL. Export sales are reported at 11%–20%. Evidence is insufficient to confirm after-sales infrastructure, financial credibility, R&D/customization services, or overseas service channels. No financial data is included.
Supplier typeThe supplier is identified as a combined business entity and a limited company, operating from Zhejiang, China. The legal/business form is explicitly provided, but no more detailed classification of the combined structure is available.
R&D capabilityThe supplier claims 28 years of expertise as a national high-tech enterprise, more than 40 patents, and smart woven-bag production solutions. Nevertheless, specific R&D service capabilities, new-product development, SDK availability, ERP integration, and related sustainability systems are marked unknown, so the breadth and current effectiveness of innovation capability remain unverified.
Production capacityThe supplier offers a focused range of woven-bag equipment and reports annual productivity of 200 sets each for automatic cutting and sewing machines and cylinder-free reel-to-reel printing machines. Its stated product scope and output support production capability for these categories, although capacity for other products is not provided.
Client casesThe supplier states that its smart solutions are trusted by more than 2,000 satisfied clients worldwide, with reported customer markets across Southeast Asia, the Middle East, Central Asia, Russia, and Africa. This is evidence of broad claimed customer reach, but no named customers, project details, or independently verifiable case studies are provided.
