AI-Powered supplier vetting

SummaryHefei WNK Smart Technology Co., Ltd. is a China-based limited company operating in electrical and electronics, with stated activities covering sensor and transmitter production, R&D, sales, and services. The supplier reports ISO9001:2015 certification, two production lines, a 3,500 m² manufacturing area, 77 employees, and documented annual output of 30,000 temperature transmitters and 60,000 pressure transmitters. Its materials describe technical innovation, PROFIBUS transmitter development, broad export markets, and stated order fulfillment within 15 working days in both peak and off-peak periods. Evidence is insufficient to assess after-sales capability, customization capability, financial credibility, or customer cases. The supplier registration date is stated as May 2025, while another record states establishment in 2014 and a background description says founded in 2004; this inconsistency should be verified.

Supplier typeThe supplier is identified as a limited company and combined business entity in China, with its business type also described as a trading company. Its stated operations focus on producing, researching, selling, and servicing sensors and transmitters, while its commercial trade engagement is electrical and electronics.

CertificationsThe supplier explicitly reports an ISO9001:2015 certificate. It also reports earlier conformity with GB/T 19001-2008 / ISO 9001:2008 and PROFIBUS certification for a transmitter product, providing direct evidence of quality-system and product-related certification claims.

R&D capabilityWNK explicitly states commitments to new-product development and technical innovation, participation in Ministry of Science and Technology innovation projects, and recognition as a promising technology enterprise. It also claims development of PROFIBUS transmitters and proprietary intellectual property, while reporting four R&D engineers.

Production capacityThe supplier reports 77 employees, approximately 3,500 m² of manufacturing space, two production lines, and production of 30,000 temperature transmitters and 60,000 pressure transmitters annually. It also states order fulfillment within 15 working days during both peak and off-peak periods, indicating documented production capacity, although the differing workshop-area figures and company-history dates should be verified.
