AI-Powered supplier vetting

SummaryShanghai Trisun Parts Manufacture Co., Ltd. is identified as a Chinese manufacturer established in 2001, focused on mechanical, pump, compressor, and automotive sealing products. The provided information indicates broad production coverage, more than 10 production lines, multiple production bases, and reported mechanical-seal output of approximately 9–10 million pieces. The supplier cites OEM or cooperation relationships with SANDE, DENSO China, ITT, Volkswagen, Bizer, Flowserve, and MTU. Quality-related evidence includes WRAS, FDA, and ISO 14001:2004 certificates, although supplier-management-system certification is listed as NIL. Production and customer-case evidence is relatively strong, while after-sales service, customization processes, and financial credibility cannot be fully assessed from the available non-financial information.

Supplier typeThe supplier is explicitly classified as a manufacturer and operates as a limited company in Shanghai, China. It was established in 2001, supporting an established manufacturing identity rather than a trading-only profile.

CertificationsThe supplier reports WRAS and FDA material-quality certificates and an ISO 14001:2004 environmental management certificate. However, supplier-management-system certification is explicitly listed as NIL, so the certification profile is positive but not comprehensive.

R&D capabilityThe supplier offers a broad range of seal and valve products, including dry gas seals, welded metal bellow seals, cartridge seals, and automotive applications. It reports three R&D engineers and more than 20 years of development, indicating some product-development capability, but no explicit evidence of patented technology or measurable innovation outcomes is provided.

Production capacityProduction capability is supported by more than 10 production lines, reported mechanical-seal output of approximately 9–10 million pieces, three production bases in Shanghai, Wenzhou, and Jiangsu, and a stated one-month off-peak lead time. The records contain differing workforce and workshop-area figures, so the exact current operating scale should be verified.

Client casesThe supplier reports appointed OEM or cooperation relationships involving SANDE, DENSO China, ITT, Volkswagen, Bizer, Flowserve, and MTU. A separate trade record identifies CARBONMASTER INDUSTRIAL SALES INC as an associated buyer, but it records only one transaction and does not independently validate the broader customer claims.
