AI-Powered supplier vetting

SummaryGuiyang Baiyun Alloy Casting Factory is a China-based, state-owned crankshaft manufacturer established in 1997, with reported operations dating to 1992 and more than three decades of crankshaft-material experience. It operates a 13,218 m² plant, has 84 employees, and reports annual productivity of 80,000 pieces across American, German, Japanese, and Korean series. The supplier holds an ISO 9001:2015 management-system certificate and reports 11–20 quality-control staff. It claims OE-manufacturer quality standards and a one-year/100,000-kilometer crankshaft guarantee, but the broader after-sales-service capabilities are not verified. R&D, customization, traceability, overseas infrastructure, and several operational controls remain insufficiently documented. A BV audit is recorded with an evaluation result of 0 and a stated validity period from April 28, 2024 to April 27, 2025; the meaning of the result is not defined in the provided data.

Supplier typeThe supplier is identified as Guiyang Baiyun Alloy Casting Factory, a state-owned Chinese company focused on crankshaft production for automotive aftermarket applications and auto/motorcycle parts. Its reported operating history spans more than three decades, indicating a specialized manufacturing profile rather than a general trading business.

CertificationsThe supplier reports an ISO 9001:2015 certificate. A BV audit is also recorded, but the audit result is listed as 0 without an interpretation, so the audit record cannot independently establish a positive compliance outcome.

After-Sales capabilityThe supplier states that its crankshafts are covered by a one-year and 100,000-kilometer guarantee for regular use and describes service to a global market. However, specific repair, replacement, response-time, or overseas support capabilities are not provided.

R&D capabilityThe supplier reports more than three decades of crankshaft-material research, production, and development, plus three years of total R&D engineer experience and a focus on high-end and modified-engine crankshafts. Specific new-product launches, R&D documentation, SDKs, 3D design, or other structured innovation outputs remain unknown.

Production capacityThe supplier reports a 13,218 m² manufacturing plant, 84 employees, and annual productivity totaling 80,000 pieces across four regional product series. These stated facilities and capacity figures provide explicit evidence of established production capability.
