AI-Powered supplier vetting

SummaryLiangshan Changzai Machinery Manufacturing Co., Ltd. is a China-based manufacturer of semi-trailer parts, including axles, suspension systems, leaf springs, landing gear, king pins, fifth wheels, brake chambers, air tanks, and twist locks. It reports ISO 9001:2015 certification, 10 production lines, 6–10 quality-control staff, and export activity since 2011 across multiple regions. Product customization is supported by R&D responsibilities, design software, and documented design review and validation records, but the supplier reports only one R&D engineer and no patents or available SDK. Overseas service infrastructure is limited, with no overseas showroom, agents, branches, or offline trade-show participation. Financial information is referenced by year but contains no financial performance figures, so credibility cannot be fully assessed. No specific customer cases are provided.

Supplier typeThe supplier is identified as a Chinese manufacturer specializing in semi-trailer parts and related mechanical equipment. Its stated product range includes axles, suspension, leaf springs, landing gear, king pins, fifth wheels, air brake chambers, air tanks, and twist locks, supporting classification as a specialized semi-trailer-parts manufacturer.

CertificationsThe supplier reports holding an ISO 9001:2015 management-system certificate. This is explicit certification evidence, although no additional certifications or certificate-scope details are provided.

After-Sales capabilityThe supplier has no overseas showroom, agents, branches, or reported offline trade-show participation, and lists zero countries with overseas services. It does report written service procedures with implementation records and service lead times within 15 working days, but the lack of overseas service infrastructure is an explicit limitation.

Production capacityThe supplier reports 10 production lines, 6–10 quality-control staff, and a broad semi-trailer-parts manufacturing scope. It also states one-month peak and off-peak fulfillment times in one record; another service-related record states lead times within 15 working days, creating some measurement-context ambiguity, but the production infrastructure is explicitly documented.

Customization capabilityThe supplier states that its R&D function develops new products according to customer requirements and maintains design documentation covering review, verification, and validation. This directly supports customer-specific development capability, although the R&D team is limited to one reported engineer.
