AI-Powered supplier vetting

SummaryQingdao Sanzhuji Technology Co., Ltd. is a China-based manufacturer and factory in Qingdao, Shandong, focused on manufacturing and processing machinery, including green sand processing production lines, molds, metal structures, machine parts, and construction machinery. It has stated quality assurance, raw-material traceability, inventory capacity, and reported peak- and off-season lead times within 15 working days. Its R&D profile is limited: it is identified as a professional technical supplier and provides customization from designs, but has no new products reported in the past year and does not provide 3D software design, ODM, SDK, or well-known-brand OEM services. After-sales controls are weak because no written complaint-handling or corrective/preventive-action procedures or records are available. Overseas support is also limited, with no overseas warehouse, showroom, agents, branches, or prior offline trade-show participation. The provided information does not establish financial credibility or...

Supplier typeThe supplier is explicitly identified as a manufacturer/factory and limited company based in Qingdao, China, engaged in manufacturing and processing machinery. Its stated primary product is a green sand processing production line, while its business scope also covers molds, metal structures, machine parts, and construction machinery.

CertificationsThe supplier is reported to have one national science and technology progress award, and a TUV Rheinland audit report covering March 7, 2025 to March 6, 2026 is provided. However, the audit result is recorded as 0 without an explained interpretation, so broader certification compliance cannot be confirmed.

After-Sales capabilityAfter-sales infrastructure is limited: the supplier has no written complaint-handling or corrective/preventive-action procedures or records, no overseas warehouse, showroom, agent, or branch, and has not participated in offline trade shows. Inventory capacity and multiple payment terms are available, but these do not establish effective after-sales management.

Production capacityThe supplier has manufacturing and processing machinery capabilities, inventory capacity, and stated annual productivity for several machines, including 100 sand molding machines, 40 rotator mixers, 20 planetary rotor sand mixers, 20 continuous resin sand mixers, and 30 conveyor shakeouts. It also lists flame-cutting, lathe, and milling equipment, although manufacturing subcontracting lacks a valid contract and finished-product inspections have instructions but no written records.

Customization capabilityThe supplier explicitly provides customization from designs, and this capability is recorded both under R&D and design services. However, it does not provide 3D software design, so customization is supported from customer-provided designs rather than through an evidenced full digital design service.
