AI-Powered supplier vetting

SummaryQingdao Sincere Machinery Co., Ltd. is a China-based limited company identified as both a trading company and manufacturer/factory, with five employees and no stated parent-group affiliation. Its product range focuses on plastic pipe extrusion, water-tank machinery, sheet and board lines, recycling equipment, and related welding machinery. The supplier reports valid import/export licensing, self-operated export rights, six years of export activity, and exports accounting for 90% of sales. It offers broad customization, but its quality and service systems show material documentation gaps: no written corrective/preventive-action procedures or records, zero reported quality-control test equipment, and unknown quality-assurance and traceability status. Innovation resources appear limited, with one R&D engineer and no available SDK. An SGS audit is recorded, but the stated audit result is 0 and the report validity ended in July 2024. No customer cases are provided.

Supplier typeThe supplier is a limited company operating as both a trading company and manufacturer/factory, while another record classifies it as a trading company. Its scope covers wholesale and retail of plastics-processing equipment, machinery, and related products, and it has no stated group-company affiliation.

After-Sales capabilityThe supplier has no written corrective and preventive-action procedures or records, and its complaint-handling method is listed only as “Others.” The service-capability assessment procedure is also unspecified, so effective after-sales performance cannot be established.

R&D capabilityThe supplier reports no available SDK and has only one R&D engineer. These are explicit limitations for software or engineering-development capability, although the supplier’s broader innovation performance is not otherwise documented.

Production capacityThe supplier lists multiple specialized plastic machinery product lines, including HDPE spiral and structural-wall pipe equipment, water-pipe lines, sheet and board machines, recycling pelletizing lines, and welding machines. It is identified as a manufacturer/factory, but its five-person workforce and lack of production-scale metrics leave capacity unverified.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. This supports a broad stated customization scope, although execution evidence is not provided.
