AI-Powered supplier vetting

SummaryNingbo Union Power Machinery Co., Ltd. is a China-based limited company established in 2007, specializing in plastic injection molding machines. It reports CE and ISO certification, OEM service for well-known brands, customization from samples or designs, documented quality and service procedures, and online and permanent after-sales support. Manufacturing-related strengths include valid contracts with associated subcontractors, in-stock capacity, finished-product inspection instructions, and stated one-month lead times in both peak and off-peak periods. However, the evidence indicates no SDK availability, no overseas warehouse or showroom, and incomplete information regarding financial performance, environmental assessment, and customer cases. The submitted data also contains inconsistencies: one slice reports 17 employees while another reports 50 quality-control staff and two production lines. These discrepancies limit confidence in assessing operational scale.

Supplier typeThe supplier is identified as Ningbo Union Power Machinery Co., Ltd., a China-based limited company established in 2007, specializing in injection molding machines. It is not indicated as part of a larger company group.

CertificationsThe supplier explicitly states that it holds CE and ISO certification. The provided information does not specify the ISO standard, certificate numbers, issuing bodies, or validity periods.

After-Sales capabilityThe supplier reports online technical support, English technical files, pre-delivery machine testing, a one-year guarantee, permanent after-sales inquiry service, and a 24-hour email response commitment. It also reports written and followed procedures for service assessment, corrective actions, and complaint handling, supporting a documented service process.

R&D capabilityThe supplier offers customized machine design and reports a high-performance European B&R control system, but explicitly has no available SDK. The evidence does not establish broader R&D strength; the reported total R&D engineer experience is limited to one year.

Production capacityThe supplier reports valid manufacturing-capacity contracts with associated subcontractors, in-stock service capacity, standardized finished-product inspection instructions, two production lines, and one-month lead times in both peak and off-peak seasons. However, the data contains a scale inconsistency between the reported 17 total employees and 50 quality-control staff, so overall capacity should be verified.

Customization capabilityThe supplier explicitly offers customized designs according to requirements and supports customization from samples, designs, full specifications, and minor modifications. This directly indicates broad customization coverage for its injection molding machine offering.
