AI-Powered supplier vetting

SummaryLiuzhou Pinmo Sealing Sci-Tech Co., Ltd. presents broad manufacturing and technical-service capabilities, including OEM for recognized brands, ODM services, product customization, and stated experience across multiple international markets. Its management certifications include TS 16949, ISO 14001, ISO 9001, and SA 8000. The supplier reports inventory capability, standardized finished-product inspection instructions, and lead times within 15 working days in both peak and off-peak periods. However, evidence is incomplete regarding after-sales support, financial strength, customer references, and contract status. The supplier lacks an SDK, overseas warehouses, overseas showrooms, overseas agents or branches, and reported participation in offline trade shows. It also reported no regular fire drills during the past year.

Supplier typeThe stated business scope covers technical services, technology development and transfer, seals, plastic and rubber products, mechanical parts, glass-fiber-reinforced plastic products, and auto parts. The supplier also describes a factory, broad product range, and worldwide industry service, indicating a manufacturer with technical-service capabilities rather than a narrowly focused trading profile.

CertificationsThe supplier reports holding TS 16949, ISO 14001, ISO 9001, and SA 8000 certifications. These explicitly indicate coverage of automotive quality management, environmental management, quality management, and social accountability systems.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has R&D engineers with total experience in the stated 6–10 range. However, it reports no available SDK, so its innovation support is demonstrated through product development and ODM rather than software-development integration.

Production capacityThe supplier reports inventory capability, finished-product inspection instructions that are uniformly followed, annual output information of 10,000,000 sets, and lead times within 15 working days in both peak and off-peak seasons. Its manufacturing capacity is therefore explicitly supported, although the manufacturing-contract status is unknown.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, and minor customization. It also reports ODM service availability, providing direct evidence of multiple customization routes.
