AI-Powered supplier vetting

SummaryThe supplier is a limited company with 98 employees and a product range covering pneumatic, brass, plastic and related fittings, PU hose and speed controllers. It reports ISO9001 experience and lists ISO9001:2015, ISO45001:2018 and ISO14001 certifications, plus RoHS capability. Quality assurance and supplier-service assessment procedures are documented, while complaint handling has a procedure but no written records. The supplier offers broad customization and ODM services, reports new products within the past year, maintains R&D documentation and 47 patents. Production-related strengths include in-stock capability, stated lead times within 15 working days in both seasons, and a plant exceeding 10,000 square meters. Limitations include no OEM service for popular brands, no overseas warehouse, showroom, agent or branch, no valid manufacturing contract with related subcontractors, and no available SDK. Financial credibility and customer-case evidence remain insufficient for a conclusive assessment.

Supplier typeThe supplier is identified as a limited company, independent of a larger company group, with 98 employees and a plant area exceeding 10,000 square meters. Its stated product scope includes pneumatic, brass and plastic fittings, PU hose and speed controllers, indicating a specialized industrial-components manufacturer.

CertificationsThe supplier states that it has quality assurance in quality-control processes, previously obtained ISO9001, and lists ISO9001:2015, ISO45001:2018 and ISO14001 certifications, together with RoHS capability. The slices support a positive certification and quality-system assessment, although certificate validity details are not provided.

After-Sales capabilityThe supplier has a corrective and preventive action procedure with followed records and a customer-complaint procedure, but complaint handling has no written records. It also lacks overseas warehouses, showrooms, agents and branches, and reports zero countries with overseas services, limiting its demonstrated international after-sales infrastructure.

R&D capabilityThe supplier reports new products within the past year, provides R&D design input/output, review, verification and validation records, and has 47 patents. These are explicit indicators of active innovation, although no SDK is available and software-instrument capability is confidential.

Production capacityProduction evidence includes a plant exceeding 10,000 square meters, in-stock capability, stated average lead times within 15 working days in both peak and off-season, and documented supplier-service assessment procedures. A material risk remains because the factory and related subcontractors do not have a valid manufacturing contract.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization and flexible customization, together with ODM services. R&D personnel are responsible for product improvement and production support, and supporting design documentation is available for audit, demonstrating broad customization capability.

Product Q&A

Q:Threaded connections may have gaps

Threaded connections may have gaps and slight air leaks, which require wrapping with tape to solve.

Q:Poor contact of sealing ring

The cross-section of the trachea was not cut flat, resulting in poor contact of the sealing ring and causing air leakage. The trachea was cut flat and reinserted into the joint.

Q:Damaged sealing ring

Excessive air pressure and unclean gas can cause damage to the sealing ring. It is recommended to choose high-pressure and corrosion-resistant connectors according to actual usage needs, and install filters in the air circuit.

Q:Aging of sealing ring

During the use of the joint, the aging of the sealing ring is inevitable. Over time, there may be air leakage, and the presence of moisture in the compressed air will exacerbate the aging of the sealing ring. When using the joint, attention should be paid to this situation.

Q:What is the use pressure range?

The use pressure range is 0~1.0Mpa with a negative pressure of -100Kpa.
