AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier producing RF connectors, antennas, insulators, communication components, and precision auto parts. It provides 3D design, OEM, ODM, and multiple customization options, supported by machining and forming equipment. ISO9001:2015 certification and CE, RoHS, and ETL product approvals are reported. Quality and complaint-handling procedures are documented and followed, with material traceability. Production evidence includes five lines, 6–10 quality-control staff, stated PTFE output of 10,000,000 pieces, and lead times within 15 workdays in both peak and off-peak periods. Limitations include no available SDK, no new products in the past year, no valid manufacturing-capacity contract with related subcontractors, and no overseas warehouse, showroom, agents, branches, or offline trade-show participation. Financial information is limited to references to reporting years, without performance values.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier and lists precision communication electronic parts, RF products, insulators, and precision auto parts as main products. Its technical positioning is supported by reported R&D capability and engineering experience.

CertificationsThe supplier reports an ISO9001:2015 management-system certificate and states that its products have CE, RoHS, and ETL approvals. These certifications and product approvals provide explicit evidence of quality-system and compliance credentials.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, plus quality assurance and material traceability. However, it reports no overseas warehouse, showroom, agents, or branches, so service infrastructure outside its base location is limited.

Production capacityProduction capability is supported by lathe, mould, forming, drilling, and carving machines; five production lines; 6–10 quality-control staff; stated PTFE output of 10,000,000 pieces; inventory capability; and lead times within 15 workdays in both peak and off-peak seasons. A deficiency is that no valid manufacturing-capacity contract exists with related subcontractors, creating uncertainty around subcontracted capacity control.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its 3D design, ODM, and OEM services further support tailored product development and manufacturing.

Client casesThe supplier reports OEM service for popular brands, which is direct evidence of serving recognized-brand customers. The provided slices do not identify customer names, project details, volumes, or referenceable case studies, so the breadth and verifiability of these cases cannot be fully assessed.

Product Q&A

Q:Do you support free samples?

We can supply samples for free, but the delivery charges will be covered by the customer. Providing an International Express Account for Freight Collect is appreciated.

Q:What is your MOQ?

The Minimum Order Quantity is 1000 pieces per model.

Q:How is the mold fee charged?

If a new mold is required, the mold fee will be refunded to the customer when the order quantity reaches a certain amount.

Q:What is the difference between theoretical and actual weight?

Actual weight includes packaging. Theoretical weight is calculated based on the drawing, determined by the weight per meter multiplied by the profile length.
