AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier serving high-performance fibers, composite materials, fiberglass products, and bearings. It provides 3D design, OEM, ODM, and multiple customization options, with documented R&D activity and new products in the past year. Production evidence includes three production lines, stated annual outputs of 100,000 aluminum gas cylinders and 10,000 carbon fiber products, and a range of manufacturing equipment. Quality-related procedures cover corrective and preventive actions, customer complaints, quality assurance, and raw-material traceability. However, the supplier reports no valid manufacturing-capacity contract with associated subcontractors, no inventory, overseas warehouse, overseas showroom, overseas agents or branches, or offline trade-show participation. Financial credibility cannot be assessed because the provided financial figures are not meaningful for evaluation and are omitted here.

Supplier typeThe supplier explicitly identifies itself as a professional technical supplier. Its stated business scope covers manufacturing and sales of high-performance fibers, composite materials, fiberglass-reinforced products, fiberglass-related products, and bearings, indicating an industrial manufacturing orientation.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, new products developed during the past year, and ODM services. It does not have an available SDK, but SDK availability is not sufficient to negate the broader documented R&D and product-development capability.

Production capacityProduction evidence includes three production lines, stated annual outputs of 100,000 aluminum gas cylinders and 10,000 carbon fiber products, and equipment including curing, CNC, assembly, pressing, heat-treatment, spinning, necking, aging, and material-handling systems. However, the supplier reports no valid manufacturing-capacity contract with associated subcontractors, so capacity governance has a documented weakness despite the stated in-house capability.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also provides 3D design, OEM, and ODM services, demonstrating broad product-design and customization support.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of customer experience with branded customers. No brand names, project details, order scope, or independently verifiable case information are provided.

Product Q&A

Q:Comparison of the advantages and disadvantages between aluminum alloy inner liner + carbon fiber fully wrapped gas cylinder (Type III) and plastic inner liner gas cylinder (Type IV)?

Type III has a wide operating temperature range (-40 to 85C) and excellent resistance to permeation, but its weight is 15% higher than that of Type IV. Type IV is the lightest but is prone to gas permeation over the long term. Currently, it is mainly used for on-board hydrogen storage.

Q:How should the bursting pressure and safety factor of a high-pressure gas cylinder be set?

According to the ISO 11439 standard, the bursting pressure must be 2.25 times the working pressure. The measured bursting pressure of the 35MPa gas cylinder needs to be > 78.75MPa, and it must pass a 5000-cycle pressure cycling test.

Q:What is the working pressure range for these cylinders?

The working pressure ranges from 15 to 30 MPa.

Q:Are the cylinder specifications customizable?

Yes, available in diameters from 60-250mm and volumes of 1-50 liters with optional features like corrosion-resistant coatings and integrated pressure gauges.

Q:What certifications do the cylinders meet?

The cylinders are certified under ISO, PED, DOT, and EN 144 standards.
