AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier offering 3D software design, SDK support, ODM, OEM, and multiple customization options. It reports brewing-equipment production of 1,000 sets annually, exports to a broad range of regions, and generally states lead times of within 15 working days off-season and one month during peak season, although another slice reports within 15 working days during peak season. CE certification and regular fire drills are documented. After-sales services include installation, debugging, maintenance, repair, and training. Financial records are indicated for 2021–2023, but no financial performance values are provided. Innovation evidence is weak because no new products were launched in the past year, and quality-control test equipment is reported as zero. The supplier states OEM service for popular brands, but no specific customer names or case details are provided.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and provides 3D software design services. This supports classification as a technical and design-capable supplier rather than only a standard product manufacturer.

CertificationsThe supplier reports sustainable-development and product certification capability through CE certification. This is explicit certification evidence, although no additional certification types are listed.

After-Sales capabilityThe supplier has documented procedures and records for handling customer complaints and service corrective/preventive actions. It offers installation, debugging, maintenance, repair, and training, with service coverage determined by customer demand; however, it has no overseas warehouses, showrooms, agents, or branches.

Production capacityThe supplier reports annual brewing-equipment production of 1,000 sets, exports to numerous global regions, and an off-season lead time within 15 working days. It also reports one month for peak-season fulfillment in one slice, while another states within 15 working days during peak season, so peak-season capacity information is inconsistent.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization capability.

Product Q&A

Q:How are the springs packed before shipment?

Springs are first packed in anti-rust packaging (plastic bags/rust-proof paper), then placed in sturdy wooden cases, cartons or pallets for sea/air shipment, suitable for long distance international transportation.

Q:Do you offer free samples before bulk orders?

Small standard samples are available for free, customer only needs to pay for express shipping cost. Custom samples may require a small tooling fee.

Q:Can you produce springs according to our drawings or samples?

Yes, we specialize in custom spring manufacturing. We can produce exactly to your drawings, samples or specific load/dimension requirements. Our engineering team can also provide design support if needed.
