AI-Powered supplier vetting

SummaryThe supplier is a limited company in Jiangyin, Jiangsu, with 58 employees and a stated business scope covering manufacturing, forgings, mining machinery, general equipment, machine parts, and related sales. Its offered products are hydraulic cylinders and forging shafts. It reports broad customization and ODM capabilities, recent new-product development, and one production line with stated output for steel mill rolls and hydraulic cylinders. Quality inspection instructions are documented and uniformly followed. However, it has no in-stock capacity, overseas warehouse, overseas showroom, overseas agents or branches, and reports no offline trade-show participation. No certification information or customer cases are provided. Financial records are referenced for 2021–2023, but the slices do not provide sufficient financial performance evidence for a credibility assessment. The supplier’s stated status as a trading company, combined with manufacturing-related scope and valid contracts with associated...

After-Sales capabilityThe supplier reports no overseas warehouse, overseas showroom, overseas agents or branches, and offers services in zero overseas countries. These stated limitations indicate weak international after-sales infrastructure, although no complete after-sales policy or response capability is provided.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and supports customization from samples and designs through full customization. However, total R&D engineer experience is reported as below five years and no SDK is available, so the evidence supports product-development capability but not a complete advanced-innovation assessment.

Production capacityThe supplier lists extensive equipment, one production line, stated annual outputs of 10,000 tons for steel mill rolls and 3,000 tons for hydraulic cylinders, and valid contracts with each associated subcontractor. It also has 15 qualified service-capability suppliers and written assessment procedures, although it reports no inventory capacity and the lead-time entry is unclear.

Customization capabilityBoth R&D and design-service records explicitly list customization from samples, customization from designs, minor customization, flexible customization, and full customization. This is direct evidence of broad customization coverage.

Product Q&A

Q:Why choose forging rather than casting for heavy duty couplings?

Forged coupling has continuous dense metal grains. Its mechanical properties greatly outperform common castings, delivering ultra-high strength, impact resistance, fatigue resistance and good resistance to alternating loads.

Q:What products can you buy from us?

We supply shaft and roller forgings, including alloy steel, mold die steel, and stainless steel types.

Q:Why choose us over other suppliers?

We have complete producton equipments and rich experience on forging and heat treatment.We could provide chemical composition test report, machinical property test report, UT/MT test report,etc.

Q:What is the minimum order quantity?

The minimum order quantity is 1 piece.

Q:Do you offer ODM services?

Yes, we provide ODM services with customized options for our customers.
