AI-Powered supplier vetting

SummaryThe supplier operates in mechanical parts, general equipment, mold, hardware, and intelligent basic manufacturing equipment, with stated capabilities covering CNC machining, drilling, forging, sandblasting, cutting, and heat treatment. It offers extensive customization, ODM, and OEM services, but reported no new product information in the past year and has no available SDK. Service management procedures, corrective and preventive actions, and complaint-handling records are documented. However, the supplier reports no overseas warehouse, showroom, agents or branches, overseas service coverage, or offline trade-show participation. No supplier-management-system certification is reported. Production capacity is stated as 30,000 tons annually, with six production lines and two quality assurance/control inspectors in one record; another record states 21–30 quality-control staff, creating a data inconsistency. Customer-specific cases are not provided.

Supplier typeThe supplier is a manufacturer and processor of mechanical parts and components, molds, hardware, general equipment, and intelligent basic manufacturing equipment. Its listed facilities include CNC, milling, drilling, forging, cutting, sandblasting, and heat-treatment equipment, indicating an industrial manufacturing profile rather than a trading-only business.

CertificationsThe supplier-management-system certification field is explicitly reported as NIL. This confirms that no such certification is evidenced in the provided information.

After-Sales capabilityThe supplier has written procedures and records for service capability, corrective and preventive actions, and customer complaint handling. However, it reports no overseas warehouse, showroom, agent or branch, overseas service coverage, or offline trade-show participation; service proximity is identified as Tianjin Port and stated lead times are within 15 workdays in both seasons.

Production capacityThe supplier reports six production lines, a stated annual productivity of 30,000 tons, and equipment covering machining, forging, cutting, sandblasting, and heat treatment. Quality-control staffing is inconsistent across records—two inspectors in one entry versus 21–30 quality-control staff in another—so capacity is evidenced, but staffing data requires verification.

Customization capabilityThe supplier explicitly provides customization from designs and samples, minor and full customization, flexible customization, ODM services, and OEM services for well-known brands. The repeated evidence across product-design and OEM fields supports a strong customization offering.

Product Q&A

Q:What is the difference between forging and casting?

Forging transforms solid metal into a desired shape through plastic deformation (hot or cold processing), refining the internal grain structure. Casting involves melting metal into a liquid state and pouring it into a mold to solidify. Forging offers superior strength and density compared to casting.

Q:How to choose high-quality circular forgings?

Select forgings by checking external dimensions and surface conditions for defects like cracks or scratches. Internally, verify chemical composition, mechanical properties (tensile strength, hardness), and structural integrity using specialized instruments to detect fractures or shrinkage.

Q:What are the characteristics of the forging process for circular blank forgings?

The process includes pier roughening, elongation, punching, and expanding. Free forging typically uses a horse screw to expand holes, while ring rolling uses rolling mills. Both methods ensure solid-to-solid shape transformation at high temperatures.

Q:What materials are available for these hollow shafts?

We offer carbon steel (1020, 1035, 1045, Q235, Q345), alloy steel (40Cr, 20CrMnTi, 42CrMo4), and stainless steel (SS304, SS316). Custom materials like Monel or Inconel are also available upon request.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 set. We support small batch orders and flexible customization for various project sizes.
