AI-Powered supplier vetting

SummaryNingbo Beilun Jiawei Machinery Co., Ltd. is identified primarily as a private Chinese manufacturer/factory in Ningbo, Zhejiang, with business activities covering non-ferrous metal casting, mold production, mechanical-part processing, hardware, plastic-product, metal-material, and auto-part products. The supplier demonstrates customization, ODM, and OEM capabilities, including customization from samples, designs, and full specifications, and reports new products within the past year. Production evidence includes six production lines, but the factory does not continuously reconcile quantities for each batch or mass-production order. Written procedures and records exist for supplier-service assessment, corrective and preventive actions, and customer complaints. Overseas-service infrastructure is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported. Financial information is represented only by reporting years, without sufficient evidence to assess...

Supplier typeThe supplier is identified as a Manufacturer/Factory and private owner in China, while another record describes the company nature as a trading company and its type as Combined. Its stated business scope includes casting, mold manufacturing, mechanical-part processing, and hardware-related manufacturing and sales, indicating a mixed manufacturing and trading structure.

After-Sales capabilityThe supplier has written procedures and records for service-capability assessment, corrective and preventive actions, and handling customer complaints. However, it reports no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and the stated number of countries offering overseas services is zero, indicating documented service processes but limited overseas service coverage.

R&D capabilityThe supplier reports new products within the past year and provides ODM services, demonstrating product-development activity. It also reports no available SDK, but SDK availability is not sufficient by itself to negate the broader evidence of R&D and ODM capability.

Production capacityThe supplier is identified as a factory with six production lines, and its business scope includes casting, mold manufacturing, mechanical-part processing, and hardware-product manufacturing. A stated weakness is that the factory does not continuously reconcile quantities for every batch or mass-production order, which may affect production-control reliability.

Customization capabilityThe supplier explicitly provides customization from samples, full customization, and customization from customer designs. It also reports ODM availability, giving direct evidence of broad customization and original-design manufacturing capability.

Client casesThe supplier reports providing OEM services to well-known brands, which is direct evidence of at least one type of customer experience. However, no customer names, products, project details, or verifiable case records are supplied, so the breadth and strength of its customer portfolio cannot be established.

Product Q&A

Q:What services do you offer?

We provide a comprehensive one-stop solution for high-pressure aluminum die casting, encompassing tool engineering, Design for Manufacturability (DFM) analysis, high-pressure die casting, precision CNC machining, surface finishing (e.g., powder coating, anodizing), component assembly, and packing/shipping. Our integrated process ensures seamless production from prototype to mass production .

Q:What`s your standards on tolerances?

For Casting, the general tolerance: ISO8062-3-DCTG5-DCTG3; For machining,the general tolerance:ISO2768-mK

Q:What is your MOQ?

We impose No Minimum Order Quantity (MOQ) and welcome projects with flexible volumes, especially to support new projects in their growth phase. Our production flexibility allows us to accommodate both low-volume prototyping and high-volume mass production.

Q:What is your Quality Control?

As an IATF 16949 certified manufacturer, our quality control integrates real-time monitoring of 200+ process parameters per cycle. We employ X-ray inspection, CMM (Coordinate Measuring Machine) for dimensional accuracy, and CT scannin to detect internal flaws as small as 15 microns. This ensures consistent output with defect rates below 0.8 parts per millio.

Q:What is your payment term?

- Tooling/Mold Cost: 50% deposit, with the balance payable after sample approval. - Bulk Production Orders: 30% deposit, with the balance payment terms negotiable upon order confirmation.
