Do you sign NDAs to protect my intellectual property and mold ownership?

Yes, strictly. We sign comprehensive NDAs before reviewing drawings. All molds and designs remain your exclusive property, and we never share your data with third parties.

Is CNC machining and surface finishing done in-house or outsourced?

We offer a true One-Stop Solution. All secondary processes, including 3/5-axis CNC machining (in-house) and surface treatments (powder coating, anodizing, painting) (outsourced from contracted supplied), for better quality control and faster turnaround.

What is your Minimum Order Quantity (MOQ) for trial orders?

While our standard mass production MOQ is 500-1,000 pieces, we accept trial orders as low as 100 pieces to help you validate your design and market fit before committing to larger volumes.

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:Are you IATF 16949 certified, and can you provide full PPAP documentation?

Yes. We are fully IATF 16949 certified and provide complete PPAP Level 3 packages (including PFMEA, Control Plans, MSA, and SPC) to ensure full traceability and compliance for automotive and industrial projects.

Q:What is your quality control process, and what yield rate do you guarantee?

We guarantee a production yield rate over 98%. Our QC includes raw material spectrometer analysis, real-time casting monitoring, and 100% dimensional inspection via CMM. Optional X-ray and leak testing are available for critical parts.

Q:Do you provide free DFM (Design for Manufacturing) analysis before mold making?

Absolutely. We offer free DFM analysis using Moldflow simulation to optimize wall thickness, gating, and cooling. This prevents defects and reduces costs before any tooling begins.

Q:What are your lead times for mold fabrication and sample delivery?

Mold fabrication typically takes 30-45 days depending on complexity. Once the mold is ready, we deliver first-article samples within 7-10 days for your validation.

Q:What machine tonnage do you have, and can you handle both prototyping and mass production?

Our facility houses 280T to 900T machines. We support low-volume prototyping (MOQ starting at 100 pcs) and seamlessly scale up to high-volume mass production as your demand grows.
