AI-Powered supplier vetting

SummaryWeilai is explicitly identified as a professional technical supplier offering 3D software design and broad customization services. Its stated business scope covers new-material R&D, metal manufacturing, forging, powder metallurgy, nonferrous alloys, and technical services. The supplier reports CNC lathe, machining-center, and turning-center resources, inventory capability, documented finished-product inspection instructions, and self-operated import/export rights. Innovation-related evidence includes advanced R&D claims and collaboration with the CSU Powder Research Institute. However, no SDK is available, there is no valid manufacturing-capacity contract with related subcontractors, and no overseas warehouse, showroom, agent, or branch is reported. Evidence is insufficient for certification holding, after-sales service capability, financial credibility, and customer cases.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its business scope includes new-material technology R&D, metal-product manufacturing and sales, nonferrous alloy activities, and technical services, indicating a manufacturing-oriented technical supplier.

R&D capabilityEvidence supports professional technical R&D, 3D software design, flexible customization, advanced R&D positioning, and an Industry-University-Research collaboration with the CSU Powder Research Institute. However, the supplier explicitly has no available SDK, so innovation capability is supported generally but not across all technical interfaces.

Production capacityThe supplier lists CNC lathe, machining-center, and turning-center resources, relevant metal and powder-metallurgy manufacturing activities, inventory capability, and standardized written inspection instructions. A stated lack of a valid manufacturing-capacity contract with related subcontractors is a constraint, but the available evidence still explicitly demonstrates production resources.

Customization capabilityBoth slices explicitly report customization from samples, minor customization, full customization, customization from designs, and flexible customization, together with 3D software design services. This is direct evidence of broad customization capability.

Product Q&A

Q:What is the bonding strength of the electrode?

The bonding strength is more than 120MPa (or up to 130MPa in some descriptions), ensuring a complete seamless connection with no holes in the cross-section.

Q:How does the service life compare to general electrodes?

The service life is 5-10 times longer than general bonding methods due to the high density and uniform internal structure achieved by NDB technology.

Q:Can the electrode shape be customized?

Yes, the shape is available in straight configuration or can be customized as per customer request.

Q:What materials are used for the welding end and stick?

The welding end uses high-quality pure W, Mo, and their alloys. The stick is made of chrome copper or chrome zirconium copper for high conductivity and fast cooling.

Q:Do you perform quality checks on the products?

Yes, we perform 100% full inspection. Inspectors check every finished product one by one to ensure all parameters are met, discarding any unqualified products.
