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 your electrodes?

Our back-casting technology achieves a bonding strength of up to 127MPa, significantly higher than the traditional brazing method which is less than 100MPa.

Q:Which spray gun models are compatible with your products?

Our products are compatible with F4, 9M, and SG-100 spray guns from major brands including Metco, GTV, FST, AMT AG, and Praxair.

Q:Do you offer customization services?

Yes, we provide full customization based on customer samples, drawings, or designs, including semi-finished products with seamless tungsten-copper combinations.

Q:What materials are available for the tungsten electrodes?

We offer Lanthanum, Cerium, and Thorium tungsten materials, each selected for specific arc starting performance and ablation resistance.

Q:What is your policy on product defects?

If any defects due to our cause are found, we will replace the products for free and ship them with your next order.
