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 F4 cathode?

The unique back-casting process achieves a bond strength of up to 127 MPa, which is significantly higher than traditional brazing methods (<100 MPa).

Q:Which plasma spray guns are compatible with this cathode?

It is compatible with F4, 9M, and SG-100 models from brands like Metco, GTV, FST, AMT AG, and Praxair, requiring no additional parameter adjustments.

Q:What materials are used for the tungsten insert?

We offer Lanthanum tungsten, Cerium tungsten, and Thorium tungsten alloys, allowing customers to choose based on their specific application needs.

Q:How does the back-casting process improve performance?

It creates a seamless metallurgical bond between tungsten and copper, providing better thermal conductivity, uniform heat dissipation, and preventing thermal stress cracking.

Q:What is the warranty or after-sales policy for defects?

We guarantee seamless bonding and concentricity. If any defect is found due to our cause, we will replace the product for free and send it with the next shipment.
