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:Are these SG100 cathodes fully interchangeable with original Praxair TAFA parts?

Yes. Our SG100 plasma cathodes are manufactured strictly adhering to the original equipment dimensions and industrial tolerances, ensuring a 100% flawless drop-in fit and uncompromised performance.

Q:How do your cathodes prevent tungsten separation during high-power spraying?

We employ advanced diffuse welding under vacuum conditions. This high-tech process eliminates any microscopic air gaps between the tungsten insert and the copper base, guaranteeing optimal cooling water efficiency and preventing tip detachment or cracking under high-current loads

Q:What is the benefit of your cathode's precision concentricity?

Exceptional concentricity ensures the cathode sits exactly in the center of the SG100 gas distributor and anode. This creates a balanced, non-deviated plasma flame, resulting in uniform powder melting, less nozzle inner wall wear, and predictable coating thickness.

Q:Do you offer both the SG100 anode and cathode as a matching kit?

Yes, we provide full consumable kits for SG-100 systems (Anode + Cathode + Gas Distributor). Replacing the anode and cathode simultaneously is highly recommended to achieve the best arc stability and the lowest operating cost per spraying hour.
