What materials are used for the electrodes?

We produce electrodes using Lanthanum tungsten, Cerium tungsten, and Thorium tungsten to ensure excellent arc starting and ablation resistance.

How does your back-casting technology compare to brazing?

Back-casting achieves a seamless bond with strength up to 127MPa, whereas traditional brazing is less than 100MPa and prone to cracks under high pressure.

What are the available nozzle sizes?

We offer F4 nozzles with diameters of 5mm, 6mm, 7mm, and 8mm.

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.
