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 rated torch power and current for your F4 nozzles and electrodes?

Our F4 consumables are engineered specifically for standard 40kW to 55kW atmospheric plasma spraying (APS) systems. They are optimized to perform with excellent stability under standard working currents ranging from 400A to 700A and voltages between 50V and 80V, which are typical for classic F4 torch operations.

Q:Are these consumables 100% compatible with Oerlikon Metco and TPS F4 torches?

Yes, absolutely. All our F4 cathodes (electrodes) and anodes (nozzles) feature 100% dimensional interchangeability. They perfectly fit standard Oerlikon Metco F4-MB, F4-HB, F4-Vb torches, as well as the upgraded Swiss TPS F4-Pro series. You can install them directly without modifying the internal water distributor or gas ring.

Q:My F4 electrode experienced single-sided melting after only a short run. How can your products prevent this?

Early single-sided erosion or severe arcing is usually caused by poor concentricity or a failed internal water-seal. We use micro-level CNC precision machining to ensure absolute concentricity between the nozzle bore and the tungsten tip. This keeps the plasma arc perfectly centered. Additionally, we recommend your engineers check the internal O-ring alignment during assembly to avoid water bypass.

Q:What specific manufacturing process do you use to secure the tungsten insert inside the copper body?

We utilize advanced vacuum back-casting (seamless infiltration) bonding technology. This proprietary process guarantees a 100% void-free joint between the high-density tungsten core (thoriated or lanthanated tungsten) and the premium purple copper shank. It ensures that heat is instantly transferred to the cooling water, preventing the tungsten tip from overheating and melting.

Q:Can you customize the internal F4 nozzle bore diameter based on our coating recipes?

Yes, we support customized manufacturing based on your requirements. While we provide standard F4 nozzle bore diameters such as 6mm, 7mm, and 8mm, we can adjust the internal profile, compression angle, or length according to your technical drawings. Please send us your PDF or STEP drawings, and our technical team will provide a custom quote within 24 hours.
