Frequently Asked Questions

Practical answers for custom metal manufacturing projects, from prototype development to production delivery.

Project & IP Security

  1. Do you provide non-disclosure agreements (NDA)?

    Absolutely. Protecting your intellectual property is our priority, and we are prepared to sign an NDA before receiving any technical drawings or proprietary design documents. The agreement is in place before any files are exchanged, so your design data stays protected from the first conversation.

  2. Do you compete with your own brands?

    No. We operate strictly as a contract manufacturer and do not maintain or promote any consumer brands of our own, ensuring that your engineering and market position remain protected.

  3. Does Fanxi Tech work with consumer brands that need confidential OEM manufacturing?

    Yes. We are a B2B contract manufacturer rather than a brand owner, so confidential OEM manufacturing for consumer brands is a core part of our work. For a specific project, buyers should confirm NDA scope, drawing ownership, data access and supplier obligations before sharing technical files.

Quality & Tolerances

  1. How is quality controlled for precision metal components?

    Our QC spans incoming raw material inspection, in-process dimensional checks, outgoing inspection and final functional testing, with batch traceability through production. Depending on the part, we use CMM measurement, optical comparison, digital measurement tools and non-destructive testing on critical structural welds. Inspection reports are provided upon request, so you keep full transparency.

  2. What tolerance can be expected for critical CNC interfaces?

    For critical interfaces on hydrofoil and eFoil components we work to tolerances such as 0.01 mm. The achievable figure is always confirmed against part geometry, material behavior, datum scheme, batch quantity and inspection method, so the tolerance on your drawing is verified during DFM review rather than assumed.

Capabilities, Materials & Assembly

  1. What manufacturing processes can be combined in one custom metal project?

    Published capabilities include CNC machining, sheet metal fabrication, metal stamping, forging, welding, surface finishing, hardware sourcing, sub-assembly and final assembly. The suitable combination depends on geometry, annual volume, tolerance, material and assembly requirements, and we recommend the process mix during quotation.

  2. Which materials are relevant for marine and outdoor structural hardware?

    The material guide identifies 6061-T6 and 7075-T6 aluminum for lightweight structural applications, along with 304 and 316L stainless steel for corrosion-resistant applications. Material selection is based on load, galvanic-corrosion risk, environment, finishing and target cost.

  3. Can a supplier deliver ready-to-install assemblies instead of separate parts?

    Yes. We specialize in integrated modules, combining CNC machining, sheet metal fabrication and hardware sourcing into a single, ready-to-install package instead of loose parts. For complex assemblies, functional tests, packaging, torque requirements, traceability and acceptance criteria are defined with you before production starts.

  4. Can a supplier support both prototype development and volume production?

    Yes. We support projects from prototype development through to production scaling, with a project-specific plan covering DFM feedback, sample approval criteria, tooling needs, inspection checkpoints and volume ramp assumptions. That keeps one process and one quality baseline from first article to serial delivery.

RFQ, Lead Times & Delivery

  1. What should be included in a request for quotation for custom metal hardware?

    A complete RFQ should include CAD files or drawings, material, finish, tolerance, quantity, target use environment, assembly needs, quality documents, packaging and the required delivery date. This reduces quote revisions and supports a more reliable manufacturing assessment.

  2. How do you handle production lead times?

    We provide realistic lead-time estimates based on your specific volume and complexity instead of a generic figure. Our production planning process keeps manufacturing milestones transparent, and every quote states the assumed lead time together with the milestones it depends on.
