Our dedicated QC engineers -- not the factory's own staff -- physically attend production and final inspection. A factory checking its own output is a conflict of interest. We eliminate that by acting as an independent layer between production and shipment.

Every shipment is accompanied by a Material Test Certificate (MTC) from spectrometer analysis, a dimensional FQC report matched to your drawings, and photographic loading records. These are not optional add-ons -- they are standard deliverables.

We specify and lock the alloy composition (High-Cr, Mn Steel, etc.) before production begins. Spectrometer readings are taken from heat samples, and Brinell hardness is verified from cut sections -- not just surface measurements.

Non-conforming product is held at factory. We issue a formal NCR (Non-Conformance Report), coordinate rework or reproduction with the manufacturer, and re-inspect before any container is loaded. Nothing ships until it passes.

Yes. DDP is our default offering for customers who want a single landed cost with no customs surprises. We handle export clearance, ocean or air freight, destination customs, and final delivery to your warehouse or site.

Machined and precision surfaces receive VCI (Vapor Corrosion Inhibitor) anti-rust film and moisture-absorbing desiccants inside sealed packaging. Container loading is documented and lashing methods are selected based on part geometry and voyage duration.

Yes. For project-based orders, we coordinate split deliveries aligned with your installation or commissioning schedule. Each partial shipment is inspected and documented independently, maintaining full traceability across all tranches.

Standard wear parts with confirmed drawings typically require 25-45 days production plus transit time. Custom castings or complex machined assemblies depend on process steps. We build a project timeline at quotation stage and track milestones against it.

DFM (Design for Manufacturability) review is a standard part of our intake process -- not an upsell. Our in-house engineers assess your CAD or 2D drawings for tolerance feasibility, casting geometry, machining sequence, and material suitability before we quote.

Yes. We work from physical samples, worn-out parts, or reference photos. Our team measures, reverse-engineers, and creates production drawings. You approve the drawing before any tooling or casting begins -- keeping you in full control of the specification.

You communicate requirements to us in English. We translate all technical specifications into factory-readable documents in Chinese, add unambiguous inspection criteria, and confirm alignment with the manufacturer before production starts. You are never talking to a factory through a language barrier.

We sign a mutual NDA before receiving any technical documents. Drawings are shared with manufacturers only on a need-to-know basis and under confidentiality obligations. We do not cross-source your designs to competing buyers or disclose your specifications to third parties.
