01 / Overview
An asset-light, design-driven supply model. What is delivered is project certainty -- not a factory.
Yuchuang coordinates cooperative production through design review, supplier organisation and quality control.
Production drawings are reviewed before manufacture. Finished goods are consolidated for inspection, then numbered, packed and loaded with unified project traceability.
02 / Supply model
Integrator, not manufacturer.
Yuchuang operates no owned or controlled factory. Production is completed entirely by a small set of cooperative suppliers under Yuchuang review.
No owned factory
No owned or controlled production facility. The role is design, organisation, review and control.
3-4 cooperative suppliers
A concentrated supplier group, with one core supplier, organised by category capability and price.
Category-based division
Orders may be split across suppliers by capability and price, then unified by Yuchuang control.
03 / Workflow
From drawing to container.
Each step resolves into a controlled state: deepened, reviewed, inspected, numbered and loaded.
Supplier deepening & self-inspection
Suppliers complete production deepening and self-inspection before submitting production drawings.
Yuchuang review
The design lead reviews production drawings; follow-up unifies numbering, version, colour, quantity, interface and delivery.
Centralized inspection
Finished goods from multiple suppliers are consolidated to a single location for inspection before packing.
Step 04 / Inspection method
Sampling for standard items
Standard products are checked by sampling against reference and packing lists.
Piece-by-piece for non-standard
Non-standard products are inspected piece by piece for size, colour, cut-outs and interfaces.
Numbering, traceability & container loading
Products, packaging and installation materials use a unified numbering scheme, then are loaded into containers.
04 / Inspection record
What is verified before packing.
Every consignment resolves into an inspectable, numbered state before release.
