matches different partners according to categories and processes while maintaining unified business interfaces and quality requirements. It is especially suitable for multi-category, non-standard parts and cross-border procurement.
consolidates and manages demands from multiple categories, specifications and suppliers, reducing repeated inquiries, payments and logistics.
Convert drawings, samples and working condition requirements, coordinate DFM, mold, proofing, confirmation and batch nodes.
Select partners based on materials, processes, quantities and delivery dates, and continuously track plans and exceptions.
Conduct pre-shipment inspection based on confirmed items, and summarize size, material or inspection documents.
Coordinate labels, protective packaging, crating, documents and international logistics interfaces.
Keep confirmed versions and problem records, and continue to optimize the consistency and efficiency of subsequent batches.
Comparison of cooperation models
When the product is single and standardized, direct procurement may be sufficient; when categories, customization and cross-border links increase, unified management is more valuable.
| Key matters | Connect with multiple factories respectively | is coordinated by Longtouwang |

FAQ
We select long-term cooperative manufacturers based on categories, and manage the results by confirming samples, drawing versions, inspection lists and pre-shipment acceptance. The depth of inspection for different orders will be determined based on risk and customer requirements. Can
OK. We will first evaluate the sample completeness, surveying feasibility and key working conditions. For parameters that affect function but cannot be judged from samples, you will be asked to confirm before quoting.
The minimum order quantity depends on the material, mold, process and partner. Standard parts are usually more flexible, and mold parts need to be calculated based on mold cost and single production efficiency.
can coordinate material certification, dimensional records, or third-party testing on a project-by-project basis. Please indicate the standard, project and document language during the inquiry stage.
When time and transportation conditions permit, container consolidation or centralized shipment can be coordinated to reduce cross-border logistics links.
We will jointly analyze the reasons based on confirmation standards, batch information, pictures or samples, and coordinate replenishment, rework or other reasonable solutions with our partners.
