Formal Quotation

• Timeline: 1–3 Business Days

• Action: Provision of a detailed, transparent pricing proposal, including tiered volume discounts and estimated shipping costs.

Rapid Prototyping

• Timeline: 5–15 Business Days

• Action: Development of single-cavity bridge tooling and functional prototypes for design validation (Fit-Form-Function) before committing to mass production.

Precision Tooling & Pilot Run

• Timeline: 20–35 Business Days

• Action: Fabrication of high-durability multi-cavity molds, followed by a pilot production run to calibrate tolerances and finalize process parameters.

Mass Production

• Timeline: Per Agreed Schedule

• Action: Scaled manufacturing executed under strict adherence to ISO standards, ensuring consistent cycle times and high-volume throughput.

QA/QC & Global Logistics

• Timeline: Ongoing / Final Dispatch

• Action: 100% final inspection and OQC (Outgoing Quality Control). Door-to-door delivery via DHL, FedEx, UPS. 

• Sea Freight: Major exports are handled through Hai Phong Port (HPH), the largest deep-sea port in Northern Vietnam, ensuring cost-effective and reliable container shipping to the USA, Canada, and the European Union.

• Air Freight: For urgent bids and rapid prototyping, we utilize Noi Bai International Airport (HAN) in Hanoi. Partnering with premium carriers like DHL, FedEx, and UPS, we guarantee lightning-fast door-to-door delivery.

• Compliance: All shipments are accompanied by comprehensive documentation—including Invoice, Packing List, COA, and CO (upon request)—ensuring seamless customs clearance at your destination.
