    Send your 2D or 3D files, preferred materials, order quantities and target delivery date.

  2. 2. Review & sample

    Align on the manufacturing approach, tooling and inspection requirements. Review samples before production.

  3. 3. Move into production

    Coordinate manufacturing, quality checks and delivery with our team.

Good questions.

What should I send for a quotation?

Share your drawings, material, finish, estimated quantity and delivery requirements. Include critical dimensions and inspection criteria. If you are still developing the design, tell us what information is available.

Which materials can you work with?

Our capabilities include aluminum, stainless steel, brass and engineered plastics such as ABS, PC and POM. We review material suitability with you for the specific part and process.

How is product quality checked?

Inspection includes incoming materials, in-process checks and final inspection. Discuss dimensional reports, acceptance criteria and any third-party inspection requirements with our team.

What is the lead time from mold deposit to first shipment?

After your mold deposit clears, you receive a DFM report within 7 business days. Mold building takes about 50 days, with a T1 trial roughly 3 days after completion and samples couriered within 5 days of sign-off. You get a written timeline before deposit — no vague estimates.

Can you work from or modify an existing mold?

Yes. Our 22-person in-house tooling team uses CNC, EDM and laser welding to adjust or repair existing molds on-site — minor changes typically within 24–48 hours. Any adjustment work is quoted transparently before we begin.

How do you ship from Vietnam?

We ship FOB from Ho Chi Minh City and work with international freight partners, including alternative terminals and overland routing to Haiphong when port congestion requires it. Landed-cost breakdowns covering freight and customs are available with your quote.

Can you support OEM and ODM projects?

Yes. Share your requirements so we can discuss design support, tooling, sample development and a production plan appropriate for your project.
