Who is your point of contact?

Felipe Iglesias is the business development director and the person you will correspond with from first drawing to final delivery. He works in English, Portuguese, Spanish, French, and Chinese, so you are not forced through a translator for technical questions.

Reach him at [email protected] or +86 13126536955. One contact, start to finish — no hand-off between a sales rep and an engineer that loses the thread of your part.

What should you send to get a DFM review and quote?

You do not need a finished production drawing to start. Send what you have, and the review will tell you what else matters.

Send these to [email protected]. You get back a design review and a quote, usually within one business day.

What happens on a factory visit?

A visit is the strongest verification there is, and it costs you nothing but the trip. When you come, you walk the floor that will machine your parts and see the evidence behind the claims:

Bring a drawing. We will walk you through how the part would be machined and what the design review would flag — a live DFM session, before you commit a single dollar.

What should you prepare before a visit or a first email?

The more complete your first message, the more useful the first reply. A little preparation turns a vague inquiry into a concrete quote.

If you are visiting from overseas, email ahead and we will coordinate the timing so the right people are on the floor when you arrive.

How do you stay connected after the first order?

A machining relationship is built on repeat work and documentation, not a single transaction. After the first order, you get the same contact, the same traceability, and the same quarterly reviews that turn a vendor into a supply base.
