Contact Us

Contact Us — Send a drawing and the response comes back with the certificate. Tolerances: ±0.002 mm turning, ±0.003 mm milling — ISO 9001 / IATF 16949 verified.

Before you commit, assemble the compliance file. Send a drawing and the response comes back with the certificate numbers, scope details, and documentation, so the supplier you choose is one you have verified, not one you are hoping for.

How do you request a certification and compliance review?

Send your STEP, IGES, or 2D drawing to [email protected]. The response includes a design-for-manufacturing review plus the certificate numbers, scope details, and documentation you need for your due-diligence file. Compliance is assembled in writing, before you commit anything.

Who is the contact person?

Felipe Iglesias handles inquiries at [email protected] and +86 13126536955, working in English, Portuguese, Spanish, French, and Chinese. Certification and compliance questions can be raised directly in the language you prefer, without a translation layer blurring the details.

Where is the factory located?

The facility is at No. 8, Shuibian Songyuan Road, Hengli Town, Dongguan, Guangdong, China 523470. A factory visit is welcome, and a live video walk of the floor and inspection room is available for buyers who cannot travel — the point is to let you verify the system behind the certificates yourself.

What documentation can you request before committing?

Before any commitment, request the certificate numbers (verified with the registrar, URS), the scope statements (read for exclusions like Clause 8.3), the legal registration (Dongguan Zhuohang Ltd, 91441900MA4UWT6X39), material certificates with XRF verification, CMM reports, and APQP/PPAP evidence where your program requires it. A supplier that withholds any of these is signaling a gap you should not accept.

What should you include when you request a quote?

A complete package removes the clarification loops that slow both the quote and the compliance file. Include a 3D model (STEP, IGES, or STP), a toleranced 2D drawing (DWG, DXF, or PDF), the material grade, the quantity, and any compliance requirements — material certs, PPAP, inspection reports. The more you specify up front, the more the returned file matches your actual program.

How does the first article verify both part and compliance?

With an MOQ of 1 piece, a first article arrives with its material cert, CMM report, and SPC chart. That single-part order verifies two things at once: that the part matches your print, and that the documentation system produces its evidence on schedule. Compliance confirmed on one part is compliance you can trust at scale.

What happens after you send the drawing?

The response sequence assembles your file in order. First, the DFM review flags anything that affects manufacturability or cost. Second, the certificate numbers and scopes are provided for your verification. Third, the documentation — material, inspection, SPC — is gathered against your specific requirements. Only then does the quote arrive, with its compliance assumptions stated, so you can close the file and the order together.

Assemble your compliance file on this supplier.
