For engineers with a finished CAD file

Your drawing gets read by an engineer before you get a price

Send your file to our engineering team, not a quote form. They review it for manufacturability, flag anything that won't machine well, and price what you actually drew.

  • An engineer checks tolerance, wall thickness, and tooling access before pricing, not after your first batch fails
  • One team, from your first email to the day it ships
  • Ask for an NDA before you send anything, if you need one
  • No MOQ. Start with a single sample if you're not ready for a production order
  • Custom CNC parts in as fast as 15 days

Who you're talking to

One Team, Start to Finish

Our engineering team reviews your drawing, prices it, and stays on your order through production and shipping. You're not handed to a new contact at each stage, and you're not filing a support ticket when something needs a second look.

We're the ones who answer when you email a drawing or send a message on WhatsApp. Not a shared sales inbox monitored by whoever's free.

Why Shenghao

What working with us actually looks like

An automated quoting tool prices whatever you upload without anyone reading it. Ours doesn't work that way. Tap or hover a card for the detail.

Engineering review

An engineer checks your part first

Every RFQ goes through a manufacturability review before pricing — tolerance issues, wall thickness, tooling access are flagged before you commit, not after the first batch fails.

Single point of contact

One team, start to finish

The person who quotes your part is the same person managing it through production and shipping — no hand-off, no re-explaining your spec to someone new.

Full-solution

Every process, one supplier

CNC, molding, sheet metal, casting, 3D printing and EDM under one system — you're not juggling five vendors and five sets of paperwork for one assembly.

Your CAD file

What happens to your drawing after you send it

The question every buyer has and most never ask out loud.

Who actually sees it

Your drawing goes to the engineer reviewing it for manufacturability, then to the machinists building your order. It doesn't get forwarded outside the people working on your part.

NDA before you send anything

If your drawing needs an NDA in place first, ask for one before you send the file. We'll sign it. We just don't send one unprompted, so ask if you need it.

Your design isn't reused

Your file is used to quote and build your order, not kept on file to reference for other customers' parts.

How it works

From drawing to shipped part in four steps

The same team stays with your part from quote to delivery.

1

Send your drawing

Email or WhatsApp your CAD file (STEP, IGES, SLDPRT or DXF), material, quantity, and deadline. No account, no quote-builder to guess at.

2

Manufacturability review

An engineer checks tolerance stack-up, wall thickness, and tooling access, and flags anything that won't machine as drawn.

3

Engineer-reviewed quote

Your price is based on the part as drawn, with any suggested changes noted separately. Not a number generated from your file size.

4

Build, inspect, ship

First article and final inspection against your print. Dimensional reports and traceability documentation ship with every order.

Not ready for a production order

Start with a sample run

No MOQ means no MOQ. Order a single part or a small batch to check fit, finish, and how we handle your file before you commit to volume. Same manufacturability review, same team as a production quote.

Certifications

ISO 9001, IATF 16949, ISO 13485, ISO 14001

Each certification unlocks a different class of buyer, not just a wall plaque. Full breakdown, plus our 4-step inspection process, on the Quality & Certifications page.

FAQ

Common questions

What's your minimum order quantity?

No MOQ. We quote single prototypes the same way we quote production runs, and scale with you from there.

Can I get an NDA before sending my drawing?

Yes. Ask for our NDA before you send anything and we'll get it signed first. We don't send one unprompted, so ask if you need it in place.

Who exactly will I be working with?

Our engineering team. They review your drawing, price it, and stay on your order through production and shipping, so you're not routed to a different contact at each stage.
