The certificate PDF is linked on this page — it is a real document you can download and check with SGS, not a badge image.

Minimum feature size is 0.5 mm, and minimum wall is 0.8 mm in metals and 1.5 mm in plastics. The achievable limit is not one number for every feature, so send the drawing and we will say yes or no on the features that matter before you order.”}},{“@type”:”Question”,”name”:”Do you sign an NDA?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:”Yes.

The factory

You can watch your parts being made.

Your order runs on the machines in this aisle, in plants we own and staff — not in a broker's inbox. Tell us a date and we will walk you through the machine shop, the metrology room and the dispatch area, so that the factory on your shipping documents is a place you have actually stood in.

Inside the shop

The equipment your order will run on

Nothing here is stock photography or a render — these are our machines, our metrology room, our benches and our people, photographed in Bao'an. Send us the drawing and we will tell you which of them your part will run on, and what that means for your tolerance and your delivery date.

Before you order

The four questions buyers ask before the first PO

These are the four things that actually stop a purchase order — not price, usually. Each answer below links to the evidence, so you can judge it yourself instead of taking our word for it.

01IDENTITY

Is there a real factory behind this, or a broker?

Both plants are ours, in Bao’an District, Shenzhen — the address on your shipping documents is the address where your parts get cut. Come and stand in the workshop before you commit to anything, or ask us for a dated walkthrough of the bay your order will run in.
