Four things to put in the first email
We quote from the model, not from the catalog photo. The same shell often runs in three thicknesses, and the price follows the thickness. If you are bringing a new design, your drawing replaces the model number. The rest of the list still applies.
Request a quote
Send these four and nothing else is needed to start. If you only have two of them, send two and we ask for the rest.
- The model name, or a photo of the case you want matched
- Device model and the exact variant, for example iPhone 17 Pro
- Quantity in PCS, per color if the colors differ
- Destination port, so the freight can be quoted separately
The quote lists the unit price and the packing for that device. Terms are EXW Dongguan.
Order a sample
Samples ship from the same wall you see on the factory page. Tell us the model, the color and the address. Ask about the sample cost in the same message.
If the model you want is not on this site, send a photo or a link. The catalog is 42 models and 24 of them are not published here.
Book a visit or an audit
Half a day covers the mold shop, the injection floor, the lab and the sample room. They are within a five minute walk of each other.
For an audit, send the standard you audit against and the dates you have. We can tell you what we can open on those days, including the findings we are still closing.
OEM and ODM
OEM means the design is yours. A drawing, a 3D file or a sample is enough to quote from. We come back on wall thickness, draft, shut-off and the magnet pocket before any steel is cut.
ODM means you start from ours. The catalog holds 42 designs. Pick one and it runs with your logo, your color and your box. If a model is close but not right, we change the tool. A different shell means a new mold.
Say which of the two you are doing in the first message. It changes what we ask for next.
What we do with your email
We keep the message and the reply so the next person who answers knows the history. We do not sell the list and we do not add you to a newsletter. Ask us to delete the thread and we delete it. The full text is on the privacy page.
