Video Factory Tour

Flying to Wenzhou costs a week and a flight. A video call costs an hour. We walk the assembly and inspection area with you, answer questions live and show the stage your order is actually at.

The walkthrough video and the factory photography are being produced by the workshop team. Until they are published, the tour is run live on a call, which is more useful anyway because you can ask about your own model.

Video tour of the smart lock production line

What You See on the Call

Component and body work

Where mortise bodies, panels and mechanical parts are produced and finished.

Electronics assembly

Board assembly, reader and keypad fitting, and the check that happens before the unit is closed.

Function testing

The unlock, keypad, handle return and battery checks every unit goes through.

Packing line

Colour box, manual, carton marking and the packing photo stage.

Your order on the line

If your order is in production we show it, and send photos or a video afterwards.

Export desk

Where Form E, invoice, packing list and B/L are prepared, and where forwarder deliveries are booked.

Production Updates After the Order

Once an order is placed, updates follow the same logic as the tour: you see the stage rather than being told about it.

  • Specification and drawing confirmation in writing
  • Sample photos and a working video before the sample ships
  • Production photos at assembly and packing
  • Packing and shipping-mark photos before dispatch
  • Document copies sent ahead of the goods

PDF, JPG, PNG or DWG. A photo of the door edge with a ruler is usually enough to confirm the fit.

We reply within 12 working hours. Send a door drawing or a photo of your existing lock body and we will confirm the fit before production. File attachments up to 10 MB; if the upload does not go through, email the file to mike@bbdhome.com and quote your company name.

Buyer Questions

Buyer questions

Can we visit the factory in person?

Yes, by appointment. Most buyers start with a live video walkthrough because it takes an hour instead of a week, and then visit if the project size justifies it.

Can the tour focus on our own model?

Yes. Tell us the model or the specification before the call and we will walk that part of the line, including the stages your order is currently at.

What will we actually see?

Body and panel work, electronics assembly, the function and battery test stations, the packing line and the export desk where Form E, invoice, packing list and B/L are prepared.

Is the recorded walkthrough available?

The recorded video is being produced by the workshop team. Until it is published the tour runs live on a call, which lets you ask about your own model.

Do you send production updates after the order?

Yes. Sample photos and a working video before the sample ships, production photos at assembly and packing, and packing and shipping-mark photos before dispatch.

Next Step

If the answer you need is not here, ask us directly. We would rather answer a hard question before the order than after the goods land.
