Component and body work
Mortise bodies, panels and mechanical parts are produced and finished in the cluster, which is what makes a non-standard body possible rather than a special order.

How the Plant Is Organised
Electronics assembly
Boards, readers, keypads and battery contacts are assembled and tested before the unit is closed, so a fault is found at the station rather than by the end user.
Assembly and testing
Units are assembled, function tested, battery tested and packing checked before the cartons are sealed.
Quality and inspection
Incoming material checks, in-process checks and a final function test, with third-party inspection welcome.
Packaging and marking
Colour boxes, manuals, master carton marking and shipping marks are prepared against an approved digital proof.
Export desk
Form E, invoice, packing list and B/L are issued here, and goods can be delivered to your forwarder warehouse in China.
The Nine Processes Behind Every Smart Lock
A smart lock is a mechanical product with electronics inside it. These are the nine stages that decide whether the body fits the door, whether the finish survives the climate and whether the batch matches the sample.
| Die casting | Zinc and aluminium bodies and panels are cast, which is what makes a non-standard body a production item rather than a special order. |
|---|---|
| Stamping | Sheet parts, brackets and reinforcement plates punched and formed to the drawing. |
| Drilling | Fixing holes, spindle bores and cut-outs positioned against the confirmed template. |
| Painting | Colour coats applied to the panels and covers, matched to the approved sample. |
| Baking | Cured in an oven so the coating hardness and the colour hold between batches. |
| Polishing | Surface preparation before coating, which is where the visible finish quality is decided. |
| Plating | Electroplated finishes for corrosion resistance, tested to ISO 9227 neutral salt spray. |
| Inspection | Incoming material, first article, in-process and final function checks, recorded per batch. |
| Packing | Packing checked against the approved proof, with photos sent before dispatch. |

Choosing the Right Finish
The finish decides what the lock looks like two or three years later, not what it looks like in the sample photo.

From Raw Material to the Carton
From incoming material to a sealed carton. Each stage has a record, which is what makes a batch traceable.
Incoming material
Components checked against the confirmed specification before they reach a line.
Machining
Drilling, tapping and cut-outs positioned against the drawing or the cut-out template.
Surface finishing
Painting, baking, polishing and plating, matched to the approved sample.
Electronics assembly
Boards, readers, keypads and battery contacts assembled, then tested before the shell closes.
Final assembly
Mechanism, panel and mortise body joined and function tested as a complete unit.
Inspection
Incoming, in-process, first article and final function checks, recorded per batch.
Packing
Packing checked against the approved proof, with photos sent before dispatch.
Buyer Questions
Buyer questions
Can we audit the production base?
Yes. Third-party inspection can be arranged at the factory before shipment, and a live video walkthrough can be booked at any time. Site area and monthly capacity are being confirmed with the production team before they are published.
Which processes do you run in house?
Body and panel work, surface finishing, electronics assembly, final assembly, functional testing and packing. Die casting, stamping, drilling, painting, baking, polishing and plating are detailed in the process list on this page.
How is the capacity allocated?
Trial orders are scheduled on the same line as bulk production rather than after it, so a small first order does not wait behind a container.
How do you keep batch tolerances stable?
An incoming material check, a first article check against the drawing and an in-process check before the unit is closed. A body produced to the wrong size cannot be reworked, which is why the measurement is confirmed first.
Can you produce a non-standard body or panel?
Yes. Non-standard mortise length, stainless versions, panel sizes and finishes are engineered from your drawing and sampled before the production run.
What experience does the team have?
The company was registered on 17 February 2016 and the team's lock-making experience goes back to 2013 in the Wenzhou lock cluster.
