OEM / ODM · Manufacturing · Quality

One partner from drawing to inspected shipment.

OEM and ODM programmes, in-house tooling, moulding, silicone, SMT and assembly — with one quality system across every gate.

Engagement models

Start with your design, or with ours.

Both routes state the boundary in writing: what stays yours, what we take over, before any tool is cut.

OEM / Build to print

Your design, our process.

Your design, our process. Hand us the 3D, the 2D drawing and the BOM and we can schedule; we suggest structural changes but never touch who owns the design.

Your enclosure Your key map Your BOM

ODM / Platform

Proven platform, your brand.

Proven platform, your brand. The enclosure and board tools are already cut — no new mould cost or lead time, only legends and firmware change.

Six disciplines

What we do in the building.

Six disciplines, none outsourced, keep lead times and change feedback short; only raw material, standard parts and finishing leave the building.

01

Tool room

We cut and repair enclosure and keypad tools ourselves, so a mould change never waits for an outside tool shop.

  • Tools cut from 3D and BOM, with first-article report
  • Mould changes machined in-house
  • Tool ownership stated in the contract
02

Injection moulding

ABS, PC, PC+ABS and TPU two-shot parts, with moulding parameters recorded per batch.

  • Moulding parameters archived and traceable
  • Two-shot and multi-cavity parts
  • First-batch samples kept for comparison
03

Silicone line

Silicone keypads and gaskets pressed in-house, with conductive pills placed exactly where the drawing calls for them.

  • Silk print, spray coating and laser etching
  • Conductive carbon pills and traces
  • Tactile feel and life-cycle spot checks
04

SMT & test

Placement, reflow, firmware flashing and burn-in, with the test fixture built alongside the board.

  • Fixture and firmware delivered with the batch
  • Flashing log kept per serial number
  • Functional and burn-in sampling
05

Assembly

Final assembly, nameplates and packaging, shipped to the customer's carton and label rules.

  • Customer label and carton specification
  • Accessories and warranty card included
  • First article approved by both sides
06

Quality lab

Dimensional, visual and functional criteria, signed off batch by batch before shipment.

  • Acceptance criteria issued from the drawing and shipped with the report
  • RoHS / REACH material declarations
  • Non-conformance closure records

The floor

A small factory with a short feedback loop.

The shop floor is in Humen, with moulding, silicone, SMT and assembly side by side. Samples are adjusted on the line itself, so a change goes back to the sample room the same day — that is what lets us quote 4–6 weeks to samples and 8–10 weeks to volume.

12 years Remote & silicone production

Reflow soldering

Two shifts on the SMT line, reflow profiles logged per batch.

Assembly

Assembly and test on the same line, results ship with the goods.

Quality gates

Nothing reaches the pallet unchecked.

Four gates, four records, all shipped with the goods; a failure at any gate stops the batch before it.

GATE 01

Incoming inspection

Check part number, lot and material declaration against the BOM; reject non-conforming incoming goods immediately.

GATE 02

First article

Compare the first article with the drawing and the retained sample; volume starts only after customer approval.

GATE 03

In process

Patrol the line on a sampling plan; a drifting parameter stops the machine on the spot, with the adjustment logged.

GATE 04

Final

Function, appearance and packaging sampled on finished units; the report ships with them.

Commercial terms

Questions that should be answered in writing.

Ask for a quotation →

These four come up in almost every enquiry. Everything else we answer per project, never from a template.

What is the minimum order quantity?

A new-tooling programme usually starts at 1,000–3,000 units; platform projects can go as low as 500. The exact number is stated in the quotation, per material and per process — we do not estimate it verbally.

Which is faster, OEM or ODM?

ODM is faster: the enclosure and board tools already exist, so only print, colour and firmware change, and samples usually take half the OEM time. OEM adds a tooling and first-article round.

Who owns the tooling?

Paid for, and the tool is yours: the contract lists it, states where it is kept and on what terms it moves. Until the tooling is paid in full it stays in our plant and is used against orders only.

Can we sign an NDA first?

Yes. Our mutual template is ready to sign, and yours is fine too. We sign before any drawing arrives, and drawings never sit on a shared drive.

Start with the five points. We will ask for the rest.

Use case, volume, target price, delivery date and certifications — send those five and within 48 hours you get a quotable offer, or an honest no.
