Factory or trading company — six checks that settle it

Every supplier on every platform claims to be a factory. The claim is easy to test if you know which questions a trading company cannot answer. This page lists the six, and answers all six for ourselves — including the one where the answer is "not in-house".

The six checks

  1. Ask for a video of the moulding shop, not of the product. A trading company has product footage and renders. It does not have a machine running your part with a cycle counter visible.
  2. Ask who owns the mould. A factory owns its moulds and can tell you the mould number, when it was made and when it was last serviced. A trading company has to ask someone else.
  3. Ask which processes are in-house and which are subcontracted. Almost nobody does everything in-house. A supplier who says "all in-house" is either very large or not being straight with you.
  4. Look at the applicant name on the test report. FCC-ID and CE documentation name the manufacturer, not the seller. If that name is not the company you are talking to, you are talking to a reseller.
  5. Ask whether the quotation includes mould amortisation. A factory knows what its tooling cost and when it is paid off. A reseller's price is somebody else's price plus a margin.
  6. Compare the factory address with the business licence. Matching is not proof, but a mismatch needs an explanation.

Our answers to all six

CheckOur answer
1. Moulding shop footageAvailable. Our own moulding shop in Bao'an, Shenzhen, running the shell mould at a 43-second cycle, the lid at 37 seconds four-up and the earbud housing at 50 seconds four-up.
2. Mould ownershipOurs. Moulds are numbered and serviced on a maintenance schedule; a mould change for a different iPhone model is a scheduled activity, not an outsourced one.
3. In-house versus subcontractedIn-house: injection moulding, final assembly, app configuration and language pack loading. Subcontracted: vacuum electroplating and UV coating, carried out by a dedicated plating partner under our own colour standard with first-article approval each batch. Bought in: mainboard, drivers and batteries.
4. Test report applicantThe manufacturer named on the FCC-ID and CE documentation is the factory entity, not a trading arm. Certificate numbers released against a confirmed order.
5. Mould amortisation in the priceQuotations are built from moulding, plating, battery, mainboard and assembly cost. Tooling is a separate line when new tooling is required — which is exactly how you can tell it was priced rather than guessed.
6. Address consistencyBao'an District, Shenzhen, Guangdong. Factory visits by appointment — see below.
What we do not claim: we do not claim in-house plating, we do not claim an SMT line, and we do not claim overseas warehouses. The mainboard is a bought-in solution and the plating bath belongs to a partner. Both statements are less impressive than the alternative and both are true.

Why in-house moulding changes the answer on quality

The difference is not that in-house moulding is automatically better. It is that the feedback loop is shorter, and on this product three specific things depend on it:

Changeover speedSwitching a run from one iPhone model to another is a mould change we schedule ourselves. If the mould lives at a third party, your order waits for their schedule.
Colour consistencyThe plating is external, but the jigs and the colour standard are ours, and the first article of every batch is approved against that standard before the run continues. Without a controlled first article, four colours drift apart across batches.
Defect attributionWhen a shell is out of tolerance, the cause is either the mould, the machine or the plating. Owning two of the three means the question is resolved in-house instead of between suppliers.

One practical consequence: because we run the shell mould ourselves, cycle time is a known number rather than a claim — 43 seconds, single cavity, robot take-out. A supplier who cannot tell you their cycle time is not running the machine.

Shenzhen, Dongguan or Guangzhou

Buyers sourcing phone accessories in the Pearl River Delta usually compare these three, and the right answer depends on the product rather than on the city's reputation.

CityStrengthBest for
ShenzhenDensest concentration of mould making, injection moulding, plating and electronics in the region. Close to Yantian and Shekou ports and to the airport for air freight.Products with high part complexity, frequent model changes and short tooling cycles — which describes a phone case that has to follow seven iPhone generations.
DongguanLower labour and factory rents, larger floor plates, strong at high-volume standardised moulding.Long runs of one part with few changes, where cost per unit dominates over flexibility.
GuangzhouTrading and wholesale concentration, strong logistics and market access.Sourcing and consolidating many small items from many suppliers, rather than owning the manufacturing process.

The practical test: if your product changes every year because the phone changes every year, and the mould has to be modified or replaced, Shenzhen's density of tooling suppliers is what keeps the changeover short. If you are buying the same part in the same specification for three years, Dongguan's cost base wins.

FAQ

Frequently Asked Questions

Is TalkShell a manufacturer or a trading company?

A manufacturer. Injection moulding and final assembly are carried out in our own facility in Bao'an District, Shenzhen. Electroplating is subcontracted to a dedicated plating partner under our own colour standard, and the mainboard, drivers and batteries are bought in.

Is electroplating done in-house?

No. Vacuum electroplating and the UV top coat are carried out by a dedicated plating partner. The plating jigs and the colour tolerance are ours, and the first article of every batch is approved against our standard. We state this because a buyer inspecting the factory should know which building houses which process.

Do you have your own SMT line?

No. The mainboard is a bought-in solution rather than assembled in-house. Moulding, assembly, app configuration and packing are in-house.

Can I visit the factory in Shenzhen?

Yes, by appointment. You can see injection moulding, assembly, app configuration and packing on site. The plating line belongs to our partner and needs a separate arrangement, which we can organise if you tell us in advance.

Should I source phone accessories from Shenzhen or Dongguan?

Shenzhen for products with high part complexity and frequent model changes, because of the density of mould making and plating suppliers and the short tooling cycle. Dongguan for long runs of a standardised part where cost per unit dominates. Guangzhou for consolidating many small items across suppliers.

How can I tell a factory from a trading company?

Six checks: ask for moulding shop video rather than product video, ask who owns the mould, ask which processes are subcontracted, check the applicant name on the test report, ask whether the quotation includes mould amortisation, and compare the factory address with the business licence.
