Sharing a Factory Without Sharing Your Design

TL;DR

Sharing a building with other brands does not mean sharing your design. In normal custom manufacturing the tooling fee buys the exclusive right to make parts from your mould, and your artwork and specification sit under your own purchase order rather than on a shared drive. A competitor at the same factory has no claim to your files. The controls that matter are contractual: an exclusivity clause, a named tool-ownership clause, and per-customer artwork storage released only against your PO. WINTEL supplies TF cards from 4GB to 256GB and UDP modules with tooling and artwork held separately per customer. Ask for the clauses in writing and the fear of leakage becomes a non-issue.

The fear is real, but the fix is contractual

Many buyers hesitate to place a custom order because the supplier also runs other brands. The worry is reasonable: if your competitor’s enclosure sits two benches away, what stops your logo walking over? The answer is that a factory is not a single shared project. It is a set of isolated production lots, each tied to its own purchase order, its own tool and its own artwork package. The leakage risk is real only when those boundaries are left unspecified.

Do not refuse a capable supplier on the fear alone. The cheaper mistake is skipping the clauses that keep your design yours. A good factory already separates customer assets as standard practice; your job is to make that practice contractual so it survives a change of sales contact or a busy quarter.

What the tooling fee actually purchases

Standard tooling practice draws a line that buyers miss. What a tooling fee usually buys is the exclusive right to have parts produced from that tool, not automatically the physical steel. The metal may stay the supplier’s asset, leased to your programme, or it may be yours to keep — the difference is a clause, not a default.

This matters for design privacy in two ways. First, exclusivity means no other buyer can order parts from your mould; the tool is reserved to your PO. Second, if you ever want the tool moved or returned, the ownership clause decides who carries it. A vague fee line leaves both questions open, and an open question is where a competitor’s enquiry finds a gap.

Tooling lead time sets the privacy window

The same tooling cycle that defines ownership also sets how long your design is in the shop before it is buried in production. Aluminium tooling runs 2–4 weeks from approved drawing to T1 samples; steel tooling runs 4–8 weeks; complex multi-cavity tools run 10–12 weeks. Simple engineering changes after T1 add 1–2 weeks, and a major change such as a side action adds 3–5 weeks.

During that window your drawings, your 3D files and your sample parts exist in the shop. The control is not to hide them — it is to tag them to your PO and your NDA so that anyone who opens the file sees it is owned, not free. A 10–12 week complex tool with no ownership clause is a 10–12 week exposure; the same tool with the clause is just a schedule.

Moving a tool is harder than moving a file

A subtle protection comes from the tool itself. Moving a tool to another factory needs a clear ownership clause and matched machine platen size and tonnage. A press that does not fit the platen cannot run the tool, so the physical asset is harder to redeploy than a digital file. That friction works in your favour: your mould cannot quietly appear on a different line without a deliberate, documented transfer.

If your contract names the platen size and tonnage, the tool is effectively pinned to the presses you approved. A supplier who wants to shift your production has to clear that with you first, because the alternative is a tool that does not fit. Design privacy, here, is partly a function of mechanical fit.

Artwork is the real exposure point

The mould holds your shape. Your logo and print layout hold your brand, and they pass through the print stage where exposure is highest. A pad-print, silk-screen or laser step pulls your artwork from a file, applies it, and generates proof prints. If that artwork lives in a shared library, anyone with access to the printer can see it.

The fix is procedural and simple. Store artwork per customer. Release it only against your own PO. Require proof prints to be destroyed or archived after the run, not left in a tray by the machine. One artwork package, one order, one approved batch — not a common folder. This is the control that actually stops a logo leaking, because it removes the moment where your file is open and unattended.

What to put in the contract

Four clauses turn a vague reassurance into a binding wall. First, an exclusivity clause stating no other buyer may order from your tool. Second, a tool-ownership clause naming who holds the steel and the platen size and tonnage it fits. Third, a per-customer artwork storage clause released only against your PO. Fourth, an NDA that covers drawings, samples and proof prints for the life of the programme, not just the first order.

Avoid a supplier who will only promise privacy by email. A clause you cannot point to is a clause that will not hold when a salesperson leaves. If a factory resists putting exclusivity in writing, that resistance is the signal, not the reassurance.

Where WINTEL fits

WINTEL supplies TF cards from 4GB to 256GB and UDP modules from 128MB to 128GB, with read/write speed specified per order. Tooling and artwork are held separately per customer and released against the matching purchase order. The TF card form factor is 15 × 11 × 1 mm at 0.25 g; the UDP module is 11.3 × 24.8 × 1.45 mm at 0.819 g. Both are built on tooling that is reserved to your programme, not shared across the floor.

Tell us what you need made and we will scope the tooling and the storage terms up front, in writing, before any steel is cut.

A short checklist before you approve tooling

Confirm the exclusivity clause is present and names your PO. Confirm the tool-ownership clause states who holds the steel. Confirm the platen size and tonnage so the tool cannot be silently moved. Confirm artwork is stored per customer and proof prints are archived after the run. Four confirmations, and the same-factory fear disappears.

Skip any one of them and you have left a door unlocked. The cost of the clause is a paragraph; the cost of the gap is your design on a competitor’s shelf.

Audit rights close the loop

A clause that reserves your tool and your files is strong; the right to verify it is stronger. Ask for audit rights that let you or a named inspector confirm the tool is stored under your PO and the artwork is not sitting in a shared library any other buyer can open. The supplier who agrees in writing has already built the separation the clause describes; the one who hedges is telling you where the gap will appear.

Audit rights also catch drift that a shipment alone will not show. A factory that respected your exclusivity in month one can loosen it under volume pressure in month nine, and you will not see that from a carton of finished goods. A clause you can exercise turns a promise into a check, and the check is what keeps your design yours across the whole life of the programme, not just the first order.
