We source hermetic seals, feedthroughs and electronic packaging from specialised manufacturers in China — and carry the qualification, the documentation and the payment route as one accountable party.
We reply to technical enquiries within 1–3 working days. We are not the manufacturer.
Nobody orders these out of a catalogue. Every one of them starts as a drawing — and the drawing moves before anything gets made.
Pin count, glass type, plating, expansion match, the pressure the body has to hold. These get decided between your engineer and someone on a factory floor who shares neither a language, a time zone, nor a drafting standard with them.
These manufacturers are small, highly specialised, and mostly without an English website or an export desk. That part is real. It is also not the hard part any more — finding one takes an afternoon. Getting a drawing through revision after revision without quietly losing a tolerance is a different job, and it is the one that actually fails.
Somebody has to raise it, in the right words, to the person who can change it. Somebody has to still be there for the batch after that one. Not an agent who forwards the email and adds a margin to the reply.
Buyers who have already found their manufacturer still end up building this layer themselves. That is not a problem anyone solves with a search engine.
Not catalogue items. Pin count, material, pressure rating and package geometry all move to fit the design. The two blocks below sit on different axes — one is measured in volts, amps and bar; the other in gigahertz, leak rate and thermal conductivity.
The question is usually not “can someone make a terminal?”. It is whether the drawing, pressure duty, conductor layout and test route survive translation into a factory process.
Typical uses: refrigeration and CO2 systems, energy storage, electric traction, process instrumentation.
Here the trust problem shifts from metalwork to interface discipline: leak rate, thermal path, plating stack, optical window, pin layout and how the package will be handled after sealing.
Typical uses: optical communication, sensing, medical devices, commercial lasers, automotive electronics.
We do not work on defence, radar, satellite or airborne applications.
That rule is why some families in a supplier's catalogue will never appear on this page.
We read the drawing first and ask the questions that change the quotation — the ones about expansion match, plating stack, seal method and what "or equivalent" is allowed to mean. A manufacturer quoting against an ambiguity will quote the cheapest reading of it.
We identify and screen manufacturers who do not advertise, and we start every relationship at small volume so that a problem stays small.
We raise it, in Chinese, to the person on that floor who can change it — and we are still on it for the batch after. We own the paper trail, not the metallurgy. Where that line sits is written out below, and we would rather you read it now than find it later.
One consistent export document set, issued by one accountable party, so your own compliance people are not reconciling three versions of the same shipment.
You pay us. We pay the manufacturer after you pay us. One counterparty, one contract, one bank relationship.
One programme is running on exactly this structure right now: six part numbers. The factory redrew every drawing, the customer signed each one back, and nothing runs until that signature is in. We do not name customers. If that costs us a page of case studies, it is the right trade.
Not a specification. Just the situation. Two ways in — pick whichever is less work for you.
Seven short questions. No specification needed.
This desk asks questions — it does not quote, and it does not confirm what can be built. That comes back from us, in writing, after we have talked to a manufacturer. Nothing leaves your browser until you press send.
Most engineers prefer this. So do we.
