From your first drawing to your next production run.
Choose the support your project needs: build-to-print prototyping, ODM design and manufacturing, or a continuous path from prototype to mass production.
We check it, confirm the materials and build samples to it.
See the service ↓Service 02 · ODM — Custom Design & ManufacturingYou have a requirement.We develop the design with you and our engineering partners, then build it.
See the service ↓Service 03 · Prototype-to-Mass ProductionYou need a production partner.We carry the design from prototype revisions through pilot builds to mass production.
See the service ↓Three ways of working, not a package bought in order. A prototype can be ordered on its own, and production support can start with a design you already hold. Whichever you choose, quantities can be small, materials are checked early, and you have one accountable contact for questions, changes and updates.
Build-to-Print Prototyping
“I have a drawing. I need it built.”
Turn your drawings, pinouts and BOM into physical samples for evaluation. We review the build requirements, confirm materials and manufacture to the agreed specification.
Who it is for
Teams that already hold a drawing, a pinout, a BOM or a clear specification and need it made: a first prototype, a replacement sample or a batch for testing.
What you can bring
- Assembly drawing or sketch, with lengths and tolerances
- Pinout or wiring list
- Connector and wire part numbers, or the BOM
- Quantity, test requirements and the date you need the samples by
What we take on
- Check the package for missing information and manufacturability before anything is built
- Confirm materials as exact part numbers; a substitution is proposed in writing, never made quietly
- Build the samples to the confirmed drawing and materials
- Inspect and test to the agreed scope, with photos and measurements where you want them
What you get
- Samples built to your drawing, for your own evaluation
- Any design change raised with you and confirmed first; your design is not altered on our side
- A quotation for the next step when you want one, and none when you do not
Prototyping can be bought on its own; there is no obligation to order a run afterwards. Where a drawing, a specification or a manufacturability question needs clarifying, we take it up with the engineers directly and come back to you with the answer.

ODM — Custom Design & Manufacturing
“I know what it needs to do. I need help designing it.”
Start with your functional requirements, interfaces or an early concept. Working with our engineering and manufacturing partners, we develop the cable or harness design, build prototypes and refine it for your product.
Who it is for
Teams with a product to wire and no finished production drawing yet. ODM stands for original design manufacturing: the design and the build happen on our side, and the product goes to market under your brand.
What you can bring
- The interfaces: what connects to what, and any connector already fixed on either end
- Installation space, routing and the environment the cable lives in
- Electrical needs: current, voltage, signals, shielding
- Reference photos, a sketch or an existing part; anything that shows the intent
What we take on
- Work directly with our engineering partners to turn your requirements into a manufacturable cable or harness design, with joint technical discussions arranged when needed
- Select connectors and wire, define the pinout, and work out the routing and assembly requirements
- Build the first prototypes and iterate on them: each revision confirmed with you and carried into the drawing
What you get
- A manufacturable design, with the drawings and BOM agreed for the project
- Prototypes to evaluate, then the same design built for your runs
- Engineering fees, the scope of revisions and the documents delivered, set out in writing before work starts
The scope is the cable or harness: connectors, wire, pinout, routing and assembly. Enclosure mechanics, PCBs, firmware and control software stay with your team. Your customers see your brand; Interconnix stays behind it.

Prototype-to-Mass Production
“I need a partner from the first prototype through production.”
Keep your cable assembly project moving through prototype revisions, pilot builds and mass production, with agreed specifications and changes carried forward from one stage to the next.
Who it is for
Projects that will go beyond samples: a product heading for pilot builds, mass production and repeat orders. It follows on from either service above, or picks up a design you already hold.
What you can bring
- The current drawing and BOM, at whatever revision they are
- Prototype results and the changes they call for
- Expected quantities, by stage if you know them
- Test, documentation and delivery requirements for the production parts
What we take on
- Prototype validation and design iteration until the design is confirmed
- A pilot build once the design is confirmed, with a first article you approve before the run
- Material and tooling planning for the quantities that follow
- Mass production and repeat orders to the approved revision
- Drawing, BOM and revision management, so every lot traces to the version it was built to
- Inspection, testing and delivery to the agreed plan
What you get
- One design record that stays current from the first prototype to the latest lot
- Production quantities quoted and built against the approved revision
- Design changes, test requirements and production versions confirmed with the engineers and recorded in writing
Prototypes come first and are yours to evaluate. The first article and the pilot run follow once you confirm the design, and mass production once you approve the pilot. You confirm each stage before the next one starts.

One contact. Fewer handoffs.
Interconnix is your day-to-day contact for requirements, quotations, changes and delivery. We coordinate directly with our manufacturing partner and involve the relevant engineers when technical clarification is needed. Joint technical meetings can be arranged where useful.
One point of contact
You know who to call and who is responsible. Interconnix handles the requirement, the quotation, the schedule and the delivery, and keeps what was agreed in writing.
A short communication chain
We coordinate directly with our manufacturing partner, keeping questions, decisions and updates from passing through multiple intermediary layers.
Joint discussions when needed
When a technical issue needs a joint discussion, we can arrange a meeting with the relevant engineers.
Long-lead components holding up your prototype?
When specified components are difficult to source, we can evaluate alternatives — including China-made options — to help you progress with proof-of-concept testing. Proposed substitutions are reviewed against your test objectives and used only with your approval.
An alternative suitable for a proof of concept may still need further validation before production.
- 01Agree what this round has to proveThe test objective decides which differences in a part matter for now and which do not.
- 02Find what can be sourcedConnectors or wire available in the time you have, including China-made options.
- 03Show the differencesBrand, part number and specification beside the original, and what each difference means for the current test.
- 04Use it only with your approvalThe substitution is recorded in that prototype's revision, so it is never mistaken for the production part later.
- 05Confirm the production materials laterFinal materials are confirmed for production, with whatever validation applies to them.
Common questions about the services
Do I have to start with build-to-print and work through all three?
No. They are three ways of working, not a sequence. A prototype can be ordered on its own, an ODM project can stop at the design and samples, and production support can start with a design you already hold.
Can I order prototypes without committing to production?
Yes. Prototypes are quoted and built on their own. If the design goes on to a run, the first article and the pilot build are quoted when you are ready for them.
What does ODM mean here?
Original design manufacturing: you bring the requirement, the cable or harness is designed and built on our side with our engineering and manufacturing partners, and the product goes to market under your brand. The scope is the cable or harness; enclosure mechanics, PCBs and firmware stay with your team.
What is agreed before an ODM project starts?
Engineering fees, the scope of revisions, the documents you receive and how the drawings may be used are set out in writing before work starts, so the deliverables are not a surprise at the end.
Who does the engineering work?
The engineers at our manufacturing partner, the people who will also build the assembly. You work with Interconnix; we coordinate with the partner and consult those engineers when a question needs their input.
How is technical communication handled?
Interconnix is your main point of contact. We coordinate with our manufacturing partner and consult the relevant engineers when a question requires their input. If a joint technical discussion would help, we can arrange one.
What happens between a prototype and mass production?
You evaluate the prototypes and the design is revised until you confirm it. Then a first article is built and approved by you, a pilot build follows, and mass production and repeat orders are built to that approved revision.
What if a specified component has a long lead time?
We look for alternatives you can test with, including China-made options, and show you the differences in brand, part number and specification. A substitution is used only with your approval, and a part that is fine for a proof of concept may still need validation before production.
How is the lead time determined?
By the design, the materials and any tooling. Connector availability usually decides it, so materials are checked early and a date is confirmed in the quotation rather than quoted as a blanket number.
