Custom Development — From Drawing, Sample or Open Question

Most projects do not arrive as a finished drawing. They arrive as a mating connector and a problem, a sample that keeps failing, or a spec written before anyone checked what was manufacturable. Our job starts before the quote: turn whatever you have into an assembly definition that can be built repeatedly, at your volume.

Start from where you actually are

Three entry paths. All of them end in the same place — a defined assembly with an agreed inspection basis — they only differ in what you hand us first.

01You have a drawing or BOM

Build-to-print quoting from your documentation, with engineering questions returned before pricing is locked.

The development sequence

Six stages. Each one has a defined output, so you always know what you are getting and what the next decision depends on.

#	Stage	What happens	What you receive
01	Input	Drawing, sample, application notes, environment and target quantity are logged together	Acknowledgement and a list of what is still missing
02	Engineering review	Interface, pinout, cable construction, molding, tooling and test needs assessed as one system	Written DFM questions and risk flags
03	Quotation	Construction, tooling and validation basis aligned to the approved definition	Itemised quote: piece price, tooling, test scope
04	Prototype	Physical samples built for fit, function and finish	5 pcs + dimensional report + photographs
05	First article	Production-intent parts made on production tooling and the production process	FAI report to your agreed format
06	Production release	Approved information carried into repeat manufacturing	Locked specification, inspection basis, revision control

Service — the record follows the part

Every stage should produce a useful next decision, and the record of it should stay with the assembly rather than with whoever sent the last email.

Commercial communication, technical clarification and production feedback are kept against the same assembly definition. When a repeat order arrives a year later, it is built to the requirements you approved — not to the ones someone happens to remember.

Before quotation

Interfaces, application conditions and acceptance needs are clarified before a price is given, so the quote reflects what you actually need.

During development

Open points, sample feedback and approved changes are tracked in one place, with the reason recorded alongside the change.

After release

Repeat orders and revisions stay tied to the controlled requirement set, so a rebuild matches the build you signed off.

What changes between prototype and production

A prototype that fits is not a design that repeats.

Before release we confirm four things: the process that made the sample is the process that will make the order; crimp tooling, mold and fixtures are production-intent rather than bench-made; inspection points that were checked once are documented as routine; and any dimension that was “close enough” at sample stage is either toleranced or fixed.

Skipping this conversation is how a perfect first article becomes a failed third batch.

Change control

Every revision carries a reference tied to your part number.
Changes to connector, cable, pinout, mold geometry or test scope are confirmed in writing before implementation — not after.
Obsolete revisions are retained, so a repeat order in two years matches the two-year-old build, not the latest guess.
Tooling is stored and maintained free of charge for 36 months after your last order; the tool itself is yours.

Drawings, IP and confidentiality

We sign mutual NDAs before receiving drawings — you do not have to send the file first and ask later. Tooling built against your paid development belongs to you. We do not sell your geometry to other customers, and we do not publish customer-identifying case studies without written approval.

That last point is worth stating plainly: if you are wondering why a custom cable supplier has no recognisable customer logos on its website, it is usually because their customers asked them not to. We will do the same for you.

See how our tooling is built and owned, or read the FAQ for commercial terms.

Bring us the drawing, the sample or the unanswered question.

Send what you have — a STEP file, a BOM, a failed part or a paragraph describing the problem. We will tell you what is missing in one round, not six emails.
