Build to Sample
Build to sample means Linkssor reverse engineers a physical harness. We measure cut lengths and branch geometry, identify connector housings,.

Build to Drawing — Wire Harness Manufacturing
Build to drawing means Linkssor manufactures strictly to the design record you supply — drawing, BOM and specification. We return a DFM review before quoting, run first-article inspection, verify crimp height and pull-out force per lot, and issue a certificate of conformity against the drawing revision we built to.
Build-to-print looks simple and is not. The failure points are always the same: a drawing revision that is not the one production is holding, a connector part number that has an unstated plating option, or a cut length with no tolerance. Our DFM review exists to surface those before tooling.
How the build-to-drawing process runs
Drawing intake and revision control
We register the drawing revision, list every document received and confirm which revision is authoritative before any material is ordered.
DFM review before quotation
An engineer reviews gauge, connector availability, tolerance achievability, branch strain relief and test feasibility — and issues questions in writing.
Process design and fixture build
Cut lengths, crimp settings, forming-board and test fixture are defined from the drawing, not from a similar part built previously.
First-article inspection
First-off units are dimensionally inspected and crimp cross-sections are analysed; the FAI report is sent for your approval.
Volume production and documentation
Once the FAI is approved the criteria are locked. Production runs to the same process settings with lot-level traceability.
What a build-to-drawing package should contain
- Drawing with revision number, date and units declared
- Cut lengths and branch dimensions with tolerances
- Connector and terminal part numbers, including plating and seal options
- Wire specification: gauge, conductor class, insulation material and colour code
- Sleeving, conduit and tape specification per branch
- Test requirement: continuity only, or insulation resistance and HIPOT
- Labelling and marking convention
- Applicable workmanship standard (IATF 16949, customer or national standard)
- Packaging and delivery schedule
What we do differently on a build-to-print part
- We quote the revision, not the concept — Quotations reference the drawing revision number so a later drawing change cannot be argued about.
- Crimp is a controlled parameter — Crimp height, pull-out force and cross-section are specified and verified per lot — not sampled by eye at setup.
- Tolerances get an honest answer — If a stated tolerance is not achievable with the specified connector and process, we say so before you place the order.
- Change control is documented — Any deviation is raised as a written request; the part is not silently adjusted to make it buildable.
FAQ
Which drawing formats do you accept?
PDF, DWG, DXF, STEP, IGES and Excel BOMs. Vector PDF or native CAD is preferred because it removes transcription risk on dimensions.
Do you build to imperial units?
Yes. Drawings in inches or millimetres are both handled, with the unit declared on the drawing and carried through to the inspection report.
What if I need a change after first article?
We raise a documented engineering change, re-run first-article inspection on the affected dimensions and re-issue the report. Volume is held until approval.
Can you supply the drawing for us instead?
Yes — where you do not have a design record, see Build to Sample, where we measure and produce a drawing for your approval.
