  • PPAP Level 3 available for automotive programs
  • BOM traceability to wire spool and terminal lots
  • Revision control for OEM engineering changes

IPC/WHMA-A-620 workmanship for regulated harnesses

Medical, industrial and robotics harnesses can be built with IPC/WHMA-A-620 certified operators when reliability and documented inspection matter more than lowest piece price.

  • IPC/WHMA-A-620 certified operators
  • Continuity, hi-pot and insulation resistance on every harness
  • FAI and inspection records available by lot

Sample of who we ship to today

Customer names protected under NDA. PPAP / FAI sample packages available for procurement review on request.

Automotive EV OEM

An EV automotive OEM required an urgent NPI prototype run for a new vehicle harness package, with a small prototype batch needed on a tight deadline. The initial batch was delivered on time after connector authorization, expedited procurement and fast-tracked production.

Automotive EV NPI

An EV automotive client frequently updated harness designs during the NPI phase, issuing multiple deviation files. A strict deviation management process and dedicated technical liaison reviewed every deviation file against active POs before production release, incorporating continuous design updates without halting production.

Marine Wire Harness OEM

A marine OEM ran multiple RFQs over several weeks alongside a detailed technical exchange. The team maintained fast response times, proposed advance ordering and buffer stock for recurring delivery needs, secured the tooling order and moved the program into prototyping.

Why OEMs choose us

Built for engineers who don't accept “close enough”

  • Engineer-to-engineer. Every quote routes through a harness engineer, not a sales rep. Your DFM feedback comes from someone who's built the variant.
  • No black-box assembly. Your harness stays inside our IATF 16949 lines — we don't farm assembly to third parties. Every operator is IPC/WHMA-A-620 certified.
  • PPAP-level documentation on automotive programs by default, FAI on every NPI build, traceable BOM down to wire spool lot codes.
  • Cirris / DIT-MCO 100% test. Every harness — prototype or production — runs through full continuity, hi-pot and insulation resistance tests before shipping.

FAQ

Common questions before placing your first order

What is a custom wire harness manufacturer?

A custom wire harness manufacturer designs and builds bundled wire and cable assemblies to your exact schematic, connector list and routing. We cut, strip, crimp, splice, overmold and electrically test assemblies to the approved workmanship and inspection plan so the harness ships ready to drop into your equipment without rework.

Is there a minimum order quantity (MOQ)?

No. We accept single-unit prototypes and run pilot batches of 10–50 harnesses while you validate the design. Production builds are quoted around the approved BOM, tooling, test fixture and release schedule.

How fast can you deliver a prototype?

Standard prototypes ship in 48 hours from a signed-off drawing or BOM. Complex harnesses with overmolded connectors or custom tooling typically ship in 5–7 days.

Which industries do you serve?

Automotive (IATF 16949 + PPAP), medical devices (ISO 13485), industrial automation, robotics, aerospace and defense (mil-spec), EV powertrain (HV harnesses) and marine applications. Every program is gated through DFM review before quoting.

What certifications do you hold?

ISO 9001, IATF 16949, ISO 13485 and IPC/WHMA-A-620 certified operators for workmanship. PPAP documentation is available on automotive programs. Audit reports are available under NDA.

Where are you located?

Engineering and DFM in the US and EU; manufacturing across IATF 16949 lines in China and the Philippines (Cavite). After-sales support in Melbourne (AU/NZ) and Seaford VIC.
