Custom Wire Harness & Cable Assembly Manufacturer

Send the drawing and revision, circuit or pinout list, wire sizes, connector and terminal part numbers, branch lengths, quantities and application requirements. Include the operating environment and target schedule. If a specification is missing, describe the open question rather than assuming an equivalent component. See our customization process before submitting an RFQ.

MOQ is confirmed for each design after reviewing components, tooling, assembly work and purchasing constraints. Prototype quantities and production quantities may have different cost structures. Send your expected order quantity and annual demand so JinHai can confirm the applicable minimum and quotation; this page does not establish a fixed MOQ.

Request samples against an agreed drawing revision and acceptance plan before releasing production. Confirm sample quantity, component availability, tooling, charges and any credit against a later order in the written quotation. Sample approval should cover fit, connector orientation, branch dimensions, pinout and the tests required for your application.

A delivery schedule depends on drawing approval, connector and wire availability, tooling, sample verification, order quantity and shipping arrangements. Request separate dates for engineering review, sample completion and production shipment. JinHai must confirm these dates for the specific order; generic lead-time ranges are not a delivery commitment.

A typical sequence is specification review, material preparation, cutting and stripping, termination, subassembly, routing and protection, inspection, electrical testing and packaging. The applicable process depends on the design. See JinHai’s production process and agree the controls required for your assembly before release.

Continuity testing checks whether the specified electrical paths are connected and can identify opens, shorts or incorrect pin assignments when the fixture and program are configured accordingly. It does not by itself establish insulation performance, current capacity, sealing or service life. Agree the circuit map, limits and required test coverage before production.
