Custom Wire Harness FAQ

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.

Send the required quantity, shipment date, approved drawing and bill of materials for a capacity and material review. An urgent request needs written confirmation of what can be supplied and when. Do not assume that a particular quantity, such as 50,000 assemblies in one week, is available without a project review.

Payment method, deposit, balance timing and any letter-of-credit requirements are agreed in the quotation and sales contract. Shipping terms are a separate commercial decision. Confirm the named place, Incoterms rule and version, freight responsibility, insurance and import obligations before placing the order.

Ask for prices at the order quantities you are comparing. Pricing depends on component purchasing, tooling, setup, assembly work, inspection and packaging. Any discount, sample credit, spare quantity or freight contribution must appear in the written quotation. Material substitutions require technical approval and must not be selected on price alone.

A drawing is the clearest starting point. A sample, photograph or sketch can support an initial discussion, but connector identity, circuit connections, dimensions and operating requirements still need confirmation. The manufacturing drawing, bill of materials and test requirements should be approved before sample or production release.

Specify connector and terminal part numbers, cavity assignments, wire gauge and insulation, branch lengths and measurement datums, breakout locations, labels, protection and acceptance criteria. Identify the revision and permitted substitutions. For layout decisions, use the customization process for the next review steps.

Provide the manufacturer and exact part number for each connector, terminal, seal and accessory. Specify the wire construction, insulation, temperature range, voltage requirement and environment as applicable. Availability, sourcing route, tooling and alternatives must be reviewed for the order. A connector brand reference does not imply manufacturer authorization or universal compatibility.

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.

Crimp acceptance should follow the specified terminal and wire combination, tooling instructions and project acceptance criteria. Relevant checks can include strip length, crimp dimensions, conductor position, insulation support and pull testing. Automation alone does not prove conformity. Ask which checks and records apply to your selected terminal and wire.

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.

Agree the inspection plan, acceptance criteria, sampling or test coverage, lot identification and record-retention requirements in the order. Ask whether the assembly needs individual serial numbers or batch traceability. Inspection frequency and available records must be confirmed for the project; a general website statement is not a substitute for the approved control plan.

Review the certification documents for the legal entity, site, scope and validity dates, and request current copies where required. State any product-specific standard and revision in the RFQ. A quality-management certificate does not automatically certify an assembly, material or performance rating.

Identify the drawing revision and affected quantities when requesting a change. Confirm component impact, tooling, verification, price and shipment effects before implementation. For a quality concern, provide the order or lot reference, photographs, failure description and test evidence so the issue can be reviewed against the agreed acceptance criteria.

Contact JinHai to discuss the purpose, preferred dates and areas you need to review. For a catalog or product inquiry, describe the application and connector family. Published examples are a starting point; the final assembly configuration, commercial terms and supporting evidence must be confirmed for your order.

Gunakan tombol contact form to submit your requirements. Send drawings, photographs or specification files to sales@jinhaiharness.com and include the same project reference. Add your quantity, application, drawing revision and target schedule so the technical review can address the right questions.
