Engineered Interconnect Systems for OEM Manufacturing Programs

Can you build a sample before the bulk order?

Yes. Before mass production we build a sample and send it to you for approval. A sample run is usually 1–3 pieces, so you can test fit and function before releasing the batch order.

The sample matches the final production harness, so what you approve is what you receive in volume.

Sample cost depends on how complex the drawing is, and sample shipping is charged by the estimated weight and packed size.

Are harnesses tested before shipment, and which tests are done?

Following the standard, we generally run three checks: visual inspection (terminal crimp condition and the overall appearance of the assembly), pull test, and continuity test.

Harness production and inspection follow IPC/WHMA-A-620. Our cable testers check resistance, continuity, insulation, open circuits and shorts. We can send our inspection and laboratory equipment list on request.

If you need tests beyond these, tell us the test and pass criteria before production so they can be discussed and agreed in advance.

Which quality certifications do you hold, and can you send copies?

Hebei Cloom (Luquan, Shijiazhuang), the group’s harness manufacturing company, holds ISO 9001:2015, IATF 16949 and ISO 13485:2016 certificates. When a customer asks, the sales team sends copies of the certificates for supplier documentation.

The certificates are issued to the Hebei Cloom plant in China.

Can you use UL-certified wire in the harness?

Yes. We can build with UL-certified wire and cable styles, for example the UL2464 AWM style, and send the datasheet of the wire we plan to use. If you need a UL-certified cable made to a custom construction, that is possible with an additional customization cost.

The UL marking belongs to the wire or cable itself. It is not a UL listing of the finished harness. Put the UL style, gauge and voltage rating you need on the drawing or BOM so we quote the right material.

Will you build with the wire brand and connectors on our drawing?

For wire, yes. When your drawing specifies a wire brand and type, for example because of a certification requirement, we follow the specified original brand and type strictly.

For connectors, we can build cable assemblies with JST connectors on request. Whether another connector brand can be used is confirmed per enquiry, so list the manufacturer part numbers in your BOM.
